Retargeting: How a successful strategy works

Why do adverts for products you’ve previously viewed often appear whilst you’re browsing the internet? This is no coincidence, but the result of a targeted retargeting strategy. This marketing tool is crucial for reaching potential customers again and increasing the likelihood of a purchase. Studies show that retargeting can increase the conversion rate by up to 150 per cent.

But how exactly does retargeting work, and how can you develop a strategy that is effective without coming across as intrusive? This article explains the mechanisms involved, outlines effective tactics and shows how to address the challenges surrounding data protection.

How does retargeting work? A look behind the scenes

Retargeting, also known as remarketing, is a form of online marketing aimed at people who have already interacted with a brand – for example, by visiting a website, viewing a product or subscribing to a newsletter. The aim is to target these users again with advertising messages as they continue their online activities.

The process can be explained in four steps:

• User tag: When you visit the website, a small code snippet – often referred to as a pixel or cookie – is placed in your browser. This snippet anonymously identifies you without storing any personal data.

• Recording behaviour: The cookie records which pages or products have been viewed. If the user leaves the website without carrying out a desired action (e.g. a purchase), the cookie remains active.

• Another address: When you subsequently visit other websites that are part of the same advertising network (such as the Google Display Network or Facebook), the system recognises this tag.

• Display of the advert: Based on the stored information, a personalised advert is displayed – for example, for the product the user has previously viewed.

This principle serves as a reminder of the brand and encourages users to return to the website and, if necessary, complete the desired action after all. The click-through rate (CTR) for retargeting adverts averages 0.7 per cent, which is around ten times higher than that of standard display adverts.

The benefits of a targeted retargeting strategy

A well-thought-out retargeting strategy offers much more than just a second chance; it provides a key lever for improving marketing efficiency.

• Higher conversion rates: The approach is aimed at target groups who have already shown an interest in the offer. This makes it much more likely that a sale will be made.

• Increased brand visibility: The brand remains in the minds of potential customers and helps to build trust and brand recognition.

• Precise targeting of specific audiences: Advertisements are not distributed widely, but are targeted at users whose behaviour suggests they have a specific need. This reduces wastage and optimises the advertising budget.

• Support for the purchasing process: Particularly for products with longer decision-making cycles, retargeting can accompany customers at every stage of their journey and provide relevant information.

Effective tactics for a successful retargeting strategy

Not every website visit is the same. A successful retargeting strategy therefore relies on precise segmentation of the target audiences.

Target audience segmentation

The messages should be tailored to the respective stage of the customer journey. People who have simply visited the homepage require different information to those who have added a product to their basket but then abandoned their purchase. Segments can, for example, be created based on:

• Product categories viewed

• Interactions (e.g. watching a video, starting a form)

• Stage in the purchasing process (shopping basket abandoners, returning visitors)

Dynamic retargeting

With this tactic, advertising messages are automatically tailored to the behaviour of the target audience. Anyone who has viewed a particular pair of running shoes will be shown exactly those shoes in the advert. This significantly increases the relevance of the advert and the likelihood of it being clicked on.

Delayed retargeting

Users are addressed differently depending on when they last visited the site. Someone who visited the site just 3 days ago will receive a different message to someone whose visit was 30 days ago. This helps to maintain interest without coming across as intrusive.

Best practices: How to optimise campaigns

Proper implementation is crucial to the success of a retargeting strategy. The following points should be borne in mind to get the most out of your campaigns:

• Exclude converted users: It is not particularly effective to display adverts for products that have already been purchased. Users who have converted should be excluded from ongoing campaigns in order to save on budgets and ensure a positive user experience.

• Using frequency capping: The frequency of ad impressions per person should be limited to avoid ‘banner blindness’ or the impression that the ad is intrusive. A figure of 3–4 impressions per day per person is considered a good guideline.

• Testing and varying adverts: Monotony should be avoided. Different visuals, copy and calls to action should be compared in regular A/B tests to achieve the best performance.

• Don’t forget branding: The brand should remain clearly recognisable in all adverts. The logo and colour scheme must be used consistently to ensure brand recognition.

The Challenges and Future of Retargeting

Although retargeting is highly effective, the growing focus on data protection and scepticism towards tracking technologies pose major challenges.

Privacy and Cookie Policy

Stricter data protection regulations such as the GDPR and the phasing out of third-party cookies in popular browsers are making traditional retargeting more difficult. It is important to obtain consent for data collection and to provide transparent information about how the data is used.

Negative perception

Many users find retargeting adverts too intrusive or feel as though they are being ‘followed’. An overly aggressive approach can ultimately damage the brand’s image.

Possible solutions for the future

To meet these challenges, we need to adapt:

• Using first-party data: Using your own data sources, such as newsletter subscriptions or customer accounts, means you are not reliant on third-party cookies.

• Contextual advertising: Advertisements are placed in contextually relevant environments; they are no longer targeted purely on an individual basis.

• Content marketing: Organic traffic generated by high-quality content expands the data protection-compliant retargeting pool.

• Lookalike Audiences: Platforms such as Facebook and Google make it possible to reach new user groups with characteristics similar to those of the existing customer base.

Conclusion: Retargeting remains an effective tool

Retargeting remains one of the most effective methods in online marketing for strengthening brand presence and boosting sales. The key lies in a well-thought-out strategy that focuses on users’ needs.

With targeted segmentation, creative adverts and compliance with data protection guidelines, retargeting becomes a service that delivers added value. Those who adapt their strategy to new circumstances secure a competitive edge and foster long-term trust.
