STS SEO

Description

STS SEO adds the search and sharing details WordPress does not provide on its own, and leaves everything else to WordPress.

What it adds

• An optional SEO title for each post and page. WordPress still prints the one <title> element; STS SEO only supplies its text.
• An optional search description. When it is empty, the manual excerpt or a short summary of the content is used.
• Open Graph and Twitter Card tags, with one social image chosen from the post’s own selection, its featured image or a site-wide default.
• A canonical link for the posts page (WordPress already handles single posts and pages).
• One optional Organization, LocalBusiness or Restaurant entity in JSON-LD, built only from what you enter in Settings → STS SEO.

What it leaves to WordPress

The title element, robots directives, canonical links on single content, XML sitemaps, feeds and search-engine visibility. STS SEO never changes the “Discourage search engines” setting.

Works alongside other plugins

• When a full SEO plugin is active (Yoast SEO, Rank Math, All in One SEO, SEOPress, The SEO Framework or Slim SEO), STS SEO turns all of its front-end output off. Your STS SEO fields are kept.
• With Jetpack, ownership is decided feature by feature. STS SEO provides the social tags on posts, pages and the posts page and turns Jetpack’s Open Graph tags off there, using Jetpack’s own filter. With Jetpack’s SEO Tools module active, titles and descriptions are left to Jetpack.

Privacy

STS SEO makes no external requests, loads nothing from other servers, sets no cookies and collects no data. It adds no JavaScript or CSS to the public site. Its fields are not exposed through the public REST API.

Developer hooks

All filters are optional.

• sts_seo_enabled (bool) – return false to turn off all front-end output.
• sts_seo_conflicts (string[]) – names of active full SEO plugins; any name turns all output off.
• sts_seo_feature_owner (string $owner, string $feature) – return a plugin name to leave one feature (title, description, social, posts_canonical, schema) to that plugin.
• sts_seo_jetpack_social (bool) – return false to keep Jetpack’s social tags.
• sts_seo_title (string $title, int $post_id) – the title override for a public post or page.
• sts_seo_description (string $description, int $post_id) – the description for a public post or page.
• sts_seo_social_image_id (int $attachment_id, int $post_id) – the chosen social image; invalid IDs give no image.
• sts_seo_posts_canonical_enabled (bool) – return false to skip the posts-page canonical link.
• sts_seo_schema_enabled (bool) – return false to skip the JSON-LD entity.
• sts_seo_schema_entity (array $data, array $settings) – the complete entity; return a non-array to skip it.

Values returned by the title and description filters are normalized to plain text again before output.
