WordPress is a free, open-source content management system that powers a large share of all websites on the internet, popular for a combination of a relatively gentle learning curve, an enormous ecosystem of free and paid themes, and a plugin library covering nearly any functionality a site might need without custom development.
For SEO specifically, that plugin ecosystem is a large part of the draw: dedicated SEO plugins can handle meta tags, sitemap generation, schema markup, and basic technical audits without needing developer involvement for routine tasks. That accessibility is also where WordPress SEO commonly goes wrong, though: a site accumulating dozens of poorly-maintained plugins, a bloated theme carrying far more code than the site actually uses, or unoptimized image uploads can quietly tank page speed even while the content and on-page basics look fine. WordPress's flexibility makes it a genuinely capable platform for SEO when configured carefully, but that same flexibility means SEO performance on WordPress specifically depends heavily on disciplined plugin and theme choices, not just on the platform's own inherent strengths.
