Hello, i am running an Android application. I am using rss feeds and i am sending everday new articles to my users with using rapidfees (rss provider). So i have no websites. I am using rss url which rapidfees gave to me. It has been 10 days since i published the app and i have 500 users and 22.000 impressions for my articles. So i want to replace some ads on articles. But nearly all the ad services want a website url and want approve a website. I just have feed url. What should i do, which service i could use, is there any advice for me? Thank you very much.
