It's too early to say either way whether the practice is possible. In reality though, this should only be a fear of new website owners. I'd imagine that if you have had a regular link build routine over the last 12+ months, you are going to be much less susceptible to a reverse SEO campaign than you would be if you were just starting out. With Google really cracking down on low quality links and non-varied anchor text though, it's certainly something they are going to have to closely monitor. WebDev
I would describe negative SEO as self defeating, a bit like MAD, if everyone engages in it everyone loses. My personal opinion is if everyone is simply focusing their time and effort on trying to destroy each other, it means no one is focused on making the web better for users.
You just need to keep on building good quality theme based links, negative SEO will not cause a bad effect on your rankings.
Well in Negative SEO,there are some shortcut method through which you will get rank fast so but its not preferable just go with quality link building and make unique and fresh content everytime to create quality backlink.
Negative SEO is the reverse of search engine optimisation. The aim of search engine optimisation is to increase a site's visibility in the SERPs. With Negative SEO, the aim of the procedure is to reduce a page's rankings in the search results.
Well, as you've seen from Panda (and Penguin): a problem with one part of the site can cause an overall ranking problem. What you have to remember with negative SEO is that it's hard to do with links (the links just won't be counted), if not impossible. Where you could be really hurt is if someone has access to your site such as editing content or even modifying scripts or HTML itself. There has been duplicate content out there for years and Wikipedia gets copied all of the time, including on some spammy sites, so I can't see how it will happen. Just make sure your site is secure, always keep it up to date if you're using a CMS and install security plugins if it's a CMS (most of them have some good ones). If your site allows UGC (User Generated Content) then try to moderate it in some way (human and automated). That includes even if it's blog comments, for example. Good luck!
Do not do heavy interlinking websites to move in page rank and do not use always software do it also manually in building some links. For more information just add me to my skype. seocentralservices
