It takes so long for the search engines that matter to re-index and recognise any changes in your sites. MSN is about the quickest and Google... well, if you're prepared to wait, you're looking at several months before your ranking gets changed or you see any major changes in how it views your site.
I've got inbound links from recognised and higher
PR sites. I have Google sitemaps. My sites are accessbile, relevant and follow useability guidelines...
Is this lag a ploy to make you spend more on PPC?
If, like me, you have relevant sites but not a lot of traffic, is there a way to speed this process up?
Strangely I have a site that doesn't really have anything happening with it but already has a
PR of 5 (not that it means anything, but it feels good).
