Types of SEO?
Generally, there are 3 types of SEO that you should be aware of: On-Page SEO, Off-Page SEO, and Technical SEO. Let’s briefly look at each of them:
On-Page SEO: These are the things that you do on your website itself – Content, Meta Title, Meta Description, Headings, Internal Linkings and so on.
Off-Page SEO: These are the things that you do outside your website in order to build a good reputation and become an authority figure and establish relationships – e.g., getting links from other sites, social mentions.
Technical SEO: (Sometimes considered separately). These are the technical support parts that help the search engines to crawl, index and understand your website. They are the support for On-Page and Off-Page.
Each of these is a different layer and they are all very important and work together. You cannot be dependent on only one. A successful website uses all three — On-Page, Off-Page, and Technical SEO — together. They work like the engine, fuel, and steering of your digital presence.

Outcome: As a matter of fact, these tactics might bring a quick traffic flow at the very beginning; however, the risk is extremely high — the websites might face penalties or be taken off the search results.

Most of the marketers use it to keep themselves in the game, but it is still risky because what is allowed today might be punished tomorrow.
Outcome: The rankings can be elevated for a brief period of time. But in case of search engines updating their algorithms, it may become risky.
