Here I am going to share a site with you where you can get unlimited SEO friendly dofollow backlinks in very less time. Site is www.omforums.com
For now we need to create quality backlinks from different source of network such like web 2.0, social site, elgg blog, video sites, press release sites, directory site etc. to rank site on google. Most of we suffer a lot after penguin/panda update because of low quality backlinks. Your mentioned site is looking good, but don't know how much quality links will deliver.
Any links you get from content, relevant sites is SEO friendly, so try to get backlinks from guest posting on relevant blog, it would help you a lot.
Great new forum site . Try to push your Page Rank in the short time and i believe it would help you to generate more users to build backlink on your site. Because most of webmaster not only want dofollow link while they prefer to get high backlink from those high PR site as well.
Define SEO friendly backlinks? With all the recent changes in Google, i am not sure about what is friendly and what not anymore.
Since Penguin, pretty much any links you "manufacture" by "planting" links on sites belonging to other webmasters is only going to lead to your site being filtered by Google. This includes signature links here and on other forums, spamming blogs, article submission, video submission, directory submission, and any other spam technique you come up with to build links quickly. If your domain is of value to you then the ONLY way to build links is to create great content and tools that other webmasters will WANT to link to themselves without you having to "plant" an unnatural link on their site. Build something great... find sites that would find what you built useful to their visitors... and let them know about your content/tools. Let THEM decide whether they would like to link to you. If your content and tools are low quality or even just mediocre, getting links will be a bitch. If you truly have built something great then you will have NO problem getting natural, editorial links from webmasters of other relevant, authoritative sites in your niche.
Create awesome content and share it. Wait till some users and bloggers link back to you. Best and natural way for getting SEO Friendly backlinks.
If you want to build quality links that will stand the test of time, I would higly recommend that you read everything you can find written by Eric Ward (ericward.com and also contributer on Search Engine Land's Link Week). They call him "Link Moses". He's probably the most famous and best link builder on the planet. When Sports Illustrated or National Geographic launch a new web site, they call Eric to promote it. He has been preaching merit-based link building forever... essentially, that good link building HAS to start with great content. You have to create something that other people would die to have or read. Once you've done this, building links for it (not planting links, but getting other webmasters to link naturally) is VERY easy. Read his old posts at ericward.com. They are pretty much timeless.
I don't know if you are trying to promote your own forum or not, but you can find this kind of service also on DP.
