If you have an META tag instruction for robots, do you need a robots.txt?
It depends.
At the very least, you should put an empty robots.txt to cut down on 404s on your site.
Using META tags allows you to control how robots index or follow links on your pages.
Using robots.txt restricts access to files (text and binary), as well as directories.
I have wondered for the past year if there may come a time when spiders will not visit sites without a robots.txt file. The reasons are the increasing amount of privacy laws around the world. With email it's opt in, with any information we gather on our sites it's a published privacy policy. In the future, new laws may require web spiders to get an opt in (robots.txt permission slip) before they visit and list pages. I'm just commenting on the way the wind is blowing these days. I'm sure many people disagree with me, but I don't think it hurts to tell all robots it's ok to spider their site. We've added this information to all our domains and sub domains over the past few month. I hope to hear some more comments on this.
