Understanding Links, for Search Engine Optimization
Actually, no. That's because links are basically uni-directional entities – they take you in one direction (forward), but they don't take you back. Yes, I know what you're thinking – you can go "back" using the back arrow in your web browser, right? Yes, but that's different ... it's important to understand that the link itself is not what's taking you back – it's the web browser software, which has been designed to remember the last page you visited so that you can go back.
It's best to think of links as being either inbound or outbound (from your perspective). So if you link to me (an outbound link, from your perspective), then you help my search engine rankings because by linking to me, you're signalling to the search engines that you think I am a valuable source of info – so my ranking goes up. The only way I can really help you in return is to create a separate link from me to you (an inbound link, from your perspective). This signals to the search engines that I think you are a valuable source of info. (And linking to each other like this is called "reciprocal" links.) It's important to note: having outbound links doesn't hurt your site rankings, it just doesn't help. (Or if it does help, it only helps a little.)
As I've discussed before, having inbound links to your site (that is, links from other sites to yours) is by far the most powerful way to get great search engine rankings. If you get 5 other sites to point (i.e., link) to your site, that tells the search engines that a few people think you're an important source of info, and your rankings will be helped a bit. But if you get 100 sites to point to yours, or 1000, that tells the search engines that A LOT of people think your site is a valuable source of info, so your rankings will benefit much more.
*However* before you run off to start asking other site owners to create inbound links to your site, please read my previous blog post about how to raise Google search rankings ... there are right ways and wrong ways to get inbound links, and if you manage to get a bunch of the wrong type of inbound links, Google just might blackball your site, which is something that nobody wants to happen.
