advertising - Difference between Ad company statistics, Google Analytics and Awstats on adult sites -


i have problem. have web page adult content , several past months had ppc advertisement on it. , i've noticed big difference between ad company statistics of page, google analytics data , awstats data on server.

for example, ad company tells me, have 10k pageviews per day, google analytics tells me, have 15k pageviews , on awstats it's around 13k pageviews. system should trust? should write own (and reinvent wheel again)? if so, how? :)

the joke is, have web page, "normal" content (mmorpg fan site) , numbers +- equal in 3 systems (ad company, ga, awstats). think it's because it's not adult oriented page?

and final question, totally offtopic, know ad company pays per impression , don't mind adult sites?

thanks answers!

first, should make sure not mix »hits«, »files«, »visits« , »unique visits«. have different meaning , called differently. recommend definitions if confused terms.

awstats has correct statistics, because has access access.log web server. unfortunately, cached site (maybe cached browser, proxy isp or own caching server) might not produce hit on web server. if site served caching hints don't enforce revalidation , running own web cache (e.g. squid) in front of site, number considerable lower, because measures work of web server.

on other hand, google analytics able count requests users haven't blocked google analytics , have javascript enabled (but count pages served web cache). so, count can influenced user, isn't affected web caches.

the ad-company counting number of requests site (probably based on access.log). so, counted there, add must not cached , must not blocked user.

so, can see, it's not easy single correct value. long use measured values in comparison previous months, should @ least (nearly) correct rate of growth.

and porn site serves high amount of static content (e.g. images disk) , of web servers @ serving caching hints automatically static files. mmorpg on other hand, might consist of dynamic scripts (php?) don't send caching hints @ , web servers aren't able determine caching headers dynamic content automatically. that's @ least explanation, without knowing application , server configuration :)
