Freetechbooks.com Overview

Freetechbooks.com is a popular website that lists free online computer science, engineering, and programming books, textbooks, and lecture notes. Its website title clearly conveys the goal of the website, which is to provide a large database of free educational resources to anyone who may need them.

The website is hosted by Liquid Web, L.L.C, US hosting and has a top-level domain .COM. It has a relatively high number of unique users per day - 2039, and receives 5097.5 pageviews. Its estimated site value is 94900 US dollars.

The website is a great resource for students, educators, or anyone interested in learning about computer science, engineering, or programming without the burden of having to pay for course material. As described on their homepage, all the books, textbooks, and lecture notes are legally and freely available, making it an ideal platform for people who cannot afford to pay for such materials.

The website has a simple and straightforward interface, making it easy for users to navigate and search for the resources they require. Its homepage provides tabs- Home, Books, Textbooks, Notes, Reviews, Discussions, and About. The fact that the website has a review section makes it more reliable as people can share their experiences and thoughts on the resources that they have used.

The content available on the website is aimed at providing quality educational resources to its users. Its mission statement is clearly defined, and its educational focus sets it apart from other similar sites. It is also a family-friendly site where users can learn about computer science and programming without being exposed to potentially objectionable material.

However, there is room for improvement as the website scores poorly on the Google PageSpeed Insights website speed test with a score of only 47. This means that the website takes longer than usual to load, making it less accessible to users. Improved website speed could lead to an increase in user satisfaction and traffic.

In conclusion, Freetechbooks.com is a well-structured website that provides a valuable service. Its simple design and focus on quality resources make it an excellent resource for anyone interested in computer science, engineering, or programming. Although it needs improvement to improve its loading speed, the website's excellent content makes up for it.
