Unindexed website

My website stopped being indexed on google after using this product… after a few months of using this plugin I noticed a massive drop in organic traffic and spent days trying to find the issue. After resorting to posting about my issues on the google help centre some nice people managed to identify that google wasn’t able to reach my website and something was blocking it… it turns out it was this plugin. This has not only cost me a lot in time trying to identify the issue but it has lost me revenue as all the keywords and even my brand name was unindexed from google
