Chrome Auto Refresh Extension

Can anybody have any idea about the chrome auto fresh extension? What are the benefits of using them for SEO?

Search for Tab Reloader (page auto refresh) in Google, Click Add to Chrome next to the extension offered by tlintspr, Click Add Extension, Click in the boxes labeled Days, Hours, Minutes, Seconds, and Variation to change the refresh timer, Click the switch on to enable Tab Reloader.

There is no use.
