Which one is for you
Pick FluidSEO if
- Fits if you design in Webflow and run SEO checks before a client site launches
- Works for sites with lots of CMS images still missing alt text
Look elsewhere if
- Skip it if your site isn't on Webflow, as it only runs inside the Webflow Designer
- Watch out: the pricing page doesn't say what the free plan covers, or whether monthly prices are billed monthly or yearly
- Tight if you pick Basic, since the $39 buys 14 days of access and then stops
- Too light for rank tracking, keyword research or schema beyond Article, Organization and Breadcrumb
Pick Semflow if
- Fits if you build client sites in Webflow or Framer and handle their SEO
- Works for agencies that want one subscription for unlimited sites
Look elsewhere if
- Not for you if you want a free plan, as there's only a 7-day trial
- Pricey if you need keyword research, rank tracking or schema, which need Pro at $29 a month or $19 yearly
- Watch out: rank tracking is shown week over week, not daily

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.
