You should consider building a new web site separate from your main site that functions as an information hub for your industry. You can use RSS feeds to dynamically create much of the content for the site, which will save you the effort of trying to manually updating it with new links or articles. So why would you want to take the time to do such a thing?
There are a few good reasons, but the one we are most interested in is this: to have a means to guide search engine spiders to other web sites that rank to your main site, without linking directly to them from your main site.
The reason you would want to guide search engine spiders in this way is so that you do not end up with nothing but two-way links, but you also want to make sure that other web pages that contain links to your site are found. There is certainly a good chance that Google (or whoever) will find all those links on its own, but why not make it easy and point right to them?
To really take this strategy to the next level, you should give your new site, the information hub, its own IP address so that there is nothing tying the sites together. But even if you don’t do that, it is still a good strategy because it eliminates cross-linking between other sites and your site.
Another big advantage is that the information hub gives you another opportunity to get your marketing message across. But avoid the temptation to make it just an extension of your web site for purposes of selling your services. It needs to stand on its own as a valuable source of impartial information.
