What seo future it is easy to lean.?

SEO does have a bright future, but it is an ever changing game. There is a lot of information and courses you can take online, but I would make sure you are getting information that is up to date (within the last few months) Courses from 2 years ago are mostly irrelevant today, and you can count on things changing again. The one thing that will always be true is this: write high quality original content and use proper site structure.
