  Joe Pyle: I have designed a WP site, followed the rules, and gotten to the top (1st page, generally) of the search that I'm wanting. A competitor is using poor form, and has for years, to get his site to rank higher. Is there a way to report his unsavory practices (such as hiding text in <div> tags that is just jumbled keywords made into sentences) to Google? It's so frustrating when I've tried to follow the rules laid out and he circumvents them. Thanks

  Jim Munro: Add this to Chrome, Joe. It's an extension to make a spam report while you are logged in. If you see egregious spam, report it and move on. You won't see immediate results but at least you have done as much as you can.

  Jeremy Estes: I would just stay focused on my own stuff.. Otherwise if it is straight up spam, I guess you could tweet @mattcutts

   ;If you think that's bad, just be glad you don't suddenly have 20 competitors backed with millions in VC cash who buy big press write ups every other month and bump you out with the resulting increase in their domain authority alone.

  Dmitry Grunt: Better work on your own content than sending spam reports.
  Google knows all tricks and sure knows about hidden text.

  Hannah Eisenberg: You cannot control others, just focus on creating amazing useful content for your clients on a blog - being the best you can be is truly the only thing that will pay off in the long-term.

  Neil Hannam: I'd just focus on yourself and your site. Google will catch up with your competitor sooner or later and even if they don't you can out rank them by doing things the right way but better than them. Whatever you do don't be tempted to stray into the dark arts just because they seem to be getting away with it for now. Good luck

  CeS Inspections LLC: I've been waiting on Google to catch my top competitor. He ranks first in Google maps but his business is a post box address. His business isn't in Houston so he's gaming the system

  Jim Munro: Good luck with that plan. I'm not saying I have any special knowledge but I think that the entire process of manual actions hinges on engineers actioning spam reports.

  eBizWebpages: I have to agree with Jim. The squeaky wheel gets the grease. If they didn't want your feedback then there wouldn't be a way to send it. Just make sure your own ducks are in a row first and don't abuse the reporting system.
