Search engine optimization.
What is it? Getting your site to come up high on search engines. It's also something that the company I work for spend God only knows how much money to hire people to do for them.
And I just did it for my little ole web-log with a Google search and ten minutes. Some days, I'm really quite proud of me.
(Other days, I have to have the volume slider on my computer explained to me over the phone, but then nobody knows about that.)
