Dynamic Remarketing | Show the Product They Viewed
Dynamic remarketing shows a visitor the exact product they looked at, rather than a generic brand ad. It is the personalised version of classic remarketing.
Why it is stronger
A generic reminder ad says “we exist”; a dynamic ad says “the product you looked at is here”. The second is a far closer message for someone at the decision stage.
On sites with large catalogues the gap widens further: remembering which of hundreds of products they viewed is not easy for the user either, and the ad does that remembering for them.
Two things it needs to work
First, a product feed. The image, price and title shown in the ad come from the Merchant Center feed; if the feed is incomplete, so is the ad.
Second, a correctly built audience tag. The site has to tell the advertising side which product was viewed and at what stage — viewed, or added to cart. That information comes from the e-commerce measurement setup.
The most common problem: ID mismatch
The campaign is built, the audience fills, but ads come out empty or show the wrong product. The cause is almost always the same: the product ID sent by the site does not match the ID in the feed.
When the two systems know the same product by different names, no match can be made. After setup I always test with a few products: viewing one on the site and confirming it appears in the ad is the only proof the setup genuinely works.
Separating audiences and messages
Someone who viewed a product and left is not the same as someone who added it to cart and abandoned. The second is far closer to buying and deserves a different message.
Excluding existing customers applies here too: showing the same product to someone who already bought it wastes budget and creates a poor experience. Frequency capping and audience duration should be set as in classic remarketing — unlimited following turns a reminder into an irritation.
How do we start? First I check whether the product IDs your site sends match those in your feed. I send the setup plan and audience split in writing. You can reach me from the contact page.
Frequently Asked Questions
Can dynamic remarketing work for a service business?
The feed concept can be adapted to services, but in practice classic remarketing is enough for most service businesses. Setup cost can exceed the return.
Doesn’t Performance Max already do this?
PMax uses dynamic remarketing inventory too, but you do not control it. If you want to manage the audience and message split yourself, a separate campaign is more transparent.
Don’t users find it intrusive?
They do when no limits are set. With frequency capping, a sensible audience duration and excluding purchasers, complaints almost entirely disappear.
