I have managed to get some back links for my sites. These are from November 2009 onwards. But the problem is that many of these back links are not cached yet. I check this directly from Google. And when I see the "We're sorry..." error pages, I use some proxy servers like surfingincognito or stayincognito. Is there any way to get your back link pages cached quickly ? And if any back link is not cached, does it contribute to ranking or PR of the site ? Your suggestion is appreciated.
