Pick AI SEO Copilot if

- Works for freelancers who want a free SEO check for client sites
Look elsewhere if
- Skip it if your site isn't on Webflow, as it only runs inside the Webflow Designer
- Too light for site-wide audits, since each check covers one page and one keyword
- Watch out: a page must be published to staging or production before it can be checked
- Not for you if you want a support contract, as help is by email, GitHub and a feature board

- Too light for rank tracking, keyword research or schema beyond Article, Organization and Breadcrumb

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
