I have just reviewed my article submission report from backlinksgenie. I ve noticed some domains in the report are not indexed in google. Does that mean these sites might be penalized by Google? I have messaged the online representative Chris about this matter that I ve found. He replied that the network is healthy and there is absolutely no issue with it. However, he did not explain much about the reason why those domains were not indexed. Can someone share some thoughts with me on this and is it safe to continue using their service?
