Webmaster Read

I am posting in hopes that it may help someone else.

Yahoo has changed its crawling method and also added more crawlers and the way I read it for a short time there will be excessive amount of crawling of web sites for a period
of time
NetRange: 74.6.0.0 - 74.6.255.255
In effect may result in a higher cpu usage , and a higher number of hits also causing the pages to load slower ,

So as a Webmaster this is something you may want to be informd about

The links in this post explains what can be done to help slow The crawling down by using a delayed method

Thanks! In short, here's the relevant stuff from the links above:

There is a Yahoo! Slurp-specific extension to robots.txt which allows you to set a lower limit on our crawler request rate.

You can add a "Crawl-delay: xx" instruction, where "xx" 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.

Setting a crawl-delay of 10 for Yahoo! Slurp would look something like:

User-agent: Slurp
Crawl-delay: 10

This also helps keep the behaving search engine bots from getting banned with the Flood Blocker if you use "User-agent: *".

At one point Google said that they do not support that directive, but they have a way from their webmaster tools to set up a crawl delay. (Sorry if this particular info is outdated - have had both the robots.txt and Google set this way for quite some time - the old adage: "if it ain't broke, don't fix it!". LOL).

humm outdated It may be the only thing I know is several other sites I visit that show you visitors ip addresses are usually flooded with that range and yes it also sets off the Flood Blocker quite often
But if this helps any one it's a good thing,
I was wondering do you have a direct link to your Google
site map in your robots text file ?
Sitemap:http://YOUR SITE/sitemap.xml

The reason I ask Beginning in April or may befor all major search engines are able to read this method
and I have had some trouble getting Google to validate my site map

Any follow up on this ?
