Bring back shoppers who viewed a product or left it in their cart. AdNabu places the Google Ads tag across your store, links Merchant Center, and builds your audience lists, so your ads can show the exact items each visitor browsed.
On most Shopify stores, retargeting gaps come from how the tag is set up rather than from the ads themselves. Here is where they usually show up:
Without a tag on every page, Google Ads generally cannot tell who browsed your store, which products they viewed, or how far they got.
A shopper who looked at one pair of shoes may see the same broad brand ad as everyone else, which tends to feel less relevant than the exact item.
Dynamic ads pull products from Google Merchant Center. When the IDs in the tag differ from the ones in your feed, Google usually cannot pair a visit with the right product.
Splitting visitors, cart abandoners, and past buyers in Google Ads takes time, and a missed exclusion can show cart reminders to people who already paid.
AdNabu's Google Ads Retargeting Pixel takes care of the tag, the product ID matching, and the audience lists, so you can spend your time on the ads themselves.
A retargeting pixel, also called a remarketing tag, is a small script that runs on your store pages and tells Google Ads who visited and what they did. Google groups those visitors into audience lists, and your campaigns can then show ads to people who already know your store.
Dynamic ads go a step further by featuring the product itself. The tag sends a product ID with each visit, and Google looks up that ID in Merchant Center to fetch the product details and images for the ad. If the ID in the tag and the ID in your feed follow different patterns, the match generally fails.
Remarketing tag: Fires on each page a shopper opens and records product views, cart activity, and purchases along with the product IDs involved. AdNabu places it across your store with the parameters Google expects.
Merchant Center feed: Holds the product data Google pulls into each ad. Newly added products can take around 24 to 72 hours to become available, so a fresh listing may not appear in ads right away.
Product IDs often look like shopify_US_6856369832023_40112111124567 or 6856369832023_40112111124567, depending on how your feed was created. If you are unsure which pattern your store uses, compare an ID in Merchant Center with the product link in Shopify, since both usually share the same product and variant numbers.
Right after you install the app, it asks which type of retargeting you want. Standard retargeting shows the same reminder ad to everyone in an audience, while dynamic retargeting, the recommended option, builds each ad around what that shopper did on your store. Here is how the two compare:
Standard retargeting is usually enough when a general brand reminder is the goal. Stores with larger catalogs typically see more value from dynamic ads, because each one can feature the item a shopper already showed interest in.
Everything happens inside the app. Here is the full setup:
Pick Standard retargeting to remind past visitors about your brand with the same ads, or Dynamic retargeting (recommended) to show each shopper the exact products they viewed.
Sign in with the Google account that manages your ads, then select your Merchant Center account and the feed label (data source) that holds your products. Standard retargeting only needs the Google Ads account.
Click Continue and the app creates the retargeting pixel for your website, places the tags across your store, and builds audiences in Google Ads from your products and collections.
Audience lists usually take 24 to 48 hours to show visitor data in Google Ads, so a zero count on day one is expected. The app does not launch campaigns for you, so add the AdNabu audiences to your display, search, or shopping campaigns once they start filling up.
Bottom line: Pick a retargeting type, connect your accounts, and the app handles the pixel and the audiences for you.
The app creates lists such as All Visitors, Cart Visitors, and Purchase Visitors in Google Ads. Here is how merchants typically use them.
Pair Cart Visitors with Purchase Visitors as a negative audience to keep this ad group focused on unfinished orders.
Add All Visitors and exclude Cart Visitors to reach people who viewed products but never added one to the cart.
Use Purchase Visitors to invite buyers back for a repeat order or a product that pairs well with their first one.
Add the lists to search ad groups for bidding or targeting, so you can adjust bids or narrow your reach when past visitors search again.
Show Shopping ads to people who already visited your store as they search for your products on Google.
Add the audience segments to display campaigns or ad groups to keep your products in view as past visitors browse other sites.
