AIOSEO Stats

When I started exploring WordPress SEO plugins, I wanted something comprehensive, beginner-friendly, and reliable. That’s when I came across All in One SEO (AIOSEO) — one of the oldest and most trusted SEO plugins for WordPress.
AIOSEO was first launched in 2007 and now powers over 3 million websites worldwide. The free version offers all the essential SEO tools you need to optimize your WordPress site — including XML sitemaps, meta title and description settings, basic schema markup, and on-page SEO analysis.
I especially like how its setup wizard walks you through the entire process, helping you configure your site’s SEO in just a few minutes — perfect for beginners. The plugin also makes it easy to manage social media meta tags, connect to Google Search Console, and handle basic WooCommerce SEO settings for online stores.
Features like redirect management, 404 error tracking, internal linking suggestions, and advanced schema controls are available in the Pro version, but even with the free plan, you can efficiently optimize your pages and posts for search engines.
Whether you’re running a blog, business website, or small eCommerce store, AIOSEO Free gives you a strong SEO foundation — with the option to upgrade anytime for more advanced features.

- Import/Export & Migration Tools: I can easily migrate SEO data from other plugins like Yoast, Rank Math, or SEOPress.
- Advanced XML Sitemap: Supports standard, Video, News, RSS, and HTML sitemaps.
Drawbacks
- Performance Impact: On low-end hosting, the plugin can slightly slow down the admin area when multiple modules are active.
- No Built-in Redirection in Free Plan: You’ll need to upgrade or use a separate plugin to manage redirects.
Final Verdicts
After trying all three SEO plugins, I personally find Rank Math SEO the most feature-rich and beginner-friendly option. It’s the only free plugin among the three that includes redirection management, something usually locked behind premium plans in other tools.
While Yoast SEO and All in One SEO are great choices for solid on-page optimization, Rank Math gives me more control and flexibility — especially for handling redirects, schema, and advanced content optimization — without spending a single rupee.
If you’re looking for a powerful all-round SEO plugin with generous free features, Rank Math SEO is my top recommendation.
