WordPress plugin (one-click fixes)

The WordPress plugin connects your WP install to a SEMOptimiser site. Three capabilities: auto-IndexNow on publish, in-editor SEO score, and one-click fixes from audits applied directly to WP.

Install

From the WordPress directory (recommended)

1. WP Admin → Plugins → Add New → search "SEMOptimiser".
2. Install + Activate.
3. Click Connect in the new SEMOptimiser menu in the sidebar.
4. OAuth flow bounces to SEMOptimiser. Pick workspace + site. Authorize.
5. Bounced back to WP, plugin shows "Connected".

Manual upload (for air-gapped or firewalled WP)

1. Download the plugin .zip from Settings → Integrations → WordPress → Download plugin.
2. WP Admin → Plugins → Add New → Upload Plugin → pick the .zip.
3. Install + Activate.
4. In SEMOptimiser, generate a Client ID + Secret (Settings → API Credentials).
5. In WP, paste them into SEMOptimiser → Settings → Connection.

Required WP capabilities

The plugin uses the user's capabilities – there's no service account. The connecting user needs:

• `edit_posts`, `edit_pages`, `edit_others_posts` – to apply content fixes.
• `edit_themes` – to apply theme-level fixes (canonical, viewport meta).
• `manage_options` – to configure plugin settings.

Auto-IndexNow

On every publish or update of a post/page/CPT, the plugin POSTs the URL to our IndexNow endpoint. Configure which post types trigger it in SEMOptimiser → Settings → Auto-submit. Default: posts + pages (not custom post types).

Editor sidebar

In Gutenberg, a SEMOptimiser panel appears in the right sidebar. Shows: current SEO score (recomputed live as you type), AI-readability score, missing meta description warning, image alt completeness, fixable issues list.

One-click fixes

When an audit completes, fixable issues appear under WP Admin → SEMOptimiser → Fixes. Click Apply on any issue. The plugin uses native WP APIs (`wp_update_post`, `update_post_meta`, `wp_insert_attachment` for images) to apply changes.

Multisite

Plugin supports WordPress Multisite. Network-activate, then each subsite admin connects independently. Network admin sees a roll-up across all connected subsites.

Caching plugins

Compatible with: WP Rocket, W3 Total Cache, LiteSpeed Cache, WP Super Cache, Cloudflare. The plugin purges affected URLs from each cache layer after applying any fix. If you use a less-common caching plugin, fixes still apply but you may need to manually purge.

Uninstall

Deactivate + delete from WP Admin → Plugins. The OAuth token is invalidated automatically. To revoke from the SEMOptimiser side too, Settings → Integrations → WordPress → Disconnect.
