On your question, today building up links might have the opposite effect if done wrong. Google has grown exceptionally smart to take into account the ages of sites that link to you, their own ranking and quality of content, to consider a certain link going to your site to be of more or less value. There are hundreds and hundreds of variables they look at. Prepare yourself as ranking well will come out of LONG-TERM effort and not a short-term enterprise. If you are a company, getting traditional publicity in media outlets, that would link back to you would do more good than having 500 link backs on low-quality young websites.
