Just in case you've forgotten, an outbound link is a url that you have on your site that points to another website.In today's Google PR obsessed Internet world, everyone is completely focusing on getting in bound links to your site. While you should always be on a mission to get more sites to link to yours, you must not forget their polar opposites.
Remember, by having outbound links from your site, you are in essence "voting" for
site you link to. This is part of
entire ranking algorithm process for all
search engines. The idea is, that if two sites are similar in content and design, a site with more links pointing to it would be considered more important by
search engine.
So then, why should you help out any other site? Actually, by carefully linking to other relevant sites, you are increasing
relevancy of your own site.
Pretend I have a pizza shop, and I am located in Anywhere, USA. It's a typical site that displays types of pizza, store location, hours, and coupons. I also know
power of outbound linking. For this case, I am going to link to 10 sites: Domino's, Pizza Hut, Little Ceaser’s & Papa Johns. Next, I link to 6 sites that are physically located in Anywhere, USA. (And their physical addresses are listed on their sites.)
Now, I will switch roles and view
site as a search engine spider. I navigate through
site, and determine that this site is about pizza. Then I find a resource page and discover some well-known links (Domino's, Pizza Hut, Little Ceaser’s & Papa Johns - and as
spider I know that these are major players in
realm of pizza). Next, I find 6 links to sites located in Anywhere, USA.
So, as a happy spider leaving
site, I now know that
site I just visited is about pizza (site content and links to
major players of
pizza industry), and that it is located in Anywhere, USA.
