First things first, These tricks are not based on the usual "Powered by elgg" footprint. Usually, with this method you can find backlink sources that you won't find with the basic footprints of an open source platform. Think out of the box and you will be able to find some other great places. You know, when you say payday loans, ugg boots or phen pills you think about some of the most spammed to death industries. Niches like this type are targeted by the most heavy spammers ever, if there is a place that let's you add a link for your website - be sure that payday loans or ugg boots guys know about it. Either use your crawler, Scrapebox or put your assistant to do manual searches - is no doubt you will find something good out of this. For today's example I have choosed EDU blogs because these are the most searched but this method can be applied on anything. I don't want to spoonfeed not because I don't like it (easy with PMs bros - thanks) but it's not the case here. You will figure it out by yourself and hopefully some other twists will come to your mind. Here you have it: .EDU: Code: intitle:"buy phen" site:edu inurl:post "beats by dr" site:edu intitle:"buy" "Unauthenticated User" site:edu "payday loans" "Unauthenticated User" site:edu intitle:"ugg boots online" site:edu intitle:"buy cheap ugg boots" site:edu "louis vuitton bags" site:edu intitle:"payday loans" inurl:node site:edu intitle:"cheapest" "buy" site:edu intitle:"shoes" "buy" site:edu "sex toys" inurl:"profile" site:edu Twist: Go to Google click on Search tools and put that to Past 24 hours or Last week. You don't have to be exact on these, a simple "ugg boots" site:edu search in last week should reveal some nice things. Here is the real gem, the best things you find by this. Find top promoted niches, use longtail keywords of that niches (Here I mean don't use general keywords like ugg boots because you may end on some college girl on ugg boots - but as a longtail no one will write legit about "ugg boots online" I hope you get me) And some other simple trick that is a little offtopic (just a little), for those who have ahrefs/majesticseo/opensiteexplorer analyse sites you know are used to create backlinks examples: wordpress, weebly, angelfire... By analyse I mean using tools like ahrefs (haven't used others) you have access to sort and find top and most important pages/subdomains of a domain. Now that you know the best possible web 2.0 blogs you follow the path of tier 2 and you know what you need to do to empower your own blogs. Hope it triggers you some ideas.
