Info about BiTLOG



How is information obtained.

Bitlog uses a 'trick' to obtain information, by placing a 1x1 pixel image but actually extracting information because the image reference is a php program.

There are 2 kinds of possibilities.
-Information comes from a PHP page
   -we know the refering page (if not blocked).
   -we know the requested page.
-Infomation comes from a HTML page
   -we know requested page.

-In all cases we can determine browser-agent

The browser agent is used to determine whether a robot 'crosses' our website.
If the user cannot be found in the cookies, place a cookie and mark time/ip/agent.
If the user is found, check whether the same page is requested within the 'no-register' time,because it is a page refresh or so.
If it is a new page, add the page with the cookie number.
Every visit is registered this way.
What might be the problems
The only problem is when a user has his cookies blocked, or wipes them after a certain period.
If cookies are blocked, every page request is registered as a visit.
If cookies are wiped, a subsequent visit will be registered as a new visit.
Since in general few people block cookies from the same website, there are only few discripancies.
Same goes for referers. Only few browsers block refererers
What is the difference between distinct and non-distinct
Distinct means unique. For BitLog it means every unique cookie is counted once in a certain period.
This in contradiction to non-dsitinct where you count every visit as a visitor (not repeated page requests).
So if we count visitors on a day and 1 visitor comes back say 3 times, he is still counted as 1 unique visitor. Same if the period would be 1 month.
Only the day praphic uses non distinct visitors because the graphic might give unpredictable results if an other method was used. Here new visits are counted, but still 1 visitor 1=1 hit for the day.
How acurate is bitlog
The method used by bitlog is very accurate, but requires every page on the site to have the reference to bitlog via the <img src=bit.php .......> reference.
How to maintain BitLog

For the country references BitLog uses a quite big table. This table has to be updated from time to time.
Use the information from any site that has this info readily available, like www.ip-to-country.com>
Obtain the delimited version. See readme for instructions.
How long to keep data Since bitlog logs every page visit the table migh grow huge after a long time.
It is not advisable to keep the data longer than 2 years. The admin section lets you delete the old data.
Make sure you backup your database on a regular basis.
