robot.txt on landing page

[Blue_widget]

Do you put robot.txt on your landing pages?
I've read some opposite thoughts on that, does anyone have some real experiments with that?

Thanks!

I don't understand the question. Put robots.txt on landing pages? Do you mean use robots.txt to keep them out of the organics? Often I do, depending on whether the page is static or dynamically generated (although if I'm going to do that, I'll probably use the robots meta tag and NOINDEX it. And I'll *always* NOARCHIVE it)

If you have a special offer, you might not want it to show up in organics with a special price that someone will want to hold you to down the road. Also, PPC landing pages often have different goals than organic landing pages.

That's what I meant, thanks.
Is there any downfall in not indexing landing pages?
any impact on the Quality score?

Not in my experience.

You do want to use NOINDEX though and not robots.txt, as the bot will need to see the page to see if there are issues with it.
