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: title and description templates, dynamic snippet variables, a content audit for duplicate and stale content, a stats dashboard, a table of contents block, a bulk SEO editor, automatic conflict detection when another SEO plugin is active, and a one-click migration importer for Yoast, Rank Math, AIOSEO, and SEOPress. Pro layers in AI content and image generation, batch AI suggestions, advanced schema types, custom JSON-LD, internal link analysis, 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 tracking. The only outbound requests are the WordPress update check, IndexNow pings to search engines, and the 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 €69 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.

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 for the core types, title and description templates per content type, dynamic snippet variables, a pixel-accurate search preview, a content audit for duplicate, stale, and thin content, site verification for Google, Bing, Yandex, and Baidu, a table of contents block, 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 generation and AI image generation (your own OpenAI, Anthropic, Gemini, or Mistral API key), batch AI suggestions in the bulk editor, Product/WooCommerce and FAQ schema plus 6 advanced editorial schema types, custom JSON-LD per page, a redirect manager, 404 logging, auto alt text, internal link analysis with orphaned-page detection, and an LLMs.txt generator for €69 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 is an annual subscription Yoast lists at $118.80 per year excluding VAT, and one subscription covers one site. Signocore SEO Pro is €69 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 is €7.99 a month billed yearly, so €95.88 for the first year across unlimited personal sites, renewing at €107.88; client work requires their Business tier at €24.99 a month billed yearly, €299.88 for 100 sites. Signocore SEO Pro is €69 once for unlimited sites with lifetime updates. The AI features differ too: Signocore SEO lets you bring your own API key for OpenAI, Anthropic Claude, Google Gemini, or Mistral, switchable in settings, with no vendor lock-in, and it also generates social and featured images. 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 (for Yoast, Rank Math, and SEOPress) 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 €69 once for unlimited sites you own, with lifetime updates included. It adds AI-generated metadata, titles, and content (using your own OpenAI, Anthropic Claude, Google Gemini, or Mistral API key, switchable in settings), batch AI suggestions for up to 100 posts per run with accept or reject per field, AI image generation for social and featured images (via OpenAI or Gemini), Product/WooCommerce and FAQ schema plus 6 advanced editorial Schema.org types with dedicated meta-fields (Recipe, Event, Course, JobPosting, SoftwareApplication, VideoObject), custom JSON-LD per page, a redirect manager with 301, 302, 307, and 410 (Gone) support, searchable 404 logging with suggested redirect targets and automatic cleanup, automatic alt-text generation, internal link analysis with inbound link counts and orphaned-page detection, and an LLMs.txt generator for AI search engines. Polylang and WPML compatibility ship in the free tier.
How do Pro licenses and updates work?
You activate Pro by entering your license key and email in the plugin settings. There is no activation limit and no per-site licensing, so the same key works on every site you own. Updates arrive automatically through the normal WordPress Updates screen, exactly like any other plugin, and they are never license-gated, so "lifetime updates" means the plugin keeps updating even years later. Licenses are cryptographically signed and validated with a 14-day offline grace period, so a brief outage on our side never locks you out of Pro features.
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.
What's new in the latest release.
v5.8.2 · Last updated Sep 3, 2026 · Tested up to WordPress 7.1 · Requires PHP 8.0+
Changes in version 5.8.2:
- Improved: The notice shown when your server runs an unsupported PHP version now includes the version the site actually runs, so it is easier to spot a hosting panel that has not applied the version you selected.
- Fixed: AI generation now works on sites where WordPress is installed in its own subdirectory or the content folder has been moved.
- Fixed: AI generation no longer fails on shared hosting plans that lock down certain PHP settings.
