There is a great variety of official rankings that help teach technology’s popularity. Rankings like the PYPL indexTIOBERedmonkTrendyskills or IEEE Spectrum’s differ in the measurements that they use. They all provide valuable information on the set of languages.

The most used are the PYPL index and TIOBE, which are based on the popularity of searches.

PYPL: PopularitY of Programming Language Index

The PopularitY of Programming Languages Index or PYPL is generated by the percentage of programming language tutorial searches on Google. It uses Google Trends as an information source.

The ranking of 2017 is shown below. The search frequency index is compared with the previous year:


Java maintains their kingdom, while PHP continues to fall. Python records remarkable growth.


One of the best known rankings, TIOBE (The Importance of Being Earnest) uses the biggest search engines (Google, Yahoo, YouTube, Wikipedia…) to nourish its algorithm. It shows each programming language’s uses.

The following table shows the year-to-year comparison to November 2017:
