What is Search Engine Optimization (SEO)?

SEO stands for Search Engine Optimization, which is the process of optimizing a website to align with how search engines work. This enables search engines to easily understand what the website is about and how it provides valuable information to users.

The goal of SEO is to ensure your website appears at the top of search results, resulting in an increase in organic traffic. This means a surge in website visitors without the need for excessive promotional spending. Consequently, the likelihood of your online business succeeding grows significantly.

How SEO is Important for Online Businesses?

SEO marketing is the process of online marketing that focuses on optimizing websites through SEO strategies. The goal is to ensure that our website or online media (such as images and videos) appears at the top of search results. The higher the ranking—preferably number one on the first page—the better.

Today, search engines like Google, Yahoo, and Bing are among the most widely used websites in the world. They have a significant impact on consumer behavior.

14.6%

Imagine if, when people search for products or services related to what you offer, your website appears at the top of the results. This could significantly enhance your business opportunities and create remarkable Brand Awareness.

It’s no surprise that SEO is a crucial strategy for online businesses, as it significantly boosts website traffic.

Fundamentals of SEO Marketing

To truly grasp SEO marketing, business owners and online marketers need to understand two fundamental concepts.

  • Organic Traffic vs Paid Traffic
  • Understanding the difference between SEO and SEM

Let’s dive into the details of both topics.

What is Organic Traffic?

Organic traffic refers to visitors who arrive at a website through search engine results, specifically Google. The advantage of organic traffic is that website owners do not have to pay a single baht for advertising to Google.

When people search for information on Google, they see a list of related websites beneath the ads, known as Organic Search. When users click on these websites, Organic Traffic is generated.

The amount of organic traffic is directly related to search rankings. The higher your website appears in search results, the more organic traffic you will receive.

One downside is that if you want to significantly increase your organic traffic, you need to dedicate 3-4 months to continuous SEO efforts to achieve your goals. This means that if you’re looking for an instant boost in website visitors, solely focusing on organic traffic may not be the best solution.

What is Paid Traffic?

Paid Traffic refers to website visitors who come from purchasing advertising space on search engines like Google. This may involve buying rankings on search results pages, which can appear higher than organic search results. Websites that pay for these placements typically display an “Ad” label next to their URL, indicating they have invested in search engine advertising.

The advantage of Paid Traffic is that it allows us to rapidly increase the number of visitors to our website. When we purchase ads, our site appears in prominent positions where people are most likely to see it, or even at the top of search results immediately.

However, the downside is that the increase in audience size will require a corresponding increase in advertising budget. Additionally, when we stop advertising, our website will drop in rankings or disappear from search pages.

In summary, Organic Traffic refers to website visitors who come without the need for paid advertising, while Paid Traffic consists of visitors generated through purchased ads on search engines.

SEO vs SEM

The next topic marketers need to understand is the difference between SEO and SEM, or Search Engine Marketing.

Why is it important to understand the differences between these two terms? SEO and SEM are not the same. Marketers or business owners need to choose the right approach that aligns with their goals and timelines.

SEO focuses on driving organic traffic through search engines, while SEM encompasses both organic and paid traffic strategies to enhance visibility in search results.

SEM includes advertising through Google Ads, such as advertising via Google Search Ads, Google Display Network (GDN), YouTube Ads, and Shopping Ads. This is a marketing strategy where website owners pay for ads to Google.

In summary, both SEM and SEO are strategies for marketing through search engines, but SEO specifically focuses on organic traffic, while SEM encompasses both organic and paid traffic.

SEO takes time. Can we solely focus on SEM through paid strategies?

One of the frequently asked questions is whether we can focus solely on SEM with paid traffic. Since SEO takes time to show results, many see paid advertising as a faster option.

The answer depends on individual perspectives, but Shifu suggests that marketers should implement SEO alongside SEM. Both strategies can work in tandem, allowing for adjustments in marketing practices that align with current goals.

For example, using Search Ads to promote a specific webpage can yield immediate results, such as for a product page or an event. In contrast, SEO is a long-term strategy focused on developing the website and content to consistently and sustainably increase organic traffic. Not only is this traffic free from advertising costs, but market research also confirms that organic search is perceived as more trustworthy by the general public, leading to higher click-through rates compared to Search Ads.

Benefits of SEO for Websites and Online Businesses

In addition to the importance of SEO mentioned above, SEO actually offers several other benefits for websites and brand businesses. Here’s a quick summary to help you see its significance even more clearly:

  1. Help businesses or brands build brand awareness, along with their products and services
  2. Continuously and sustainably increase website traffic
  3. Attract the right target audience that matches the products/services or content of the website through keyword selection
  4. Improve the desired outcomes such as sales, form submissions, and follower sign-ups, as the audience searching already has interest or need (Quality Traffic)
  5. Save on marketing and advertising budgets, as costs are significantly lower than other marketing strategies
  6. Establish credibility for the brand and enhance its expertise in its field
  7. Foster business growth and increased profitability through higher results and reduced expenses

Hiring an SEO expert vs doing it yourself: which is better?
