For those of you that haven't ever considered the fact that a search engine only spends a few miliseconds on your site each time it visits, you should be happy to know that there are ways to eliminate or at least reduce the risk of the search engines not completing there scan of your web pages. And at the same time, you can increase the total amount of pages that get looked at during each visit from the search engines.
How do you do this? It's simple, reduce the amout of code on a page and eliminate excess white space or blank space of your web pages. You should also put as much code as possible inside of css files and if there are sections that aren't important for seo, you may want to put these sections into an external javascript file.
Another good idea is to purchase a compression program that will do all of this for you. If the program is robust enough, it can even map the pages and reduce even more file size. You may want to look up a program like w3compiler or something similar if you have a need to compress files to the max.
