Another is here:


Here is how the ratings are calculated.  So every time you open up
'Programming Perl' to look up something, or run 'perldoc -f', TIOBE
does not factor that usage into their calcuations.


The ratings are calculated by counting hits of the most popular search
engines. The search query that is used is

+"<language> programming"
This search query is executed for the top 6 websites of Alexa that
meet the following conditions:

The entry page of the site contains a search facility
The result of querying the site contains an indication of the number
of page hits
Based on these criteria currently Google (32%), YouTube (10%), Yahoo!
(3%), Bing (3%), Wikipedia (16%), Blogger (32%) and Baidu (3%) are
used as search engines.
