Which one is for you

Pick All in One SEO (AIOSEO) if

  • Fits if you run a WordPress site and want redirects and schema on the lowest paid plan
  • Works for agencies covering many client sites, with up to 100 on Elite

Look elsewhere if

  • Watch out: the prices shown are first-year rates and renewals are about double, so Basic goes from $49.50 to $99
  • Tight if you stay on Lite, as redirects, local SEO and link suggestions all need a paid plan
  • Pricey if you want local SEO, the Link Assistant or rank tracking: Plus is $199, Pro $399 and Elite $599 a year
  • Skip it if you want AI writing in the editor, which needs a separate SEOBoost subscription
  • Not for you if your site isn't on self-hosted WordPress, as there's no standalone app

Pick Site Kit by Google if

  • Fits if you want Search Console and Analytics figures without leaving WordPress
  • Works for agencies setting up Google tools for clients and emailing them stats

Look elsewhere if

  • Too light for SEO on its own, as it edits no titles, meta descriptions, schema or sitemaps
  • Watch out: each admin who wants full access has to connect their own Google account
  • Tight if your site is new, as data can take a few days to appear
  • Skip it if your site isn't live and public on WordPress 5.2 or later with the REST API available

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.
