Welcome to the Q&A Forum

Thanks for your replies! Gee, I thought things are easier @ Marie no I havent got a google warning nor were my search results downgraded by penguin update. After talking with a few SEO companies and receiving astronomical offers I have decided to keep trying myself. A am currently doing a lot of different activities and after on-page optimizing am trying to improve backlinking. I have reached great results over the last few week, but I am constantly thinking that I might make some dummy mistakes Since I have heard that google is downgrading or even punishing sites with backlinks it considers bad, I thought there might be an eays way to check it before problems occur. @Tom Thanks, I have found LinkDetox just before posting my question here and have just tried it out. Something sort of I have meant with my question. Unfortunately, for a buck it doesn't provide a full information. @Irving Thanks, an interesting tool. Checking every single domain linking to me should be quite time consuming. Strange that the engine would report "essex" positive - I hope that google itself is not that stupid.
