Robots =INDEX,FOLLOW or Robots =ALL

Do search engines have preferences

[caine]

I started using the <meta name="robots" content="all"> tag, then from reading i now use content="Index,Follow">.

Why do some designers use "all" as opposed to "index,follow" or vice versa, is it because certain search engines prefer one or the other, or a lack of standardisation ?

If any one knows, i would appreciate a reason.

The ALL directive is really a kind of shorthand for INDEX,FOLLOW. Take a look here, Using a Robots Meta Tag [searchengineworld.com] for more info.

Thanks NFFC.

I've read that page. But if it's just a shorthand version, i'm going to stay with INDEX,FOLLOW
