為了進一步提升 TIOBE 排行的專業性，本月增加了 16 個新的搜尋引擎，這些搜尋引擎絕大多數來自中國和美國。這些搜尋引擎的列表請看這裡。
在增加了 16 個新的搜尋引擎後，C 和 Objective-C 呈大幅下降趨勢，分別下降了 1.65% 和 2.17%；而 Go 語言則從 42 名提升到 26 名,php上升到了第5位
TIOBE 釋出8月份的程式語言排行榜，榜單如下：
In order to professionalize the TIOBE index further, we have added 16 extra search engines as of this month. Most of them are from the US and China, but there are also Japanese and even a British and Brazilian website in use now. An overview of all search engines used can be found on the TIOBE index definition page. The new search engines will count only for a marginal fraction of the total. Next month we will complete the number search engines together with an explanation why these are chosen.
C and Objective-C are the biggest victims of adding the 16 new search engines. They go down -1.65% and -2.17% respectively. Winners are Go (from 42 to 26), LabVIEW (from 100 to 49) and Openedge ABL (from 129 to 57).
