Sherry,
Questions such as this one will get a better answer if posted to analytics@ public list. From the discussion is not clear what users wish to measure but I am providing some links below that might help.
Alexa ranks sites according to other sites, which we obviously do not do. If a ranking fluctuates a lot that tells you Alexa's methodology doesn't work for your site (likely you get too little traffic).
We have pageviews and unique devices measures for all projects of a certain size. Referral information ("where does traffic come from?") is also available but a bit harder to get. Looking at sources of publicly available data you can see wikivoyage is pretty static when it comes to growth.
English wikivoyage pageviews are mostly constant, around 60.000 daily, mobile makes about 20.000 of those. If you zoom you can see that number is slightly higher in August but really within the same order of magnitude.
English wikivoyage daily unique devices, they have about 15.000 devices per day.
About 300.000 devices per month:
Thanks,
Nuria
