   How does the AI Visibility Checker work?

   The AI Visibility Checker asks AI platforms, including ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews, questions based on your target keywords, then checks whether your domain is mentioned, cited or linked in the answers. It combines the results into an AI visibility score, so you can see where you appear and where you don't.

   How can I check whether AI crawlers can access my site?

   Check two things: the robots.txt rules for AI user agents such as GPTBot, OAI-SearchBot, ClaudeBot and PerplexityBot, and how your server actually responds to those crawlers, since firewalls and CDNs can block bots that robots.txt allows. Our free AI Crawler Access Checker tests both for the main AI crawlers in one go.

   How do I calculate SEO ROI?

   Estimate the extra organic traffic SEO will bring, multiply it by your conversion rate and the gross profit per conversion, then compare that profit with what you spend over the same period. Because SEO builds gradually, include a ramp-up period and look at payback time and break-even traffic growth, not just one ROI percentage.

   Find which of your important keywords show an AI Overview, then compare the expected click-through rate for your ranking position with and without one. Multiply the difference by each keyword's search volume to estimate the clicks lost. Our free AI Overviews Traffic Loss Calculator does this with published click-through research and shows the result as a range.

   What is organic traffic value?

   Organic traffic value is what your unpaid search clicks would cost if you bought the same clicks with Google Ads. It's calculated by multiplying the clicks each keyword brings by that keyword's cost per click and adding them up. It's a useful way to express SEO's contribution in money, but it isn't revenue.

   Do your calculators need an email or store my data?

   No email is needed to use the calculators or see results. The calculations run in your browser, and the figures you enter aren't sent to us. Each calculator shows its formulas and links to the sources behind its benchmarks, with dates, so you can check the method and replace any default with your own numbers.
