To see your product appear above the search results and within the “sponsored” section, you need to run Google Shopping Ads. As with any Google Ads campaign, you’ll need to have the ads set up correctly with a sufficient budget to appear within the first few spots.
That said, you can also have a free listing. Free listings don’t appear at the top of search results and appear below the sponsored listings in the “Shopping” tab. While not as effective as Google Shopping Ads, a free listing can still allow your product to be noticed.
Think of it as a featured and regular free listing. Featured listings get higher positions, but sellers need to pay for the advantage. Free listings will still be visible, but only after users have scrolled past the sponsored products.
