What is Criteo?
Criteo is a commerce media company that helps brands and retailers reach shoppers across the open web and on retailer websites. It is best known for retargeting, which shows people products they viewed, or similar items, after they leave a site. It also offers campaigns to find new customers and retail media for brands selling through retailers. Its ads are usually built dynamically from your product catalogue, so each shopper sees relevant items.
What does a Criteo agency do?
A Criteo agency plans, sets up and manages your campaigns. At Vertical that covers the product feed, audiences, creative, tracking, budgets, optimisation and reporting. Because we also run search, paid social, email and ecommerce websites, we plan Criteo as part of the whole customer journey rather than as a standalone channel. You work with senior people who understand both commerce media and your commercial goals, supported by AI agents that watch performance every day.
Is retargeting still worth it?
It can be, when it is run carefully. Many shoppers need more than one visit before they buy, and a timely reminder can help them come back. The risk is paying for sales that would have happened anyway, or showing ads so often that people get irritated. We set sensible windows and frequency limits, exclude recent buyers and use tests where possible, so retargeting is judged on the extra sales it brings rather than on every purchase it was near.
How important is the product feed for Criteo?
Very important. Criteo builds most of its ads from your catalogue, so the feed decides which products can be shown and how they look. Missing images, wrong prices, out-of-stock items or vague titles all hold performance back. We clean and structure the feed, keep it in sync with your store and add labels that let us prioritise products by margin, season or stock level. A good feed is often the quickest way to better Criteo results.
Can Criteo help us find new customers?
Yes. Alongside retargeting, Criteo can run campaigns aimed at people who have not visited your site yet but show similar shopping behaviour to your customers. We keep these separate from retargeting, so you can see clearly how many genuinely new customers they bring and at what cost. That makes it easier to decide how much budget to give acquisition versus bringing back existing visitors, and how Criteo compares with other prospecting channels.
What is retail media on Criteo?
Retail media lets brands advertise on retailer websites, for example through sponsored product placements and display ads, close to the moment people decide what to buy. Criteo works with a number of retailers to offer this. It suits brands that sell through those retailers and want to stay visible where their customers shop. We plan retail media alongside your direct channels, so budget and messages fit together rather than competing.
How do you measure Criteo performance?
We set up tracking properly and read Criteo results alongside your analytics and sales data. Because retargeting reaches people who may already be close to buying, we look beyond platform-reported sales to new customer rates, assisted conversions and, where possible, holdout tests that compare people who saw ads with people who did not. That gives a fairer view of what Criteo adds and helps us decide how much budget it deserves.
How much should we spend on Criteo?
It depends on your traffic, catalogue and goals. Retargeting budgets are naturally limited by how many people visit your site, while acquisition campaigns can scale further. We start with a level that lets us learn clearly, then adjust based on incremental results and margin rather than headline revenue. If spend could be working harder in another channel, we will say so, because the aim is growth across your whole marketing mix.
How do we get started with Vertical?
Start with a conversation about your store, your customers and the channels you already run. If you use Criteo today, we usually begin with an audit of your feed, audiences, creative, frequency and measurement, then share a prioritised plan. If you are considering it, we look at how it would fit alongside your other channels and scope a sensible first phase. Either way, we will give you a straight view of what we think it can do.
