Interesting. Reverse engineering the Google algorithms is something with potential. >> If so, can you provide a link? > > Like with a lot of SEO findings in general, it's based on my own site :- > D.

Momentum, however, is a crucial bit and also coping with change, e.g. CSS, dynamic content, RSS feeds, Web applications... > At least in my case more pages = more traffic, holds: > > avg/day month > 81 sept 2003 > 700 sept 2004 > 3818 sept 2005 If only these recent referral spammers were genuine visitors...

And again I stress the importance of momentum. With RSS feeds and technologies, which I am sure many learn about in your pages, you need to snatch those subscribers during that short period of hype. Likewise, you need to get the links before your pages become out-of-date, old-fashioned or at worse scenarios -- mirrored or plagiarised in principle. Roy -- Roy S.
