The file names were changed, all other elements were modified slightly.
OK, so here's my question:
If you take a page that ranks well for important keywords, and change nothing except for the file name, then link it into the site and simultaneously remove the original from your hosting account -- Does G see it as an entirely new page?
If so, wouldn't you lose the points you get for the "age of the page"? Don't we see the age of the site as one of the hundreds of criteria in the algo, so in this case, the page "age" would be loss? Or is that not a factor?
