It's difficult to get links from popular websites unless you've got some great information which would be of interest to the people who visit those sites. The only problem is sites like huffingtonpost will curate your content and get all the credit. So there's no way you're going to convince the owner of a popular website to link back to you [unless they have something ($$$$) to gain]. It's easier therefore to dedicate your time to churning out ONLY informative articles that visitors to your site will find useful. If you're very good, be sure that people will start talking about you and the big boys [webmasters of the popular websites] will want to know more about you. They'll quote your articles and link back to you so that when you mention them in any of your posts in future they can get $ome traffic from you.
On the net traffic=$$$$. So if you desire to exchange links with popular websites that get a lot of traffic then you need to prove that you can send traffic their way.
