Sharing a category with Frase is what puts a product on this page at all. These 18 seo tools are the closest of the ones that do, ordered by how much of Frase’s categories and tags each one covers and how closely its own description reads like Frase’s — that is an ordering, not a verdict. We have not tested any of them, and there is no score on this page.

This site holds four things about each of these products that are worth comparing before you open any of them, and none of them is an opinion. The pricing model above is the one recorded on the listing — a product marked Contact for pricing will cost you a sales call before it costs you anything else. The open-source column decides whether leaving later is a migration or an export. The shared categories and tags under each entry are how close the overlap with Frase actually is: a tool covering all of Frase’s categories is doing roughly the same job, one sharing a single category may only touch the same part of it — and a tool can be high on this page on the strength of its description alone, which means it describes the same work in the same words rather than that anybody checked it does that work well. Upvotes are votes cast here by people with accounts, and they say what this site’s readers picked, not what is best for you.
What we do not hold is a test. Nobody here has run these products side by side, so the last step is yours: open two of them and give each one the job you actually have.
