PageRank sculpting came out of the idea that virtually any page will have links that are important for users but not necessarily that meaningful to receive any PageRank that a page can flow. Navigational links are a primary example of this. Go to a place like the LA Times, and you’ve got tons of navigational links on every page. Nofollow those, and you (supposedly in the past) ensure that the remaining links (say your major stories) get more of a boost.
Search engines are smart, but they still need help. The major engines are always working to improve their technology to crawl the web more deeply and return better results to users. However, there is a limit to how search engines can operate. Whereas the right SEO can net you thousands of visitors and increased attention, the wrong moves can hide or bury your site deep in the search results where visibility is minimal.
The best strategy to get backlinks is to create great content and let other people promote your content. However, to get started, you can create your own links to content on your social media platform, ask your friends to share your content on their websites and social media, and if you can find questions in forums that your content answers, you can always post it there.
Bob Dole (interesting name), you’re certainly welcome to use Bing if you prefer, but before you switch, you might check whether they do similar things. I know that Nate Buggia has strongly recommended not to bother with PageRank sculpting in the past, for example, or at least that was my perception from his comments at the last couple SMX Advanced conferences.
While ordinary users were not that interested in pages' scores, SEOs of a different caliber felt that this was a great opportunity to make a difference for their customers. This obsession of SEOs with PageRank made everyone feel that this ranking signal is more or less the only important one. In spite of the fact that pages with a lower PR score can beat those with a higher score! What did we receive then, as a result?
