Contextly does not provide "sponsored" content in our recommendations a la Outbrain or Taboola.
We believe that publishers thrive by building their audiences, and too often Outbrain and Taboola include low-quality clickbait that is intentionally not labeled well in order to deceive readers.
We believe deceiving readers is a very poor long-term strategy for publishers.
We are not, however, opposed to "native advertising" or "sponsored content"
We do help our publishers that run native content on their own site promote that content and get more readers to that content. We require that those pieces be clearly labeled as sponsored content.
If you are a publisher looking to increase the exposure of the native ads on their site, please write us at firstname.lastname@example.org.
