I suggest you maximize the page on your screen to make each of the frames as large as possible. Many of the search engines require that you provide an email address. It allows up to 100 clipboards which can also be saved through restarts, plus many other useful features. Before you submit an URL, it's a good idea to 'renew' the page. Make a change in your HTML file, so that the search engines will see it as a new page.
Many search engines ignore repeat submissions of identical pages with the same creation date.
Some may even penalize you for spamming the engine. The changes you make need not be significant. Just change a word or two somewhere. Your email address will never be shared. Michael Campbell shows you how to get to the top of search engines and hold your position once you're there.
