I’ve said it many times before: the single best thing 5-minute thing you can do to help boost your blog’s search-engine mojo is to add links to your blogroll. Lots of them.

The more sites you link to, the more will link back to you, and the higher your ranking will get. Trust me, it works. And it doesn’t take more than a couple minutes.

If, however, you’ve reached the point where you’ve added so many links to your blogroll that it’s staring to get unwieldy — 20, 40, 80! — it may be time for you to divvy up those links into smaller widgets. Usually bloggers do this by assinging the links different categories. For example, on the LoHud Yankees blog, Pete Abraham separates out “Other Beat Writers,” “Yes Network Blogs,” “Fan Blogs,” “Cool Sites,” and so on. Another blogger I knew in Westchester had a religion blog and subdivided his blogroll by religious demonination.

On Kevin Callahan’s Into the Outside blog, he devides up his link list like so:

That’s just a small snapshot, by the way. The full list is about 5x that long.

In order to enable grouped links, you’ll need to activate a plugin that enables this function and adds the widget to the sidebar. That may sound intimidating, but it’s actually quite easy. Below is a video — creating with my snazzy new screencasting software, ScreenFlow — to show you how to do it.
