Google Shopping Optimization: The 10 Most Common Google Shopping Errors


If you have ever run a Google Shopping campaign, you know that Google can be very strict about its product data feed requirements. In order to run any Google Shopping ad, you must provide data on at least 10 attributes for every single product, follow several formatting rules, and ensure that all data is clean and up-to-date. With all of the requirements, it’s easy to make mistakes that lead to poor returns.

In fact, there are several mistakes a business can make that will lead to product disapprovals or even account suspension. In order to help businesses keep their Google Shopping ads live and thriving, we met with Google to find out what the most common Google Shopping errors are. This is what we found.

Top 10 Google Shopping Errors:

Error 1: Missing Required Attributes

Remember those 10 required attributes absolutely every feed must include? It’s very common for marketers to miss one or two. Common issues include additional attributes required for specific types of products. For example, those selling clothes need to also include color and size.

Skipping any required fields can lead to product disapproval. If possible, analyze your feed before submitting it to Google to ensure all required information is included.

Error 2: Duplicate Product Titles

Many advertisers will submit multiple products with the same title. This common practice can directly hurt returns, as a product title is a key driver of clicks and sales. A good title helps shoppers determine whether the product is right for them. A bad title does not intrigue shoppers and will not lead to conversions.

Consider this attribute a great opportunity to drive more sales by infusing basic titles with keywords and selling points that matter to shoppers.

Error 3: Discrepancy Between Shopping Feed & Landing Page Content

Product ads should always successfully link to the related product page. This brings us to the next error: discrepancies between the Shopping feed and the landing page.

Imagine clicking on an ad and landing on a page with different product details. Maybe the product listed is now more expensive, in a different currency, or in the wrong color. This leads to a bad experience for the shopper and a possible account suspension for the seller.

There are several steps that can help combat this error:

  • Make sure that Google always has the most up-to-date product data. That way, the feed will accurately reflect any product or landing page changes that have been made.
  • Leverage schema.org markups and use Automatic Item Update.
  • Always be aware of mobile links.
  • Submit a standardized color (like “dark blue”) in the color attribute and use the title to display specific colors like “midnight blue” or “cobalt.”
  • Stay on top of common problem attributes like price, currency, and color.

Provide a good customer experience by ensuring your shopping feed and landing page content match.

Error 4: Empty Product Categories

Google product taxonomies are complicated, and it’s easy for advertisers to include product categories that are incorrect or not properly mapped. However, Google relies on these categories in order to understand the exact nature of a product. Incorrect or missing category data can stop products from surfacing for the most relevant searches and audiences, resulting in poor performance.

There are not many workarounds for this step, so it may require manual work and attention. Advertisers using PIM (product information management) software should consider setting a fallback category in case there is no category assigned to a given product.

Although tedious, making sure your taxonomies are set up correctly is a critical step for Google to understand your products.

Error 5: Adding Custom Columns to the Google Feed

Google allows up to 5 Custom Labels to be used in a Shopping feed. These allow marketers to pair products with any particular data point, such as price range, season, historical ROI, or anything else. However, do not confuse the Custom Label with a custom column.

Including columns that Google doesn’t recognize will cause the feed to be disapproved. Instead, for these purposes, use Custom Labels.

Error 6: Images are Either Invalid or Too Small

An image can say 1000 words—unless they get your product disapproved. Then, they don’t say anything. There are numerous reasons an image could be disapproved, so it’s important to always follow Google’s rules and best practices.

  • Be sure the image is at least 100×100 pixels (250×250 for apparel)
  • Never add banners, copy, or other promotional information

Not following these guidelines can lead to products being disapproved.

Error 7: Adding Redirect Parameters to the “Link” Column

It can seem obvious to add tracking parameters to the product’s URL. However, each time Google crawls the link, that will lead to a fake click. The result will be a lot of bad data.

Always opt for a plain link in order to avoid fake clicks.

Error 8: Incorrect Format for “Tax”

While Google requires tax information to be submitted, it’s not always easy to do so correctly. Tax rates can vary even from state to state, making it infinitely more difficult to get the data right. Up to four sub-attributes can be provided within the one tax value.

These attributes are:

  • Country – optional
  • Region – optional
  • Rate – as a percentage
  • Whether tax is charged on shipping – accepted answers are yes or no

The standard format is: country (optional): region (optional): rate (as a percentage): whether tax is charged on shipping (accepted answers are yes or no).

An example would be: US:SC:6.00:y

Tax rates vary from state-to-state so double check that you have the correct information for your business.

Error 9: Missing GTIN

Businesses can spend hours hunting down product GTINs. It can be time-consuming, but these identifiers are absolutely crucial to any product listing. They allow Google to recognize the product in question. Whether it’s listed in Japan, Canada, or China, these numbers accurately identify the product every time.

There are companies who offer services specifically for locating GTINs, but these numbers can also be found online, on product packaging, or even in supply chain systems and supplier information.

GTINs help Google accurately identify products regardless of where they are listed.

Error 10: Keyword Stuffing or Promotional Text for Product Type

Marketers often try to add keywords or promotional information to the product type in order to stand out from the crowd.

For example, turning: Shoes > Sneakers into Shoe > Sneakers > Shoe > 50% Off.

Product types however simply do not function this way. This will not help make a product more visible or appealing. In fact, it can lead to account suspension. Keep the product type clean and clear; save the exciting information for another attribute like Description.

Keyword stuffing could lead to your Google Shopping account being suspended.
