Are there too many requests from the Google indexing bot, or referals from actual readers clicking through from google?

If it's the first, then you could use robots.txt to only allow google to index your front page.

My blog is not realy a blog but a daily updated databese with all sorts of information.
Movie reviews, songtexts, recepies for food, poems...
So indeed all those seperate articles are in google - and I do want them to stay there offcourse.
In my stats I see a lot - a lot - articles that are found trough google..
But not all 28000. It's about 1 or 2 per minute maximum.

So updating only my frontpage is not at all a solution that I want.

Might be because google follows all you links, all your categories, calendars etc, - this way, every content is indexed several times - a common problem. Look at som Search Engine Optimisation posts here in the forum. I've put this code in the header of the _main.php in my template:

<meta name="robots" content="<?php if( ( $disp!='posts' && $disp!='single' ) || ( $disp=='posts' && ( $paged>1 || $cat!='' || $m!=0 || ( is_array( $catsel ) && count( $catsel )>0 ) || $w>=0 || $s!='' ) ) ) echo( 'no' ); ?>index,follow"/>

It helps a bit as only the main page and the archive is allowed to be indexed.

It's indedd the indexing robots who are 'misbehaving'...

Can I ban them (yahoo slurp robot ! grrr) ?
