Anymore, every time I launch a new site I detect perhaps a competitor trying to take me down.
My latest site...I was looking over webmaster tools and it seems to think that I have 6 missing pages. I do not. When I see what pages are missing they are pages I never created. I can also tell because I use Wordpress which hides the .php extension and all of these pages have the .php extension.
When I investigated who was linking to me, I found that someone had taken one of my articles without permission and published it on ArticlesFactory.com. In the author section they linked to my homepage, but also linked to a page that doesn't exist with their own keyword of choice.
It's obvious. They didn't use the article to link to their own website, they wanted to punish mine somehow.
It's so sickening - people can be pathetic. But I wonder what your thoughts are? I've seen this over and over again with many of my sites. Have you had this problem? do you think it affects your SERP positioning?
