A list of 7 “essential” SEO plugins usually skips the part that matters most: several of those plugins do the same job, and running more than one of them at the same time causes real problems — duplicate meta tags, conflicting schema markup, and two plugins fighting over the same settings. Here’s what you actually need: one all-in-one SEO plugin, and two or three tools that do something genuinely different from it.
Step 1: Pick One All-in-One SEO Plugin
Yoast SEO, Rank Math, and AIOSEO (the current name — the old “All in One SEO Pack” branding was dropped years ago) all do the same core job: meta tags, schema markup, sitemaps, and content analysis. Install exactly one.
- Yoast SEO remains the market leader by installs and the most battle-tested option — the safest default if you want the most mature ecosystem and don’t need every feature to be free.
- Rank Math currently has the strongest free tier of the three: 17+ schema types, a built-in redirect manager, and Search Console integration, all without upgrading.
- AIOSEO is worth a look specifically if you’re running WooCommerce, where its commerce-specific SEO features are a genuine differentiator.
There’s no single right answer — pick based on budget and whether you want Rank Math’s free feature set or Yoast’s maturity, not by installing more than one to hedge.
Do You Need a Separate Sitemap Plugin?
No, in almost every case. WordPress has generated basic XML sitemaps natively since version 5.5, and Yoast, Rank Math, and AIOSEO all generate their own, more complete sitemaps as part of the core plugin. Adding “Google XML Sitemaps” or a similar standalone plugin on top of any of these three just means two sitemaps competing to be the one search engines actually use — skip it.
Do You Need a Separate Redirect Manager?
Depends which plugin you picked. Rank Math and AIOSEO both include a redirect manager in the core plugin already. Yoast’s redirect support is more limited, so if you’re on Yoast and manage redirects regularly, the Redirection plugin genuinely fills a gap there rather than duplicating something you already have.
Two Complementary Plugins Worth Adding
These solve problems your all-in-one SEO plugin doesn’t touch, so they’re not redundant with it:
- Broken Link Checker: scans posts, pages, and comments for dead links. None of the three main SEO plugins do this, and broken links hurt both user experience and crawl efficiency.
- Smush (or a similar image optimizer): compresses and resizes images. Page speed is a ranking factor your SEO plugin reports on but doesn’t fix — a separate image optimization plugin is the actual fix.
Once the plugin side is handled, structured data is worth a second look if you’re layering custom schema on top of what your SEO plugin generates — merging multiple JSON-LD schema scripts covers the conflicts that come up there. And for ranking in AI-generated answers specifically, not just classic search results, Generative Engine Optimization for WordPress covers that separate, newer surface.
