why my keywords not working?

sir, there is one thing that make me very confuse.
when i check about my site from this site:

https://webpageworth.com/mediaghost.net

then it say like i dont have any keywords used, even no description:(
why is that so, isnt the tags i fill are the keywords? where can i find these keywords if these tags are not keywords? where i have typed about the description in its section but this site doesnt show? even i checked in few other related site.

my site is: https://www.mediaghost.net

please guide

thanks
