I was adding few more additional metatags for improving SEO of the website I am working on, however I have never used NOOPD or NOODP meta tags before and on searching about these metatags, I am a bit confused which one to use and what is the difference between these two?
so I was wondering which one is better or is there any difference between these two at all?
<meta name="GOOGLEBOT" content="index, follow, all, noopd, noydir">
or
<meta name="GOOGLEBOT" content="index, follow, all, noodp, noydir">
You should use noodp
, because that is one of the meta tags that Google understands. As described at that page, this tag "prevents the alternative description from the ODP/DMOZ from being used".
