Semrush Introduces LLM Gap Analyzer to the App Center

April 21, 2026
Semrush Introduces LLM Gap Analyzer to the App Center

The LLM Gap Analyzer app helps marketers understand how and why their content appears in large language models, and just as importantly, why it does not.

LLM Gap Analyzer is now part of the Semrush App Center. Marketing teams can examine where competitors are being cited, where existing content is missing context, and how those patterns affect brand discoverability across AI platforms.

Find and Fix Content Gaps for Better AI Visibility

AI-generated answers are quickly becoming a core search layer. 
According to McKinsey & Company, 44% of agentic search users already prefer AI tools over traditional search engines. A recent Semrush study shows that, on average, traffic from LLM-based search converts 4.4 times more than traditional organic search traffic.
Marketers increasingly need brand visibility in LLM results. LLM Gap Analyzer shows how AI forms answers to specific queries, where the information comes from, and why a brand’s articles are not used in responses.

What LLM Gap Analyzer Offers

Rather than treating AI answers as a black box, the tool translates them into observable signals:
  • AI answer breakdown: Check how AI has built a response to a prompt and trace it back to the sources used.
  • AI Overview insights: Understand why Google AI Overviews select specific pages as sources.
  • Content gap detection: Compare brand articles to cited sources to know what information a particular piece of content is missing.
  • Improvement guidance: Get clear suggestions to strengthen brand content and get more citations.
  • Information analysis: Spot opportunities to correct gaps, inaccuracies, and missing context in AI answers.

Ideal for Teams, Agencies, and Content Strategists

LLM Gap Analyzer is built for any specialist or business prioritizing content visibility in AI:
  • SEO specialists and content strategists: Boost brand visibility by appearing as a source for LLMs.
  • Agencies: Show clients why their content isn’t performing across AI platforms and justify content strategies with clearer data.
  • Marketing teams: Protect organic traffic as zero-click results become more common.
  • Content experts and creators: Find data voids and build brand authority in LLMs through optimized content pieces.

Understand How AI Interprets Brand Content

LLM Gap Analyzer is a new diagnostic tool in the Semrush App Center, analyzing specific articles, keywords, and prompts. It maps content gaps and shows where competitor pages are consistently chosen as sources in AI systems.
AI visibility should not rely on guesswork. LLM Gap Analyzer helps to measure, identify, and shape AI search behavior instead of reacting to it.
