Smush – Image Optimization, Compression, Lazy Load, WebP & CDN vs Agentic SEO for Visibility

Agentic SEO for Visibility is the official WordPress plugin for Visibility, a SaaS platform that runs AI agents to audit websites, generate SEO-optimised content, and publish it directly to WordPress. Pair your site with your Visibility project in under a minute using a short code — no Application Passwords, no per-user API keys, and no copy-pasting drafts out of an AI tool. Why use this plugin No Application Password required. Pairing exchanges a one-time short code for a shared site token, so the plugin and Visibility can talk without a WordPress user password ever leaving your site. Built for agentic SEO workflows. Visibility’s AI agents can list, draft, update, schedule, and publish posts on your behalf — including categories, tags, featured images, and excerpts. Drafts by default; publishes only when you allow it. Every post is saved as a WordPress draft unless you’ve enabled “Allow publishing” on the agent in your Visibility project, so a human can always review AI-written content before it goes live. Compatible with Yoast SEO, Rank Math, and AIOSEO. Posts go through the standard WordPress post-save flow, so SEO-plugin meta boxes, schema generation, and sitemap entries populate the same way they do for posts you write by hand. Works on any WordPress 6.0+ install. No special PHP extensions, no server tweaks, no host control-panel toggles to flip. Open source (GPLv2). Plugin source lives at github.com/doable-team/agentic-seo-for-visibility. How it works In your Visibility project, click Connect via plugin and copy the short pairing code (for example VIS-A7K9-XB). Install and activate this plugin, then open Agentic SEO → Connection and paste the code. Your project and this site are paired. AI agents can now read, draft, and (when enabled) publish WordPress content here. You can disconnect at any time from Agentic SEO → Connection, or from the Visibility dashboard. A Visibility account at app.visibility.so is required. See the External services section below for the full list of network calls this plugin makes. External services This plugin connects your WordPress site to Visibility, an external SaaS service at https://app.visibility.so. A Visibility account is required. The plugin makes the following outbound HTTPS requests from your site: POST https://app.visibility.so/api/wordpress/plugin/pair — sent once when you submit a pairing code on the Agentic SEO → Connection screen. Body includes: the pairing code, your site URL, site name, WordPress version, and the installed plugin version. Response contains a shared site token plus the connected company + project IDs and names so the plugin can display them. POST https://app.visibility.so/api/wordpress/plugin/heartbeat — sent at most once per day from WP-Cron while the plugin is paired. Body includes the installed plugin version; the shared site token is sent in the Authorization: Bearer header. Used to refresh the “Last seen” timestamp and pick up renames of the connected company or project on Visibility’s side. POST https://app.visibility.so/api/wordpress/plugin/disconnect — sent when you click Disconnect on the Agentic SEO → Connection screen. Body includes the installed plugin version; the shared site token is sent in the Authorization: Bearer header. Tells Visibility to remove your site from the project. Local cleanup proceeds even if Visibility is unreachable. Inbound requests from Visibility, authenticated with the shared site token, reach the plugin at /wp-json/visibility/v1/* and are used by your Visibility project’s agents to read, draft, publish, update, or delete posts; manage categories, tags, and media; and check site health. No content leaves your site automatically — content only travels on agent-initiated requests originating from the Visibility project this site is paired to.
