Before the offer goes live
Confirm stock or appointment capacity, publish the page and complete the buying journey on a phone. Establish who handles enquiries and which action counts as a sale or booking. A broken checkout or unanswered request will not be solved by more advertising.
While Christmas demand is active
Keep the promotion aligned with availability. Shipped gifts, local collection, installation work and dining reservations have different cutoffs. Use your verified operational deadline rather than copying a national date into every campaign.
When the promise changes
Retire expired offers promptly. Switch to local pickup, later appointments or January visits only when those options are genuinely available. Keep the ad, landing page and confirmation message consistent.
After the rush
Review fulfilled orders, attended appointments, refunds and missed visits. Record what the team could not deliver as well as what sold. That is a more useful starting point for the next campaign than a screenshot of impressions alone.
