Google Shopping Ads for ecommerce stores



Have you already used Google Shopping Ads for advertising your products? If so you are aware that Shopping Campaigns work great for ecommerce companies! If you haven’t used them yet or think you can still take more advantage of your Shopping campaigns, you are reading the right article! We will share with you great tricks for boosting your shopping ads performance.

If you are familiar with search campaigns, you probably know a lot about keyword-level bidding, but Shopping ads work different, you will need to understand how the Merchant Center works!

How to use the Merchant Center for my Google Shopping Ads?


For creating your Google Shopping Ads you need to have the list of the products you sell and want to advertise in your Merchant Center. This list should be in a special format that works kind of a spreadsheet. You will have to list your product IDs, title, description, product category and type, availability status, product link, price, etc. Google use all this data for matching your product to related search queries.

Your Google Shopping Ads will be built with this data and information you have in the Merchant Center. No need to write your ads per product as you do for search campaigns. Easier, right? But there is something you have to think about, your merchant center should always be updated or your Google Shopping Ads won’t be running. You keep your data feed updated manually, by hiring someone or using a software.

Key tricks for your product feed:

  • If it’s your first time using Google Shopping, start first with a few of your high-margin products so you learn how it works before creating Google Shopping Ads for all your products.


  • Google is especially sensitive about pricing, if the price in your product feed doesn’t match the one in your store, your ads won’t show up! Take special care of this if you deal with international currencies.


  • Revise all your URLs, so they don’t end up in 404s pages. Dead-linked images won’t show your products!


  • If you advertise in different countries, create a data feed for each country. Google Ads campaigns are built per country.


  • Google Shopping Campaigns allow you add negative keywords to cut unwanted traffic to your Google Shopping Ads, do it! But be careful not to cut all your traffic.


  • Your product images should be high-quality! This is really important, they cannot be edited, watermarked, confusing or pixelated. Images should only include the product you want to advertise. The wrong images could break your ads.

Then, how do I create my Google Shopping Ads?


If you have your product data feed ready and your Merchant Center linked to your Google Ads account, it’s time for creating your Google Shopping Ads! And it’s really easy, you will just need to choose the product feed you want from your Merchant Center and a sales country.

Once you have your campaign created, organize your ad groups! How you organize them really depends on the size of your company and the  number of products you sell. If you have few products, you will probably just need one ad group, otherwise you can split your products by category, brand, type, etc.

Once you have organized everything, it’s time to take important decisions about your bidding in the different product ads.

Choosing the right bidding strategy for my Google Shopping Ads.


Google Shopping Ads don’t work with keywords, so what do you think you’ll bid on? You’ll bid on your own products! You can set bids on each of your products, or on groups of products. Each of your products will probably have a different margin for you, so it would  make sense to raise your bids for the products with a higher margin.

Most ecommerce owners group their products by category and then by its margin. If there are products that don’t belong to any of the groups you’ve made, they’ll go to an “everything else” group that Google create automatically. However, it can become really confusing, so we will give you some tips:

  • If you have less than around 200 products, bid by individual product. Do a first segmentation by category, type or brand and then segment by product ID.


  • When having a lot of products, do the first segmentation according to the way you have your store organized. Then segment by similar profit margin products. Take into account that Google’s consideration of your product relevant or not for an specific search query won’t be influenced by the segmentation you make.


  • For taking bidding decisions, focus on your ROI. Check how much you can afford to spend on Google Shopping Ads for each product or product group.


  • Set lower bids than you would set for your search campaigns, and even a lower one in the “everything else” group.


  • Take into account that changing a bid in your Google Shopping Ads might have immediate effect on the performance of your ads.


  • An important piece of advice is: advertise your special promotions in your Shopping Ads! This will help you differentiate from the competitors that are advertised next to you!


  • For monitoring your Google Shopping Ads performance, the best metric you should look at is your Cost per Conversion. The Search Impression Share metric also gives you a good sense of how much potential your products have to grow.


  • Once you have run your Google Shopping Ads for a while, separate your “best sellers” and treat them individually, create their own campaigns or ad groups. These products are bringing you most of the money, so it’s worth it to have them controlled.


  • Another thing to do when you have already observed the performance of your Google Shopping Ads for a while, is segmenting your bidding strategy by location. Bid more for the regions that are bringing you more value and traffic. Perform the same type of segmentation with device type, gender and age.

Applying all the previous tricks and tips on your Google Shopping Ads, will get you prepared for succeeding! Now you are ready for starting your first Google Shopping Ads.
