When shoppers ask questions on ChatGPT, Google AI Overviews, or Gemini, they’re often looking for quick, trustworthy recommendations. If your brand isn’t appearing in those AI‑generated answers, you’re missing out on a powerful channel of discovery. A free AI visibility audit from Semrush lets you see exactly how often your brand shows up, whether AI systems can access your content, and how you stack up against competitors—all in under half an hour.
Why AI Visibility Matters
AI assistants are becoming the first stop for many buyers. They sift through vast amounts of data and deliver concise, relevant suggestions. When a user asks, “What are the best trail‑running shoes for wide feet?” the AI will pull from its knowledge base and recommend a handful of brands. If your brand is missing from that list, the opportunity to influence the purchase decision disappears.
In today’s digital landscape, visibility is no longer just about search engine rankings. It’s also about being recognized by the next generation of search tools. A brand that dominates traditional SEO but is invisible in AI responses is effectively invisible to a growing segment of consumers.
What the Free Audit Reveals
The audit answers three core questions that can help you pinpoint gaps and prioritize action:
- Is your brand appearing at all? The Domain Overview shows whether AI platforms mention your brand when answering category questions. A zero score signals a visibility problem that needs immediate attention.
- Can AI systems access your content? The Site Audit’s AI Search Health score highlights technical barriers—such as blocked crawlers or poorly structured content—that prevent AI assistants from finding and using your material.
- How do you compare to competitors? The Free AI Brand Visibility Tool compares the frequency of your brand’s mentions against those of rivals. If competitors appear three to five times more often, they’re shaping buyer perceptions before you even have a chance to respond.
By answering these questions, the audit tells you whether AI visibility gaps are costing you awareness and consideration.
Step‑by‑Step: Running the Audit
Below is a straightforward workflow that takes less than 30 minutes. All you need is a free Semrush account.
- Log in to Semrush. If you don’t have an account, sign up for the free tier.
- Navigate to the AI Visibility section. You’ll find it under the “SEO” menu, labeled “AI Visibility Audit.”
- Enter your domain. Type the URL of the website you want to audit and hit “Start Audit.”
- Review the Domain Overview. This snapshot tells you whether AI platforms mention your brand. A score of zero means you’re invisible.
- Check the AI Search Health. This part of the Site Audit shows technical issues that could block AI crawlers. Fix any flagged problems—such as disallowing robots.txt or correcting broken links.
- Compare with competitors. Use the AI Brand Visibility Tool to pull a list of competitors in your niche. The tool will display how often each brand is cited in AI answers.
- Export the report. Save the findings as a PDF or CSV for future reference or to share with stakeholders.
Once you’ve completed these steps, you’ll have a clear picture of your AI presence and a roadmap for improvement.
Bridging the Gap Between SEO and AI Visibility
Traditional SEO audits focus on rankings, keyword gaps, and organic traffic. AI visibility audits, on the other hand, measure how often your brand appears in AI‑generated answers—mentions, citations, sentiment, and brand inclusion across platforms like ChatGPT, AI Overviews, and Gemini.
Both audits serve the same ultimate goal: to be found when people search. However, they look at different layers. A site that
