Yoast SEO vs All in One SEO

The category's biggest name against its best-value challenger. Yoast is the incumbent — the largest install base, the longest track record, the plugin nobody second-guesses. All in One SEO (AIOSEO) undercuts it on Pro pricing while shipping a modern, WooCommerce-friendly toolkit. Both handle the SEO fundamentals — titles, meta, sitemaps, schema — to the same standard, so the real question is whether you're paying for Yoast's ecosystem or AIOSEO's lower-cost feature set.

Yoast SEO

SEO · Free, Pro from $119 · Since 2010
Full review

Yoast SEO is the most-installed WordPress SEO plugin. Free version covers on-page optimization, sitemaps, breadcrumbs, schema markup, and readability analysis. Premium adds internal linking suggestions, redirect manager, multiple focus keywords, and AI-powered title and meta generation. Acquired by Newfold Digital in 2021, continues to operate as a product unit with sustained engineering investment.

Pros

  • Mature, battle-tested feature set with consistent UI conventions
  • Free version is a complete SEO baseline for most sites
  • Excellent integration with WordPress core changes
  • Strong support and education materials, including SEO academy

Cons

  • Adds noticeable database queries on every page load
  • Aggressive upsell flow in the admin
  • Pricing has crept up significantly since 2020

All in One SEO

SEO · Free, Pro from $49 · Since 2007
Full review

All in One SEO (AIOSEO) is the third major WordPress SEO plugin, originally launched in 2007 by Michael Torbert and acquired by Awesome Motive in 2020. Refreshed under new ownership with modern admin UI, expanded schema support, and tighter integration with the Awesome Motive product family (WPForms, MonsterInsights, OptinMonster).

Pros

  • Mature codebase with 18+ year history
  • Tighter integration with the Awesome Motive product family than Yoast or Rank Math
  • Free tier covers solid on-page SEO baseline
  • Strong WooCommerce-specific SEO features

Cons

  • Awesome Motive product family upsell flow is aggressive across all admin screens
  • Pro tier renewal pricing has crept up since the 2020 acquisition
  • Smaller community discussion than Yoast or Rank Math
The verdict

On core SEO output these are close to a tie — both clear the meta, sitemap, and schema bar every site needs. Choose Yoast for its unmatched ecosystem, tutorial coverage, and beginner-friendly writing analysis. Choose All in One SEO if you know you'll buy a Pro license and want a modern feature set — especially for WooCommerce — at a lower price than Yoast Premium. Whichever you pick, migrate with the built-in importer and never run both at once.

Frequently asked questions

Is All in One SEO better than Yoast?
Neither is decisively better on core SEO — both output clean titles, sitemaps, and schema. All in One SEO's edge is Pro-tier value (a lower entry price and strong WooCommerce SEO); Yoast's edge is its larger install base, deeper ecosystem, and beginner-friendly content analysis. It's a value-versus-ecosystem call.
Which is cheaper, Yoast or All in One SEO?
All in One SEO has the lower entry price to its paid tier, while Yoast Premium sits at the higher end of the category. Compare the specific Pro feature you need, since each vendor tiers its premium features differently — but for getting into a paid plan at the lowest cost, AIOSEO wins.
Can I switch from Yoast to All in One SEO?
Yes. All in One SEO includes an importer that pulls your titles, meta descriptions, and focus keywords from Yoast, and rankings depend on the output — meta tags, sitemaps, schema — not the plugin generating it. Run the importer, verify your metadata transferred, then deactivate Yoast. Never run both at the same time.
