One of my cites was hit by negative seo by unknown person. They are creating anchor text back links to my site from spam sites including those of porn sites and sites which sell Viagra and sex toys!!! Those anchor texts are my primary keywords. The anchor text links are positioned in the design of that sites, ie near the contact us, about us stuffs. What legal action i can take against them? Is there any way to delete those links other than disavow ?
If you do not know who it is, you have no chance of taking legal action. I think it is common when someone hires SEO people that they try to attack their competitors so that their site ranks better. Sadly, I only know of disavow.
You could try a civil suit, if you know who they are and they are in your country, but that could turn out to be a bigger headache (and higher cost) than it is worth. You could disavow, but the fact is Google might already be silently ignoring them (it all depends upon your own history of link building). Is your rank impacted? Then you should disavow. If not, keep doing what you are doing (in terms of marketing), which (hopefully) is very different (i.e. not spamming or other unnatural link schemes) from what is happening right now. Negative SEO (mostly - the main exception is if someone has actual access to your site and can do a lot of sneaky black hat things with it) is over-hyped and an easy scapegoat for people who end up getting caught out by Google. Otherwise, the only thing you can do (and it might not work) is send off emails to their registrar and web host. If either of them are active in Web Hosting Talk, then bring it up there, too. On a site like that it is quite likely to get a reaction, as it is where a lot of hosts get business and they need to protect their reputation.
Thanks ryan.... Well we have already approached the civil suite. But as everybody know, it won't help anyway !!! Let me try out with the Web Hosting Talk... Thanks again
Not much recourse, maybe try writing to the hosting companies hosting such sites and explain the situation to them.
Oh, and make a spam report to Google. It can work. I have had personal experience of this - I remember finding some dodgy looking links in Google Webmaster Tools for one of my site's. It was a group of .pl sites that seemed to scrape links and try to present themselves as a "directory", but that was to Googlebot. When visiting the links, I was presented with affiliate spam but when I set my user agent to Googlebot and refreshed, I saw the scraped links. So I made a spam report, checked back some time later and found the sites had been de-indexed.
