"It makes nice viewing but we're not getting carried away," he told BBC WM.
"It's good times at West Brom. The fans are very happy. But the further we go the more respect we'll get from other teams and the harder it will be.
"Maybe we can win five or six in a row then see what happens."
West Brom travel to The Liberty Stadium on Wednesday to face Swansea City, and Long believes it could prove a feast of football for the neutral.
"Swansea are a good passing team too and that should make it a good game to watch, we know we'll get nothing easy," he added.
"But, if we work as hard as we did when we won at Wigan and at Sunderland on Saturday then we'll have a chance of winning.
"We play good football, we're hard to play against and that's a recipe for good things."
