Try it freeWhy use free SEO and AI visibility tools?
Search has split in two. People still use Google, but more and more questions are answered directly by AI assistants. Ranking well is no longer enough — your site also needs to be readable by AI crawlers, clearly identifiable as a brand, and written in a way AI engines can quote.
These tools check both sides in minutes. Start with an audit to see what matters most, then use the specialist checkers to fix specific issues. When you want ongoing tracking, a free account keeps your results and history in one dashboard.
Frequently asked questions
What is the difference between SEO, GEO and AEO tools?
SEO tools help you rank in Google and Bing. GEO (Generative Engine Optimization) tools help AI assistants like ChatGPT and Perplexity cite your site. AEO (Answer Engine Optimization) tools help your content get quoted directly as the answer. AeroSearchAI covers all three.
Which free tool should I start with?
Start with the Free SEO + GEO Audit. It scans your site and tells you what to fix first, then points you to the right specialist tool.
Can I put these tools on my own website?
Yes. Several tools can be embedded on your site as free widgets. See the Embed Tools page for details.
