Start by checking the date of the information, old information may usually be inaccurate/outdated. Examine the author of the source, their reliability. Have a look at reviews from that source too, make sure to stay alert of third party vendors. Approximately 63% of all data breaches were attributed to a third-party vendor so it’s important to cover that. Finally, check for non-credible features such as bad grammar, poor design, spelling problems, broken links etc.
