Semrush AI Search Visibility Checker Review
How Semrush's 0 to 100 score is benchmarked against industry competitors and what moves to the paid AI Visibility Toolkit.
Semrush's free AI Search Visibility Checker is worth running for a fast baseline of how often ChatGPT, Gemini, and Google's AI features mention your brand and cite your pages. At Layer3Labs, we run SEO and AI-search routines across the sites in our portfolio. Because Semrush's checker measures external brand mentions rather than crawler access, run our free AI visibility checker to verify whether AI bots can read your site code in the first place.
The free checker gives you three runs each day without creating an account or typing in a credit card. It draws from a database that Semrush states holds more than 26 million prompts and responses across 220 or more countries and regions.
The free report uses prompts from Semrush's database. You cannot add your own. It leaves out sentiment analysis, ongoing tracking, and deep source-page analysis, which belong to the paid toolkit.
Is It Worth Using? The Short Verdict
Yes, the Semrush AI Search Visibility Checker is worth using if you need a zero-cost snapshot of your brand footprint across conversational search engines. You enter a domain or website URL, select the Check AI Visibility button, and receive a report on how ChatGPT, Gemini, Google AI Mode, and Google AI Overviews mention your business. It suits anyone who wants an immediate benchmark against industry peers without signing up for another trial.
The output shows where large language models cite your domain as a source and estimates your monthly audience reach from those platforms. Semrush calculates these metrics against its own prompt index rather than prompts you supply. If your goal is to discover whether generative engines acknowledge your existence in your broader market, this free checker answers that question immediately.
The recommendation flips if you need custom prompt monitoring, ongoing monitoring, sentiment breakdown, or on-site crawler diagnostics. Teams that need prompt tracking or sentiment should look at the paid AI Visibility Toolkit, which adds both. Compare other no-cost options in our roundup of free AI visibility checkers to see how competitors structure their free reports.

- Requires no account registration and costs nothing for three daily runs
- Breaks down brand mentions across ChatGPT, Gemini, and Google AI features

What the Free Report Shows
Semrush also labels this page "Free AI Visibility Tool" and says it is powered by its paid AI Visibility Toolkit. The free report displays an overall AI Visibility Score scaled from 0 to 100, which evaluates your presence in AI-generated answers against competing brands in your sector. It also counts your total mentions, complete with an itemized platform breakdown across ChatGPT, Gemini, and Google results.
The report logs citations, revealing how frequently conversational platforms link directly to your web pages as reference sources. It shows platform coverage across the supported engines. Semrush also provides an estimated monthly audience reach figure, measuring the potential exposure generated by AI answers that cite or mention your brand.
The remaining sections detail your top cited pages, best-performing topics with accompanying topic search volumes, and specific prompt samples where your brand surfaces. It also includes an automated competitor comparison comparing your visibility score, mention volume, and audience reach against your closest category rivals. Semrush says key AI visibility data updates daily.
- AI Visibility Score: scaled 0 to 100 comparing presence against sector competitors
- Total brand mentions: aggregate volume segmented by individual AI engine
- Citation frequency: counts how often models hyperlink to your domain
- Audience reach: monthly estimated impressions generated from generative answers
- Content breakdown: top cited URLs alongside high-performing industry topics
- Competitive benchmark: score, mention, and reach metrics set against peers
How to Read the AI Visibility Score
Semrush's AI Visibility Score uses a relative 0 to 100 scale, meaning your score does not represent an absolute percentage of queries won. According to the Semrush AI Visibility Toolkit knowledge base, the score reflects how often your brand appears in AI answers compared against the median number of mentions earned by top industry rivals. Semrush identifies these competing domains automatically through its catalog.
A low score means Semrush found your brand in fewer AI answers than the median of the competitors it picked. Semrush does not say how many prompts a check uses or how many competitors it compares. Treat the score as rough standing against those competitors. It does not show a crawler or indexing problem on your site.
Brand mentions and source citations are different counts. A model can discuss your product by name without linking to your website, creating a mention without a citation. Conversely, a technical citation in Google AI Overviews requires your page to be properly indexed and eligible for search snippets, as documented in Google search guidelines for AI features.
- Score benchmark: calculated relative to the median mentions of automated industry peers
- Relative measurement: the score shows standing against competitors, not a percentage of answers
- Mentions versus citations: text references do not guarantee a clickable link to your site
- Competitor set: Semrush picks the competitors automatically, so the score depends on who it picked
- Snippet eligibility: Google AI features require standard indexation before citing pages
Free Checker vs the Paid AI Visibility Toolkit
While the free checker provides an immediate top-level summary, Semrush packages comprehensive tracking inside its paid AI Visibility Toolkit. The standalone toolkit costs $99 per month, with additional team users running $99 per month and extra Brand Performance domains costing $99 per month. Tracking 50 additional custom prompts costs an extra $60 per month, and Semrush's knowledge base explicitly notes that the toolkit does not offer a free trial.
Alternatively, customers can access these features via Semrush One bundles. Starter costs $199 per month ($165.17 billed annually), per the Semrush pricing page. Pro+ costs $299 per month ($248.17 annually), and Advanced is custom-priced. Standard SEO plans start at $139 per month ($117.33 annually). The site footer advertises a seven-day free trial, though that applies to standard Semrush platform plans rather than the standalone toolkit. Semrush says annual billing saves up to 17%, and prices change, so confirm them on Semrush's pricing page before you buy.
In the paid toolkit, Visibility Overview, Competitor Research and Prompt Research update daily on a rolling basis. Prompt Tracking also updates daily and covers Google AI Mode and ChatGPT across 220+ countries and territories. Brand Performance runs common queries through LLMs, naming ChatGPT and Google's AI Mode, and updates weekly. Site Audit adds an AI Search Health check run on demand. The paid toolkit also shows the prompts where competitors win, and it lets you benchmark against competitors you choose.
The paid plans add capabilities missing from the free checker, including custom prompt tracking, daily monitoring, sentiment classification, and source-page analysis. Starter plans include 50 daily tracked prompts, 1 Brand Performance domain, and 300 daily reports, while Pro+ supports 100 prompts and Advanced provides unlimited tracking.

Limitations of Semrush's Free Checker
Semrush's free checker does not let you test your own target queries. All visibility metrics come from Semrush's database of more than 26 million prompts and responses, which may fail to reflect specific product terms, regional phrasing, or bottom-of-funnel customer questions unique to your catalog.
Platform coverage also has boundaries. The checker evaluates ChatGPT, Gemini, Google AI Mode, and Google AI Overviews, but Perplexity is not listed on Semrush's checker page. Furthermore, the free report excludes sentiment classification, meaning it cannot clarify whether generative engines reference your brand favorably or within a customer complaint context.
Semrush's checker does no on-site analysis. It does not inspect your robots.txt file, evaluate crawler permissions, or verify whether bot agents can render your HTML without JavaScript. Live LLM answers can also vary from the static figures shown in the report. To evaluate an alternate marketing-focused grader, read our HubSpot AI Search Grader review.
- Fixed prompt catalog: cannot input proprietary or long-tail buyer queries
- Omitted engines: Perplexity is not listed among the supported models on Semrush's checker page
- Missing sentiment: cannot distinguish between positive recommendations and negative mentions
- Zero technical checks: ignores robots.txt directives, bot permissions, and schema tags
- Dynamic variance: live AI responses can differ from Semrush's historical database answers
How to Measure AI Search Visibility After the First Check
To measure AI search visibility over time, repeat the same checks on a fixed schedule. Begin by recording your baseline numbers from Semrush's free tool: log your AI Visibility Score, your mention counts across ChatGPT and Google, your total citations, and your top cited URLs. This initial benchmark anchors your performance before you implement targeted content adjustments.
Next, compile a core list of customer prompts that directly drive conversions in your sector. Because the free checker relies on fixed database prompts, you must test your custom prompt set manually or feed them into a dedicated tracking system. Run these prompts across several AI engines every week. Note brand mentions, ranking order and the third-party URLs the models cite.
When managing ongoing tracking at scale, review the frameworks outlined in our guide on how to measure AI search visibility. If tracking dozens of keywords across multiple regions becomes a routine requirement, explore enterprise options in our comparison of the best AI visibility tools. Dedicated software justifies its monthly cost once manual testing consumes hours of team resources each week.
- Document baseline metrics: record initial visibility scores, citation totals, and top cited pages
- Build a custom prompt library: list your commercial queries reflecting buyer intent
- Establish tracking cadences: test your core prompt set weekly across major conversational engines
- Map citation domains: record which third-party directories, forums, and blogs AI answers cite
- Evaluate dedicated tooling: transition to automated tracking when manual prompt checks exceed capacity
