A high starting price often means a product is sold to companies and has no small plan, and a score is three letters, not the whole product. Read a tool’s own page before ruling it out.

How is the score on this chart worked out?

It is the average of three of the five grades ToolGPA gives every tool: features, ease of use, and platforms and integrations, with an A worth 4 and an F worth 0. The other two grades, value for money and the free plan, are about price, so they are left out and price gets an axis of its own. 34 of the 35 SEO browser extensions are on the chart; 1 are left off because they are sold for a single payment or publish no price that can be put as dollars a month.

How this chart is made

  • The score is the average of three of a tool’s five grades: features, ease of use, and platforms and integrations. An A is 4 points and an F none. Value for money and the free plan are left out because they are about price, and price has an axis of its own.
  • The price is what paid plans start at, in dollars a month, on the cheapest way of paying the listing names. A yearly price is divided by twelve, and a price in another currency is converted. A price for each person is shown for one person.
  • A tool with no paid plan sits in the band marked Free. A tool with a free plan beside paid ones is placed at its paid price and drawn as a filled dot.
  • The grades are ToolGPA’s own judgement from each vendor’s pages and from public reviews and our own testing, and no vendor can pay for one. How we grade
