All merchants who run pay-per-click advertising on Google generally have a decent idea about how Google Shopping feed works and how to leverage it. No matter how much it is optimized for search, there is always more than can be done to keep up with new trends. 

The pay-per-click is a constantly evolving industry that, coupled with AI learning advancements, makes it easier for merchants to save time with advances such as Google’s Smart Bidding. With more automation saving time, it is possible to improve the search campaigns and enhance them for better and more relevant visibility. 

What is Google shopping feed enhancement? 

In short, the Google shopping feed is a spreadsheet that organizes and stores all the critical data from your product catalog in such a way that Google can extract precisely the data it needs when it crawls. Therefore that puts the majority of the control of how you show up in search in your hands. 

Although it pulls out product attributes using all of its technical might, it is only as good as the relevant information you give to the feed. To show up in the most relevant search terms, the keywords in product titles and descriptions are what Google looks for.  

Quite often, the product titles sold by merchants dont include the critical terms that are needed to show up in relevant searches. It also applies to descriptions as merchants could get carried away by the technicality of the product and forget to add terms that make it suitable in search. 

This is more common in generic shopping feeds containing the core attributes but nothing specific to the product. Generic descriptions always attract generic traffic that is less likely to convert. 

Although you might be ahead on the conversion journey of a prospect, it is easy to fall behind with poor feed attributes as they continue with their research and are ready to make a purchase. Ultimately it will be a waste of money spent on sales that gains very little or nothing in return. 

While it is a bit more taxing on time, efforts spent on google shopping feed enhancement can reach returns on investment that PPC management alone cannot do.

  • Product Description: The description must accurately fit the product and suit the description given on your website’s landing page.

Why should you enhance your google shopping feed?  

There are several advantages to google shopping feed enhancement

  • It improves relevance: enhancing your shopping feed is all about fine-tuning data to perfectly fit what the Google Shopping algorithm expects. When someone searches for your product, the algorithms use keywords, categories, and product identifiers such as GTIN, descriptions, and more to pull up everything related to it. To stand out among the thousands of search results, your feed will have to be complete and thorough. The closer the information in your feed matches the search, the more likely you will be shown in the result. 
  • Improved conversion and ROI: The goal of listing on Shopping Ads is to come up in as many relevant searches as possible and make the conversion to drive your return on investment. When so much of your ad money is going into it, you must make a first impression on a prospect and nudge them toward conversion.
  • Outshining competition: There might be hundreds or thousands of other merchants with the same products as yours who are given the same set of constraints to work with. The level of detail you give to your shopping feed will help you float to the top in the crowded shopping channel. Constant enhancement of the feed ensures you are close to the search terms and stay relevant despite the competition. 
  • Advanced campaign enhancement strategies:  The custom label attribute can be used in your shopping campaigns to group best-selling items or items that fall under a price range that go according to the trends of the season. You can diversify bidding for specific groups or even make separate campaigns. 

How to enhance your google shopping feed?

Ways of enhancing your google shopping feed

Manual enhancement

To enhance your shopping feed manually, you need to know and understand the depth to which every attribute can influence your relevance. And accordingly, the shopping feed needs to be modified. Here are some of the features that can be manually enhanced: 

  • Description: The descriptions not only need to be optimized for keywords but should also be relevant in describing the product such that it is easily understood. It shouldn’t contain information about compatible products, or similar products, or use unfamiliar words. It also needs to be grammatical and professionally written without spelling errors. 
  • Availability: The availability of the product should be regularly updated so that google and users can know how much is in stock, what is out of stock and what can be preordered. 
  • Condition: Condition is a mandatory item for all products that are used or refurbished. It is optional for new products. However, it can be added to all products to improve search results. 
  • Brand: The brand attribute must be clearly defined to help identify the product. It should also be visible in the images of the front packaging to associate the product with the brand and refine search results. 


  • Every product attribute that goes into the shopping feed can be controlled by you. 
  • Works well for customized products and exclusive items sold by the merchant. 


  • Extensive knowledge about google shopping feed is necessary to get it right. 
  • Updating manually every day can be labor-intensive. 
  • Dynamic parameters that can change, such as availability, cannot be changed instantly.

The higher the score, the better chances your product has in performing well in Google shopping ads. These are the product characteristics that show recommendations in the app: 

  1. Title: The tile is your most important attribute as google compares the search queries with available titles and pulls up all the relevant results. To optimize this further, the title should include the keyword and other attributes that associate the product with the type, gender, color, size, design, etc. Using trial and effort on the app, you can develop solid titles and find scores under the full analysis tab.
  2. Description: As mentioned before, the description should be an exact match to what is on the landing page of your website while also describing the product with relevant keywords. The app can analyze and score your description for effectiveness to be improved before sending it to the feed. 
  3. Google Product Category: The product categories must be clearly defined to help the search engine with its taxonomy.  Getting the subcategories right can make the difference between what is shows as relevant and what fades into the background. It is important to remember that there is no such thing as too much information when it comes to classifying the product! 
  4. Product Type: Product type gives google the other metric to classify your product more accurately and improve the relevance of your search. This becomes more important when selling excellent products or selling similar products with different user bases. When in doubt, use the analysis tab to develop a score for the product type attribute. 
  5. Promotion Ids: Promotion Ids can be used as identifiers that match the product data to promotions offered by merchants. Its essential to use unique Ids and the same promotion Id in the promotion data and product data. The app can also give scores based on tests. 
  6. Images: The images always have to be of high resolution or have enough detail to show the product clearly and the brand. It should also not have watermarks, promotional texts, or borders around it. Appealing images can significantly improve the first impression and are consistently scored higher in the optimization of ads.
  7. GTIN: The Global Trade Item Number is essential for all products. Every manufacturer must submit the product GTIN, which can be used as accurate identifiers for shopping ads. Getting it right will significantly boost your ad performance.
