Alexa Rating

I know that you that the more traffic you get the lower your rating will be. But say that your website have a rating of 60,000 and the next week more people come on the site than usual, so your rating drops to 55,000 BUT the next week the website doesn’t receive any traffic so will the rating increase back to 85,000 or will it just stay at 55,000


it raises and lowers. My site is hanging out at 37k and goes up to 38 and back to 37.
