How to open a new page

Hi,

If proof is needed that Google spiders dynamic sites - I have plenty of evidence. In fact - many thousands of them, all kept in Google's cache.

Those pages also demonstrate why Google (and other Search Engines) are very reluctant to spider dynamic content. The number of duplicate pages is enormous. That harms everyone - Google, the users and the site too. An awful amount of resources is just wasted.

Having seen the consequences, the site's structure is now totally transformed. While still dynamic internally - it looks and behaves as static externally. So my question is:

What is the shortest and simplest way to 'persuade' Googlbot to 'forget' all the duplicate pages and start afresh? Is it JUST a question of time, or can one DO something about it?

Any ideas or suggestions?

Thanks!

mrdch,

The fastest way... Good question.

I'd recommend that you return a 410-Gone or 404-Not Found status when those URLs are requested.

Thanks for the idea!

Problem is - I still want the old style URLs to work :(
The site was up for too long to simply invalidate all the previous URLs.

probably 301 permanent redirects via mod_rewrite. If you would be happy redirecting all the old urls to your home page, it would be very easy.

On the other hand, if want to redirect each page to it's new url, it could be a tedious task.

Hmmm... I guess it would be.

Suppose that the OLD URLs are of the format of
...AAA.com/old/*
and the new ones are
...AAA.com/new/*

If I would block the spiders from the first directory - would that be good enough? Is there a faster way to get rid of the old cache?

Suppose that the OLD URLs are of the format of
...AAA.com/old/*
and the new ones are
...AAA.com/new/*

If you have easily-distinguishable URLs like that, then it's not so bad.

On Apache:


RedirectPermanent /old/ http://AAA.com/new/

Will redirect all requests for a page in /old to the same page in /new, and cause search engines to update their listing.
