Auction Technology Group - Default Sort Order

Hypothesis - Does re-sorting search results based on Relevance rather than Auction Date increase user engagement and sales? When users perform a search on one of ATGs Industrial and Commercial websites ( and, the results will be sorted by relevance. By serving more relevant results this should benefit users more than the most recent auction dates.


An almost straight flush of positive uplift across both websites. It was noticed that many of ATGs competitors were sorting results by relevance rather than auction date, and running this test proved that this sort order is the correct decision for conversion and for users. The low engagement on the Sort By filter demonstrates how important relevant results are to a customers search. A 7% increase in bids being placed was a phenomenal result.
