Retargeting: Strategy and Psychology for Greater Impact

It's a technique that lets you reach users again after they've interacted with your brand in some way: they visited your website, viewed a product, added something to their cart and left (abandoned cart), or engaged with your content or emails.

Its goal is to remind them of your brand, guide them through their decision-making process, and maximize the chances of conversion.

At its core, retargeting tracks users through pixels and cookies. This involves:

1. Implementing pixels and cookies

Pixel placement: A small snippet of JavaScript code (a tracking pixel or tag) is installed on the website.

User tracking: When someone visits your site, the pixel places a cookie in their browser, anonymously tracking their behavior: pages visited, products viewed, engagement time, interactions, and more.

2. Audience segmentation and profiles

Behavioral data: The information collected is used to segment users based on their interactions: those who viewed a specific product category, added something to their cart, or consumed certain content.

Personalization: That data is used to build audience lists for ads tailored to the user's previous actions.

3. Distribution and advertising networks

Network integration: Ads are shown through Google Display Network, Facebook, Instagram, YouTube, and other programmatic placements.

Cross-channel: Users can see ads on social media, blogs, videos, and mobile apps, maintaining a consistent brand presence.

4. Types of retargeting

Static retargeting: Shows a generic ad to every user in a segment (example: a 10% off coupon for everyone who abandoned their cart).

Dynamic retargeting: Shows hyper-personalized ads based on the user's exact browsing history (example: the same TV they left in their cart, with free shipping).

5. Campaign optimization

Burn pixel: Excludes users who have already purchased to avoid ad fatigue and wasted ad spend.

Testing and adjustments: Ongoing testing of messaging, formats, frequency, and creative to maximize conversions and ROI.

In an advanced strategy, not all audiences are the same. We can work across different levels:

First-party lists: customer databases and email addresses collected at signup.

Users who engaged with previous ads.

Followers or people who engage with social media posts.

Users who watched videos.

People who specifically engaged with videos or forms.

Each level has a different value and requires tailored messaging, creating a more efficient retargeting funnel.

The familiarity effect explains why it works: the more we see something, the more we trust it.

It takes between 6 and 20 touchpoints for a consumer to take action (HubSpot, 2024).

Retargeting can increase conversions by up to 147% (99Firms, 2024).

70% of consumers are more likely to convert after being reached again (Cometly, 2025).

According to Baymard Institute (2024), nearly 70% of online purchases are abandoned before checkout is completed. Retargeting can:

Remind shoppers of the exact product.

Add urgency (“Only 3 left”).

Offer an incentive (a coupon or free shipping).

This can recover between 10% and 15% of sales that were considered lost.

Retargeting requires:

Precise technical setup of pixels, tags, and events.

Integration with multiple advertising platforms.

Smart segmentation to avoid wasted impressions.

Creative tailored to each stage of the funnel.

Constant monitoring for real-time adjustments.

Implementing retargeting campaigns involves using cookies and tracking technologies that collect browsing data.

Under regulations such as GDPR (EU) and CCPA (California), and as a transparency best practice, we recommend:

Displaying a clear, visible cookie notice.

Explaining which cookies are used (technical, analytics, marketing).

Allowing users to accept or reject cookies based on their preferences.

Including the use of data for retargeting in your privacy policy.

At Alterno Agency, we recommend implementing a Cookie Consent Manager that complies with regulations and ensures transparency and user trust.
