Promotehour promised me to write a marketing article and have it published in 4 good reliable resources.
The article they have prepared was absolutely illiterate lame bunch of keywords. It was full of mistakes, tautology, and super primitive school level language. I'm not a native speaker and I hoped they had marketing gurus who would write something cool, but they outsourced it to someone who barely spoke English. I had to rewrite everything!
As far as publishing the article. They promised that the campaign (including writing the article) would take 6 weeks, but it took 6 months with no real results. At the beginning they promised that our article would be featured in TechCrunch, TheNextWeb, Daily Mail, Forbes, Entrepreneur, and Fortune (the list is from their email). In fact, all articles have been posted on some crappy websites specifically created for posting paid articles. Some are so bad that links are not even properly highlighted and you cannot find a link to your website. Interesting that all these websites include fake number of Facebook shares and views. When you see all that, you feel yourself a scammer too.
Eventually they stopped even responding to me. Extremely bad experience!
