Part 1 - Considering Your Audience
Part 2 - What's in a Domain Name?
Part 3 - Search Engine Optimization
Part 4 - Describing Art Online
Now that you've settled on your domain name and have some semblance of an idea for a design, there's yet another aspect of designing a website to consider - SEO (or Search Engine Optimization). SEO is an overarching term used to describe the elements of a webpage and strategies which can be altered in order to make it easier for search engines to find your page.
Now, one thing I will make clear at the beginning, if you don't want your site to be easily found by search engines, there is no need to go through the trouble. Sometimes, like in the case of personal portfolios to be presented to art directors, we don't necessarily need to obey these rules of optimization and don't want people stumbling upon these pages because they're not meant for public display, beyond job solicitation. By all means, go crazy with Flash and other things which aren't very search engine friendly. (See this article on hiding your webpage from indexing)
But chances are, you do want your webpage to be found easily! For this purpose, I personally employ Google's edicts of website optimization. As one of the foremost search engines on the net, Google also offers a wide variety of free tools and guides for webmasters to use in lieu of hiring SEO marketing experts.
A good first step once you have a completed page is to submit your url to google or the open source project to begin indexing your page with various search engines across the web.
Some Things to Remember:
Note that web standards are always evolving so this may change in the future! Also, if you try to hide your text using CSS or making your font small and the same color as your background image, Google may remove your site from its indexing if it is deemed 'deceptive in intent'!
For artists, this means being sure to link to your website from your forum signatures, online articles, blogs, and website profiles. The more linking, the higher your rank! But also remember to keep these links relevant and pertinent to your content! One wouldn't link back to their art gallery from a webpage on baseballs unless you're doing baseball art.

Additional Tools for SEO
For an example of its usefulness, Alerts helped me to discover that a Twitter-bot took my artist username so I could put out a notice saying that this user on Twitter was not me! Alerts also helps me to keep an eye out for art thieves who are are dumb enough to use the same title on images that I originally used (Tineye is also good for this purpose, as it is an image recognition tool that scours the net for you).
