This brief slideshow introduces some of the factors that go into Google, Yahoo, Bing and most of the search engines to index your online content. A few of these slides are meant for a technical audience, and a couple are directed at content editors. It's only 10 slides long, but most of you would find this interesting.
Something to note: from a technical perspective, most of the wizardry is done for you automatically.
The point to take home is: Write interesting content!
