The data provided in this prompt is insufficient to complete the analysis as requested.

The JSON payload contains complete data for Bet365 (logged_out and logged_in mobile captures) and a partial record for William Hill (cut off mid-object, missing promo_offers, nav_items, and remaining fields). No other sites are included — the outside-industry sites (Netflix, Revolut, Spotify, Deliveroo), BoyleSports, and the remaining 16+ competitors referenced in your data context are not present in what was passed here.

As a result, I cannot:

  • Rank sites by above-the-fold content density (only 1 complete site available)
  • Compare outside-industry vs. sportsbook mobile patterns (no Netflix/Revolut/Spotify/Deliveroo data)
  • Identify which sites use progressive disclosure across the competitive set
  • Draw Implications for BoyleSports without BoyleSports' own data to check against

What I'd suggest: Re-send the prompt with the full dataset included — all 21 sites' mobile captures. Given the volume, it may be worth splitting by category (e.g. sportsbooks vs. outside-industry) if the payload is hitting a length limit. Once I have the complete data, I can run the full analysis against all the output format requirements you've specified.
