rankmath vs all-in-one-seo
RankMath vs All in One SEO — features, pricing, and which to choose for your WordPress SEO in 2026.
Quick Verdict
RankMath and All in One SEO (AIOSEO) represent the top tier of WordPress SEO plugins, each taking different approaches to helping your site rank better. RankMath launched in 2018 as the feature-packed newcomer, while AIOSEO has been serving WordPress users since 2007 with a focus on reliability and ease of use.
The core difference lies in philosophy: RankMath loads you up with advanced features and granular controls from day one, while AIOSEO prioritizes simplicity and gradually introduces advanced functionality. Both offer solid free versions, but their premium tiers diverge significantly in pricing and target audience.
Feature Comparison
RankMath gives you more features in both free and paid versions. The free tier includes unlimited keyword optimization (AIOSEO limits this to 5), built-in 404 monitoring, redirect manager, and advanced schema markup options. RankMath's Content AI module provides AI-powered writing assistance directly in your WordPress editor, while AIOSEO's AI features focus mainly on title and meta description generation. AIOSEO counters with better local SEO capabilities in its paid version, including location-based schema markup and Google My Business integration. Its WooCommerce SEO module is more comprehensive than RankMath's e-commerce features, with better product schema and category optimization. AIOSEO also offers superior social media integration with automatic Open Graph generation and Pinterest-specific optimizations. Both plugins handle technical SEO fundamentals well—XML sitemaps, breadcrumbs, and basic schema markup. However, RankMath provides more granular control over these features, while AIOSEO focuses on automating them with sensible defaults.
Pricing Comparison
Both start free, but their premium paths differ dramatically. RankMath Pro costs $59/year for unlimited sites, making it incredibly cost-effective for agencies and multi-site users. The Pro version includes Content AI, advanced WooCommerce SEO, and local SEO features. AIOSEO uses per-site pricing: $49.50/year for one site, $99.50 for three sites, and $299.50 for unlimited sites. This makes AIOSEO more expensive for power users but potentially more reasonable for single-site owners who need premium features. AIOSEO's agency plan includes additional support and white-label options that RankMath doesn't offer.
Best For
RankMath works best for SEO professionals, agencies, and WordPress users who want maximum control over their optimization. Its feature density and unlimited site licensing make it ideal for managing multiple client sites. The Content AI integration appeals to content creators who want writing assistance without leaving WordPress. All in One SEO suits WordPress beginners, local businesses, and e-commerce sites better. Its setup wizard and automated optimizations reduce the learning curve, while the local SEO and WooCommerce modules address specific business needs that RankMath handles less comprehensively.
The Verdict
Choose RankMath if you're managing multiple sites or want the most features for your money—its $59 unlimited license is unbeatable value. However, AIOSEO wins for single WordPress sites where you prioritize ease of use, local SEO, or e-commerce optimization over raw feature count. AIOSEO's longer track record and simpler interface make it the safer choice for WordPress newcomers who don't want to be overwhelmed by options.
