Simprosys Google Shopping Feed

It is a perfect and helpful app for managing your feed for ads and free listing. I like that I can only modify product titles and other attributes in the feed for better search results and don't need to change details on the Shopify store product page.
Also, support is very responsive. Recently, I had a problem related to tax calculation in Google ads, and they resolved it very quickly. It wasn't their fault; rather, it was associated with Shopify markets and how they calculate VAT. I highly recommend this app to anyone who wants to manage ads and free listings.
There are many different settings available, as well as connections to Facebook, Pinterest, and Bing ads.
