# List Recommendation Types

> List a brand's optimization recommendations grouped by type — one row per best practice, with the projected site-score lift (`site_impact_pp`), how many pages it touches (`page_count`), and where those pages sit in the pipeline (`pending`/`reviewed`/`staged`/`deployed` counts).

Counts and lift span the whole brand and match each type's detail view. For a brand using the Site Optimization page selection, they cover its enabled pages instead. Ordered most-affected first.
