In part one of this series we covered setting up Google product feeds. In part two we covered setting up Product Listing Ads in AdWords. In part three we covered properly tracking product search performance. In this post we will cover optimizing product feeds, product listing ads, and product extensions.
Optimizing Product Search
One of the great things about Google’s Product Listing Ads is that there is less to optimize than with traditional AdWords ads. You don’t have to choose specific keywords or even write ads; you just have to set up your feed properly, choose good images, have well-written titles and descriptions, keep the feed up to date, and build a negative keyword list.
One of the terrible things about Google’s Product Listing Ads is that there is less to optimize than with traditional AdWords ads. ;) We’re used to having a lot of control (or feeling like we have a lot of control) over our paid search marketing results. With product search we lose some of that control and put Google in the driver’s seat.
With PLA, you do not (currently) need to worry about:
- Display Network results – PLA are only on Google.com and some search partners
- Mobile targeting – PLA are only displayed to computer users
- Ad delivery – Accelerated delivery is not supported with PLA
- Ad rotation – You aren’t writing and optimizing ads
Right about now you’re probably thinking, “so what can I optimize?” There’s quite a bit you can do to ensure your product search campaigns are successful. The image below is a great example of what can happen if you don’t optimize your campaigns and feeds properly.

Someone specifically searching for a red cocktail dress shouldn't be shown an ad with a picture of a black dress.
Feed and Ad Optimization
You need to approach product feed optimization much like you would website optimization, including utilizing keyword research and imagery changes, with a focus on the following attributes:
Product_type Attribute
This attribute within your product feed allows you to indicate how your product should be classified. This classification will probably closely match how you organize products on your website. For instance, if you were selling a red cocktail dress, this attribute may be Clothing > Women’s Clothing > Dresses > Cocktail Dresses.
When choosing the wording used in this attribute, you will want to do some keyword research to determine the best words to use. For instance, in the example given above, you would research whether it was best to use ‘women’s clothing’, ‘women’s clothes’, or ‘women’s apparel’. You want to choose the wording that has the most potential traffic but with the least competition.
Title and Description Attributes
The text you put in the title attribute will be shown on the general search results page, as shown below, as well as on the Shopping results page. The description will also be shown on the Shopping results page. These attributes should be researched, written, and optimized on an ongoing basis.
In the example shown below, the titles are not eye catching and only one uses the phrase “red cocktail dress” specifically. The second result even says “holiday red” but we’re definitely not in holiday red dress shopping season. Optimize your product feed titles and descriptions to increase CTR using the same tactics you do for ad text and SEO page titles and descriptions.

Write titles that make people want to click.
Additionally, you may want to change your titles and descriptions to capitalize on trends, holidays, or current events. For instance, leading up to holidays you may want to include the word gift in your titles and descriptions. Or, if you sell a product that was featured in a movie or television show, you should update your feed to say “as seen in <insert show>.” Finding and maximizing competitive advantages is a key to success in Shopping results.
Image Attribute
The image you choose can make or break your campaign performance. Make sure you are using images that display the exact product users are searching for, down to the color. If you are selling a product that other websites sell, make sure you use images that are unique to set your site apart from the competition. Finally, test different images and see what works best. Rotating and testing images in your product feed is the equivalent of testing new ad copy in your regular PPC ads, and should be made a priority.
Negative Keywords
Negative keywords in PLA campaigns work the same as in regular search campaigns. Using keyword research, common sense, and data you’ve gathered from other marketing efforts, you should build a robust negative keyword list to prevent your PLA from showing on unwanted searches.
Continuing with the red dress theme, the seller of this dress may have campaign-level negatives such as ‘bridesmaid’ and ‘prom’ to prevent their ad from showing if someone were to search red bridesmaid dress or red prom dress. They may also want to have ad group-level negatives with more specific features such as dress length, sleeve length, or neckline type. Getting this granular with negatives can be tedious but will pay off in the end with higher click through and conversion rates.
Bids
Bids for PLA should be optimized in the same way that you optimize bids for regular PPC campaigns. Experiment with increased bids for additional traffic or decreased bids to increase return on ad spend.
Test, Test, Test
To properly optimize your feed, you will need to test changes one at a time to see which strategy is the most effective. You don’t want to test image and title changes at the same time because you won’t know which change is responsible for the change in performance. You may also have thousands of products in your feed to optimize, so testing feed optimization can be a tedious and time consuming task. But, regularly updating your feed and properly optimizing attributes will result in increased sales.
Tip: Create a schedule in your calendar for feed optimization to ensure you stay on track and to break the project into manageable chunks so you don’t feel overwhelmed.

Do you have any feed optimization tips or shortcuts to make the process easier? Share them in the comments below!

That was great Pamela! <> is a great tip and a good reminder that you DO NOT need to use your default product name/title.
Thanks Kristi! Optimize, optimize, optimize! :)
Images are central to product listings because consumers only have them for reference when making purchases online. Business owners should make sure their images are optimized.
Great Pamela very nice tips and certainly I will work on your suggestions. I was looking to get some tips to launch some products through google and its been a great advice.
Thanks for sharing the post!
Thank you Ayaz. Best of luck with your feed!
Thanks so much Pamela, I already suggested setting up a Google Product feed to a client to with a rather popular online store, but I never thought about Product listing ads.
Its really pain to create xml feeds but got some tool to create. The easiest way we can do is from updating in excel. where it fetches all the feeds. Great info… Not many are talking about this when it comes for ecommerce seo.
Agreed! Thanks man.
A bit late on the reply but you could write your XML within excel and save the page that way, though long term the XML feed is easier to update. One to add as soon as you have a good website backend.
Why not just use Google AdWords instead? What are the advantages of Product listing ads? Do you have anu references of how to set the non paid product listings?
HI Jake – product listing ads are Google AdWords. They are just another type of ad. View the first post in this series to see why you should use them.
Pamela,
Thanks for yet another great post on the topic of product feeds. I’ve really enjoyed reading these as there isn’t a whole lot of info online about the subject. I think my favorite tip in this post is “These attributes should be researched, written, and optimized on an ongoing basis.” Its far too easy to just set it and forget it, when you could be testing and tweaking constantly to push revenues higher and higher.
Thanks Greg! ABO (always be optimizing)!
Agreed, well done Pamela.
The more research you do about the user search, the more likely you are to show up for searches which match user intent. I think another aspect would be to try and isolate long tail searches, for shoppers who are further down the conversion funnel.
Other than just searching terms, are there any techniques your recommend retailers user to pinpoint and refine PLA’s (In terms of classification and product information)?
Merry – You are right about long tail searches. Optimizing product feeds for those can be very lucrative. Especially because many aren’t doing it.
Doing full keyword research and competitor research is the best way to build your ideal keyword list. Use tools like spyfu to see what your competitors are doing, and your favorite keyword research tool to find the highest volume keywords with the least competition.
I’m not sure you understood my question Pamela.
PLAs aren’t based on bids for Keywords, but for specific products and product categories. Keyword research would be helpful for a general AdWords campaign, but that doesn’t apply to PLAs.
Yes, I understood your question. You need to do keyword research to write product titles, descriptions, etc to optimize your feed to run on the keywords you want your ads to appear on.
Many useful tips Pamela, thank you. What role do user reviews play in improving overall product search performance?
The million dollar question :) Right now there isn’t much information on that but with the recent introduction of Google Trusted Stores, I think we’re looking at a future that includes user experience as a factor.
Well I’ve been through your 4 part Blog. I’ve set up a couple of PLA Campaigns with AdGroups Unfortunately creating a very specific AdGroup, say for a specific collection of products from a specific Brand, really doesn’t help (what am i missing!). Because of the attributes we can select, “Brand” and then we can select the “product type” attribute, but that’s just Google’s Taxonomy, so there’s no way to really control costs by narrowing down to a specific collection or even a specific product. So really we’re just spending $ on what G feels like throwing up there and we have no control over what they display-and we can’t even tell what triggered the PLA to appear. I gotta be missin something!!
Hi Todd – I’m sorry this has been a frustrating experience for you. Unfortunately I can’t really provide much more guidance without looking in your account, much like a mechanic can’t fix your car over the phone :) It’s probably time for you to get in contact with someone who has been through this before and can get everything working properly for you.
Thank you,
Pam
I have integrated Google merchant center & Google Adwords. There is default ad in Product Listing Ads campaign. Today, I have added 50+ sectional sofas on my website. I want to display my sofas on first page during exact match keywords sectional sofas and leather sofas. So, How can I get it done?
Hi Hiren – You can’t control which keywords you are matched for with PLA as closely as you can with regular keyword campaigns. To ensure your ads are shown at the top of the page for [sectional sofas] and [leather sofas] I would also create a regular search campaign with those exact match keywords and regular text ads. You could also add product extensions to this campaign to add your product data to the ads. By using both regular keywords and PLA ads you will have a better chance of covering all the bases with your keywords.
What are “product type” used for? They’re in the “target” for PLA’s??
Todd – That is how to select which products should be shown in which ad group. This post discusses how to set up your PLA campaigns.
Thanks for the quick repsonse!
What field in the Data Feed is “Product Type” matched to? The Targets “Brand” and “Condition” have matched and Google validates those easily. We can’t seem to get a “validation” for the “Product Type” target.
The Product Type attribute in the feed. Your entry in AdWords has to match it exactly to validate.
Ok, that’s what we thought, but it doesn’t seem to validate.
We used this Field to create our own custom taxonomy.
An example is shown below:
Brand Name>Collection Name>Part# (obviously using actual names and #’s)
Are we doing this incorrectly?
It looks okay here but I can’t be sure without looking in the account. Try setting it up with just one level (like brand name) and see if it validates. If it does, expand to two levels (brand name > collection name) and try again. This will help you pinpoint where the issue is.
DUH! Why didn’t I think of that??! Thanks for the great idea, I’ll give it a shot.
I am so glad I found your series on this! I was having a hard time understanding what a product listing ad actually was. You have explained everything so it is understandable to someone still on the learning curve.
I have to admit though, that I got totally lost in part#3. I hope if I read it several times it will sink in. Thanks again.
Thank so much for these 4 posts – I have already read twice and am now working through comments – absolutely invaluable post for using Google product ads
One question I am getting the following validation when defining my product id
“Validation using ID attribute is not currently available.” is this a problem with my feed? (I’m in the UK if that has any influence on the validation
Richard, I’m getting that issue here too! (I’m also in the UK, and use Shopify).
Kinda frustrating as there isn’t much info on that particular error. I’m trying to split up my PLA’s for better results…
Hi Matt
I ignored the validation error and set up an ad with it – at first nothing but its now receiving traffic – teething problems maybe? An going to try it on a few others. Let me know how you get on – its always good to share experiences on this type of thing – especially with google moving the goalposts every month, week, day!!
Thanks Richard, I’ll try it by ignoring the error as you say…
I was able to segment my products into Ad Groups based on the Product Type, so at least I have some control. Have you seen the search terms report for PLA’s yet? It’s handy to see what terms convert for certain products. Yes, keep in touch!
