A great article over at photocritic.org about SEO (search engine optimization) for photographers. While I was doing most of this already, there were some good tips that I had missed.
It's worth a read, and if you haven't already subscribed to their RSS feed I highly reccommend it.
As you can see, a quick search on Google for "Bob Shull" yields me a spot in the number one position. However, a search for "Northwest Arkansas Photographer" puts me on page 3 of the results. I've obviously got some work to do still.
