What is SEO?
SEO or search engine optimization is a process of improving a website’s ranking on search engines such as Google, Bing, or Yahoo. When people find something on a search engine then your website comes on the first page of SERP. The higher the rank of your website, the more visibility, traffic, and trust.
So, when someone asks, “What is SEO?”
The answer is: SEO is a technique to rank your website higher on the search engines.
In the DM course hub, we teach students that SEO is not about cheating the search engines, but rather producing high-quality, user-friendly materials that match the intention of searching.
Why is SEO important?
Now, we know “what is SEO”, the next question is – why does it matter?
The importance of SEO is explained by these major points:
Visibility increases: It helps your website appear in top search results, giving your brand more exposure.
Drive Organic Traffic: Unlike paid advertisements, it is free, attracting organic visitors who are actually interested in your offerings.
Creates reliability: high-ranked websites are seen as more reliable by users.
Cost-effective marketing: Once your site ranks, you continue to receive traffic without paying for every click.
Improves user experience: It focuses on fast-loading, mobile-friendly websites with relevant content.
In the DM course hub, we often remind the learners that SEO is a long-term investment. Businesses are ignoring their Risk in the Digital Marketplace.
How does SEO work?
SEO work is incomplete without knowing that search engines, such as Google, use complex algorithms that analyze hundreds of factors before ranking a website. Broadly, the SEO works in three stages:
- Crawling
Search engines send “bots” or “spiders” to scan the Internet. To understand the content, these bots crawl through the pages of your website.
- Sequence
After crawling, the pages are stored in a database called an index. If your content is relevant and customized, it is more likely to be indexed correctly.
- Ranking
When a user discovers something, Google looks at its index and ranks websites based on relevance, authority, and user experience.
In the DM course hub, we simplify these concepts for students and help them apply practical strategies that align with search engine guidelines.

Types of SEO
When searching for “what is SEO?”, the search engine finds information from its database, but how the search engine finds that is also important.
It is also important to understand its types because, without knowing that, we can’t work on SEO.
The SEO can be divided into three main categories:
On-page SEO
On-page SEO is a technique to optimize elements on our own website and attract organic traffic. Like meta title, meta description, keywords placement, images, and optimization of URL.
Creating SEO-friendly meta titles and details.
Examples: Writing a blog post with “What’s SEO” keywords naturally.
Off-page SEO
Off-page SEO is a technique to optimize elements outside of our own website and attract organic traffic to increase domain and page authority on SERP.
Like building backlinks from other prestigious websites, social bookmarking, ping submission, directory submission, and guest posting, etc.
Technical SEO
Technical SEO is a technique to optimize a website’s backend and server. It ensures your website loads quickly, is mobile-friendly, and has a safe HTTPS connection.
Fixing broken links, improving site architecture, and using structured data.
In the DM course hub, all three areas in our training are included with the study of real-world cases.
Major elements of SEO
To master SEO, you should focus on its building blocks:
Keywords: The phrase the user types in search engines. Example: “What is SEO?”
Elements: High-quality blogs, videos, infographics, and guides.
Backlink: Linking to other reliable websites pointing to your content.
User Experience (UX): Easy navigation, responsive design, and rapid loading time.
Analytics: Tools such as Google Analytics and Search Console to measure success.
It is a combination of technical information and creative strategy. This is why the DM course hub emphasizes both in its digital marketing course.
