Research is an integral component of your extended essay. Including credible and relevant secondary source research in your paper is not only encouraged, it is required in most subject areas to score well in criteria A, B and C of the assessment rubric.
It is important to understand that not all secondary sources are created equally and that many sources you encounter on the internet are not suitable for an academic research paper such as the Extended Essay.
Your secondary research should be made up of credible, academic research done by respected professionals and academics in your field of study. You should also check that the primary research that you are gathering is credible.
There are many tool available to you to find suitable secondary and primary academic sources. Take time to explore these resources.
JSTOR (journal storage) is an online library of academic journals, articles, and books. JSTOR provides full texts searches of over 2000 academic journals in several different languages.
As a CCS student you have access to this very helpful tool for your academic research. It's very useful not only for your EE but for all your IAs and courses.
You will have a detailed JSTOR session with the school librarian and EE coordinator at the beginning of the extended essay process.
There are many other academic search engines and tool available online to help with your research. Again, it is important to make sure that your sources are credible and academic.
The first step in finding relevant and credible sources is understanding how to use Google Search properly.

Twitter, Facebook, Instagram - unless it is a post directly from an academic or business you are including in your EE
Sources that tend to be credible (but make sure to check them carefully):
academic journal articles found on credible academic search engines
sites ending in .edu or .org
sites from credible organizations and NGOs
governmental sites
primary data from the source (i.e business data or statistics on the site of the business you are researching)
