What is SEO in Digital Marketing? Why It Matters in 2025?

If your business appears at the top of Google’s search results, more people will be aware of your business, and you’ll likely attract more customers.

So how do you get to the top of Google?

You can’t guarantee rankings on Google, but following SEO in digital marketing, you can rank higher in the search engine results pages (SERPs). 

In this blog, we’ll explain what search engine optimization (SEO) is, the types of SEO, how it works, how much professionals earn, and provide where you can learn SEO to rank higher in search engines.

What is SEO in Digital Marketing?

Search Engine Optimization (SEO) is a digital marketing strategy that enhances your website’s visibility and improves its page placement in organic search engine results, such as Bing and Google. The goal is to make your website visible when your customers search for terms related to your products, services, or business.

The higher your website ranks, the more traffic and leads it receives.

In short, SEO in digital marketing helps search engines locate and display your website to customers who are searching for your offerings.

Main categories of SEO in digital marketing

Before optimizing your website, you need to learn about the categories of SEO, because each category has a high quality to optimize your website for Google.

There are four main categories of SEO in digital marketing you need to focus on – on-page SEO, off-page SEO, technical SEO, and local SEO.

• On-page SEO is the process of optimizing your website’s content. This includes creating high-quality content and incorporating target keywords.
• Off-page SEO is the process of enhancing your website’s trust, authority, and reputation through backlinks.
• Technical SEO is the process of optimizing your website’s technical aspects, like page load speed, mobile friendliness, and structure.
• Local SEO is the process of optimizing your website to appear in local search results.

How you optimize your website for each of these four categories matters, too. You can get help from white hat SEO or black hat SEO.

Do the colors matter? Yes, the color shows the difference between them.

Black hat SEO uses spammy optimization strategies that try to manipulate Google’s ranking for your website.

Since Google penalizes sites that engage in unethical practices, so try out white hat SEO – techniques used for SEO optimization that comply with the guidelines and terms of service set by search engines. You can believe white hat SEO is the best way to go.

Why SEO Still Matters in 2025?

Some businesses wonder if SEO still matters in 2025 – especially with AI, voice assistants, and social media blowing up. The answer? Yes, it still matters.

Because people still search to find solutions to their problems. Whether it’s on Google, YouTube, or even Instagram — people are constantly looking for answers.

For instance, let’s take Google, it was the most visited website in the world in 2025. It processes over 158,548 searches every second. That’s 13.6 billion searches a day and 5 trillion searches every year.

It shouldn’t be a surprise because search engines are the biggest source of traffic for websites.

That’s the reason why businesses place SEO at the center of their digital marketing. But more importantly, it’s free. Unlike paid ads, you don’t have to spend money to stay visible and get traffic. Once you stop paying for your ads, it stops generating traffic – but SEO in digital marketing helps you stay visible once you build links or create great content.

Moreover, search is changing – voice search, AI-generated answers, and smart devices are shifting how SEO works, but it’s still key for getting traffic and leads organically.

In 2025, SEO is more dynamic – it’s about creating value and understanding how people search.

How Does Google Work To Rank Websites?

Well, if you want to improve your ranking in search engines, it’s crucial to understand how they work.

Sites like Google can provide their users with a list of result pages by crawling the web using “bots or crawlers”. These bots look for key signals like keywords, content freshness, and other signals, from every page they crawl and then add the information to Google’s Search Index.

This index is the backbone where Google stores a copy of what it finds on each published webpage. Whenever people make a search, Google serves up to show the best results. It uses over a hundred criteria (like relevance to the search query, freshness, authority, and so on) to determine which pages are best.

Google doesn’t just rely on the signals. It also measures user experience – how people interact with the search results. If people click on a particular result a lot, Google will rank the page. Similarly, if users click on a result and then leave the site immediately, Google may hurt the page rankings.

Finally, it’s important to note that search engines are constantly changing—and it’s your job to use SEO in digital marketing to stay up to date on everything.
