There are four serious WordPress SEO plugins and they are much closer than the comparison articles suggest. All four handle the fundamentals competently. None of them will rank your site by themselves.
This covers what they actually do, where they genuinely differ, and how to pick one without spending an afternoon on it. If you want the tactics rather than the tools, our WordPress SEO tips guide covers the work that no plugin can do for you.
What an SEO plugin actually does
WordPress on its own gives you very little control over how search engines see your site. An SEO plugin fills that gap, and the feature list is largely the same whichever you choose:
- Title tags and meta descriptions, per page and via templates, so you are not writing them one at a time forever.
- XML sitemaps, generated and kept current, which is how search engines discover pages efficiently.
- Indexing rules, so tag archives and thin pages stay out of the index rather than competing with your real content.
- Schema markup, the structured data that lets a page appear as a recipe, product or FAQ rather than a plain blue link.
- Canonical tags, which tell search engines which version of a page is the real one.
- Social previews, controlling the image and text when a page is shared.
- Redirects, in most of them, so changing a URL does not strand the old one.
That list is the job. Every plugin below does all of it.
What none of them do
Worth stating plainly, because it is where most of the disappointment with SEO plugins comes from. Installing one changes nothing on its own. It gives you controls; it does not use them.
Specifically, no SEO plugin:
- Writes content anyone wants to read. The green light in the sidebar measures keyword placement, not quality, and optimising for it produces stilted writing.
- Makes your site faster. Speed is set by your hosting, your images and your plugins. An SEO plugin can report a problem it cannot fix.
- Earns links. Still among the strongest ranking signals, and entirely outside what any plugin touches.
- Fixes a site nobody can crawl. If your host is slow or unreliable, that is the constraint.
Google's own starter guide is a better use of an hour than any plugin comparison, including this one. The plugin is plumbing. Useful plumbing, but plumbing.

Talk To Sales →Rank Math
Rank Math is the one that grew fastest, largely because it puts more into the free tier than the others historically did: schema types, redirects, multiple keyword tracking and a setup wizard that makes reasonable choices for you.
Suits: people who want capability without paying, and who do not mind a busier interface.
Watch for: the volume of options. It surfaces a lot of settings, some of which do not matter for most sites, and the scoring system encourages chasing a number that has no relationship to rankings.
Yoast SEO
Yoast is the original and still the most widely installed. Its strength is restraint: fewer options, clearly explained, with documentation that assumes you are not an SEO specialist. The readability analysis is genuinely useful for people who write long sentences.
Suits: beginners, and teams where several people edit content and consistency matters more than configurability.
Watch for: more of the useful extras sit behind the paid tier than with Rank Math. The traffic-light system also invites writing for the plugin rather than the reader, which is a habit worth resisting.
All in One SEO
AIOSEO predates most of the field and rebuilt itself substantially. It leans toward business sites, with local SEO, WooCommerce support and schema handled thoroughly.
Suits: local businesses and stores, where the schema and local features do real work.
Watch for: a fair amount of upsell prompting in the interface, and a free tier narrower than Rank Math’s.
SEOPress
SEOPress is the quiet one. No upsell banners in the admin, a clean interface, and a single flat-priced tier rather than escalating plans. It does the same job with less noise.
Suits: people who find the others cluttered, and agencies running many sites where per-site pricing adds up.
Watch for: a smaller community, so there are fewer tutorials and forum answers when you get stuck.
Compared
| Rank Math | Yoast | AIOSEO | SEOPress | |
|---|---|---|---|---|
| Best for | Most in the free tier | Beginners and teams | Local and ecommerce | A clean, quiet interface |
| Interface | Busy | Simple | Moderate | Clean |
| Redirects included | Free tier | Paid | Paid | Paid |
| Readability analysis | Yes | Strongest | Yes | Yes |
| Upsell in the admin | Some | Some | Noticeable | Minimal |
| Learning material | Good | Best | Good | Thinner |
Tiers and pricing change often, so check each plugin’s own page rather than trusting any comparison table, including this one, on that point.
Which to pick
Honestly: whichever you will actually use. The differences between them are much smaller than the difference between using one properly and installing one and forgetting it.
If you want a decision rather than a discussion:
- New to this? Yoast. The clearest explanations and hardest to misconfigure.
- Want the most without paying? Rank Math.
- Local business or a store? AIOSEO.
- Find the others noisy, or run many sites? SEOPress.
- Already have one installed and configured? Keep it. Switching costs you an afternoon and gains you almost nothing.
What to configure once it is installed
The setup wizard covers the basics. These are the settings that actually change what search engines do with your site, and they are the same in all four plugins even though the menus differ.
Decide what should not be indexed
WordPress generates a lot of pages nobody searched for: tag archives, author archives on a one-author site, date archives, and attachment pages that contain a single image. Left indexed, they compete with your real content and spend crawl budget on nothing.
Set those to noindex unless you have a specific reason to keep them. Category archives are the judgement call, since on some sites they are genuinely useful landing pages and on others they are duplicates of the blog index.
Write title templates, not titles
Every plugin lets you define a pattern for each content type, such as the post title followed by the site name. Getting the templates right once means every future post starts with a sensible title, and you only hand-write the ones that need it.
Keep them short enough not to truncate. Search results cut titles on width rather than character count, so roughly 55 to 60 characters is the practical ceiling before the end disappears.
Turn on the schema that matches what you publish
Structured data is how a page becomes a rich result rather than a plain link. Article schema for posts, Product for shop items, LocalBusiness if you have premises, FAQ for pages with genuine question and answer sections. Marking up an FAQ that does not exist on the page is a guideline violation rather than a shortcut.
Submit the sitemap and then look at it
Your plugin generates a sitemap automatically. Open it and read it. Sites routinely discover their sitemap includes pages they thought were hidden, or excludes an entire post type they care about. Submit it in Search Console afterwards.
Leave the rest alone
The remaining settings mostly do not matter for a typical site, and several can cause harm if changed without understanding them. Breadcrumb configuration, RSS footers and advanced robots directives are all fine on their defaults.
Free versus paid: what you actually give up
All four have a free tier that covers the whole core job. What the paid tiers add is fairly consistent across the field:
| Usually paid | Does a typical site need it? |
|---|---|
| Redirect management | Yes if you change URLs, and a free redirect plugin covers it otherwise |
| Multiple target keywords per page | No. One page competing for one intent is the better habit anyway |
| Internal linking suggestions | Useful on large sites, unnecessary under a hundred pages |
| Advanced schema types | Only if you publish recipes, courses, events or similar |
| Content analysis against competitors | Rarely. It measures word counts, not quality |
| Priority support | Depends how much the site earns you |
The honest summary is that a blog or brochure site can run indefinitely on a free tier without being at a disadvantage. Paying makes sense when redirects become routine, or when the site is commercial enough that support response time is worth money.
Switching between them
If you do move, the order matters, because doing it wrong strips the meta titles and descriptions you have written.
- Back up first. This writes to the database across every post and page.
- Install the new plugin but do not configure it yet.
- Run its importer. All four ship one for the others. This copies your existing titles, descriptions and settings across.
- Check a handful of pages to confirm the data arrived, including one with a custom title you wrote by hand.
- Only then deactivate and delete the old one. Running both produces duplicate meta tags, which is worse than either alone.
Do it on staging if you have one. Our control panel includes staging on every plan, and this is exactly the kind of change it exists for.
The supporting cast
Your SEO plugin does not need company, but three other tools earn their place depending on the site.
- Google Search Console, which is free, is not a plugin, and tells you what your site is actually doing in search. If you install nothing else, install this.
- A redirect manager, if your SEO plugin does not include one in the tier you are on. Changing a URL without redirecting the old one discards every link pointing at it.
- An analytics plugin, if you want the numbers in your dashboard rather than in a separate interface. A convenience, not a requirement.
What is not on that list is a second SEO plugin, an AI content optimiser, or anything promising to automate rankings.
Common mistakes
- Running two SEO plugins. Duplicate meta tags and competing sitemaps. Pick one.
- Chasing the green light. The score measures keyword placement, not quality. Writing for it produces text that reads like it was written for it.
- Leaving everything indexed. Tag archives, author archives and attachment pages competing with your real content is a default worth changing.
- Ignoring the speed warnings. An SEO plugin can tell you the site is slow; it cannot fix it. Our guide to speeding up WordPress covers what does, and how hosting affects rankings covers why the server sets the ceiling.
- Setting it up once and never returning. Search Console will tell you what is broken. Nothing else will.
Pick one of the four, spend twenty minutes on the setup wizard, connect Search Console, and then go and do the work the plugin cannot: write something worth reading, on a site fast enough to read it. Our wider plugin roundup covers the other jobs a site needs filled.
FAQs
For most people, Yoast if you are new to SEO and Rank Math if you want the most capability without paying. AIOSEO suits local businesses and stores, and SEOPress suits anyone who finds the others cluttered. The differences are genuinely small, and using one properly matters far more than which you pick.
No. Two plugins output competing title tags, descriptions and sitemaps, which is worse than running neither. If you are switching, import your settings into the new plugin first, verify a few pages, then deactivate and delete the old one.
Most sites do not. The free tiers cover titles, descriptions, sitemaps, schema and indexing rules, which is the whole job for a typical site. Paid tiers add redirect management, multiple keyword tracking and support, which matter more on larger or commercial sites.
Not on its own. It gives you control over how search engines see your site, but it does not write content, earn links or make your site faster. Think of it as removing an obstacle rather than providing an advantage, since your competitors all have one too.
Back up, install the new plugin without configuring it, run its importer for your old plugin, check several pages including one with a hand-written title, then deactivate and delete the old plugin. All four include importers for the others. Do it on staging if you can.
Depends on the plugin and the tier. Rank Math includes redirects in its free version; the others generally place them in a paid tier. If yours does not, a dedicated redirect plugin fills the gap, and you want one before you start changing URLs rather than after.
The Ranking Factor No Plugin Controls
Speed is measured on your server, not in your SEO settings. FastCow runs on AMD EPYC and NVMe with object caching and a global CDN, so the technical half of your SEO is handled before a plugin is involved.
