Advertising is moving inside the shop

For years, online advertising lived in a separate place from the shop itself: banners on news sites, sponsored posts on social networks, search ads at the top of a results page. That separation is dissolving. Large delivery and grocery platforms are now turning their own storefronts into advertising space, using purchase and browsing data to decide which message a shopper sees and when. The trend has a name — retail media — and it is quietly changing the rules for anyone who sells online in Catalonia and across Spain.

The logic behind it is simple. A shopper who is already filling a basket is closer to a decision than someone scrolling a social feed. Advertising placed at that exact moment, informed by what the shopper has bought before, tends to be more relevant and easier to measure. Platforms can now connect the money a brand spends with the products that end up in the basket, which is precisely what advertisers have always wanted and rarely had.

Why this matters for a small or mid-sized shop

You may not operate a delivery marketplace with hundreds of thousands of partner outlets, and you do not need to. What matters is the underlying shift in expectations. Shoppers are getting used to recommendations that feel personal, to search results that anticipate what they want, and to a journey where the shop seems to know them. When they land on your PrestaShop or WooCommerce store, they compare it — often unconsciously — with the smoothest experience they had this week.

That raises the bar in three concrete areas:

Relevance. Generic homepages and one-size-fits-all product grids feel dated. Category pages, search and cross-sell blocks need to respond to what the visitor has actually looked at.
Measurement. If a large platform can tell a brand which orders came from which impression, your shop should at least know which channels, campaigns and pages drive revenue. Without that, every euro of marketing spend is a guess.
Speed and trust. Personalisation is worthless if the page takes four seconds to load or the checkout asks for the same data twice.

The data question: useful, but handled carefully

Personalisation runs on data, and in Spain that means GDPR compliance is not optional. The good news is that you do not need vast datasets to improve conversion. First-party signals — what a customer bought, which categories they browse, whether they abandon a cart — are usually enough to power sensible recommendations. What you do need is a clear lawful basis for processing, transparent consent where required, and a data map that tells you where information lives.

A practical approach for a Catalan retailer is to start small: instrument the events that matter (product view, add to cart, checkout start, purchase), store them in a way that respects consent choices, and only then layer personalisation on top. Doing it in that order avoids the common trap of building clever features on top of data you cannot legally or reliably use.

What a well-built store looks like in 2026

The technical foundations have not changed as much as the marketing around them suggests. A store that converts still needs fast hosting close to its audience, a clean product catalogue with consistent attributes, structured data that search engines can read, and a checkout with as few steps as possible. What has changed is the layer above: automation that segments customers, feeds that reach the right channels, and analytics that connect advertising to orders.

On PrestaShop and WooCommerce, much of this is achievable without rebuilding from scratch. Modules and plugins can handle abandoned-cart recovery, product recommendations, consent management and feed generation. The work that pays off is the integration — making sure the shop, the analytics, the email platform and the ad accounts all describe the same customer in the same way. Fragmented data is the most common reason a promising campaign fails to show a return.

Practical steps you can take this quarter

Audit your product data: titles, descriptions, categories, stock and prices should be consistent everywhere they appear.
Set up proper ecommerce tracking with consent-aware tagging, and review it monthly rather than once a year.
Test one personalisation feature at a time — a related-products block, a returning-customer homepage — and measure the effect on conversion rate, not just clicks.
Review your checkout on a mid-range Android phone over mobile data, which is how a large share of shoppers in Lleida, Tarragona, Girona and Barcelona will actually see it.
Document your data flows so that any future integration, or any request from a customer, can be answered quickly.

The takeaway

Retail media and AI-driven advertising are not a threat to independent online shops; they are a reminder of what shoppers now expect. The stores that hold their ground are the ones with clean data, fast pages and a measurement setup that tells the truth. Get those foundations right and the clever features become an advantage rather than a distraction.
