Zazume Achieves 16% Lower Cost Per Acquisition Than Their Goal

Zazume Achieves 16% Lower Cost Per Acquisition Than Their Goal

Zazume needed to promote its services to property owners and renters in Madrid and Barcelona. They were already using search and social media platforms to run campaigns, but they were looking to decrease cost-peracquisition (CPA) and drive more high-quality leads to their signup forms.

Zazume partnered with Taboola to launch sponsored Image Ads across a network of premium publisher sites. While Image Ads typically contain a headline and image, Zazume bolstered its messaging with descriptions, which provide more information pre-click, and call-to-action (CTA) buttons, which prompt viewers to follow through to the brand’s landing page.

Post-click, users were taken to personalized landing pages with easy signup forms. These pages contained interactive features like a calculator for setting profitable rental prices, and a search tool for finding vetted tenants. Zazume also ran a separate campaign to promote insurance that protected property owners in case their tenants couldn’t pay rent.

By working with Taboola, Zazume achieved a 16% lower CPA than its goal, driving qualified leads to fill out its forms.

Taboola Drove Leads for Zazume of the Highest Quality, Surpassing Search and Social

Zazume continued working with Taboola to launch retargeting campaigns, reaching high-quality users who already engaged with the brand’s content, but hadn’t yet converted. Zazume used the Taboola Pixel to track user behaviors on its website and identify users who completed a certain action to retarget them with new campaigns.

Taboola led the retargeting process, using Taboola Trends data to optimize campaign creatives for clicks. For example, we found that images with people looking into the camera can increase clickthrough rates (CTRs) and engagement. Zazume also used Taboola SmartBid, an automated bidding technology, to optimize campaigns to drive conversions. Smart Bid uses campaign data to predict how likely a user is to convert, and then adjust the advertiser’s bid accordingly.

With these retargeting tools, Zazume achieved a 60% lower CPA than its goal. Taboola also drove the highest quality leads among all of Zazume’s acquisition channels, including search and social. As a result, Taboola is now responsible for 4% of all the brand’s leads, 20% of which are qualified, which is up to 6% higher than the average from search and social channels.

Going forward, Zazume will continue allocating their campaign budgets to sponsored content and working with Taboola to drive performance results.
