I want to sell my Tumblr adult blogs, but don't know how much are they worth (one blog is for one pornstar). Selling four blogs together, they have 35.000 followers on Tumblr. Two are really bigger than two others. All blogs are growing daily (new followers - few daily without posting new content). I usually post one or two pictures per two weeks on every blog (then receive more new followers etc..). Blogs are growing without any cost (no hosting or domain cost) & few minutes per month. I posted always only pictures, but if you will post daily or weekly example GIF (animated pictures) or videos you can get better user interaction (more followers, visitors...). What do you mean? How much are these Tumblr adult blogs worth together?
