Yoast SEO

Yoast SEO is the most installed WordPress plugin of all time with over 5 million active installations. Founded in 2010 by Joost de Valk, Yoast has shaped SEO awareness among WordPress users like no other tool: the well-known red/yellow/green traffic light display for SEO and readability score is familiar to every WordPress blogger today.

Our Yoast SEO review in 2026 shows: as a WordPress plugin, Yoast is unmatched in user-friendliness and already offers all basic SEO functions in the free version. For professional users, the Premium version is worthwhile with its redirect manager, internal link suggestions, and extended schema options.

Yoast SEO works exclusively with WordPress. Those using a different platform need to turn to alternative SEO tools like Ahrefs or Semrush for website-side SEO optimization.

Real-Time SEO Analysis: The Traffic Light as SEO Tutor

The heart of Yoast is real-time analysis directly in the WordPress editor. While writing or editing an article, Yoast analyzes in real time:

• Focus Keyphrase: The main keyword is checked in the title tag, meta description, H1, first paragraph, alt tags, and URL for correct usage.
• SEO Score: Red (critical issues), Yellow (improvement potential), Green (optimized). Each point explains exactly what the problem is and how to fix it.
• Readability Score: Passive constructions, sentence length, transition words, and Flesch Reading Ease are analyzed — particularly valuable for content quality.

This immediate analysis while writing is the biggest difference from separate SEO audit tools: you fix problems before the article is published.

Schema Markup: Structured Data Without Code

Yoast automatically generates Schema.org markup for articles, pages, authors, and the complete company/person profile. In the Premium version, this extends to custom schema types for specific content formats (How-To, FAQ, Products).

Yoast's schema markup is correctly implemented and is recognized as valid by Google's Structured Data Testing Tool. Rich snippets like star ratings, FAQ accordions, and breadcrumbs are configured directly from Yoast.

XML Sitemaps and Indexing Control

Yoast automatically creates XML sitemaps for all WordPress content — posts, pages, categories, tags, and custom post types. The sitemap is automatically updated with new content and submitted to Google Search Console.

Individual pages, categories, or post types can be specifically excluded from the sitemap and marked as noindex. This is important for tag pages, author pages, or archive pages that should not be indexed.

Redirect Manager (Premium)

In the Premium plan, Yoast includes an integrated redirect manager: when a page is deleted or the URL is changed, Yoast automatically offers to set a 301 redirect. This prevents 404 errors and protects existing link juice.

The redirect manager supports 301, 302, and 410 (Gone) redirects and can also be configured manually. For WordPress sites with frequent URL changes, this is an indispensable feature.

Internal Link Suggestions (Premium)

Yoast Premium analyzes while writing a new article which existing articles your content could thematically link to. These automatic internal link suggestions appear in a sidebar and can be inserted into the text via drag and drop.

Internal links are an important SEO factor — and manually searching your own content library for relevant linking candidates takes time. Yoast's automatic suggestions save this effort considerably.

Pricing and Plans 2026

Premium can be combined with all add-ons. Price is per website.

Who Is Yoast SEO For?

WordPress bloggers and content creators: Yoast Free is the first plugin any new WordPress user should install. The traffic light analysis teaches SEO basics intuitively.

SMBs with WordPress websites: The free version suffices for basic on-page SEO. Premium is worthwhile with more than 20 articles/month due to the redirect manager and link suggestions.

E-commerce operators (WooCommerce): The WooCommerce add-on is recommended for shop operators — product schema significantly improves rich snippet display in Google.

Professional SEO agencies: For agencies, the combination of Semrush or Ahrefs for keyword research and competitor analysis plus Yoast for on-page optimization is the standard workflow.

Yoast SEO vs. Alternatives

Yoast SEO vs. RankMath: RankMath offers more features in the free plan than Yoast Premium — keyword tracking, more schema types, and Google Analytics integration. Yoast has more users (5M+), a more established codebase, and better support. For new projects, RankMath is more attractive price-wise.

Yoast SEO vs. All in One SEO: All in One SEO (AIOSEO) is Yoast's main competitor with a similar feature set. Yoast has the more recognized brand and a stronger content quality focus (readability check). AIOSEO is stronger in some enterprise features.

Yoast SEO vs. Surfer SEO: Surfer SEO is not a WordPress plugin but an on-page optimization platform. Surfer provides deeper content analysis with SERP data. Many professional content teams use Surfer for content creation and Yoast for technical on-page implementation.
