Yoast SEO is the most successful WordPress plugin of any kind. It is also a plugin — not a content engine, not a research tool, not a publishing service. Based on product docs, public reviews, and hands-on product exploration.
Install Yoast Free if you run a WordPress site and want the basics covered — sitemaps, meta tags, focus-keyword scoring, schema. Buy Yoast Premium if you publish weekly and want internal linking suggestions + multiple keywords per post. Skip Yoast Premium if you publish monthly or use RankMath happily. None of it writes content. If you want done-for-you SEO articles published to WordPress, theStacc handles 30 articles per month from $99/mo.

theStacc vs Yoast SEO — where we are honestly better (and worse)
| Feature | Yoast SEO | theStacc |
|---|---|---|
| Starting price | Free (or $99/yr Premium) | $99/mo |
| WordPress on-page optimisation | Best-in-class | Built-in for theStacc articles |
| Schema markup generator | Comprehensive | Auto-applied |
| Keyword research / SERP analysis | None (Semrush integration only) | Built into every article |
| Articles written for you | No — you write the content | 30 / month |
| Auto-publishes to your CMS | Plugin only — you click Publish | Scheduled auto-publishing |
| Google Business Profile posts | Not included (Local add-on is on-site only) | 30 GBP posts / month |
| Social media posts | Only controls how shared links appear | 30 posts / month |
| Off-WordPress (Webflow, Ghost) | WordPress only | All major CMSes |
| Real monthly cost (plugin + writers + research) | $2,500–$7,800 | $99 flat |
Where Yoast wins: if you have a WordPress site, you should install it (or RankMath). It is the right tool for on-page WordPress configuration. Where theStacc wins: if your job is producing the content Yoast scores, not just scoring it.
What is Yoast SEO?
Yoast SEO is a WordPress plugin that handles on-page SEO inside the WordPress editor. Founded by Joost de Valk in 2010, it now powers 12 million+ WordPress sites and maintains a 4.8/5 rating across 27,500+ WordPress.org reviews. Yoast was acquired by Newfold Digital in 2021.
The plugin does six core things:
- Focus keyword scoring — the iconic green/orange/red traffic light system
- Readability analysis — Flesch reading ease, passive voice, sentence length, transition words
- Schema.org markup — Article, FAQ, HowTo, Local Business, Product schema
- XML sitemaps — auto-generated and submitted to Google
- Meta tag control — title, description, OG image, canonical, robots
- Breadcrumbs — output via shortcode or theme integration
What Yoast is not: a content writer, a keyword research tool, a backlink analyser, or a tool that works outside WordPress.
Joost de Valk founded Yoast in 2010. The plugin was acquired by Newfold Digital (parent of Bluehost and HostGator) in 2021. Joost remains involved as Chief Product Officer. The free plugin has been continuously developed for 16 years — making it one of the longest-lived SEO products of any kind.
Yoast SEO features — the full 2026 walkthrough
1. Focus keyword scoring (the traffic light)
Enter a focus keyword. Yoast scores your post on 20+ on-page signals: keyword in title, keyword in URL, keyword density, keyword in subheadings, keyword in image alt text, internal links, outbound links, meta description, and more. The traffic light (green / orange / red) is the most copied UI in SEO software history.
2. Readability analysis
Calculates Flesch reading ease, flags overlong sentences, marks passive-voice instances, highlights paragraphs that need transition words, and warns about repeated sentence beginnings. Best-in-class beginner education for new writers — the warnings teach you what to fix.
3. Schema.org markup
Auto-generates Article schema on every post. Supports FAQ, HowTo, and breadcrumb blocks in the Gutenberg editor. Premium adds Local Business schema, Person schema, and more comprehensive Article variants. Validation against Google's Rich Results test is consistently clean.
4. XML sitemaps + breadcrumbs
Auto-generated sitemap index split by post type. Auto-pings Google when content changes. Breadcrumb output works with most themes via shortcode or template tag.
5. Premium features ($99/yr)
- Internal linking suggestions — recommends related posts to link to as you write
- Multiple focus keywords — score one post against up to 5 keywords
- Redirect manager — handle 301s, 302s without editing .htaccess

Local SEO (Google Business profile sync, store locator schema). Video SEO (video sitemap, OpenGraph for video). News SEO (Google News sitemap). WooCommerce SEO (product schema, brand archives). Premium Plus bundles all add-ons for $229/year.

What it actually costs to run SEO with Yoast as the on-page layer

Performance benchmarks — Yoast vs RankMath vs AIOSEO
WordPress SEO plugin market share
"Yoast taught me on-page SEO over a decade. The traffic light was the first feedback loop that made my writing measurably better. Then I learned the real game is content production — and Yoast doesn't do that." — WordPress agency founder, 11 years (anonymised)
Who Yoast SEO is best for — and who should skip
Strong fit
- Any WordPress site that needs on-page SEO basics
- WordPress agencies who want one consistent plugin per client
- Content teams already comfortable with the Yoast UI
- News and publishing sites (Yoast News add-on)
- WooCommerce stores needing product schema
Probably the wrong call
- Anyone on Webflow, Ghost, Shopify, or Squarespace
- New WordPress sites where RankMath Free covers more
- Users who want keyword research inside the plugin
- Local service businesses wanting GBP posting (Yoast Local is on-site only)
- Anyone hoping the plugin will produce content

Is Yoast SEO worth it in 2026? Final verdict
For every WordPress site: install something. Yoast Free or RankMath Free covers 80% of on-page SEO. Not having an SEO plugin in 2026 is leaving rankings on the table.
For established WordPress sites publishing weekly: Yoast Premium is worth it. Internal linking suggestions and multiple focus keywords genuinely save time. $99/yr is rounding error in a real content budget.
For local service businesses: Local add-on is overpriced. The $79/yr Local add-on adds Local Business schema and store-locator features but does not post to GBP. Pair Yoast with a platform that handles GBP, or use theStacc Bundle which includes both.
For new sites: try RankMath Free first. It is genuinely more generous on the free tier. If the UX bothers you, switch to Yoast — both plugins import each other's settings.

Frequently asked questions
Yoast SEO is the most installed WordPress SEO plugin in history, with 12 million+ active installs and a 4.8/5 WordPress.org rating. It handles on-page SEO inside the WordPress editor — focus-keyword scoring, readability analysis, schema markup, XML sitemaps, and meta tag control.
Free version covers the basics. Premium is $99/yr per site. Local SEO, Video SEO, News SEO, and WooCommerce SEO each cost $79/yr. Premium Plus bundles all add-ons for $229/yr.
RankMath Free includes more features than Yoast Free (multiple keywords, schema templates, redirects). Yoast Premium has cleaner UX, better support, and stronger documentation. For new sites: RankMath Free. For established sites: Yoast Premium.
No. Yoast optimises content you have already written. It scores your draft against a focus keyword, suggests readability improvements, generates schema, and controls meta tags. It does not generate articles, do keyword research, or analyse competitor SERPs.
For established WordPress sites publishing weekly: yes — internal linking suggestions and multiple focus keywords are genuine workflow wins. For new sites or low publishing frequency: Yoast Free is enough. For non-WordPress sites: irrelevant.
Yoast Premium integrates with Semrush via the editor — you see related keyword suggestions inline. It does not have its own keyword database. For serious research you still need Ahrefs, Semrush, or Ubersuggest separately.
RankMath ($59/year Pro) for more free features. All in One SEO ($49/year) for budget. SEOPress (€39/year) for a clean European alternative. For done-for-you content with publishing, theStacc ($99/mo) handles 30 articles per month directly to WordPress.
Yoast adds modest overhead — typical impact is 50–150ms TTFB on a healthy site. The 21.0+ refactor improved performance substantially. RankMath benchmarks slightly faster on most setups but the difference is rarely user-visible.
No. Yoast Local SEO ($79/yr) adds Local Business schema, store-locator features, and on-site location pages — but does not post to GBP, manage citations, or monitor reviews. For real local SEO automation you need a dedicated tool.
Only if RankMath Free covers a Premium-only Yoast feature you actually need (multiple keywords, redirects, schema templates). Both plugins offer one-click import of each other's settings, so the switch is low-risk if the value is real.
