Aaron Dicks shared with me on Twitter a weird display for the Google Product Listing Ads/Shopping ads (or whatever they are called now). The ads show as they normally do but the product titles are highlighted in this dark blue color.
Here is a screen shot:
I doubt this is something Google is actually testing. Well, you never know. It looks like more of a bug with Google or an issue with Aaron's browser. The unusual part is that seconds after he saw it, he tried to replicate it and was unable. So it seems like either it was a Google test or a bug.
I certainly hope we don't see this in the search results anytime soon.
