Google Updates Robots Meta Tag Page To Specify Multiple Meta Tags Are Ok and How GoogleBot Will Process Them

Google updated the docs to specify you can create a multi-directive instruction by combining robots meta tag directives with commas or by using multiple meta tags.

For situations where multiple crawlers are specified along with different directives, the search engine will use the sum of the negative directives.

<meta name="robots" content="nofollow">
<meta name="googlebot" content="noindex">

The page containing these meta tags will be interpreted as having a noindex, nofollow directive when crawled by Googlebot.
