123
301 redirect – An HTTP status code to indicate a permanent redirect forwarding one URL to another. Once a 301 redirect is added to a page, all users and bots that go to that page will automatically be sent to the redirected page. These redirects can help a website retain SEO value from a backlink going to a page that no longer exists.
302 redirect – An HTTP status code that indicates a temporary redirect, similar to a 301 redirect. The main difference between the two redirects is that a 301 is permanent, and a 302 is temporary. In terms of SEO, search engines will not pass along the trust signals from the backlinks pointing to an old page through a 302 like they would through 301.
307 redirect – An HTTP status code that indicates a temporary redirect – the resource requested has been temporarily moved to the URL given by the Location headers. The difference from 302 is that with the advent of HTTP 1.1, 307 has replaced it as a valid temporary redirect. While a 302 is a little vague, 307 states precisely that the requested URL has been moved to a temporary location and will be back in a while.
403 – An HTTP status code that indicates that a client is forbidden from accessing a valid URL. The server understands the request but can't fulfill it because of client-side issues.
404 – An HTTP status code that indicates when a webpage or document that can no longer be found by the server via the given URL.
500 Internal Server Error – An HTTP status code that indicates that the server, while working as a gateway to get a response needed to handle the request, got an invalid response.
502 Bad Gateway – An HTTP status code that indicates that the server has encountered a situation it doesn't know how to handle.
A
Access Log – A log file listing all requests for individual files made by people or bots on a website.
Ad Keyword – The query entered into a search engine that triggers Paid results.
Adobe Analytics – An analytics software made by Adobe that gathers data on real-time web analytics and marketing channels. It is similar to Google Analytics and can be used better to understand a website’s marketing segments and user interaction.
Ad Rank – A value used to determine your ad position (where ads are shown on a page relative to other ads) and whether your ads will show at all. Ad Rank is calculated using your bid amount, ad quality (including expected CTR, ad relevance, and landing page experience), the context of the person’s search, and the expected impact of extensions and other ad formats.
Affiliate – An affiliate site markets products or services that are actually sold by another website or business in exchange for fees or commissions.
Algorithm – A list of mathematical calculations and if/then statements that decide what action a computer program should take.
Alt Text – A description of an image, which usually isn’t displayed to the end user unless the image is undeliverable or a browser is used that doesn’t display images. Alt–text is essential because search engines can’t always tell one picture from another.
AMPs (Accelerated Mobile Pages) – A project supported by Google to create mobile versions of webpages that load as fast as possible in search. These pages are built using a special set of HTML to make the page light and easy to serve quickly.
Anchor Texts – Texts that appear highlighted in a hypertext link that ultimately brings you to a specific webpage when clicked. They are only used for text backlinks, for images, it’s an alt attribute (see Alt text).
Authority Score – A proprietary Semrush compound metric used to gauge a domain’s overall quality and influence on SEO. The calculation is based on three main facets:
Link Power: quality and quantity of backlinks
Organic Traffic: estimated monthly average of traffic
Spam Factors (Natural Profile): indicators of manipulation or spam in the link profile
Average Difficulty – A metric used in Semrush, located at the top of the keyword chart, is the combined average keyword difficulty of every keyword result in a Keyword Strategy Builder list. This can give you a general understanding of how hard it will be to run an SEO campaign in this keyword’s market. The higher the percentage, the more difficult it becomes to get a high ranking for each keyword.
Average Position – The average value of all your rankings for the keywords in your campaign. In Semrush Position Tracking, for any keyword where you aren’t ranking, it will be calculated as a ranking of 100.
B
B2B – Business to Business – A business model in which the companies involved are exchanging goods and services. Sales to consumers are referred to as “business–to–consumer” sales or B2C.
B2C – Business to Consumer. The term business–to–consumer (B2C) refers to a business model of selling products and services directly between a business and consumers who are the end–users of its products or services. Most companies selling directly to consumers can be called B2C companies.
Backlinks – Incoming links to a website or web page from another resource.
Beta – A term used when software is in the final testing phase before being fully released to customers.
Black Hat SEO – The use of unethical or manipulative techniques to increase a website's search engine rankings.
Bot (robot, spider, crawler) – A program that performs a task more or less autonomously. Search engines use bots to find and add web pages to their search indexes. Spammers often use bots to “scrape” content to plagiarize it for exploitation by the Spammer.
Bounce Rate – An Internet Marketing metric that tells you the percentage of users that land on one page of a website and then leave the site without viewing any other pages.
Breadcrumbs – Website navigation in a horizontal line above the main content, which helps the user to understand where they are on the site and how to get back to the root sections.
C
Call to Action (CTA) – What you want your target audience to do after receiving your marketing message. The call to action (CTA) clearly articulates the next step. Some examples are: “Learn More,” “Contact Us,” “Shop Now,” “Follow Us,” and “Sign Up.” A/B testing offers a great opportunity to experiment with different calls to action and optimize your messages with the CTAs that get the best audience response.
Canonical URL – A solution for solving issues related to duplicate content. If you have two webpages on your site that have duplicate content (for example, example.com/shoes/red and example.com/shop/red–shoes), making one of them the canonical URL tells search engines you want that page to be the one displayed in search results over the other. The html element for this would look like:
<link rel=canonical href= “https://example.com/shoes/red” />
Carousel – A SERP Feature consisting of a set of scrollable images displayed near the top of a SERP. The Image Carousel differs from the standard image result in that the Carousel will bring you to a new SERP for the image that you select.
Citation Building – The process of securing mentions or citations of a business's NAP (Name, Address, Phone number) and other relevant information across various websites. These citations serve as references to the business and are commonly found on online directories and review platforms.
Conversion Rate – The percentage of user actions taken after total clicks on a display ad or other digital asset. Your marketing strategy defines your actions, which commonly include clicking on a second link, downloading an asset such as a B2B (business-to-business) white paper, or signing up to receive special retail offers. The formula is: conversions/interactions = conversion rate. The higher your conversion, the more successful your campaign.
Click Potential – Metric used to gauge the predicted chance of getting a click-through to your website if your search result occupied the top position of the SERP. Click Potential depends on the presence of SERP Features that would hinder searchers from clicking on organic website results.
Clickstream Data – Data collected about the users while they browse through www in a web browser. This data can be used to understand how people navigate websites and pages on the Internet.
Com. – In Semrush, “Com.” stands for Competitive Density or the level of competition in Google Ads; this metric is measured from 0 to 1. The higher the number – the greater the competition.
Common Keywords – Keywords for which multiple domains rank among the top Google search results.
Competitors in Google Ads – The websites that rank for the same queries as the analyzed domain in Google Paid results.
Competitors in Organic Search – Sites that compete with the analyzed website in organic search results.
Content – The part of a web page intended to have value for and be of interest to the user. Advertising, navigation, branding, and boilerplate HTML are not usually considered to be content. Page content refers to all the information contained in a website. Page content can be displayed as text, links, images, audio, animation, or videos. Search engines have a limited ability to recognize images, animation, video, and audio. In these instances, search engines use file names or alt attributes to determine the contents of a page. Therefore, important information needs to be given in text–form to make it accessible to search engines.
Content Management System (CMS) – Programs such as WordPress, separate most of the mundane Webmaster tasks from content creation so that a publisher can be effective without acquiring or even understanding sophisticated coding skills if they so choose.
Content Marketing – A strategic marketing approach that entails creating and distributing content (blog posts, ebooks, videos, infographics, etc.) that is valuable to an audience. The valuable content attracts attention to a brand, builds an audience, and eventually helps grow revenue.
Conversion (Goal) – Achievement of a quantifiable goal on a website. Ad clicks, sign-ups, and sales are examples of conversions.
Core Web Vitals – An initiative by Google to highlight and describe a set of specific factors that shows URL performance grouped by status (Poor, Needs Improvement, Good), key metrics (CLS, FID, LCP), and URL groups (groups of similar web pages). The report is based on three metrics measured by actual user data: LCP, FID, and CLS.
Core Web Vitals (in Semrush) – A set of metrics in Site Audit that measure the loading performance, interactivity, and visual stability of a website. Specifically, it measures the Largest Contentful Paint (LCP), which judges the perceived load speed of the page, and the Cumulative Layout Shift (CLS), which quantifies the amount of unexpected layout shift in the visible page content. The third Vital is called First Input Delay (FID), which quantifies the user experience when the user first interacts with the page. However, this is a user-centric metric that cannot be recreated in a lab environment so, instead, Site Audit uses Total Blocking Time (TBT), which, according to Google, is an excellent lab-based proxy for FID.
Cost % – A Semrush metric (shown in both the Organic Positions & Advertising Positions reports) based on the overall Traffic Cost shown on the top left of your report. This represents how much of the overall cost being displayed comes from a given keyword. You will notice a Cost % for each keyword the queried domain ranks for. This represents how much of the overall cost being displayed comes from a given keyword.
CPC (Cost Per Click) – This metric represents how expensive the average advertising bid on that particular keyword would cost across the databases in Semrush. Each database that contains this keyword will be displayed along with the corresponding CPC in that region.
CPM (Cost Per Thousand impressions) – A statistical metric quantifying the average value/cost of Pay Per Click advertisements. M – from the Roman numeral for one thousand.
Crawl budget – Google defines crawl budget as “the number of URLs GoogleBot can and wants to crawl” on a website. It is affected by GoogleBot’s crawl rate and also how popular your pages are. Read more from Google here.
Crawler (bot, robot, spider) – A program that performs a task more or less autonomously. Search engines use bots to find and add web pages to their search indexes. Spammers often use bots to “scrape” content to plagiarize it for exploitation by the Spammer.
CRM – The practice of customer relationship management (CRM). The goals of CRM are to retain current customers, increase their spending, and convert prospects into new customers. CRM technology is used to manage information such as a summary of each interaction, indicators of intent to purchase, and purchase history. Analytics is also used to provide real-time insight into cross-sell and upsell opportunities at the individual customer level.
Cross Group Negatives – A method of optimizing a Google Ads campaign via implementing one ad group’s keywords as another ad group’s negative keywords. This prevents your ads in separate ad groups from competing against each other and harming the click-through rate/quality score.
CSS – Cascading Style Sheets is a stylesheet language that describes how HTML elements (e.g., color, fonts) should appear on webpages and adapt when viewed on different devices.
CTR (Click–through rate) – A metric that represents the percentage of clicks over impressions of a hyperlink or PPC advertisement, measuring how effective the link or ad is at attracting traffic.
Cumulative Layout Shift (CLS) – A measure of how much a webpage unexpectedly shifts during its life. For example, if a website visitor loaded a page and, while they were reading it, the banner loads and the page jumps down, that would constitute a large CLS score. It’s one of the key metrics used in Core Web Vitals.
D
Declined Keywords – In Semrush, these are keywords for which a domain has seen a decline in rankings but still remains in the top 100 ranking positions.
Destination Site – The site that the user visits directly after leaving a domain.
Direct Traffic – Traffic from users navigating to your site through a browser's address bar without going through a third party.
Disavow – If your backlink profile includes a high number of spammy, artificial, or low–quality inbound links that may be harming your rankings – and don’t have the ability to get them removed for a legitimate reason (e.g., the link exists on a site you have no control over) – you can use Google’s Disavow Tool tool to tell Google to ignore those links.
Disavow File – A list of backlinks that can be sent to Google in order to not take them into consideration when reviewing your site for a potential Google Penalty. If you have backlinks that may create the risk of receiving a Google Penalty, you can add them to a Disavow list and send the information to Google. In Semrush, you are able to create a disavow txt file in a Backlink Audit campaign.
Display Ads – A type of online advertisement that combines text, images, and a URL that links to a website where a customer can learn more about or buy products. These ads can be static with an image or animated with multiple images, videos, or changing text. Some display ads educate about the product, while others are designed to entertain and engage through simple games or puzzles. Banner ads are a common form of display ads.
Duplicate Content – Content that appears in more than one location on the Internet. Duplicate content can confuse search engines when deciding which page to index in a search, and in turn, this hurts the website’s SEO.
E
Ecommerce (electronic commerce) – Refers to the buying and selling of goods and services over the Internet. Ecommerce can be classified as business–to–business (B2B), business–to–consumer (B2C), or consumer–to–consumer (C2C).
Engagement rate (Social Analytics) – A total number of likes and comments on an Instagram or Facebook post, divided by the number of people who saw the post, multiplied by 100.
Engagement rate (Social Tracker) – A metric that shows how much engagement the social profile was able to get relative to the size of their audience and amount of posts. The formula we use to calculate the engagement rate number is:
<total engagement rate> = <total engagement> / <number of posts> / <audience> * 10000
Estimated Accuracy – A metric in the Traffic Analytics report that gauges the accuracy of the data presented. Since accuracy is dependent on the size of the data sample used to estimate the domain traffic, larger websites will generally have higher accuracy than less popular websites.
Estimated Traffic – A metric calculated by Semrush showing the estimated amount of traffic for a given website. There are three tools in Semrush that can estimate website traffic: Domain Analytics, Traffic Analytics, and Position Tracking.
In Domain Analytics, we present estimated organic and paid traffic based on the keyword positions that we see a website ranking for, the monthly volume of those searches, and average click-through rates per position. This estimation is solely based on traffic from Google search (either organic or paid).
The second place is Traffic Analytics and Market Explorer. This tool estimates the website’s total traffic based on clickstream data and the estimation takes into account traffic from multiple sources – search, direct, referral, social, and advertising traffic.
Position Tracking has an estimated organic or paid traffic metric that is based on the local search volume and the rankings that the domain occupies for keywords that are being tracked in the campaign. In this tool, estimated traffic represents a daily estimated number of visits.
F
Facebook Engagement – A sum of shares, likes, reactions (wow's, sad's, angry's, etc.), and comments made on all posts during the selected time period.
Featured Snippet – A SERP Feature that appears at the top of some Google search results and gives summarized answers to specific questions asked within Google.
Follow Links – Links that have an influence on the rankings of the linked site. These links help communicate a signal of trust in a web page to search engines.
G

Google Search Text Ads Traffic Price – Estimated monthly expenses for a Google Ads campaign.
Google AdSense – Google AdSense is a program run by Google through which website publishers in the Google Network of content sites serve text, images, video, or interactive media advertisements that are targeted to the site content and audience. These advertisements are administered, sorted, and maintained by Google.
Google Algorithm – Algorithms are a list of mathematical calculations and if/then statements that decide what action a computer program should take. The Google algorithm is the rules-based system Google uses to sort through hundreds of billions of websites to deliver relevant results to users’ search queries. The results are ranked in order of relevance on the search engine results page (SERP). The algorithm also uses personal context, such as your current location and past search history, to tailor the results.
Google Analytics (GA) – A free web analytics service provided by Google. It brings you detailed analytics about the activity on your website.
Google Looker Studio – A free online tool that lets you customize visual reports using data from various sources.

Google SE Traffic – The estimated monthly amount of visitors coming from the first 100 organic Google search results.
Google Search Console – A free analytics service (formerly titled Webmaster Tools) provided by Google that offers data on a domain’s search visibility and performance. It can be used in the assessment of a website’s crawlability and SEO.
GoogleBot (robot, spider, crawler) – Google’s program that performs a task more or less autonomously. Search engines use bots to find and add web pages to their search indexes. Spammers often use bots to “scrape” content to plagiarize it for exploitation by the Spammer.
H
Heading Tag – An HTML tag that indicates the levels of the headings within a webpage or document. These tags form a hierarchy from the highest level of importance/organization to the lowest:
from <h1> to <h6>
Using heading tags to relevantly indicate the levels of your webpage helps search engines understand your content better, which is good for SEO.
Heat Map – A map that represents the data and uses color to communicate areas of highest use or likelihood. A click map is a special type of heat map that shows which parts of web pages receive the most clicks. Using a scale of red (“hot”) to blue (“cold”), areas, where people look or click the most, are labeled with red. Web designers can combine the data from an eye-tracking heat map and a click map to position call-to-action buttons where they are most likely to be seen and clicked.
Historical Data – The data that allows you to perform research on keywords and domains from previous months. Domain Analytics and Keyword Analytics historical data goes back to January 2012. PLA historical data goes back to September 2013. Traffic Analytics' historical data goes back to January 2017.
Hreflang Tags – An HTML tag that helps search engines find and display content in a specific language when a website uses multiple languages. For example, Hreflang tags can help search engines in the United States find a page in English while a similar search performed in Mexico would return a page in Spanish. Hreflang pages also solve the problem of duplicate content penalties. Hreflang tags help search engines understand when content is customized to specific audiences rather than being duplicated as a search engine optimization (SEO) trick.
HSTS (HTTP Strict Transport Security) – a web security policy mechanism that helps to protect websites against protocol downgrade attacks and cookie hijacking. It allows web servers to declare that web browsers (or other complying user agents) should interact with it using only HTTPS connections, which provide Transport Layer Security (TLS/SSL), unlike the insecure HTTP used alone.
HTML (HyperText Markup Language) – A standard markup language or “markup” which is used to add formatting and web functionality to plain text for use on the internet. HTML is the mother tongue of search engines and should generally be strictly and exclusively adhered to on web pages.
HTTP – The Hypertext Transfer Protocol is a protocol for fetching resources transferred from a computer server to a web browser.
HTTPS – A secured protocol for fetching resources that uses a Secure Sockets Layer (SSL) to encrypt data transferred between a website and a web browser. HTTPS is a minor Google ranking factor.
I
Improved Keywords – In Semrush, these are keywords for which a domain is still ranking within the top 100 positions but has moved up in ranking since its previous position within the top 100 results.
Indexed Pages – A page that has been visited by a bot, analyzed for content and stored by a bot in its index.
Internal LinkRank – A Metric that measures the importance of website pages in terms of link architecture based on a 100-point scale (from 0 to 100). If a page is linked by many authoritative pages within your website, it will have a high LinkRank score.
IP address – A unique numerical label that identifies a device on the internet or local network.

You can find long tail keywords in Semrush by using the Keyword Magic Tool and adding filters for a number of words, keyword difficulty, volume, and more.
M
Manual Sanctions (Manual actions) – Google’s term for a penalty. Google will take manual action on a website after a human reviewer (i.e., a Google employee) manually reviews a website to confirm whether it has failed to comply with Google’s Webmaster guidelines. Penalized websites can either be demoted or removed entirely from search results. Manual actions can be assessed to the entire website or just certain web pages. Manual penalties are noted in the Search Console.
Map Rank Tracker (in Semrush) – This Semrush Local tool tracks local business rankings on Google Maps, helping you see how your business ranks from different locations based on potential client searches. Once you establish your business location, set the number of map pins (map grid), and specify the search queries to monitor, the Map Rank Tracker generates a heatmap report illustrating your business rankings for each map pin.
Market Consolidation (in Market Explorer) – A measure of websites’ traffic in relation to the market they are in and is an indicator of the amount of competition among them. It is based on the Herfindahl–Hirschman Index and reflects the division of market share among market players.

Meta Description – A short description of a webpage implemented through an HTML tag in the <head> part of the page. This description is what appears under the title of a webpage on a search engine results page. In the written form the tag looks like:
<meta name= “description” content = “short description of the page here (no more than 160 characters).”/>
Meta Tags – Statements within the HEAD section of an HTML page that furnish information about the page. META information may be in the SERPs but is not visible on the page. It is very important to have unique and accurate META titles and description tags because they may be the information that the search engines rely upon the most to determine what the page is about. Also, they are the first impression that users get about your page within the SERPs.
Meta Title – A meta tag and an important part of website optimization, and it's distinct from the headline on the page itself. It acts as a name tag for the web page. The title is displayed on your browser tab and tells you what page you're on. Meta titles are also read by search engine robots and seen by users searching the web. Title tags are displayed on search engine results pages (SERPs) as the clickable headline for a given result and are important for usability and SEO. The title tag of a web page is meant to be an accurate and concise description of a page's content.
Microdata – A type of specification used to nest metadata within existing content on the page that is embedded in the HTML content in order to improve readability, and analyze elements of a web page. This type of markup language allows search engines to point out specific elements of a piece of content such as a product rating.
Minification – The process of minimizing code and markup involved in your web documents and scripts. As a result of minification, websites can see faster page loading times and improve their user experience.
Mirror Site – An identical site at a different address.
N
NAP (Name, Address, and Phone) – A term used to describe the most basic necessary information that a business should list online. Having a business’s NAP consistent across all online citations is an important factor in local SEO.
National Level Data – The data that takes into consideration an aggregate of search engine positions all over the country to provide search results that avoid bias from specific locations. Viewing national-level data is a way of gauging how you're doing against competitors on a national level.
Negative Keywords – Keywords that allow you to choose what not to target with a Google Ads campaign. Just like regular keywords in an ad campaign, negative keywords can be set with match types such as exact match, phrase match, and broad match. When you add a negative keyword to your campaign, your ads will not appear in the search results for that search. This practice helps advertisers save budget and maximize ROI.
Noindex – A command found in either the HEAD section of a web page or within individual link codes, which instructs robots to not index the page or the specific link.
Not–provided – A default placeholder that Google Analytics displays in the Keywords report to hide the most popular keywords that drive organic search traffic to a website. In order to discover these hidden keywords, you need to use a third-party tool like Semrush or Google Search Console. This was implemented by Google in 2011 in an effort to protect the privacy of searchers.
Number of Results – The amount of all search results in the search engine returned for a search query.
O
Online Directories – Websites that organize and list business information, allowing users to find and connect with businesses. They typically include details such as the business's name, address, phone number (NAP), website, and hours of operation, and may also feature customer reviews, services offered, and photos. Examples include Google Business Profile, Yellow Pages, and TripAdvisor.
Online Review Management – The process of tracking reviews across various platforms, actively engaging with feedback, reporting fraudulent reviews, and resolving complaints to uphold a positive online reputation.
Online Visibility – The overall presence of a business or brand on the Internet. Improving online visibility allows a business to reach more customers and make more money. This can be achieved through digital marketing campaigns, SEO, PPC, Public Relations, social media marketing (SMM), blogging, and outreach among other strategies.
