I first wanted to say thank you for providing that description. It is very informative.
I am seeing some of the things that you mentioned. After adding pages to a site, the keywords that the other pages are ranking for have not really moved.
It has been about a week since I added the new pages. Maybe I have to wait more to see what the effects are going to be on the older pages and the keywords that they rank for?
For keywords that I want the new pages to rank for, I am not seeing that particular page or the homepage rank for them. Maybe I have to wait more? But the new pages do have a cache version.
I think I should also mention that the cache version of the homepage is showing a date before the new pages were added. Do you think the date of the cache version of the homepage should be after the new pages were added in order to have a better idea of ranking changes for the older pages and/or the new ones?
