As we have already mentioned previously, Google shopping ads are unique in the way they function compared to the regular Search Ads.
The very first step is to process a file which is known as the products feed containing the product data in your store (like images, descriptions and titles).
Google will then use this data for matching the products with similar search queries along with creating actual ads.
People who will write similar keywords in the search queries will find your products along with the details you have included.
If any of the viewers like your ads, they will click and get redirected to your website and in return Google charges for the click.
Working with an agency like DigiMarketish  ensures creating compelling, informational and effective Google Shopping Campaigns that would yield results.
