Evergreen keywords are keywords people search for all the time, not only for a short period. For example, "how to start affiliate marketing" is evergreen because people will keep searching for it every year. One way to find these keywords is to avoid trend topics and focus on problems people always have. Another way is to check if people have been searching for that keyword for many years using search trend tools. Evergreen keywords can bring steady traffic for a long time if the content is helpful and clear. What is the general opinion on this?
