Over the past year, we have completely overhauled our approach to identifying user interests. By leveraging deep neural networks and advanced language models, including SeLLMa from Seznam, as well as the latest natural language processing techniques, we have achieved significantly more accurate content classification. Let’s summarise what this means for you.
What impact will the new interest targeting have on your campaigns?
- Higher click-through rate (CTR)
Using the new targeting, we are already seeing an average CTR increase of 14%, with all other conditions (ad format and placement) remaining unchanged. This means that you are reaching a more accurate and relevant audience.
- Improved user allocation
Our new methods consider the context of the entire text, rather than just the basic form of words. This enables users to be classified more accurately into the right interest segments.
- Continuous optimization
The “LLM as a judge” method is used to identify and remove classification errors, leading to continuous improvement of our models.
How does it work?
Previously, we used techniques to convert text from visited websites into a basic form, known as lemmatisation, so that it could be easily analysed. Based on the occurrence of typical keywords, we then categorised the texts according to relevant interests. However, this method was unable to capture the overall context of the content fully.
We now generate hundreds of sample articles for each interest category, using advanced methods to compare the content with predefined patterns (a process known as vectorisation). This approach enables us to assign users to interest categories with significantly greater accuracy. Additionally, we have begun training our language model according to the IAB taxonomy, enabling us to transition seamlessly to a pan-European standard for identifying interests in the future.
What impact will this have on your campaigns?
- More relevant traffic
Thanks to more precise targeting, you can reach an audience that is genuinely interested in you and has a higher conversion potential.
- Possible reduction in the size of some segments
Interest-based targeting may result in smaller segments, which could affect the total number of visitors.
In light of this new feature, we recommend regularly checking the results of campaigns targeting user interests. To reach a wider audience, consider increasing your cost-per-click (CPC) bid or adding related targeting.
You can start using the new targeting options immediately
We believe that the new interest targeting feature will help you to achieve even better results and reach a more relevant audience. If you would like more information or support, please contact your Sklik consultant or use our contact form. We are always happy to advise you on how to make the most of more precise targeting.
Over the next few weeks, we also plan to introduce new targeting options for RTB, enabling you to use it for programmatic advertising. We will inform you of the exact launch date.
