Some blog software applications have the ability to manage links within their system.  Companies utilize those links to promote the latest articles or news items about their company.  Links are important, though, and should not be constrained to your business blogging application.

If you're blogging for SEO, it's a great idea to share your links external from your blog.  My favorite bookmarking system is Del.icio.us:
Blogging for SEO Links and Bookmarking with Delicious
The nice thing about bookmarking systems like Delicious is that Search Engines utilize them to determine relevance... if a lot of individuals bookmark a link, it's relevant to the description and keywords that it's organized under.

If you're a huge fan of Firefox, there's an incredible Delicious add-on that allows you to save, edit, and manage your delicious bookmarks right in the browser so you never actually have to visit Delicious.

Utilizing an RSS Sidebar widget in Compendium, we can publish your bookmark  feed directly to your Compendium Blog.  This approach is a vast improvement than managing your links strictly within the application because search engines see the links promoted twice now, once in Delicious and once in your sidebar.

That's better blogging - from Compendium.
