Case Study | E-commerce


KLEIR. is a clothing label with a love for the dialect of Antwerp city. It is pure passion for Antwerp, its inhabitants, and its language. The products are fair and responsible, which is why they are made entirely or partially from organic cotton and carry the label of the Fair Wear Foundation. On the webshop, you can buy sweaters, T-shirts, baby rompers, or accessories with the funniest Antwerp quotes. It’s a great way to stay original and authentic.

KLEIR. approached boostU to increase its online sales through targeted digital marketing.

Increasing Online Sales with Targeted Google Ads and Facebook Campaigns

Google ads

To start, we utilized Google Ads campaigns to enhance KLEIR.’s online presence and attract more visitors to the website to increase conversions. In addition to generic search campaigns, we also launched shopping campaigns targeting everyone in Flanders looking for clothing with Antwerp quotes.

Facebook & Pinterest

Next, we set up Facebook and Pinterest campaigns to reach potential customers through social media. Here, we targeted everyone in Flanders interested in both adult and children’s clothing with Antwerp quotes. To make the campaign more attractive to the target audience, we also used dynamic ads to show specific products that match the potential customers’ interests.

Increasing website visitors & online Sales 

The result of our digital marketing campaigns are very successful. We see a significant increase in website visitors and online sales. Google Ads led to more than 900,000 impressions and 21,000 clicks to the website. The Google Ads campaigns also generated 500 conversions at a cost per conversion of only €13. With the Facebook and Pinterest campaigns, we reached over 4 million people and generated over 7,000 clicks to the website. With the social campaigns, we also achieved a ROAS of 5.

In conclusion, the combination of Google Ads and social campaigns helped KLEIR. increase its online sales and create more awareness for their products among a relevant audience. By targeting and displaying relevant ads, we maximized the given marketing budget.
