Home › Account Building › Shopping Feed Optimization: A Prioritized List of Improvements to Your Feed
January 24, 2022
Google Shopping feed optimization is something that most advertisers ignore.
It hasn’t been prioritized by most, and many have seen great results over the years (and even greater since Smart Shopping came for a lot of advertisers). But ignoring your feed means leaving money on the table.
When Google Shopping just got to the market, you’d see amazing results. Now you need to work for it.
You delay working on your feed because it’s not easy. You need a tool. You need to know where to start. You need to know what to do. For many, it’s a brand-new set of skills.
This article will help you do three things:
If you run Smart Shopping, feed optimization is one of the primary things you can do to help your Shopping campaigns improve. Even if you are happy with your performance now, this article can help take your performance to the next level.
But first, why should you optimize your Google Shopping feed?
There are two main reasons to engage in Google Shopping Feed optimization: increased exposure and a better campaign structure.
The more (accurate) data you provide to Google, the better Google will rank your products, which creates increased exposure. Yes, your bid is the ultimate factor in how many impressions and clicks you get, but think of your feed quality as the bottleneck.
The better your feed quality, the larger the bottleneck.
In 2018, when I first wrote this article, I had it on good authority that Google was increasingly looking to Google product categories, GTINs, brand, and other fields to find what searches your Shopping Ads should appear for:
The better Google can triangulate where to display your products without the need for a specific keyword in your product title, the better they can link you with the relevant search queries.
Today, this is even more important than ever.
Your feed is your campaign structure. If you don’t have proper product types, brands and/custom labels, you can’t build an optimal campaign structure.
Setting different targets based on margins, product prices, brand, or categories requires that all those values are in the feed.
The better you make your feed, the higher the relevancy you’ll get.
Allow me to drift a bit to make my point. In Google Hotel Ads, the platform is more transparent when it comes to feed quality (or account health as it’s called).
Google specifically decreases your feed quality based on how relevant the price in your feed is compared to the price on your website. Pricing accuracy in Google Hotel Ads is everything.
So it’s not a big stretch to think that there is an equivalent direct correlation between the quality of the data in your Google Shopping feed and its “quality score.” The better your feed, the more searches you’ll appear in, and more frequently.
I highly recommend applying as many values to your feed as often as you can. Spending time upfront to make sure you have all your feed values as accurate as possible can really help you in the long run.
Things that directly influence your position, like title optimizations, can often have a quick impact. Fixing things in your feed that result in disapproved products being approved again will also clearly have a big impact on your results.
Other areas have longer-term effects. Building up your feed to include the most accurate Google product categories, colors, GTINs, and so forth will not have an immediate effect. But, over some time, you’ll start to see increases in clicks and impressions. (Remember that increased exposure I mentioned earlier?)
The attribute is the type of field.
The product data is the data for each product that you submit through your feed.
If you think of the feed as a spreadsheet, then the attribute is the header, and the attribute value is a cell value for each header (attribute).
Here is an actual example:
Google has a useful documentation article on what product data should be included in your field. However, it’s also a long list, and it’s confusing to prioritize what data to work on first.
Still, once you get the hang of feed optimization, the documentation from Google is pretty good.

Reviewing your own feed right now, you might think, jeez, I don’t have 19 attributes in my feed. Where do I start?
That’s what we will go through next.
My overview of optimization priorities have been split into three sections:
If you are mostly curious about how to optimize your feed, feel free to jump to the Optimizing Existing Attributes section.
The first thing you should do is add all the required attributes you are currently missing.
Copy our spreadsheet so that you have one place to see the status of your feed.
Then review the attributes you currently have in your feed. The easiest way to do this is directly in the Merchant Center. Just open a random product, and see what is currently being sent to Google.
As you can see, the attributes are all fairly easy to add. Some of them might take some time if the data is not in your e-commerce platform—most often this is the GTIN attribute.
After adding the required attributes, do the same exercise for all the recommended attributes—in prioritized order. Soon, I will explain why you should add all these attributes before starting the actual optimization of the individual attributes.
I recommend reading the optimization section below to understand how to add certain attributes.
This is where all your work in adding the correct attributes to your feed pays off. Not only have you increased the overall quality of your feed, but you can now use those fields to optimize individual attributes.
Some attributes are black and white. They are what they are. But a handful of attributes can vary greatly in quality.
The following attributes should be optimized specifically for Google Shopping:
Below, I go into detail about optimizing each attribute.
Product titles are the single most important area that you can optimize in your feed.
There is a very simple reason for this: the keywords in your product title are a prominent factor in determining which search terms your products will appear for.
As an example, once I added some basic rules that meant we added keywords to the product titles, and our traffic increased by 4x. I had to decrease the bids for it not to run away from me! This is a month-long view of that campaign:
Notice how old the screenshot is!
I’ve delved into title optimization in a separate article, so I will just highlight the most important aspects here:
The most frequently searched for keywords are categories, brands, and product titles (besides generic searches).
Therefore, your first step should be to add the brand and category to your titles.
This can literally be anything you can think of. But again, having a well-structured feed comes into play. If you don’t have size, material, and so forth in your feed, you can’t add them to your product titles.
Some good examples include:
This is my least-used tactic, but I recommend it from time to time. There are certain high-performing products where customizing the title can really pay off.
The value of proper descriptions for your Shopping feed has increased in the last few years—from not being taken into account at all in 2014 to being used to match your products with search queries in 2021.
The value of a description is all the long tail words that can be used to match the product with search queries.
For optimization tactics, there are two:
Whatever you do, don’t waste time writing descriptions manually for your Shopping feed.
As the product type comes from your backend, it is ideal if any errors are fixed there first. But if you don’t have access, can’t get permission, or can’t fix the data in the backend for whatever reason, just use your favorite feed optimization tool (see the last section in this article).
There isn’t a correct way to add product types to your feed, and how you do it has no impact on how Google rates your feed. It is solely for you to better structure your campaigns, perform bidding, and analyze performance.
My preferred recommendation is to create levels of product types as follows:
Level 1 > Level 2 > Level 3
Electronics > Cables > Lightning charging cables
This enables you to:
There isn’t one right way to do this, and you can choose between two levels:
Level 1 > Level 2
Or five levels:
Level 1 > Level 2 > Level 3 > Level 4 > Level 5
A few tips:
Be consistent in levels across all products:But don’t feel limited by this. Some categories simply only have two levels.
Verify that products are in the right category: Some e-commerce platforms put products in multiple categories. Avoid this, and clean it up if necessary.
Clean up your product types: If you have duplicate, or very similar, product types (like plural/singular or dining table/dinner table), make sure you combine them.
Add more levels: If you have 1000 products with just one level of product type (like Supplements), add more levels. Again, ideally, you can get this data from your backend, but you might be able to find, for example, patterns in the links or words used in the title or description that will allow you to create rules for what product type to add.
Bonus tip (advanced): If you can’t populate the product type attribute as you want it straight from your e-commerce store, you can choose to do it in your feed optimization tool of choice.
And this is where it gets advanced … When you send your feed directly to the Merchant Center, you can’t add extra attributes. You can only send the attributes Google accepts.
But when you use a feed optimization tool, you can send nonstandard attributes. You can use these to build custom labels, product types, and titles.
Let me give you an example.
A client of mine was a store that sells training equipment and diet supplements. Overall, the Shopping campaign was running well at 3.5x returns.
However, when we started diving deep into the performance, it was clear that the supplements had 35% of the spend but only accounted for 5% of the revenue.
It was impossible to identify this initially because the supplements were split into 24 different product types without a first product type called Supplements. The data for the supplements as a category wasn’t accrued, so drawing the connection above was impossible.
What we did, and always do, was create main categories for all the product types. Every single product_type for dietary supplements was placed under the main product type Dietary Supplements. Each product also kept its original product type.
Original: Vitamin D
Optimized: Dietary Supplements > Vitamin D
With this setup, it was easy to see how the dietary supplement category performed as a whole and take necessary action.
Custom labels have no impact on how Google rates your feed. They are solely for you to better structure your campaigns, perform bidding, and analyze performance.
A custom label is just what it sounds like, and it can be anything you like.
Custom labels can be used for two things:
Structuring campaigns means you can split your campaigns (or ad groups or product groups) based on a custom label across multiple brands, product types, or bestselling products.
Analyzing performance means using the Reports section of Google Ads to aggregate data by using a custom label across all products to, for example, identify patterns in how well a product converts based on its delivery time (or any other factor).
Some of the most common use cases for custom labels are:
Here is what you can use these for:
*Just note that it’s not always the product that consumers click on that they end up buying. Basket sizes, additional products, and so forth can wreak havoc on using margins as custom labels. Read more about this in our article on profit tracking.
Most advertisers ignore the Google product category or at least put less effort into it. It’s not uncommon to see advertisers just choose one main Google product category for their entire feed and let it stand like that.
I get it.
It can be frustrating to find the exact Google product category. For instance, there is only one combined category for paintings, posters, and overall visual art:
Home & Garden > Decor > Artwork > Posters, Prints, & Visual Artwork
But there is a category just for food and water dishes for bird cages:
Animals & Pet Supplies > Pet Supplies > Bird Supplies > Bird Cage Accessories > Bird Cage Food & Water Dishes
So it’s hard to know when you’ve really found the most relevant Google product category.
As Google moves further away from keyword matching in the product titles and using other fields to determine how products should show, Google product categories (alongside all other fields) will continue to grow in importance.
The more ways you can tell Google about what your product is, the more opportunities you’ll have to show your ads. If this hasn’t already been implemented, then I’m a believer that it will be in the future.
The best way I’ve found to consistently set the correct Google product categories is by creating bulk rules for matching product_types with Google product categories.
Once you’ve finished setting up all your product types properly, go through the following steps:
This way, you take advantage of the work that you’ve already done when it comes to the product types.
One thing that is frequently overlooked is cleaning the existing data in your feed. To date, I have still not received a standard feed from an e-commerce platform that was up to par. Honestly, it’s not necessarily the platform’s fault. Often, you find quite a few mistakes in the data itself.
Whether it’s the brand attribute being incorrect or five different ways of spelling the same category, there is always data to be cleaned.
Below are some of the most common examples of values that should be cleaned:
One of the easiest ways to clean the data is simply using ‘search and replace’ so that every time XYZ data is wrong, you replace it with the proper value.
A client of mine in Europe had written their product titles in English for years. This action stemmed from the products genuinely having English names, but it was still a problem.
To solve this, I established a large-scale program in which I translated all individual words from English to Danish. This resulted in a huge increase in search volume and revenue from Shopping:
It was easier for me to create these rules in Feedonomics than to ask the client to translate all their product titles. Of course, translating the product titles wasn’t the only thing we did, but over time, we were able to create a very nice lift in revenue.
I’ve written more extensively about what tools I regularly use for Google Ads, but I’ll list the three tools I recommend for Google Shopping Feed optimization in order of priority:
1) Channable: This tool has increased in importance for us here at SavvyRevenue in 2021 as it has become our primary tool for building feed-based Search ads. But before it could build feed-based Search ads, it was a feed optimization tool and still is today.
The functionality is super easy to understand, and if you need more complex rules, then it has that option as well. The only thing Channable doesn’t have is bulk upload of rules, which is one of three areas in which Feedonomics betters them (although Feedonomics is about 3x more expensive).
2) Feedonomics: Feedonomics is my current go-to tool. This way of working with feeds is much faster than anything I’ve ever tried.
It comes down to three things:
I have spoken with several advertisers who opted for paying Feedonomics $3,000/mo. or more for access to the platform. Please don’t do that.
Now, we use Feedonomics because we do a lot of feed work, and we can make up the high price of Feedonomics because it saves us time. And as consultants that aren’t priced on how long a task takes us, for us, the tool’s efficiency is a clincher.
3) DataFeedWatch: I recommend DataFeedWatch to everyone who wants to get started with feed optimization as it has a very low learning curve. The tool is solid, and the constant improvements to the interface are quickly improving its standing in my toolbox.
As you walk away from this article, I hope you’ll walk away with this: feed quality is only increasing in importance.
As Smart Shopping (soon to be Performance Max) continues to take over in many accounts, one aspect that will provide you with an edge over your competition is the quality of your feed.
You are all running Smart Shopping, which means that you have no competitive advantage other than the feed. So you should probably spend some time improving it!
