Semantic HTML: Write a good meaning to SEO and Accessibility.

Beautiful website ... but why Google doesn't love? Problems hidden in the code you may overlook

Have you ever wondered ... Why our website is beautiful? The picture is clear. The content is packed. But when checking the rankings on Google, how almost couldn't find it? Or which is harder is Customers watch that the website is beautiful. But the team that had to continue to take care of the web complained that "Difficult to solve the code" and most importantly, some users Especially the visually impaired Almost can't use our website

This problem is like a mountain hair. We only focus on the "What it looking" until forgetting the most important foundation. The "structure and meaning" of the website are not caused by poor designs. But it is hidden in the HTML code that we use every day. And many people still make mistakes without knowing it

A picture of a website developer sitting in front of a computer screen that is full of complex HTML code. One side is a SEO graph that goes down to the other side, a user icon who is confused. Conveys a problem that is invisible but has a wide impact

The source of the problem: When we create a website with a "box" that is not named

Imagine that creating a website is like building a house. If we build a house using the "box" or "crate" that looks the same, it is all together as a bedroom, kitchen, bathroom, and then only use the paint or put the sign. Which box is? People who look from the outside may see that the house is beautiful. But if closing your eyes and trying to walk in this house How do you know where it is the door? Where is the window?

Writing a web with tags

The universal is no different. We use.,,,,Which says only Browser, "Here, show results like this", but for Googlebot or Screen Reader, it is just a "box" "box" and "box" that has no meaning at all. It doesn't know which part is the most important. Which part is the navigation menu Or which part is the main content of the page This is the source that makes both SEO and Web Accessibility. Ours broke without knowing it.

The comparison of 2 sides: the left side is the structure of the house that is built from a gray box as well. There is only a sign that "Bedroom", "Kitchen". The right side is the structure of each room that is clear, such as the kitchen with a counter. The bedroom has a bed. Convey the differences between non-semantic and semantic html

Let the "meaningless code" ... affect the business harder than expected

The use of non-semantic html, also known as "DIV SOUP" (Dive soup), is not just a technical matter that doesn't look promotion. But it directly affects the business in the main 3 dimensions

1. Begle is discounted (SEO FAILURE): When Google doesn't understand your web structure. It cannot assess which part of the content is the most important. Or this page has good or not? The result is that Google may prioritize your content wrong. Resulting in a good quality page to be ranked lower than it should be And losing a unfortunately business opportunity

2. Close the door at a large group of customers. (Accessibility Issues): visually impaired users have to rely on the Screen Reader program to "listen" on the website. If your website only has

The program will keep reading everything. No hierarchy Causing the user to be confused and finally left the website This is that you are rejecting this group of customers. And may be at risk of being sued about not supporting disabled people in some countries as well

3. Add the burden to the team (Maintenance Nightmare): Code is full.

Stacked into dozens of class, difficult to read, understand and solve in the future Allowing to improve or add new features to slow down and increase the cost of long -term maintenance unnecessarily

Powerful solution: Get to know "Semantic HTML"

The solution of this problem is easy and straightforward. That is to change to use ** Semantic HTML ** or "HTML meaning", which is the selection of HTML tags to "meet the meaning" of the content that is covered instead of using.

With everything, we changed to use a tag with a specific name instead.

Simply put, instead of building a house with "box". We come to build a house as well. "Brick" window "" Doors "with their own name and meaning.

Example of Semantic tag that should know and start using immediately:

• : For the head of the web or section, such as logo, main menu
• : For the main navigation links of the website (Navigation)
• : For the only "main" content of that page (not repeated)
• : For the content that ends in itself and can be published elsewhere, such as blog articles, 1 product
• : For organizing content that has the same topic such as section "our service", "about us"
• : For non -main part of the side, such as Sidebar, Advertising
• : For the end of the web or section, such as contact information, copyright

• and: For pictures and pictures lectures

The beginning is very easy. Just change the view from thinking that "What will the website look like?" "** What is our content structure? **" And choose the correct tag for use. You can study more about each tag, detailed from a reliable information source like MDN Web Docs .
