What is Retargeting?
Retargeting (also remarketing) shows ads specifically to people who have already visited your website - visitors to a product page who did not buy, or basket abandoners. Technically this works via cookies or ad-platform pixels: the visit is tagged, and the platform (Google, Meta, LinkedIn) then serves your ads to that person elsewhere. The logic: someone who already knows you is easier to convince than a cold contact.
The technical foundation has been shifting for years: Safari and Firefox block third-party cookies by default, and tracking protection plus consent requirements thin out the audiences. Retargeting is therefore moving towards owned data - customer lists, newsletter subscribers, logged-in users - and towards on-platform signals such as video views or profile visits that work without cookies.
In practice, dosage decides effectiveness: frequency caps against the feeling of being followed, time-limited audiences, different creatives per funnel stage. And an honest cost truth: retargeting does not fix a weak funnel - it only amplifies what already works on the website. If you have to buy back visitors at scale, you usually have a conversion problem, not a reach problem.
Why does Retargeting matter?
How fragile the technical base is was shown by Google’s U-turn: after years of announced cookie deprecation, the company officially declared in April 2025 that Chrome would keep third-party cookies after all - while Safari and Firefox have long blocked them. Anyone planning retargeting is planning on shifting ground and needs owned data as the foundation.
Retargeting in practice
- 01A B2B provider shows visitors of its pricing page who did not submit a form a case-study ad on LinkedIn for two weeks.
- 02An online shop reminds basket abandoners of the products they left behind via a Meta ad - with a frequency cap, so a reminder does not become stalking.
- 03A SaaS tool builds its retargeting audience from newsletter subscribers instead of cookie data - the list belongs to the company and survives every browser change.

- Attribution in 2026: what you can actually measure - and what you can'tYour dashboard says Google, your customer says podcast - and both mean the same enquiry. Attribution promises clarity about which channel sells, and in 2026 it mostly delivers one thing: a precise-looking number on shaky ground. This piece separates what you can genuinely measure from what merely looks measured.
- Chatbots vs. AI agents: what actually generates leads on your website35 per cent of German companies have a chatbot - but only 13 per cent have a real AI chatbot. Between those two numbers lies the difference between a click menu that frustrates visitors and an agent that qualifies enquiries while your team sleeps. Here is what the data says about both - and how to tell which one you are looking at.
