原文外掛簡介
Visibility is the SEO essentials without the suite. It covers what most sites actually need (meta tags, canonical URLs, Open Graph, JSON-LD schema, robots directives, redirects, AI discovery with llms.txt and Markdown for agents, robots.txt editor and native XML sitemap control) in about 268 KB, with no Pro tier, no upsell banners and nothing phoning home. It is built on WordPress core APIs (wp_robots, wp_sitemaps_*, register_post_meta, the Block Editor), so most of the work is the platform’s, already optimized.
Coming from Yoast, Rank Math, All in One SEO or SEOPress? Visibility imports your titles, descriptions, robots, Open Graph, schema and redirects in one click. The clean metadata it outputs is what search engines and AI assistants (ChatGPT, Perplexity, Gemini) read to understand and cite you: the AEO/GEO angle without the bloat.
Four modules, toggled independently from Overview:
Discover — meta title and description, Open Graph and Twitter Cards, Article/BreadcrumbList/Person JSON-LD with a selectable schema type per content type, FAQPage from Details and Accordion blocks, and Site Identity, plus AI discovery: llms.txt, Markdown for agents and a robots.txt editor. Author expertise feeds the Person schema, and a freshness filter flags stale content. Per-post and per-term overrides for all of it.
Indexing — bulk or per-item noindex / nofollow by post type and taxonomy, with rules for search, 404, date, paginated, attachment and author archives plus RSS feeds. Remove the base of any taxonomy one by one, pick a WooCommerce product URL structure, redirect attachment pages to their parent, all with 301s. Quick Edit, Bulk actions and a Robots column on your lists.
Sitemaps — control over the native XML sitemap: exclude post types, taxonomies, users, posts and terms; lastmod dates; 301s from old sitemap URLs; noindexed content stays out automatically.
Redirects — a lightweight 301 / 302 / 307 / 410 manager resolved in PHP (no .htaccess, no custom table, no 404 log), with CSV import / export, suggested redirects when you delete a post, and WordPress slug-change redirects you can take over.
Per-post controls live in the Block Editor panel and a matching Classic meta box. A Tools tab groups the importers and exports your configuration as JSON for another site.
Visibility replaces a full SEO suite rather than running alongside one (two would fight over the
Perfect companions
Visibility is fully independent — these plugins aren’t required — but they pair really well with it:
VigIA — AI visibility, crawler analytics, Site Identity JSON-LD on the home page. Visibility coordinates @id references with VigIA so both can add schema without duplicating the Organization or WebSite nodes.
Share Buttons & AI-powered Summaries — share buttons for social networks and AI assistants. Helps your content reach both audiences and language models.
AI Content Signals — control how AI systems can use your content (training, search, both) through robots.txt directives endorsed by Cloudflare.
Vigilante — all-in-one WordPress security: firewall, login protection, security headers, 2FA, file integrity monitoring.
External services
This plugin connects to Gravatar (operated by Automattic Inc.) to check whether the post or page author has a public Gravatar avatar, so it can be exposed in Open Graph tags (og:image) and in Person JSON-LD (image) for E-E-A-T.
What data is sent and when:
When a singular view is rendered and the Open Graph module is active, and no other image source exists (per-post og:image, featured image, WooCommerce gallery image, inline content image), the plugin sends an MD5 hash of the lowercased and trimmed author email to https://www.gravatar.com/avatar/{hash}?d=404 via wp_remote_head() (HEAD request, no body).
When an author archive is rendered and the Person schema module is active, the same probe is performed for that author.
The original email address is never sent — only an MD5 hash, which is the standard Gravatar lookup mechanism.
The result (found / not found) is cached for 24 hours in a transient so subsequent page loads do not hit Gravatar again.
This is the same mechanism WordPress itself uses to display Gravatar avatars in comments. 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 (2.1.1)
Download size: about 268 KB zipped.
Codebase: 43 PHP files, roughly 22,100 lines of PHP.
Zero custom database tables. Settings live in a single autoloaded option; per-post, per-term and per-author values use native WordPress meta that is already in the object cache.
Zero cron jobs and no scheduled background processes.
Zero external HTTP calls, with a single exception: a cached Gravatar HEAD probe (24-hour TTL) that exposes the author avatar for E-E-A-T, the same lookup WordPress already performs for comment avatars.
Built on WordPress core APIs (wp_robots, wp_sitemaps_*, register_post_meta, get_canonical_url, the Block Editor), not private reimplementations, so most of the work is the platform’s and already optimized.
Security
Every release passes a security audit of the changed code (sanitization, escaping, nonces, capabilities, SQL) before it ships. It is a release gate, not an afterthought.
Minimal attack surface by design: no custom tables, no unauthenticated endpoints, output escaped where it is printed, input validated against allowlists, and prepared statements for every database query.
No premium tier, no telemetry, no data collection. Nothing phones home.
A smaller surface is a smaller target.
