Retargeting

Retargeting is a form of online advertising where you show ads to people who have previously visited your website but did not take action. Using a tracking pixel, you register these visitors and place them in a target audience. You then display targeted ads via display networks or social media while they’re visiting other websites. The goal is to create repeated contact and encourage visitors to return so they can eventually convert. Retargeting works because, on average, people need multiple touchpoints before making a purchase or submitting an inquiry.

How retargeting works technically

Retargeting starts with a tracking pixel that you place on your website. This is a small piece of code that tracks visitors without storing any personally identifiable information. When someone views your product page or fills a shopping cart but doesn’t complete the purchase, that visitor is added to a target audience in your advertising platform. Platforms such as Google Ads, Meta Ads, or LinkedIn Campaign Manager use these target audiences to display ads while the visitor is browsing other websites or social media. You can segment audiences based on pages visited, time since the visit, or specific actions. For example, an ecommerce store can show different ads to someone who viewed a product versus someone who almost completed a purchase.

Why retargeting is more effective than cold acquisition

Visitors who are already familiar with your website convert more often than completely new visitors. They have already shown interest and built trust by browsing your site. Retargeting capitalizes on this warm audience. In practice, small and medium-sized businesses find that retargeting campaigns often have a lower cost per conversion than standard display or search ads. The mechanism works because repeated exposure to your brand increases brand recognition and reminds visitors of their original interest. This is particularly relevant for products or services with a longer decision-making cycle, such as B2B software or higher-priced purchases. However, the Dutch Data Protection Authority does impose requirements on the use of tracking cookies, so you need to obtain consent via a cookie banner.

What retargeting brings to SMBs

For an ecommerce store with 5,000 visitors per month of which 98% do not buy, retargeting offers a way to reach those 4,900 visitors again without having to actively search your site again. A local service provider can remind visitors who visited the contact page but did not fill out a form to request a quote. Retargeting fits within a broader SEO strategy and performance marketing approach. You measure results directly through conversions and can drive budgets based on return on ad spend. It does require ongoing management and creative variation to avoid ad fatigue. Combine retargeting with lead generation tactics for a complete acquisition process.

Retargeting can be used in different ways, depending on your business model and target audience. The technique works for both ecommerce stores and service providers, but the approach differs for each situation. Below are four concrete applications that have proven to be effective in SME practice.

Abandoned shopping cart campaigns for ecommerce stores

One of the most common retargeting applications is to recall visitors who put products in their cart but did not checkout. You create a target audience of everyone who reached the checkout page but did not proceed to purchase. Then you show ads with the exact product they left behind, possibly with a discount code or free shipping as an added incentive. For example, an ecommerce store in home decor can show an ad that says "Forgot to checkout? Order now with 10% off". This works because the intent was already high and you are only giving a final push. Do pay attention to timing: retargeting too soon can come across as intrusive, too late and the interest is gone. A window of 3 to 7 days often works well.

Content retargeting for lead nurturing at B2B service providers

B2B companies with a longer sales cycle use retargeting to keep visitors who read content warm. Say someone reads your blog article about process automation but doesn't request a quote. You can then show that visitor ads with a case study, a free scan or a webinar invitation. This reinforces your expertise and keeps your company top-of-mind while the prospect goes through his decision-making process internally. An automation agency might retarget visitors to an article on AI automation with an ad for a free process analysis. This approach works because you continue to add value rather than sell directly. Combine this with smart integrations between your Web site and CRM for automated follow-up.

Cross-sell and upsell after previous purchase

Retargeting is not just for non-buyers. You can also retarget customers who already made a purchase with additional products or services. A sports nutrition ecommerce store can show customers who bought protein powder ads for shakers or supplements. A software company can retarget basic subscription users with the benefits of a premium package. This approach has the advantage of working with a target audience that already has trust and is more likely to buy again. However, it is important to limit the frequency and stay relevant. Cross-selling too aggressively damages the customer relationship. Use conversion data to determine when someone is ready for the next step.

When retargeting is the right choice and when it is not

Retargeting works well if you already have sufficient website traffic (at least 1,000 unique visitors per month) and a clear conversion goal. It is less suitable if your product or service is a one-time, impulsive purchase with no thought time. Also, if your target audience is very small and local, retargeting can be inefficient due to insufficient volume. Don't use retargeting as a replacement for a poor website experience: if visitors drop out due to unclear information or a slow site, retargeting won't solve that. In that case, you're better off investing in web design and user experience. Retargeting is an enhancer of what is already working, not a repair of what is broken.
