Frequently Asked Questions
Can seokit replace Yoast for WordPress users?
seokit can generate meta tags, schema markup, and robots.txt for WordPress sites, but it does not auto-inject them into WordPress like Yoast does. WordPress users may want to use both — Yoast for auto-integration and seokit for advanced schema and robots.txt generation.
Is Yoast SEO free?
Yoast has a free plugin with basic features. The premium version ($99/year per site) adds redirect management, internal linking suggestions, and advanced schema controls.
What CMS does seokit support?
seokit works with any website. It generates code you copy into your site, regardless of whether you use WordPress, Astro, Next.js, Shopify, Hugo, or plain HTML.
Which is better for schema markup?
seokit's schema generator supports 15+ schema types with full JSON-LD output. Yoast auto-generates basic schema for WordPress content but offers less manual control over complex schema types.
