Best Practice #3 — Treat Reviews as CTR and Conversion Assets

Product reviews influence both click-through rate and conversion rate.

  • Offer incentives for verified reviews.
  • Request reviews within 2–3 days post-purchase.
  • Enroll in Google Customer Reviews for seller ratings.
  • Respond to negative reviews promptly.
  • Use authentic customer photos in ads.

AI bidding and automation can scale campaigns but require controls.

  • Enable Automatic Item Updates, but verify key SKUs manually.
  • Use Target ROAS or Max Conversion Value with budget caps.
  • Deploy Dynamic Remarketing with product-level personalization.
  • Set up scripts or rules to pause poor performers and reallocate spend.
