SEO is simple, there's no need four long, convoluted courses. You just need...
- find keywords you can easily rank for with the resources (money) you have at your disposal that have commercial intent (so you can make money) and low competition (you want to rank for those keywords ASAP, not after 2 years)
- create good content (content that addresses the questions / topics of the keywords you've found) in detail so that when people land on your page they go like "WOW! This dude really knows what he's doing. Imma buy from him"
- optimize your site for google so that it knows which keywords to rank you for, and on what spot. This means... 1) use your main keyword in the title of the page you wish to rank for; 2) use the keyword you want to rank for as an ALT tag in the first image on your page; 3) add an image that's relevant to every 300-400 words of content (or to each subtopic of your content); 4) create sub-headings (H2, H3, etc) for long tail keywords (5+ long words keywords that are very specific); 4) make all pages of your website load in less than 2 seconds
- get quality backlinks to the homepage of your domain and to the pages you are trying to rank for to boost the authority of your domain (authority domain names usually rank higher) to push your website up the rankings. By quality backlinks I mean backlinks that 1) come from websites in the same niche / industry as yours; 2) the websites where your backlinks come from get organic traffic from google; 3) the backlinks are in content (inside of the article) instead of in the sidebar or the footer of the website; 4) (not required but helps) the websites you get the backlinks from have good authority (DA);
- get lesser quality backlinks to the quality backlinks you've gotten in the previous step so you can get those backlinks indexed and boost their authority which, in return, will make your quality backlinks even stronger
- add fresh content to your website regularly (try at least once a week, but the more often, the better) and acquire new backlinks monthly until you stabilize your rankings in top 3 spots of google for your target keywords
- stay updated on the new algo changes that google rolls out and adjust your website / content accordingly where needed
