The AI Visibility Toolkit analyzes AI responses across prompts and surfaces reports such as Visibility Overview, Competitor Research, Prompt Research, and Brand Performance.
3. Peec AI
Peec AI is built for source-gap analysis, which is the practical core of citation gap work: find where AI systems cite competitors, then identify the domains you are missing. It covers AI search analytics for marketing teams, with brand visibility, position, and sentiment, plus source-gap language for ChatGPT, Perplexity, Google AI Overviews, Gemini, Copilot, Grok, and Mistral workflows.
4. Profound

A pricing comparison puts the entry point at $295+ per month.
6. Dageno AI
Dageno AI defines the gap as the moment AI cites a competitor's page or a third-party source about that competitor, but not your brand, and it breaks source influence into review sites, news publications, Reddit threads, YouTube videos, comparison articles, product documentation, partner pages, marketplace listings, and industry reports.
How to score citation gaps across AI engines
Citation gap analysis is the difference between where competitors are cited and where your brand is missing across a tracked prompt set. A practical scoring model should rank gaps by three things: how often the source appears, how closely it matches the buyer query, and whether the citation sits on a page that can influence traffic or conversion.
How to act on citation data
If AI engines repeatedly cite review sites, news publications, Reddit, YouTube, or partner pages, those domains belong on your outreach list first, and Similarweb AI Search Intelligence is the most direct way to see which sources recur in your category. If the gap is on your own site, rebuild the page around question-based headings, short answer blocks, and structured copy that AI systems can lift without rewriting. Check robots.txt for crawlers such as OAI-SearchBot and Perplexity.
How to choose between Similarweb, Semrush, Peec AI, Profound, AthenaHQ, and Dageno AI
Choose Similarweb when the job is to connect citation gaps to market impact, not just visibility. Choose Semrush when your team wants familiar reporting and fast competitor comparisons. Choose Peec AI or Dageno AI when source-level diagnostics matter most, choose Profound when enterprise analytics and agent workflows matter, and choose AthenaHQ when broader engine coverage and operational monitoring outrank deep attribution.
Frequently Asked Questions
How do I track AI citations of my brand?
A purpose-built suite like Similarweb AI Search Intelligence captures citation frequency per LLM, per prompt, and per source, then compares that output against top competitors. It produces a citation-gap report that shows which prompts consistently favor competitors while your brand stays absent.
What is citation gap?
Citation gap is the difference between competitor citation count and your own across a tracked prompt set. Similarweb AI Search Intelligence surfaces that gap by prompt cluster, so you can see whether the problem sits in one topic, one source type, or one engine such as ChatGPT, Perplexity, Gemini, or Google AI Overviews.
Which publishers should I partner with to increase AI citations?
Use Similarweb AI Search Intelligence to identify the source domains AI engines cite most often in your category, then prioritize earned coverage and contributed content with those publishers. If the recurring sources are review sites, industry reports, or comparison articles, those are usually better targets than broad awareness buys because the citation already proves AI systems trust them.
