I went back to this thread when it's just a week ago when we're discussing about marketing and exposure. Now, you've launched your campaign and that's a good start and having a guarantee of 4 week. But, usually with that short term of run, they won't give that much effect. Maybe there's a little but to have a stable effect on it, just like the other casinos, they're running it for so long. Anyway, you still need to evaluate the effect of it after all and wishing you good luck on it.
You dont know if they are just testing out if it was effective or totally just an enough amount for them to start up their marketing which we couldnt really make
out conclusions but having suggestion about long term exposure on this forum would be a good idea but dont anticipate nor expect guaranteed positive effects
because it would really be varying on the site itself from overall aspects or factors.
