By changing the meta data with the NOODP and NOYDIR will there be a noticeable improvement in the SERP?

I dear,

Thanks to make this question.
I also looking answer of this question. 
Lots of SEO professionals use both (NOODP and NOYDIR ) tags in meta,s. what is effects of these tags on your site?

Sometimes, if you are listed in DMOZ (ODP), the search engines will display snippets of text about your site taken from them instead of your description meta tag. You can force the search engine to ignore the ODP information by including a robots meta tag like this: <meta name="robots" content="noodp" />.
