SEO plugins handle meta tags, XML sitemaps, schema markup, and content analysis. Every site should have one, and only one, SEO plugin.
But here’s the thing most guides won’t tell you: a well-built WordPress theme with proper heading hierarchy, semantic HTML, and basic meta tag support already covers a large portion of what SEO plugins claim to do. If your theme outputs clean markup and you write good content, you’re already ahead of most sites running bloated SEO plugins with default settings.
Our general recommendation: If you decide you need an SEO plugin (and most sites benefit from at least the sitemap and schema features), pick one that’s lightweight, doesn’t plaster your dashboard with ads, and gives you real value in its free version. Avoid the trap of thinking a bigger, more popular plugin means better SEO. It doesn’t.
What about Yoast SEO?
Yoast is the most installed SEO plugin (13M+ sites), but that doesn’t make it the best choice. The free version is increasingly limited. Redirect management, 404 monitoring, and internal linking suggestions are all premium-only features that competitors offer for free. The admin experience is cluttered with upsell prompts, and the traffic-light content analysis, while beginner-friendly, can lead to formulaic writing that doesn’t actually help rankings. A well-built theme with proper meta tags does most of what Yoast Free offers. If you’re considering Yoast Premium at $99/year per site, look at what Rank Math and SEOPress give you for free first.
What about All in One SEO (AIOSEO)?
AIOSEO is part of the AwesomeMotive portfolio, which also includes WPBeginner, WPForms, MonsterInsights, and several other plugins that appear prominently in their recommendation lists. The plugin works, but many features are locked behind paid plans, and renewal pricing roughly doubles after the first year. Worth evaluating on its own merits, separate from the visibility it gets through cross-promotion.
