A video strategy which makes the right people, with the right intent see the right video

In order to achieve that, we started off with data research. This audience research gave input on which products within the electronic domains were searched for the most, what type of content the audience loved to watch, and how they behaved within the Google ecosystem. We combined this insight with an in-depth analysis of the existing review market on YouTube. Data showed huge potential and with this research, we knew exactly which video topics we had to create.

The perfect mix between entertainment and help content:
Sterren Reviews

In general, review formats are labelled as factual and informative – with less room for creativity. Our in-house creatives wanted to challenge this. The first thing people do when looking at an e-commerce platform is scan the reviews given by real people. This is exactly what the power of is. Being the biggest archive of real-life user experiences, we chose to create a category-like review format based on real opinions: Sterren Reviews.

Being the biggest archive of real-life user experiences, we gave them a voice with a branded entertainment format.

Taking the review game to a whole new level, the series uses the iconic user reviews and combines this with a good amount of humour and not-so-scientific product tests. We’ve added a relaxed atmosphere and relatable hosts who give the viewer a perfect overview of every product and category. The meme-like video edits magnified this. To make sure the content maximises performance, we pretested the videos and thumbnails among an unaware test audience using AI technology. This way, we could make creative tweaks before the content went live.

A media plan focussing on gaining as much quality attention as possible

By targeting entertaining and captivating content to a target audience with extremely high interest (thanks to our data research) the viewers kept on watching for a very long time! Custom audiences were created based on real-life intent-based data. Only the people who showed an interest in buying specific electronics were targeted. With a budget of 48K, we’ve distributed 12 Sterren Reviews with skippable in-stream ads. This resulted in huge amounts of view rates, viewing durations, and average percentages being watched.

The Results

We gained attention from the right people due to spot-on targeting and unique yet entertaining content. Resulting from clear data research.

Within Q4 of 2022, 12 episodes gathered over 1.9 million views, with even top rankings for some episodes. On average, viewers watched 5 minutes and 35 seconds each episode, accounting for an impressive 52% of the review’s entirety. Yes, you’ve read that correctly – this number includes viewers of the ads as well.
