The study was carried out with 45 web pages reached as a result of scanning the relevant keywords in the ‘Google’ search engine, eliminating repetitive web pages, and applying the inclusion and exclusion criteria. Content analysis, readability calculation, and statistical analyses of the data obtained from web-based information sources were performed. It was observed that the web pages of various companies, academic texts, and the contents prepared by experts in the field of education were more common among the data sources. It is noticeable that the focus of the topics addressed in the texts is game-based learning. While the highest number of data sources are in the medium difficulty category according to Ateşman’s readability formula, they are at the educational reading level according to Çetinkaya-Uzun’s readability formula. According to both formulae, the average readability of journal/book/newspaper sources is statistically higher than that of company and university sources. In conclusion, when an evaluation is made in the context of lifelong learning, it can be said that our education life continues continuously. Therefore, our different life roles have always pushed us to seek learning. One of the sources in our learning journey is web pages. In the context of the research, it was concluded that it is essential for parents, teachers, and children in the target audience to understand the texts on web pages.
