The WordPress SEO plugin that doesn't rent itself to you.
A complete alternative to Yoast and Rank Math. AI content analysis, 15 schema types, IndexNow, a bulk SEO editor, and one-click migration from Yoast/Rank Math/AIOSEO/SEOPress. €49 once, unlimited sites, lifetime updates. Or use the free core forever.
What Signocore SEO does.
Signocore SEO is a complete WordPress SEO plugin built as a focused alternative to Yoast and Rank Math. It handles the SEO fundamentals every WordPress site needs (meta tags, XML sitemaps, automatic Schema.org markup, Open Graph, Twitter Cards, breadcrumbs, IndexNow instant indexing) and adds productivity tools you would normally pay for elsewhere: a stats dashboard, a bulk SEO editor, and a one-click migration importer for Yoast, Rank Math, AIOSEO, and SEOPress. Pro layers in AI content analysis, advanced schema types, and a redirect manager.
The plugin is purpose-built for WordPress. It is not a port of a SaaS tool, not a wrapper around an external API, and not a stripped-down version of a different platform. It runs entirely inside your WordPress install with no external accounts, no per-site licensing, and no data leaving your server (apart from optional AI features which use your own API key).
Pricing reflects the same philosophy: the free tier is genuinely useful on its own, and Pro is a one-time €49 with lifetime updates and unlimited sites, not an annual subscription. If you currently pay for Yoast Premium, Rank Math Pro, or All in One SEO Pro on multiple sites, the cost difference becomes obvious within the first year.
Built into WordPress, not bolted on.
Native settings UI, native post-editor sidebar. No iframe dashboards, no external accounts.

Common questions about Signocore SEO.
Is Signocore SEO a free WordPress plugin?
+
Yes. The free version is a complete WordPress SEO plugin with meta tags, XML sitemaps, automatic schema markup (9 types), IndexNow integration, Open Graph and Twitter Card support, breadcrumbs, a stats dashboard with onboarding checklist, a bulk SEO editor, and a one-click migration importer for Yoast, Rank Math, AIOSEO, and SEOPress. Most WordPress sites do not need anything beyond the free tier. Pro adds AI content analysis (your own Claude or OpenAI API key), 6 advanced schema types, a redirect manager, 404 logging, auto alt text, internal link analysis, and an LLMs.txt generator for €49 once.
How does Signocore SEO compare to Yoast SEO?
+
Signocore SEO covers the same SEO fundamentals as Yoast Free (meta tags, sitemaps, schema, social previews, IndexNow) and adds features Yoast keeps in their paid tier: advanced schema types and a redirect manager. Yoast Premium runs around €110/year per site as a subscription ($118.80/year). Signocore SEO Pro is €49 once for unlimited sites with lifetime updates included. No annual renewal, no per-site licensing.
How does Signocore SEO compare to Rank Math?
+
Both Signocore SEO and Rank Math include automatic schema, IndexNow, redirect management, and breadcrumbs in their free or low-priced tier. Rank Math Pro starts at around €88/year (~$96) for unlimited personal sites; client work requires their Business tier at around €275/year ($300) for 100 sites. Signocore SEO Pro is €49 once for unlimited sites with lifetime updates. The AI features differ too: Signocore SEO lets you bring your own API key for either Anthropic Claude or OpenAI, switchable in settings, with no vendor lock-in. Rank Math Content AI is a separate paid add-on with usage limits.
Can I migrate from Yoast, Rank Math, AIOSEO, or SEOPress?
+
Yes. After activation, Signocore SEO detects your existing SEO plugin and prompts you with a one-click import. The importer reads meta titles, descriptions, focus keywords, canonical URLs, robots directives (noindex), Open Graph images, and primary categories. Imports run in batches of 50 items so it handles even very large sites, and your existing Signocore data is never overwritten, so it is safe to run multiple times. Note: redirects from Yoast/Rank Math premium tiers are not auto-imported (Signocore SEO Pro has its own redirect manager with CSV import).
Does Signocore SEO work alongside other SEO plugins?
+
Technically yes, but it is not recommended. Running two SEO plugins simultaneously typically results in duplicate meta tags, conflicting canonical URLs, and competing schema markup that confuses search engines. The right path is to run the built-in migration importer (Yoast, Rank Math, AIOSEO, SEOPress supported), then deactivate the previous plugin.
What does Signocore SEO Pro include and what does it cost?
+
Pro is €49 once for unlimited sites you own, with lifetime updates included. It adds AI-generated metadata and content scoring (using your own Anthropic Claude or OpenAI API key, switchable in settings), 6 advanced Schema.org types with dedicated meta-fields (Recipe, Event, Course, JobPosting, SoftwareApplication, VideoObject), a redirect manager with 301/302 support, 404 logging, automatic alt-text generation, internal link analysis, and an LLMs.txt generator for AI search engines. Polylang and WPML compatibility ship in the free tier.
How do I install Signocore SEO on WordPress?
+
Download the free plugin ZIP from this page, then in WordPress admin go to Plugins → Add New → Upload Plugin, select the ZIP file, and click Install Now. Activate the plugin. The dashboard shows an onboarding checklist. If Yoast, Rank Math, AIOSEO, or SEOPress is detected, you get a one-click prompt to import your existing data; otherwise the checklist walks you through setting a default social image and your company name. No multi-step wizard and no friction. Configure things at your own pace.
