With linkbuilding, it is all about diversity, not just volume. Today links need to seem natural and built out over time, across many domains, and many types of links. Among these types are profile and forum backlinks.
With profile backlinks, a new account needs to be created with a site where you have an account and create your own profile that represents who you are. Many of these profiles allow do-follow links (where the link counts towards your ranking position) and the anchor text used (the text within the link itself) is a major factor in how the link is categorized with the search engines.
For instance, a profile on a popular site with the name doglover and a link in the profile to your site using the link anchor text, Dog Grooming site, is likely to be indexed by the search engines in the Pets > Dog > Dog grooming section for searches.
Message boards, also knows as message forums, can also be a useful type of site to place a link. With some message boards, you can place a link in your profile, and this may be do-follow or no-follow. It depends on how the forum is set up.
Additionally, often you can add your own personal signature with some text and a link, sometimes several links, which will then display that the bottom of each post that you make on the message board itself. Whether you are allowed to add a signature will often depend on the forums policies.
Some restrictions that can prevent this feature include message post signatures being only for subscribers or a minimum number of posts must be made beforehand or the account must be so many days old first. These restrictions are there to try to prevent forums being used for mass backlinking programs.
Profile and Forum Backlinks
Profile and forum backlinks should be part of the overall package of backlinks to create a varied backlinking profile. All links are traceable and it is a good idea to mix up things. Spreading the links out over time, rather than posting thousands all in a matter of days with the same anchor text, is the best way to help to boost your search engine ranking.
