Thank you in advance.
One suggestion, if you haven't already done it, you need to protect it from links/sites like wikipedia. They have million links and your automation will enter in endless loop. This is is an opportunity for someone to break your service.
I have ordered cold package. I received the links on time, the stats are the same as what was advertised, even one of the link has bigger metrics.
Can't say nothing for now about the articles. I'm waiting for results and will buy more.
