What is the difference between these two Robots?

<meta name="robots" content="index,follow"/>
<meta name="robots" content="noarchive"/>

Please suggest me friends, i know the first line of script, but i want to know the below script...

Why don't you try googling for it..?

first result says "noarchive" tells google to not store a cached version.

If you're going to use all three tags, you should include them in the one meta tag, not have two separate ones. ie

<meta name="robots" content="index,follow,noarchive"/>

<meta name="robots" content="index,follow"/> - it means that spider will index whole your website, if you change to noindex, spider will stop only on this page

<meta name="robots" content="noarchive"/> - google will not show cached link is search results.

Thanks for telling the differences.
