This could get interesting. Last month, we saw Google running a test that ranked product listing ads (PLAs) by ratings and reviews in search results. Now, a new test groups and ranks products by price.
In the screenshot below, provided by CPC Strategy, PLAs are grouped in two pricing stacks — one for “Up to $30″ and a second for “Over $30.” The products in the first group are shown in order by price. Oddly, there is one outlier in the second group — the $36.95 sandal from Nordstrom is listed after two higher priced shoes from Keen.
This test could obviously have a big impact on pricing strategies for e-commerce advertisers. Monitoring could also be cumbersome if the pricing cut-offs range by search result and/or product type.
