Quick example scenarios

  • A publisher with 8k evergreen posts turns on Social Media & Open Graph Manager and clears orphan pages in a single approval batch.
  • A SaaS site adds FAQ schema across product docs and starts appearing in AI Overviews within two crawl cycles.
  • An agency runs a per-silo 90-minute audit weekly instead of a quarterly PDF audit.

Paired module: GEO — Generative Engine Optimisation

Optimisation for how ChatGPT, Gemini, Claude, Perplexity and Google AI Overviews retrieve and cite your content — llms.txt, extractability, factual density and citation-worthy formatting. AI answer engines route intent before the SERP does; being invisible to them is being invisible to the top of the funnel.

  • Enable GEO mode in SEO Features
  • Publish llms.txt with cited pages and license terms
  • Audit posts for extractability (short facts, clear headings, TL;DR)
  • Track citations in the AI Rank Tracker weekly
SVG or PNG?

SVG if your theme supports it. Otherwise WebP.

Retina?

2x the dimensions, serve via srcset.

Do the auto-generated share images count as duplicate media?

Each image is generated per post with a unique title, author and hero — they share a template, not the file, and are cached at the edge.

Is GEO just SEO with new labels?

It shares the discovery layer, but the ranking function is different — LLMs weight extractability, factual density and entity clarity far more than backlinks.
