What is SEO? It's a question more and more people are asking — the phrase "What is SEO" alone gets tens of thousands of searches every month. In today's article, Markdao will help you answer this question and decode why modern businesses increasingly turn to SEO services.

What Is SEO? The Simplest Definition of SEO

What is SEO? SEO stands for Search Engine Optimization — the set of practices designed to bring your website high-quality, free traffic from search engines such as Google, Yahoo, or Bing.

What is traffic in SEO? Traffic, also called visits, is the number of Internet users coming to your website. Quality traffic means visits from people who have a genuine need and are actively researching the products/services you offer — in other words, your business's potential customers.

Why Do Search Engines Matter So Much in SEO?

In practice, there are many ways to attract quality traffic: from social media (Facebook, Instagram...); from websites that mention you (news sites, etc.); from people who discover your site through referrals; from paid advertising; and most notably, from search engines.

Before digging deeper into what SEO is, you need to grasp the importance of search engines, because they are the key factor that makes your SEO service effective. Search engines can deliver an enormous amount of potential traffic to your business if you know how to exploit them properly.

In reality, hundreds of thousands of searches are performed on search engines every second — with Google alone handling 63,000 searches per second, which explains why Google is now the most powerful engine of them all. Search engines give you the chance to reach Internet users who don't yet know your business exists, or people who don't even realize they need your company's help.

Why Does Your Business Need SEO?

Now that you understand how important search engines are, it's time to learn why businesses — especially small and medium-sized ones — should use SEO services.

Getting your business widely known is no easy task. That's why one of the simplest and most cost-effective approaches is to have your website appear at the very top of the search engine results pages (SERPs). But according to expert research, not every position delivers the same results.

Specifically, research by Advanced Web Ranking shows that as many as 1/3 of Internet users click the #1 result, 15–16% click the #2 result, 10% the #3 position, 7% the #4 position, and 5% the #5 position. If your website ranks below position 5, you could lose 3/4 of the users who might have found your site. And 90% of users will never know your business exists if your website isn't on the first page of results.

So have you grasped what SEO's mission is? It is getting your website into the top 5.

What Is SEO — Understanding the Key Concepts in the Field

We hope that after reading Markdao's "What is SEO" article today, your business will truly understand SEO and be able to answer this question whenever anyone asks! In this overview of what SEO is, Markdao will cover: how search engines work, how the digital world that includes SEO will evolve, and who your website's visitors are.

How search engines work

Search engines generally don't disclose the details of how they operate. In fact, they are enormous pieces of software that have been continuously refined over many decades. Initially, engines evaluated and ranked websites using only a handful of criteria, but today Google, Yahoo, and Bing have upgraded and added hundreds of thousands of ranking factors.

Beyond mastering what SEO is, you also need to know which of Google's ranking criteria matter most, so you can easily identify problems on your site and propose fixes when rankings fail to improve on schedule. Although search engines don't publish their lists of ranking criteria, today's "What is SEO" article from Markdao will show you how to "survive" Google's demanding requirements:

• Manage your web pages well: to keep your SEO service safe and effective, you need to manage and understand every page within your company's overall website. Typically, small businesses that have just built a website tend to go learn SEO rather than focus on managing their pages. But in reality, managing your pages is how you gain the experience and deep understanding of your website and how to make keywords rank faster.

• Rely on research: beyond explaining information related to what SEO is, the world's professional SEO agencies also conduct studies based on the sites they manage or on sites built specifically for experiments... and draw conclusions about which criteria affect search rankings more or less.

• Follow the latest SEO news: you can follow the latest SEO information on sites such as AxNet, SEOMix, Webrankinfo, Search Engine News, Search Engine Watch, Search Engine Land, Abundance, Moz, Search Engine Roundtable, and Reddit discussion groups. These updates let you stay on top of the latest changes made by search engines.

Beyond understanding what SEO is, we need to know how SEO has developed and where it's heading?

What is SEO? SEO is not a concept that exists in isolation — rather, it exists within a system. The SEO field has been developing in Vietnam for over 15 years now, so simply knowing what SEO is isn't enough anymore; you should dig deeper into how SEO has evolved. Specifically, take a little time to look back and compare the digital world of 20 years ago with today. Twenty years ago, people accessed the Internet mainly from desktop computers; now it has evolved into laptops, tablets, mobile phones, even TVs and apps.

Beyond Google, Yahoo... and other "classic" search engines, what other search tools should you pay attention to in SEO? These are the websites that have become genuine alternatives to search engines for certain topics — for example, Amazon is a search engine for products to buy, YouTube for video clips... And in the future, Facebook could also become an alternative to search engines.

Beyond the evolution of search engines, SEO itself has branched in many directions. Specifically, in the future you may not search "what is SEO" but instead research local SEO, multilingual SEO, how to write SEO-standard content, and technical approaches such as log file analysis — which helps study search engine behavior on a website to find the best optimization methods for improving keyword rankings as fast as possible.

Markdao analyzes all of this to show you that the answer to the question "what is SEO" truly isn't as simple as its definition. Beyond that, to help you understand more when optimizing SEO or using an SEO service: you shouldn't fixate on SEO alone but pay attention to other areas such as social media, and you should regularly follow news about search engine algorithm updates to avoid cases where algorithm changes hurt your rankings.

Who are the visitors coming to your website?

Two types of visitors regularly come to your website: Internet users and search engine robots. You need to cater to both, because both are important and bring enormous benefits to your business. So what should you do to get more value from these visitors — or "visitors" in SEO terms? To optimize your SEO service, you need to know more about your website visitors: who they are, what they come to your site for, what they like about it, which content interests them most, and what devices they usually use to access it.

What Are the 3 Foundational Concepts You Must Know in SEO?

When you dig deep into what SEO is, you need to know the 3 most common concepts in SEO: Technical; Semantics; and the Link System.

What is the technical side of SEO?

When doing SEO, you need to pay attention to technical issues — specifically, the website and how it is built: does the page load quickly, is the site mobile-friendly, are all the necessary Heading tags present, have the title tag and meta description been implemented; make sure no pages return 404 errors — if you don't understand these errors, see the article The 10 Most Important HTTP Status Codes in SEO Services. In addition, you need to make sure your website has a complete, clear menu so that visitors can reach every page they want.

You also need to ensure there is no duplicate content between your website and other sites, or between your own pages. If robots detect duplication, they will push your website out of the results. On the other hand, don't forget to keep optimizing pages that Google has already indexed or that rank highly — otherwise they will slowly slip down the rankings without you noticing.

Why do you need to care about the technical side of SEO? Because you must make sure the website is search-engine-friendly — only then does the work of SEO become easier.

‍

Why do semantics matter in SEO?

You've grasped the meaning of the technical side of SEO — now let's move on to the meaning of the content published on your website. Don't assume that meeting Googlebot's criteria is the end of the story, because robots have been optimized to the point of detecting whether content actually matches the topics your website intends to cover. More importantly, the content on your website exists to serve Internet users. If they find your site unattractive, rambling, or off-topic, they will leave and go to another provider — possibly your competitors.

So how do you evaluate content quality on a website in SEO? It comes down to: are you getting traffic from search engines; how often is new content published on the site; how is the content organized and structured; and does the content use language that is clear and easy for users to understand?

When talking about optimized content, you can't skip keywords — they are the single most important element in any SEO service. The higher a keyword ranks, the greater the share of potential customers finding you. And you can't ignore your competitors — the people running the same keywords as you, how they run them, and where they outperform you — so you can find ways to improve your own SEO effectiveness.

‍

What is the link system in SEO?

The third pillar concept Markdao wants to cover in today's "What is SEO" article is the system of links. Beyond technical quality and content, your website needs authority, and that authority comes from having many other websites talk about yours and link back to it. But these links need to be natural — if you use shady tactics to accumulate links, Google will "blow" your website out of the search results.

What should you watch out for with the link system in SEO? Make sure your website is cited by reputable sources, on topics related to yours, and in the most natural way possible. "Natural" here means you can ask for or purchase service packages from reputable websites, such as news outlets — or you can build your own satellite sites, publish content related to your main website, and then insert keywords that link back to your site.
