I ran Rank Math vs Yoast vs All in One Seo on my WordPress sites over several months. One I deleted within a week. One I still use. One I kept paying for way longer than I should have. Here’s the honest version.

Why I ended up testing all three

When I started building this site I did what most people do: I installed the plugin everyone told me to install. That was Yoast. It was fine. It worked. I didn’t think about it much until I started comparing what it could do against what I actually needed it to do, and that’s when things got interesting.

The WordPress SEO plugin space looks simple from the outside — it’s just a few coloured circles and some meta fields, right? But the differences between these tools matter more than most people realise, especially once you’re trying to do anything beyond basic title and description editing. Schema markup, keyword tracking, redirect management, internal linking suggestions, Google Search Console integration — these things vary enormously between plugins, and the pricing gap is just as wide.

So I spent about four months switching between Rank Math, Yoast, and All in One SEO on different sites, paying for the premium versions of each, and keeping notes on what actually changed. Here’s what I found.

Rank Math — the one I kept

Rank Math was the last of the three I tried, and within about two weeks I’d migrated my main site over from Yoast and haven’t looked back. That’s not a dramatic statement. It just does more, for less money, and the interface doesn’t feel like it was designed to make you feel bad about yourself.

The free version of Rank Math is genuinely competitive with Yoast Premium. That’s the part that still surprises me. You get schema markup, redirect manager, 404 monitoring, Google Search Console integration built in, keyword rank tracking, and the ability to optimise for multiple focus keywords. Yoast charges you for most of that. Rank Math gives it to you before you’ve paid a cent.

The content analysis is also smarter in a way that’s hard to articulate but easy to feel when you’re editing. It doesn’t just tell you to use your keyword more — it looks at readability, heading structure, internal and external links, image alt text, and a handful of other signals. The score you see at the top of the editor actually means something. With Yoast I found I was gaming the circles rather than improving the content. With Rank Math I found I was just writing better.

Where Rank Math Pro earns its price is the rank tracking and the advanced schema types. If you’re running a recipe site, a local business, a product review blog, or anything where structured data matters, the schema module alone is worth the subscription.

If I had one complaint it’s that the onboarding wizard can feel like a lot on day one. Yoast gets you to a working state faster. Rank Math gets you to a better state, just not as quickly.

Yoast SEO — the one I stayed on too long

Yoast was the default for so long that it basically became synonymous with WordPress SEO. And look, it’s not bad. It works. It’s well documented, widely supported, and your developer probably knows how to troubleshoot it. There’s genuine value in that.

But I stayed on Yoast Premium for about eight months before I finally moved, and looking back I’m not sure what I was waiting for. Comfort is expensive when you’re paying around $99 a year for features that competitors give away for free.

The readability analysis — those famous green circles — is fine for beginners. But it flags things in a way that doesn’t always improve your content. The signal starts to feel noisy after a while. The schema implementation is where I found it most limiting. Rank Math handles most of that in the free tier.

The one area where Yoast still holds up is onboarding. For teams where different people are writing and publishing without much SEO knowledge, the familiar interface counts for something.

All in One SEO — the one I deleted fastest

All in One SEO (AIOSEO) is a legitimate product with a large user base. I deleted it within about a week on the site I tested it on, but that’s partly a fit issue, not purely a quality issue.

The interface felt cluttered. Lots of toggles, lots of panels, not a lot of clarity about which ones actually matter. I found myself opening the settings, getting overwhelmed, closing them, and opening them again. The free version is also quite limited — more so than either Yoast Free or Rank Math Free.

Where AIOSEO has a genuine edge is WooCommerce integration. Large e-commerce stores with hundreds of products should give it a proper look before deciding.

Side-by-side comparison

Here’s how the three tools stack up on the features that actually matter for most WordPress site owners.

The pattern is clear. Rank Math Free does things the other two charge you for. Rank Math Pro at ~$84/year still undercuts Yoast Premium while offering more. The only clear exception is WooCommerce, where AIOSEO’s Pro tier does genuinely strong work.

Who each tool is actually for

My final recommendation

If you’re setting up a new WordPress site today: install Rank Math Free, run it for a week, and see if it covers your needs. For most people running content sites, blogs, or small business websites, the free version is enough to get started properly.

If you’re doing affiliate content, writing reviews, running a local business, or managing more than a handful of sites, upgrade to Rank Math Pro. At around $84 a year it’s not a decision you’ll regret or even think about again.

If you’re currently on Yoast Premium and wondering whether to switch — yes, you should. The migration is straightforward, Rank Math has a built-in Yoast importer, and you’ll end up with more features at lower cost.

The only scenario where I’d steer you differently is a large WooCommerce store with hundreds of products. In that case, AIOSEO Pro is worth evaluating properly before you commit.

Prices and features were accurate at the time of testing. Always check the vendor’s current pricing page before purchasing.
