Google has updated to maintain accurate meta tags to understand more accurately crawl, index and return sites in search results.
Here's how Google would interpret meta tags of this sample HTML page:
Title utilized by Google, can be shown in our search results
description content : utilized by Google, can be shown in our search results
revisit-after content=14 days not utilized by Google or other major search engines
verify-v1 content optional, for Google webmaster tools
While the use of a description meta tag is optional and will have no effect on your rankings, a good description can result in a better snippet, which in turn can help to improve the quality and quantity of visitors from our search results.
