Technical, content, linking and schema issues are surfaced continuously, ranked by impact, and resolved with a single click inside WordPress.
Claude reads your Search Console numbers and plan through an MCP connection, proposes the week's actions and applies them only after your approval — read-only by default, every call logged.
A dedicated module asks ChatGPT, Gemini, Claude and Google every night which brands they recommend and shows where a competitor is cited instead of you.
The plugin groups content by topic, links related pages together in the right direction and surfaces cannibalization so one page owns each search.
