If your goal is to drive more traffic to your web site, you can submit your site to each search engine one at a time or you can submit them to all key engines at once and then monitor your site's ranking. I use Web Position Gold. By using Web Position Gold, I learned which key words worked best, how to optimize meta tags and what pages on our site are the most popular.

Photos are a good place to start.
Next time you buy a camera, consider a digital model. They are easy to use and make it easy to incorporate pictures into your website. If you don't have a digital camera, have your filmed processed onto compact disk. There are a number of websites that offer great graphics. BabeonHD's Free Hawg Graphics is outstanding.
