Link Building is still very important off-page SEO tools even in 2015. You should give attention on high PR & high quality dofollow backlink. Buying backlink may not be good quality even it is from fiverr.com. It should be avoided. It is better if link is builded by naturally which Google prefers most. My opinion is : Create high quality dofollow backlink by yourself. If you can do that, you may be able to sleep sound at night. Trust me, if you can spend few weeks digging through your high quality backlink, your site will be ranked soon to Google.
How to Check a Link Dofollow or Nodofollow:
Follow Links or DoFollow:
Backlinks that count as points by giving SEO link juice and boosting the page rank of your linked-to sites and by helping them to go higher in SERPs result.
A link that does not have point count in the page’s favor and does not give link juice or boost any PageRank, and doesn’t help in the SERPs.
From the above statements, you might be misunderstood. You are thinking that you do not need nofollow link anymore. It is not true at all. Ofcourse, you should have sufficient high quality nofollow link especially on high traffic sites. High PR sites can give you a lot of referral traffic. Say an Example, your reddit URL on your profile is no longer a follow link. However, do you ever think how many people click on your reddit URL and visit your website?. So, if reddit URL (nofollow backlink from reddit) is nofollow now, but, it is high quality nofollow link which cannot give link juice but can give high volume of traffic. So, you should not miss it.
