The Candidate Quality by Campaign report provides insight to the effectiveness of your ad campaigns by revealing which campaigns return the most candidates — and more importantly, the highest quality candidates — by assigning each campaign a Quality %.
The Quality % is computed by looking at the average distance a candidates travel through the pipeline. If every candidate was hired, it would be 100%. If every candidate was rejected in the first stage, it would be 0%.
Example: Let's say candidate Jane applies through one of your ad campaigns. Jane has a pretty strong background, so she makes it through 5 of your 7 stages. If she was the only candidate to apply through that campaign, your Quality % for that row would be 5/7, or roughly 71%.
