What Eba SEO Actually Does
Eba SEO is a free WordPress plugin available on WordPress.org whose entire job is generating valid JSON-LD structured data markup automatically, for posts, pages, and custom post types, without asking you to touch a settings screen. Install it, activate it, and it starts outputting schema code into your page head. There's no wizard, no API key, no "connect your site" step. That's the whole pitch: structured data that just works, with none of the bloat that comes bundled into full SEO suites.
This matters because JSON-LD (the structured data format Google actually recommends over microdata or RDFa) is what powers rich results in search: star ratings, FAQ dropdowns, breadcrumbs, article bylines and publish dates showing up directly in the SERP. Most sites either skip this entirely or get it through a mega-plugin that also wants to rewrite their meta titles, manage redirects, and nag them about premium upgrades.
Who This Is Actually For
- Developers building client sites who already handle titles/meta/sitemaps manually or via a lightweight plugin, and just need schema output solved without pulling in a 10MB SEO suite.
- Niche bloggers and small publishers on shared hosting who want rich result eligibility (article schema, breadcrumbs) without the performance overhead of Yoast or Rank Math running their full module stack.
- Custom post type-heavy sites — recipe sites, directories, portfolio sites — where the built-in schema generation in the big plugins doesn't cleanly map to a custom taxonomy, and adding a schema-only layer is easier than fighting configuration screens.
- Anyone currently running zero structured data because their theme doesn't add it and they never got around to installing an SEO plugin just for that purpose.
What it's not for: sites that need keyword optimization guidance, content scoring, redirect management, or a sitemap generator. Eba SEO doesn't do any of that, on purpose.
Setup, Realistically
Install from the WordPress.org plugin directory or upload the zip via Plugins > Add New. Activate. That's it — there is no settings page to configure in the traditional sense, which is the point, but it also means you have limited control if you want to override specific schema fields on a specific post. Check your output with Google's Rich Results Test after activating to confirm the markup validates for your specific theme and content types; the plugin promises clean output across any theme, but custom post type structures vary enough that it's worth a spot check.
Pricing
Eba SEO is completely free and open source, distributed through the official WordPress.org plugin repository. There is no premium tier, no paid add-on pack, and no account creation required. This is unusual in the SEO plugin space, where free versions typically function as funnels toward a paid upgrade.
How It Stacks Up
| Eba SEO | Yoast SEO | Rank Math | All in One SEO | |
|---|---|---|---|---|
| Price | Free, no paid tier | Free / Premium $99/yr per site | Free / Pro from $59/yr | Free / Pro from $49.60/yr (intro) |
| Core focus | JSON-LD structured data only | Full SEO suite (meta, sitemaps, schema, readability) | Full SEO suite + schema generator + built-in analytics | Full SEO suite + schema + link assistant |
| Setup required | None — works on activation | Onboarding wizard, config screens | Setup wizard, module toggles | Setup wizard, config screens |
| Schema control | Automatic, minimal manual override | Schema editor built into content editor (Premium for full control) | Visual schema builder, multiple schema types per page | Schema generator with templates |
| Best for | Sites that just need clean schema fast | Sites wanting one plugin for everything | Sites wanting granular schema + SEO analytics | Sites already in the AIOSEO/WP ecosystem |
The Honest Tradeoff
If you're running Yoast, Rank Math, or AIOSEO already, you don't need Eba SEO — you'd be duplicating schema output, which can cause validation conflicts in Google's Rich Results Test (two JSON-LD blocks competing for the same @type). This plugin is for the gap case: sites with no SEO plugin, or a minimal one that skips schema, where installing a full suite feels like overkill for one feature.
The risk with any new, minimally-configurable plugin is edge cases — theme conflicts, unusual custom post type structures, or schema types it doesn't yet cover (event schema, product schema with variants, review aggregates). Because it's new and lightweight, it hasn't been battle-tested across the plugin combinations Yoast and Rank Math have survived for a decade. Test your rich result eligibility after activating, and keep an eye on the WordPress.org support forum for the plugin to see what issues other users are reporting as adoption grows.
Bottom Line
Install Eba SEO today if you have zero structured data on your site and want the fastest path to rich-result eligibility without adopting a full SEO plugin. Skip it if you're already on Yoast, Rank Math, or AIOSEO — their schema modules cover the same ground and you'll create conflicts running both.
