What Is SEO?

Before we discuss the difference between SEO and SEM, let’s look at each strategy separately. What is SEO, exactly?

Search engine optimization is an organic search engine marketing strategy. Not many people realize that SEO falls under the umbrella of SEM.

SEO involves optimizing your website content to ensure consumers find your brand online. Your website can appear as consumers search using specific keywords. You can ensure your content appears for those search queries to reach your ideal customers.


In order to improve your organic search engine rankings, you’ll need to consider four different types of SEO. These include:

  • On-page SEO
  • Off-page SEO
  • Technical SEO
  • Local SEO

On-page SEO involves optimizing your website content for specific queries. For example, you can add a target keyword to each page or post on your site. The target keyword should appear in the:

  • URL
  • Page title
  • An H1 header
  • Opening and closing paragraphs
  • SEO title and meta description
  • Image file name and alt text
  • Body text

The SEO title and meta description appear on search engine result pages (SERPs). It’s important to make sure the title and description are compelling enough to encourage clicks. As more people click on your content, your clickthrough rate will improve.

A high clickthrough rate could boost your organic SEO rankings.

Off-page SEO involves factors outside of your website. For example, it’s important to generate backlinks. These links appear on other websites before directing people to your website.

Backlinks are one of Google’s most important ranking factors.

Technical SEO involves the backend of your website. For example, you’ll need to provide the best possible user experience (UX). A positive UX indicates your site is easy to use and navigate.

If your site is easy to use, people will linger on your pages, increasing your dwell times. High dwell times can also boost your rankings. 

It’s also important to make sure your site is fast, mobile-optimized, and secure. Google will look at the mobile version of your site first before crawling and indexing your content.

Local SEO can help you reach local consumers. You can update your Google Business listing to strengthen your local strategy. Generating positive reviews and creating localized content can help, too.

The Benefits

A strong search engine optimization strategy can help you rank at the top of SERPs. Ranking at the top for relevant queries can help you generate:

  • Brand awareness and recognition
  • Brand trust and loyalty
  • Website traffic
  • Credibility and authority
  • Leads and sales
  • A stronger ROI

Consumers will see your website before a competitor’s during relevant searches. As a result, SEO can also give you a competitive advantage.
