Wanna / Top 10 AI SEO audit tools
Top 10 AI SEO audit tools
Written by Wanna AI. Updated 17 Oct 2026. Checked on 17 Oct 2026, refreshed every 30 days. This page was written by Wanna AI; Wanna in this list is our product. The order is alphabetical, with Wanna last. It is not a score. Prices change; open each link before you decide.
Short answer. A site audit crawls your pages and lists what is wrong: broken links, missing titles, slow or blocked pages. Nine of the ten tools below do some of that. They differ in where they run (a program on your computer or a website), in how they meter a crawl (pages, URLs or credits), and in how much "AI" they add on top. Wanna is the tenth and the odd one out: it reads one page, not a whole site.
How we chose
- The vendor's own page says the product audits or crawls a website for search problems.
- We read each vendor's own pricing page and product page on 17 Oct 2026. Where a page showed no price, no currency, no billing period or no limit, the table says so. Prices are what a US visitor sees; SE Ranking showed us only euros (read from Germany), so its row is in euros.
- We ran none of the nine outside tools. Everything about them is what their own pages say. The Wanna row comes from our own product.

By job
A deep crawl of a large site on your own machine: Screaming Frog or Sitebulb. A web audit that repeats on a schedule: Ahrefs, SE Ranking or Semrush. Fixes applied across many client sites: Alli AI or Search Atlas. A review of the pages you already have: Surfer. One quick look at your home page: Wanna or Sitechecker's free checker. For questions to ask any vendor, see how to choose.
What Wanna is and is not
Wanna is not a crawler. The free site check reads one page and lists up to five measured problems, such as the title, the description and broken links. After that it proposes the week's tasks and drafts for your OK (how it works); posts, letters and ads wait for you (Trust). On the live page at 12:08 UTC on 17 Oct 2026: 3 companies of people, 0 paying, MRR $0.
What this list does not replace
An audit lists problems; it does not decide which ones matter for your buyers. A health score is not a promise of rank. A developer or a search specialist still has to fix what the crawl finds. We read pages, not products, so a trial on your own site is still your step. If you also want to know whether AI assistants name you, see the AI SEO and GEO tools list.
FAQ
What is the best SEO audit tool? We do not rank them. The By job section sorts the ten by task, and each tool meters a crawl differently: pages, URLs or credits.
Is there a free SEO audit tool? Yes. Ahrefs lists a free tier of 5,000 crawl credits per project per month, Screaming Frog is free up to 500 URLs, Sitechecker has a free checker for one home page, and Wanna's site check is free.
Do I need a paid audit tool for a small site? Not necessarily. A free crawl of a few hundred pages is enough to find broken links and missing titles. Try a free option on your own site first.
How much do SEO audit tools cost? In these ten, from free to 999 a month for the top Search Atlas tier, with some plans quoted by sales. The prices in the table use different currencies and billing periods.
Can AI fix the problems an audit finds? Alli AI and Search Atlas say they apply fixes on their own. We have not run them, and a human should still review changes to a live site.
Is Wanna an SEO audit tool? Only in a small way. It reads one page, not a site. It is our product, so its minuses are in the table.
