To learn SEO, web development and many other areas that I like, I always focus on doing a couple of courses and also supplementing with at least 1 book a month. The truth is that I feel that this habit of reading is losing, and it may be much more useful than you think. It does not matter if it is about marketing or other things, I visit the
WordsLovers website and look for things that interest me in its categories, this in order to be able to distract myself or learn indirectly from many things. The truth is that I recommend it, it is always good to be able to invest time in this type of thing.
