Hi Lisa, Good Question. Yes, SEO (Search Engine Optimization) will work with all of the major search engines. A well informed SEO expert will help you optimize each page of your site so that it is easy for each of the engines to "read, categorize and store your site information. You should not have to do this often. Having great content that relates to your web site is the single MOST important factor in getting high rankings on Google & Yahoo. As a certified SEO/SEM/PPC expert, let me suggest that you go to Amazon or Borders and pick up a $20 book on the subject. Get the latest/newest one you can find. Then read through it and you will be able to do most of the optimization yourself. It is not rocket science, but it will take some time and work.
