Rangers remain unbeaten this season after a goalless draw against Brighton in midweek took them a point clear at the top.
Yeovil, by contrast, are in the bottom three and have yet to pick up a point at home, but Hill knows a shock will be on the cards if Rangers take them lightly.
"Teams will raise their game against us and that is going to be important," said the defender.
"There is always that fear in the back of your head that they have got to win sometime. We have got to be right on our game.
"It is probably one of our biggest games of the season so far, in terms of going there against a so-called smaller team who will want to do us over.
"I am sure the other teams will be looking at us to see how we come through it."
