The Reds have kept clean sheets in their last two games and Johnson is hoping that has given the team something to build on as they look to get their season back on track.
"We have had two clean sheets on the spin now and hopefully we have got a platform to build on when we go to Blackburn," said the defender.
"We know that we haven't been picking up the results that people associated with this club expect, but there was no better place to start picking up points than at Goodison Park last weekend.
"Now we want to get on a good run. The next game is all that we can worry about but we want to be pushing up the table and hopefully we have made a start."
