Find keyword gaps: queries where you rank 11–50 but competitors likely rank 1–10

Pull my main Search Console property's data and find keyword gap opportunities over the last 28 days:

1. Pull all queries with average position between 11 and 50 AND at least 500 impressions. Group them by the landing page that ranks for each query. For each group, identify:
   - The cluster theme (the shared topic connecting the queries in that group — 3–5 words)
   - The top 3 queries by impressions, with each query's impressions and average position

2. For each landing page group, provide ONE content improvement recommendation from the following options (pick the best fit based on the queries):
   - ADD_SECTION: the page is missing a subtopic the queries imply
   - REWRITE_INTRO: the page covers the topic but the intro doesn't match search intent
   - TARGET_FEATURED_SNIPPET: query phrasing suggests a definition or step-list answer; restructure to win the snippet
   - ADD_FAQ_SCHEMA: multiple question-style queries — FAQ schema would capture PAA boxes

3. For each landing page, identify ONE other page on the same site (already ranking positions 1–10) whose content is most naturally adjacent — that page is the best candidate to add a contextual internal link from.

Sort the final output by total impressions per group descending. Format as one section per landing page, with a summary table at the top.
