Signocore SEO takes care of the technical SEO on a WordPress site: titles and descriptions, social sharing tags, XML sitemaps, robots rules, structured data and breadcrumbs. Free and Pro are the same plugin. A license key switches on the Pro features, so you never reinstall anything to upgrade.
What it does
- Prints the title tag, meta description, canonical URL, robots directives and Open Graph and X (Twitter) tags on every page, from text you write or from templates with placeholders.
- Adds an SEO box to the post editor with a search preview, social previews, keyword checks and a readability estimate. Categories, tags and author profiles get the same fields.
- Builds an XML sitemap index and a robots.txt, applies your noindex rules and can notify search engines through IndexNow when you publish.
- Outputs one connected schema.org graph (JSON-LD) built from your company details.
- Adds breadcrumbs, a reading time shortcode and a Table of Contents block.
- Gives you a Bulk Editor and an SEO Dashboard that point out missing, duplicate, outdated and thin content.
- Imports your existing SEO data from Yoast SEO, Rank Math, All in One SEO and SEOPress.
- Works with WooCommerce, WPML, Polylang and the Genesis framework.

Requirements
Signocore SEO runs on the WordPress and PHP versions listed on the platform support page. The Table of Contents block and the subheading keyword check also need the PHP dom extension; everything else works without it.
