This is the process of optimizing your website to "rank" higher in search engine results pages, thereby increasing the amount of organic (or free) traffic your website receives. The channels that benefit from SEO include websites, blogs, and infographics.
There are a number of ways to approach SEO in order to generate qualified traffic to your website. These include:
On page SEO:
This type of SEO focuses on all of the content that exists "on the page" when looking at a website. By researching keywords for their search volume and intent (or meaning), you can answer questions for readers and rank higher on the search engine results pages (SERPs) those questions produce.
Off page SEO:
This type of SEO focuses on all of the activity that takes place "off the page" when looking to optimize your website. "What activity not on my own website could affect my ranking?" You might ask. The answer is inbound links, also known as backlinks. The number of publishers that link to you, and the relative "authority" of those publishers, affect how highly you rank for the keywords you care about. By networking with other publishers, writing guest posts on these websites (and linking back to your website), and generating external attention, you can earn the backlinks you need to move your website up on all the right SERPs.
This type of SEO focuses on the backend of your website, and how your pages are coded. Image compression, structured data, and CSS file optimization are all forms of technical SEO that can increase your website's loading speed — an important ranking factor in the eyes of search engines like Google.
