A client that I am working for has come to me with a problem. Their Google Adwords account has been disabled because there is a bunch of traffic to crazy non-existent pages on their website. Here are some examples:
http://example.com/ffdd1g/military-decoration.html http://example.com/ffdd1g/my-first-love-story.html http://example.com/ffdd1g/72-x-42-shower-pan.html http://example.com/ffdd1g/dz-diagzone-pro-apk.html http://example.com/ffdd1g/daraz-seller-account.html http://example.com/ffdd1g/uo-outlands-macros.html
All of this content doesn't exist. I've checked their sitemaps.xml and robots.txt to see if there was any of this content in either of those files but there wasn't. I've looked in their apache2 logs and noticed that basically the only traffic to these pages are bots. GoogleBot, BingBot, AhrefsBot and SemrushBot. Looks like Ahrefs and Semrush (two SEO companies) are big contributors to this traffic.
I'm afraid that someone before me may have used some sketchy backlink generator and caused these links to be populated all over random websites with no hopes of getting the links removed and the crawling stopped.
How do I get Google to stop indexing this traffic so that I can get my client's Google Adwords campaigns back up and running? Any ideas would be enormously helpful.
