Building backlinks to your website?

[Jake]

Give it time, those backlink reporting services follow links from site to site to discover new backlinks, it takes considerable time to go through billions of links.

Be aware that blog comments are some of the lowest value backlinks, getting them from relevant posts would help a bit, s rule of thumb, the easier a link is to get the less valuable it is, try to use a name that sounds like a persons name to avoid getting your comment removed, those that don't care about spam keywords for comment names are probably worthless pages.

Mix up your backlink sources to avoid being flagged as unnatural link patterns, that means some noFollow even though the value is limited, forum post and social bookmarking links, and if at all possible better quality links like guest posts with in body links or at least article directory submissions.
