Hello guys, I'm not sure if this is the correct section to post this problem in. Mods, please move to the appropriate section if this is the wrong place to be in.

Ok, here it is, ever since I have changed from 2.1.7 to 2.3.3 IPB boards, my bandwidth has gone thru the roof. I used to go thru about 30 gigs a month, know I go thru 120 gig, and the google bot eats up about 85 gig, the yahoo bot another 10 gig.

My limit is 40 gig and each gig after that is $4 a pop.

Now the problem, I rank very high on each search engine, and dont want to lose it, but I need to control the amount of bandwidth the bots go thru. I dont want to ban them altogether either as i will lose my search engine ranking.

I found this in regards to the yahoo bot ... rp-03.html

You can add a "Crawl-delay: x.x" instruction, where "x.x" is a delay value between successive crawler accesses. If the crawler rate is a problem for your server, you can set the delay up to 5 or 10 or a comfortable value for your server, but we suggest you start with small values (0.5–1), and increase as needed to an acceptable value for your server. Larger delay values add more delay between successive crawl accesses and decrease the maximum crawl rate to your web server.

For example, a robots.txt rule to set a crawl-delay of 5 for Yahoo! Slurp looks like:

User-agent: Slurp

Crawl-delay: 5

A shorter delay value of 0.5 would look like:

User-agent: Slurp

Crawl-delay: 0.5

Now, I have a VPS server for my site, so my questions are as follows.

What value should I use, and is there is a similar thing I can do for a google bot?

Or is there another way to reduce the amount of bandwidth the bots consume?
