I am not a guru of seo to tech you something .I am just sharing a method which i implemented to get Authority backlinks which google see as real backlinks. I tested this method for travel niche but it can also work in any niche. Here we go :- At first we will have to create a list of wordpress and blogspot blog related to our niche. The blog should not be popular , yes NOT popular but old ones. We will have to find blogs owned by housewives , aged peoples such people know very less about seo and internet marketing they do blogging just for fun.Now we will have to talk to them explaining them about importance of seo and how they can earn money from there site ( also tell them about blackhatworld.com because they really need it) . After that ask them for guest post and in turn we will give them some high pr backlinks using GSA or purchase from Fiverr (I purchased 2 gig covering all 52 blogs which agreed to do guest post.) All backlinks were given to my posts. How to find blogs :- Regional blog directories like indiblgger.in How to convince bloggers :- Have general chat to them about your blogs .Use addmefast.com to increase their facebook likes .Say them you like there blog and give them backlinks before asking about gust post. Trust me you can easily convince them. Results of this method :- I got 52 high authority backlinks form aged blogs spending only 5 hours and 10$ which ranked my medium competition keyword to first page in 2 week.
