no robots.txt

[textex]

Will having no robots.txt effect the ability being spidered?

Never really had a problem before, just trying to figure out why pages may have been dropped.

No. If robots.txt doesn't exist, then it's treated as if the right to spider to given.

I have robot.txt. and got dropped this weekend from yahoo..

Unless you told Yahoo/Slurp to stop spidering your site, it has nothing to do with you being dropped.

Being new at this, I’ve been adding a page a day and the only thing I change was the robot.txt , with was restore to last week version and added a commercial software to monitor my click. Well now I know that it was’nt the robot.txt
Thanks Sanenet

For the record, the format should be robots.txt

Have a look at the robots tutorial [searchengineworld.com]

You only need a robots.txt file if you want to provide some control on which parts of your site is not spidered and by which spider. Often you won't need a robots.txt file at all.
