getting link backs, and getting your site noticed.
There are sites out there, and you have more than likely heard of them who are “an authority” in the field that you yourself want to build a site about, whether it is about computers, cars, or baby carriers.
If you look at sites that are an authority in the field that you want your site to be about, you can build your site around that chosen concept, whatever it may be, and request a link from the authority site, to place on your site. Keywords to search for are things like “linkbid directory“.
That is just a basic starter spot to start from, looking to sites that have more information on authority sites, and link back directories will get you much more information, and you can also look at sites like www.thetopweblist.com.
