The main difference is that search engine optimization (SEO) focuses on improving a website to get traffic from organic search results. Search engine marketing (SEM), on the other hand, aims to drive traffic and visibility from both organic and paid search.
Keep the other way:
Google's search results are divided into two main categories: paid search results and organic search results. The goal of SEO is to rank your website in organic search results.
You can also find your website with every click (PPC) in the paid search area.

So yeah, SEM is a broad term that includes SEO and PPC, which means that SEO falls "under" SEM's umbrella category.
SEO vs. SEM: Main Features
SEO is the process of permanently optimizing a website to rank in organic, unpaid search engine results pages (SERPs). Google uses 200+ rating signals in its algorithm. That said, SEO can be divided into four main subcategories: on-page SEO, off-page SEO, technical SEO, and user interaction signals.
On-page SEO: This is where you optimize your website around keywords that your target customers find in Google, Bing, and other search engines. For example, on-page SEO's best practice includes your keywords in your title tag, meta description, and web page URL.
Off-page SEO: Off-page SEO is about gaining trust and authority signals from other websites. It involves building high-quality backlinks to your site. But Google can also use other off-page signals to increase your site's authority, such as e-A-T and social media sharing.
Remember: SEM is a high-level term that includes SEO. So everything I have just said for SEO also applies to SEM. But in addition to SEO, SEM also includes PPC. And PPC is a field that has its own set of features, best practices, and much more.
Bidding: Whether you use Google ads or Bing ads, paid ads in search are about bidding. With PPC, you bid on specific keywords. And when someone searches for his word, your ad appears.
And when someone clicks on your ad, you pay for whatever you bid. When someone clicks on your ad, you pay the amount known as the total cost per share (CPC).
Quality Score: Quality Score is a very important Google advertising metric. It is a way for Google to gauge whether your ad is looking for anyone.
It calculates a Quality Score based on a combination of clickthrough rate, the quality of your landing page, and the overall Quality Score of your Google Advertising account. And if your ad has a high-quality score, you'll get a discount on every click.
