Hello, I am currently trying to modify my keywords and content to increase my rankings.. (aren't we all ). What I am curious to know is this.. After changing keywords, density, etc - how long must I wait until the changes take affect. Let's put it this way, maybe... How can I know for certain if the SEs take the new page into consideration? I am spidered regularly (daily) by Google, Yahoo, MSN, and others. Thanks!
