I came across ExactFactor today. It is a quick way to check your search rankings across the major search engines (Google, Yahoo, Live.com). The best feature are regular email alerts you can setup to receive whenever there is a change in your search engine ranking. As we do more and more SEO for our clients, this could be a good way to keep them in the loop. I say could be because SEO is a mix of science and dark magic, and can be a difficult are to build client expectations around. Either way, ExactFactor is a great tool for internal use. Check it out and let me know what you think.
