What is Negative or Reverse SEO? How to detect if you have been a victim of Negative SEO and how I can recover it?
Hey there, Interesting Question and it will take time to answer. i have extracted a blog, go through that & you will get to know what to do http://www.eoantechnologies.com/blog/seo-questions-a-gigantic-list-answered-here/ Apart from that, try never Spam. Don't write a blog post it to multiple blog sites. Google will count it as spam & will penalize your site.
Observe your backlinks via GWT, Bing WT, MajesticSEO or Ahrefs. Can you see any strange patterns? Any non-relevant anchor texts? Any spam/nonsensical links? If you answered "yes" to all three questions, you might be a victim of Negative SEO. BUT I said "might", because what's often mistaken for Negative SEO is in reality just a full scale spam attack that exploits comments, guestbooks, forums and any imaginable CMS loophole. That form of spam attack was used long before Negative SEO ever existed. When you see that you've been spammed, you may contact the webmasters of the sites where the spam link has been placed and ask them politely to remove it, as possibly neither of you want spam crap around your websites.
Negative SEO is the process of downgrading a site/page’s search result rankings through implementing tactics that violate Google’s Webmaster Guidelines and to trigger negative ranking factors/signals, for it to be penalized or be affected by algorithmic updates. If you see lot's of backlinks which were done within 1 or 2 days on your site, you can recover it by “Disavow links feature” from Google Webmaster Tools, you can find out spammy and manipulative link building through Ahrefs.com, Google Alerts and Majestic SEO. You can also remove unauthorized links by Removeem.com very easily. If you think that some of the spammy links are already hurting your search rankings, you can report it to Google using the Remove Content from Google tool.
