The Placement Audit That Reveals Why 60% of Your Banner Spend Generates Zero Revenue
The data audit that identifies which publisher placements waste your budget on traffic that never converts
Your campaign runs on 40 publisher sites and the network dashboard shows consistent impressions and clicks across all placements.
But when you dig into actual conversion data, you discover that 23 of those sites have never generated a single sale despite six months of ad spend. The network keeps serving impressions there because the clicks look legitimate and the sites meet basic quality thresholds. You are paying for traffic that has zero chance of converting.
Building the Placement Performance Matrix
Export your last 90 days of campaign data and create a spreadsheet with these columns: publisher name, impressions, clicks, CTR, sessions, bounce rate, pages per session, conversion rate, and revenue. Sort by revenue descending. The bottom 40-60% of placements typically generate less than 5% of total revenue.
Calculate cost per acquisition for each placement individually. Many will show infinite CPA because they have never converted. Others will show CPAs 5-10 times higher than your profitable placements. These are not underperforming placements that need optimization, they are fundamentally wrong audiences that will never convert regardless of creative or targeting adjustments.
The Engagement Pattern That Predicts Zero Conversions
Look at bounce rate and time on site together. Placements with over 75% bounce rate and under 30 seconds average time on site are delivering bot traffic or completely mismatched audiences. Real users who might eventually convert spend at least 45 seconds and view multiple pages, even if they do not purchase immediately.
Exclude any placement with zero conversions after 5,000 clicks. That sample size is large enough to prove the audience will never convert. Redirect that budget to your top six performing placements, which typically drive 80% of revenue despite receiving only 35% of impressions.
