Constructive criticism from someone with a lot of time doing this sort of thing:

The ads are so busy that it's distracting even when looking at them. All of the different colored ad-specific banners and sashes plus prices and icons are trying to convey - in my opinion - too much at once. Adding in the visual noise from the grey dotted line it's rather difficult to consume. There's a lot of visual noise.

I'm also unsure that as a buyer, I really care if it's in the shop / marketplace / classified. There are already icons at the bottom (the cart vs the location) that helps me differentiate that data point already. If it's important information, having it clear as day on the next page should do the trick, but I suspect that it isn't actually important to buyers.

I would also suggest changing the "featured" sash to a different colored background and removing the 'sash' from the image.

The ads are better for buyers and sellers, and should be good for Pinside. This how free sites stay in business and I applaud you for not simply going the Google Ads route with lots of other irrelevant ads. I hope this works out for you.
