You have to remember, if you only targeted dofollow backlinks only, google will pay attention to your site. And soon, they will put them to sandbox. The save way to build backlink is combine the nofollow and dofollow. You have also use different keyword as the anchor text too.
nofollow is an HTML attribute value used to instruct some search engines that a hyperlink should not influence the link target’s ranking in the search engine’s index. It is intended to reduce the effectiveness of certain types of search engine spam, thereby improving the quality of search engine results and preventing spamdexing from occurring in the first place.
Nofollow:
