Use the CRAAP test regularly. At a certain point, it becomes automatic and you will develop a better intuition for the reliability and usability of information. The CRAAP test can still help you to explain why you think certain information sources are suitable or not.
Use the Tools button in Google Search and then limit the period within which you want to search in order to search specifically for current information only.
It is easy to get bogged down in long-winded searching. Make sure that you are focused on a specific search question. That also helps you determine the relevance of information!
Beware of filter bubbles: when search results are personalized (for example in Google), you will not get to see certain information. Do try to use another search engine such as duckduckgo to avoid this problem.
Use a consistent way to refer to the sources you use, for example IEEE or APA style. This way, the reader of your documentation (e.g. a team member, a client, or a team that builds on your work) can more easily check whether the used sources are suitable, which makes your work more reliable and more convincing.
