I promote several affiliate marketing websites with Google and Bing and this year I wanted to give a try to Yahoo Gemini.
The platform is a mess, no editor, it's very hard to use it. After some time I had 5 websites on their platform and my monthly spending was approx $10k/month.
Last month I started a new campaign for a new website - in a couple of hours all my campaigns (new and old) were on Paused mode and I was not able to edit anything. I got an email response after more than 10 days (they have no chat or phone support and I did not get an account manager) stating that my account was suspended as my ads were for low quality websites. No one was able to tell my which website is low quality and why they suspend an entire account if only one website is low quality.
In this time my websites were promoted intensively on Bing Ads which places it's ads also on Yahoo Search and other properties.
