Yes, it is possible to run direct link campaigns for betting offers without using landing pages, but it depends on the traffic source and the offer rules. Some traffic networks allow direct linking, especially for push ads, but others may not. Also, some betting advertisers want users to go through a landing page first to warm them up before hitting the offer page. Using a landing page can help explain the offer better and increase conversions, especially if the offer page is heavy or redirects slowly. On the other hand, direct linking is faster and can work well if the offer page is clear and fast-loading. It is a good idea to test both and see which one performs better. Check with your traffic source and affiliate manager to be sure about what is allowed. Have you looked into the performance difference between direct linking and using a landing page in your tests?
