Random Riddle: Looked Down Upon

Upon one’s entry, I make one feel invited
Though my greeting goes unrequited

By all of your guests, I’m looked down upon
Receiving no attention as their visit goes on

Stomped upon as they exit, I’m not dejected
In fact, I remain totally unaffected

With my positive message, seven-letter
One might think I would be treated better
