SEO metatag NOOPD and NOODP Which one to use

Question

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">

Answer 1

simple answer the best meta tag that google can understand is NOODP it  prevents the alternative description from the ODP/DMOZ from being used
