What Is SEO Content?
To understand what marketers mean by SEO content, it’s helpful to break down the phrase into its component parts:

“SEO” refers to search engine optimization, or the process of optimizing a website so that people can easily find it via search engines like Google.
By “content,” we mean any information that lives on the web and can be consumed on the web (more on the various types of content below).
So, putting these two concepts together: SEO content is any content created with the goal of attracting search engine traffic.

I’m not going to tell you everything you need to know about optimizing your content for search engines here; that’s a whole ‘nother guide. But here’s a super-quick refresher on what you’ll need to do in order to SEO your web content:

Keyword Research: If you want to generate traffic through search, it’s best to do keyword research before you start writing. This way, you can focus on keywords for which a certain amount of search volume already exists – in other words, write toward topics (or find keyword niches!) that people are already searching for information about.
Keyword Optimization: Know where and how to use keywords in your content for maximum searchability.
A Quick Word on Intentions
It’s important to keep in mind that if search engine traffic is your only goal, your results will probably suffer. In order to please both the search engines (who will reward you with high rankings over time) and potential customers and return visitors, you need to offer value above and beyond search engine optimization. In other words, don’t produce “thin” content that ranks and get clicks, but doesn’t provide any additional value to the search engine user. Sites that promote “thin,” low-value content run the risk of being penalized by Google; they also tend to have high bounce rates and low conversion rates.
