SEO courses can either be free or paid. Free courses simply refers to the process of self-studying the various techniques in SEO by browsing instructional articles and videos in blog platforrms and social networking sites. You can subscribe to free newsletters too. Though, this type of training is time consuming and can be ineffective for some, especially for those who have no patience to organize things. You know, creating an outline is a must when you're studying the fundamentals and complexities of SEO. Some blog authors are even using terms that are senseless to you and as a result, you're reading an article without learning something. This happened to me four years ago. The first time I attended a seminar in SEO, I found it hard to understand how search engines work and why do they have these spiders who crawl on your sites. Yet, free courses can be also be fun. The fact that you don't spend a dime, it simply means you're giving yourself a chance to evaluate who you believe and why you believe them. The key here is patience.
Paid courses in SEO is, however, great in quality but expensive. You are paying for the company's services and for those lecturers as well. You can really learn something valuable once you attend a paid training yet you have no freedom to choose who to believe. The lectures are, of course, centered on their products, services and formula of success. Truth is; their SEO Plan might not work for your niche. There is a need to thoroughly study its basics to understand what correct techniques will work for you. For example, if the lecturer recommends you to use an autoresponder, are you sure you need this tool for your campaign? Do you have the budget to pay its monthly fee? To my understanding, it's still hard to say if you'll be needing an autoresponder as a beginner, unless you have 100,000+ customers worldwide or your company is as big as Apple.
