Earlier quoted context omitted.
We get a lot less traffic during the summer months (school isn't in session) and towards the end of the year for the holidays... but we do get quite more traffic than our quantcast page suggests. It does look like I was totally full of my own shit though, we're clearly not that big when it comes to the other Django sites out there.
It looks like an average of 50,000 monthly uniques when school is in session. Do you mind sharing your actual numbers? And can you hazard a guess why Quantcast is so inaccurate? It seems curious, considering you have their javascript tracking code on every page of your site. If their tracker is so broken, why use them and not Google Analytics?
This comes up with some frequency. Uniques daily * 30 != uniques monthly, after all, if you undouble on a monthly basis and you get 30K visitors each day and they're all different it looks like you have a cool 900K uniques monthly. But at the same time it means you are completely not sticky! All your users are replaced by new ones every single day.
A better measure is uniques daily, daily growth in uniques and compare that with your uniques monthly. If you're doing it right you should see (30average repeats) + (30average growth)
Those are figures that you can do some planning on. Monthly uniques does not do anything other than look good on paper. Bad websites look even better :)
