原文外掛簡介
Visibility is the SEO essentials in one light plugin: meta tags, canonical URLs, Open Graph, schema, robots rules, redirects, a robots.txt editor, llms.txt, Markdown for AI agents and control of the native XML sitemap, in about 505 KB.
Free, all of it. No Pro version, no upsell banners, no account.
No tracking. Nothing phones home.
Light. Built on WordPress core APIs, with no database tables of its own and no cron jobs.
Easy to switch to. One-click import from Yoast SEO, Rank Math, All in One SEO, SEOPress, The SEO Framework, Slim SEO and SureRank.
Ready for AI search (AEO and GEO). Clean metadata, llms.txt and a Markdown version of every page, for ChatGPT, Perplexity, Gemini and other AI assistants to read and cite.
Four modules, switch on only what you need
Discover: meta tags, schema and AI discovery
Meta title and meta description, with templates and per-post and per-term overrides.
Canonical URLs on entries and on every listing.
Open Graph and Twitter Cards.
JSON-LD schema: Article, BreadcrumbList, Person, ProfilePage, FAQPage and Site Identity (Organization, LocalBusiness or Person). Choose the type per content type, or None to leave it to another plugin.
Author details (job title, topics and credentials), shown with the Author details block or the [visibility_author_details] shortcode. Each author can pick a page as their profile page.
AI discovery: llms.txt, llms-full.txt, a Markdown version of each page and a robots.txt editor with AI crawler rules.
Respect nosnippet: content set to nosnippet stays out of the llms.txt summaries, llms-full.txt, Markdown and FAQPage.
A filter for content that has not been updated in a while.
Indexing: noindex and clean URLs
noindex, nofollow, noimageindex and nosnippet, in bulk by content type and taxonomy or one by one.
Rules for search results, 404, date, paginated, attachment and author archives, and for RSS feeds.
Keep part of a page out of Google’s snippets with data-nosnippet, from the block editor or the classic editor.
Remove the base of any taxonomy, choose a WooCommerce product URL structure and redirect attachment pages to their parent, with 301 redirects from the old URLs.
Quick Edit, bulk actions and a Visibility column on your post and term lists.
Sitemaps: control of the native XML sitemap
Works on the sitemap WordPress already generates, instead of adding a second one.
Exclude post types, taxonomies, users, posts and terms. Noindexed content stays out automatically, and so does content whose canonical URL points to another address.
Add URLs of pages served outside WordPress.
lastmod dates, and 301 redirects from the sitemap URLs of your previous SEO plugin.
Keeps /wp-sitemap.xml answering 200 on a site with no blog posts, which older WordPress versions got wrong.
Redirects: 301, 302, 307 and 410
Managed from the admin: no .htaccess editing, no custom table, no 404 log.
CSV import and export.
A suggested redirect when you delete a post.
Take over the redirects WordPress creates when a slug changes.
Redirect chains answered in one hop, and loops refused.
Good to know
Per-post controls live in the Block Editor sidebar and in a Classic Editor meta box, with a live preview of your Google result, your social card and an AI answer.
The Tools tab groups the importers and exports your configuration as JSON for another site.
AI agents can read and edit the SEO of your posts and terms through the WordPress Abilities API, with the WordPress MCP Adapter, Novamira or any other client. EMCP Tools exposes the same fields over MCP while you edit a page in Elementor.
Multilingual: works with WPML and Polylang, with a folder or a domain per language.
Visibility replaces a full SEO plugin instead of running next to one, and warns you if another one is active.
Perfect companions
Visibility works on its own. These plugins pair well with it:
VigIA: see which AI crawlers visit your site. Both plugins share the Site Identity schema without duplicating it.
Share Buttons & AI-powered Summaries: share buttons for social networks and AI assistants.
AI Content Signals: tell AI systems how they may use your content (training, search or both) through robots.txt.
Vigilante: all-in-one WordPress security: firewall, login protection, security headers, 2FA and file integrity monitoring.
External services
This plugin connects to Gravatar (operated by Automattic Inc.) to check whether an author has a public avatar, so it can be used in Open Graph (og:image) and in Person schema (image).
What is sent: an MD5 hash of the author email, in a HEAD request to https://www.gravatar.com/avatar/{hash}?d=404. The email address itself is never sent.
When: on a single post or page with Open Graph on and no other image available (social image, featured image, WooCommerce gallery image or image in the content), and on an author archive with Person schema on.
How often: the result is cached for 24 hours, so later page loads do not contact Gravatar again.
It is the same lookup WordPress uses for comment avatars. Gravatar’s privacy policy: https://automattic.com/privacy/
Performance and security
“Lightweight” should be a measurement, not a slogan. These are the real numbers for this release, refreshed on every update.
Footprint (3.0.0)
Download size: about 505 KB zipped.
Codebase: 51 PHP files, roughly 39,700 lines of PHP, plus 3,400 lines of JavaScript and 2,600 of CSS, loaded only where they are used.
On a page view: 26 PHP files, and no database query added to a post, a page or the home page of a default install.
No custom database tables. One option for the settings and native WordPress meta for per-post, per-term and per-author values.
No cron jobs.
No external HTTP calls, except the cached Gravatar check described above.
Built on WordPress core APIs (wp_robots, wp_sitemaps_*, register_post_meta, get_canonical_url, the Block Editor).
Measured against other SEO plugins
The same clean WordPress, the same theme and the same 30 posts, with one SEO plugin active at a time on its default settings. Each figure is what that plugin adds to WordPress with no SEO plugin. Measured in October 2026 on the current release of each one, on a single machine: what carries over to your site is the order, not the exact figure.
PHP files loaded on every page view: 26. SureRank 122, SEOPress 134, Rank Math 267, All in One SEO 303, Yoast SEO 588.
Database queries added to a post: none. SEOPress 1, Yoast SEO 3, SureRank 7, Rank Math 16, All in One SEO 32.
Server time added to every page view: about 2 ms. Yoast SEO 7, SEOPress 8, Rank Math 11, SureRank 12, All in One SEO 17.
JavaScript loaded in the editor: 41 KB. SEOPress 89 KB, Rank Math 1.4 MB, SureRank 1.9 MB, Yoast SEO 3.5 MB.
Download size: about 505 KB. SEOPress 2.8 MB, Rank Math 3.6 MB, Yoast SEO 4.9 MB, SureRank 6 MB, All in One SEO 7.3 MB.
Custom database tables and cron jobs: none. SureRank 0 and 1, SEOPress 1 and 0, Rank Math 6 and 4, Yoast SEO 6 and 6, All in One SEO 13 and 1.
Security
Every release passes a security audit of the changed code before it ships.
Small attack surface: no custom tables, no unauthenticated endpoints, escaped output, validated input and prepared database queries.
No telemetry and no data collection.
