What is Rank Math?
Rank Math launched in 2018 and became one of WordPress's fastest-growing plugins by giving away features rivals charged for. It now powers more than 3 million sites and carries one of the highest ratings on WordPress.org. It's built to be the "Swiss Army knife of SEO" — a single plugin that replaces several.
Even free, Rank Math ships a flexible Schema Generator, up to five focus keywords per post, a 404 monitor and redirection manager, and Google Analytics and Search Console integration with an in-dashboard analytics view. Its modular design lets you enable only the features you use. Pro adds keyword rank tracking, Content AI, advanced schema automation, and WooCommerce SEO.
Rank Math's edge is value and breadth: a lot for free, and a single Pro plan across unlimited personal sites. The trade-off is a denser interface with more toggles to learn.
What is All in One SEO (AIOSEO)?
All in One SEO is one of the oldest names in WordPress SEO — originally released in 2007 and fully rebuilt after Awesome Motive (the team behind WPBeginner, WPForms, and MonsterInsights) acquired it in 2020. The modern AIOSEO powers over 3 million sites and is known for a clean, guided experience.
Its highlights include a friendly setup wizard, TruSEO on-page analysis with an actionable checklist, a next-gen schema generator, a Link Assistant that surfaces internal-linking opportunities and orphaned content, and Search Statistics that pulls Search Console data into WordPress. Redirects, 404 tracking, keyword rank tracking, and WooCommerce SEO arrive on the Pro and Elite tiers.
AIOSEO's strength is a polished, connected experience: if you already run Awesome Motive plugins, it slots in cleanly, and its Link Assistant is genuinely best-in-class for internal linking.
Feature-by-Feature Comparison
Free Plan Features
Rank Math Free
- Up to 5 focus keywords per post
- Advanced Schema Generator
- 404 monitor & redirections
- Analytics + Search Console dashboard
AIOSEO Free
- TruSEO on-page analysis
- Setup wizard & smart defaults
- Sitemaps & basic schema
- Redirects, 404, Link Assistant are paid
Verdict: Rank Math wins the free tier — redirects, 404 monitoring, deeper schema, and multiple focus keywords ship free where AIOSEO gates them behind a paid plan. AIOSEO's free experience is more polished, but Rank Math simply gives you more to work with.
Internal Linking
Rank Math
- In-editor link suggestions & counts
- Content AI link recommendations (Pro)
- No dedicated bulk link-audit tool
AIOSEO Link Assistant

Verdict: AIOSEO wins internal linking. Its Link Assistant is a purpose-built bulk tool that finds orphaned content and suggests links across your whole library — a real advantage on large sites. Rank Math's suggestions are useful but work post-by-post.
Schema & Rich Snippets

- Many schema types free, incl. custom builder
- Schema templates & auto-application (Pro)

AIOSEO

- Content AI writing assistant (Pro)
- WooCommerce SEO (Pro)
AIOSEO
- Awesome Motive suite (WPForms, MonsterInsights)

Verdict: A tie that depends on your stack. Rank Math packs rank tracking and AI into the plugin itself; AIOSEO shines if you already run Awesome Motive tools and want them working together.
Pricing Comparison
The two use different pricing philosophies. Rank Math prices by plan (with unlimited sites in Pro); AIOSEO prices by how many sites you need to cover. That distinction decides which is cheaper for you.
Rank Math Pricing
| Plan | Price | Sites |
|---|---|---|
| Free | $0 | Unlimited |
| Pro | ~$108/yr | Unlimited personal |
| Business | ~$336/yr | Up to 200 client |
| Agency | ~$780/yr | Up to 750 client |
AIOSEO Pricing (year one)
| Plan | Price | Sites |
|---|---|---|
| Free | $0 | Unlimited |
| Basic | ~$50 | 1 |
| Plus | ~$100 | 3 |
| Pro | ~$200 | 10 |
| Elite | ~$300 | 100 |
First-year promo pricing; renewals are roughly double.
Value Analysis
For a single site on the cheapest paid tier, AIOSEO Basic (~$50 first year) undercuts Rank Math Pro — but Basic omits features like the Link Assistant and rank tracking, which only appear on Pro (~$200, 10 sites) and Elite. Rank Math Pro (~$108) hands you the full feature set across unlimited personal sites from the start. Multi-site owners almost always pay less with Rank Math.
Watch for: AIOSEO's renewal roughly doubles the first-year price, and its site caps are strict per tier. Rank Math's Content AI is credit-based. Match the tier to the exact features you need before comparing sticker prices.

Final Verdict
Rank Math and All in One SEO are both modern, well-built plugins, and either handles core SEO cleanly. The decision is less about capability and more about how you value features, price, and workflow.
