Rank Math vs AIOSEO Which WordPress SEO plugin should you install in 2026?
A side-by-side look at Rank Math and AIOSEO, built only from what each vendor publishes on its own site. Pricing, licensing and feature availability are quoted as documented — where a vendor does not state something, we say so rather than guess.
Rank Math 
AIOSEO The quick verdict
Both are capable. They optimise for different things.
Every plugin here covers the SEO basics — titles, sitemaps, schema and analysis. The differences that actually decide it are licensing, how much you pay in year two, and whether AI is bundled or sold separately.
Rank Math Feature-dense
Rank Math packs the most modules into the entry plan — its cheapest paid tier covers unlimited personal sites rather than one.
- Its PRO plan covers unlimited personal websites, not a single domain
- Rank tracking is built in, from 500 to 50,000 keywords by tier
- AI Link Genius and automated keyword linking are included
- 30-day money-back guarantee, the longest here alongside Yoast
AIOSEO All-round toolkit
AIOSEO bundles the broadest set of on-page tooling, and is the only one here whose AI optimisation is included on every plan, free tier included.
- Optimize with AI is included on every plan, including the free version
- TruSEO analysis, Link Assistant and Redirection Manager in one plugin
- Deep page-builder coverage for Elementor, Divi and others
- Translated into 54+ languages

Pricing
What you actually pay in year two
Entry pricing reads as Rank Math at €7.99/mo, AIOSEO at $99. Those are not like-for-like: Rank Math prices per month in euros billed annually, while the others quote a yearly figure in dollars, and licences cover different numbers of sites.
The renewal is where they diverge. SEOPress states on its pricing page that it renews at the same price. AIOSEO's headline figures are promotional first-year rates against a higher list price, and Rank Math documents a renewal at its pre-discount rate. Yoast does not publish a renewal policy.
No clear edge: prices are quoted in different currencies
Licensing
How many sites one licence covers
Rank Math's cheapest paid tier covers unlimited personal websites, with client sites excluded until the Business tier at 100 sites. Everyone else starts at a single site: Yoast covers one site or domain, AIOSEO's Basic covers one, SEOPress PRO starts at one and moves to five for $59/year.
If you run a handful of your own sites, the licence maths matters more than the sticker price — a $49 single-site licence bought four times costs more than one unlimited plan.
Edge: Rank Math for multi-site owners
AI
Bundled AI versus a second subscription
Rank Math: Content AI sold as its own plan. AIOSEO: No — included on every plan.
That distinction is easy to miss when comparing headline prices. AIOSEO is the only one of the four that documents its AI optimisation as included on every plan, free tier included. SEOPress takes the opposite approach — you connect your own provider key, from OpenAI, Claude, Gemini, DeepSeek or Mistral, and buy credits separately if you want its hosted option.
Edge: AIOSEO for bundled AI

Decision guide
Who should choose which
Choose Rank Math if…
- You run several of your own sites and want them all on one licence
- Built-in rank tracking matters more to you than a separate tool
- You want the widest module list at the lowest entry tier
- Agency licensing for 100 or 500 client sites is on your roadmap
Choose AIOSEO if…
- You want AI optimisation without a second subscription on top
- Internal-link suggestions and redirect management should live in the SEO plugin
- You build in page builders and need SEO controls inside them
- A 100-site Elite licence fits how you work with clients
There is no single winner here. These are quoted in different currencies and billing cycles, so compare the annual total for the number of sites you actually run — Rank Math covers the most sites per licence, and the right pick is whichever one matches how many sites you run and whether you want AI included or bought separately.

Picking the plugin is the easy part
A plugin sets your titles and schema correctly. It will not tell you which pages deserve the effort. If you want a content and technical plan built around where your rankings actually are, we can put one together.
FAQ
Frequently asked questions
Which of Rank Math and AIOSEO has the best free version?
All of them ship a free version. Yoast describes its free tier as "free forever" with no paywalled essentials and includes analysis, sitemaps and schema. AIOSEO's free Lite version is the only one of the four that includes its AI optimisation feature. Rank Math and SEOPress both offer free plans covering core SEO modules.
Which one is cheapest?
Among the plans quoted in dollars per year, AIOSEO is lowest at $99. Rank Math is priced in euros per month billed annually, so it is not directly comparable without a currency conversion — but its entry plan covers unlimited personal sites rather than one, which can make it cheaper per site.
Do any of them include keyword rank tracking?
Rank Math includes rank tracking in its paid plans, from 500 keywords on PRO up to 50,000 on Agency. AIOSEO offers a Keyword Rank Tracker alongside its Search Statistics module.
Do I need a second subscription for the AI features?
Rank Math: Content AI sold as its own plan. AIOSEO: No — included on every plan. If AI matters to your workflow, compare the combined cost rather than the plugin licence alone.
Can I switch between these plugins without losing my settings?
Yoast is the only one of the four that documents built-in migration tools for importing from another SEO plugin. The others do not publish a migration path on the pages reviewed here, so check their documentation before you switch.
Which should an agency managing client sites pick?
Rank Math sells explicit client-site licensing at 100 sites (Business) and 500 sites (Agency). AIOSEO tops out at 100 sites on Elite with priority support.
