The SEO Framework
The SEO Framework is a free, open-source WordPress plugin that handles on-page SEO — meta tags, XML sitemaps, and basic schema markup — with no ads or upsell nags in the free version. Paid tiers unlock optional extensions like keyword word-form/synonym suggestions and local-business schema, on more sites.
The free core plugin — meta tags, sitemaps, basic schema, explicitly no built-in tracking or third-party integrations — is already close to the weekend-scope WordPress plugin an AI coding tool could build from scratch, and even the paid Focus extension turns out to be a fairly thin wrapper around a third-party dictionary API for keyword word-forms and synonyms, not a proprietary engine.
What you lose building it yourself
- ✕Focus extension's dictionary-API keyword suggestions — word-forms in 7 languages, synonyms in English only
- ✕Local extension's automated local-business schema output
- ✕Articles extension's automated structured data and Google News sitemap support
- ✕Honeypot's six-method spam filter (vendor claims a 99.99% catch rate)
Why people still pay
The core plugin costs nothing either way, so paying buys the Focus extension's dictionary-API keyword suggestions, the Local extension's business-schema automation, and Honeypot's spam filtering — real if modest engineering, worth it mainly for the languages Focus already supports rather than something otherwise unbuildable.
BUILD YOUR OWN · MOSTLY DONE ALREADY
The free plugin already is the weekend-scope build described elsewhere on this site as the DIY baseline for WordPress SEO plugins — meta tags, sitemaps, and basic schema, no AI or paid API required. Matching the paid Focus extension means wiring up a real dictionary API for word-forms and synonyms (in whichever of its seven supported languages you need), and the Local/Articles extensions' schema automation is a few more hours of structured-data work, not a weekend.
StackA WordPress plugin scaffold (PHP) for hooks and the admin UI · native WP functions for meta tag output and sitemap XML · JSON-LD templates for basic schema (Article, Organization) · a free dictionary/thesaurus API (e.g. Datamuse) if replicating Focus's word-form and synonym suggestions.
Build a WordPress plugin in PHP that adds a meta box to the post editor showing: title length with a visual indicator at 60 characters, meta description length at 155 characters, and whether a user-entered focus keyword appears in the title, first paragraph, and URL slug. Register a sitemap.xml rewrite rule that lists all published post and page URLs with their last-modified dates. Output basic Article JSON-LD schema (headline, author, datePublished) in the page head for single posts. Use plain PHP and native WordPress functions only — no external libraries or paid APIs.
QUESTIONS
Is the free version a trial, or usable long-term?
Lifetime free, not a trial — the core plugin (meta tags, sitemaps, basic schema, over 70 on-page checks) has no feature countdown or forced upgrade prompts.
What does the paid 'API requests' quota actually cover?
It's the Focus extension's dictionary lookups for keyword word-forms and synonyms (5,000/month on the Pro plan) — not a Search Console, analytics, or rank-tracking API. The plugin doesn't pull Search Console or GA4 data at all, on any tier.
Why do other WordPress SEO plugin entries on this site name The SEO Framework as their free alternative?
Because it covers the same core job — titles, meta tags, sitemaps, basic schema — for free with no upsell pressure on the core features, which is genuinely rare among WordPress SEO plugins.
