What Is a Markup Language?

A markup language is a algorithm that defines how the format and presentation of textual content and pictures ought to seem in a digital doc. It permits structuring paperwork, including formatting, and specifying how completely different parts must be displayed (or “rendered”) on webpages.

This structuring helps serps like Google perceive the knowledge on web sites higher. If serps know extra about what a web page is about, they’re extra more likely to present it to people who find themselves searching for its content material. Which, in end result, can carry extra individuals to web sites with the fitting markup.

An instance of a markup language—and the one most individuals know—is HTML. And it appears like this:

On a webpage, that’ll appear to be this:

Another markup language examples embody:

However we’ll get into these later.

For now, observe that markup languages are completely different from programming languages.

Programming languages are used to create practical and dynamic net purposes.

Markup languages focus totally on the presentation and construction of content material. They’re static and don’t use logic or algorithms.

To offer you a good higher thought of what markup languages are, let’s look nearer at two classes of markup languages: semantic and presentational markup.

Semantic Markup

Semantic markup, also called semantic HTML, defines sections of a webpage to assist browsers, serps, and builders higher perceive the content material of that webpage.

Right here’s a easy illustration to indicate you what meaning:

An illustration of what a semantic HTML is

Whereas the non-semantic <div> and <span> tags work for formatting, semantic tags like <article>, <part>, and <nav> outline every factor in your webpage.

In different phrases, semantic markup provides a layer of data that makes it simpler for serps and different related events to grasp your content material.

Professional tip: Already utilizing semantic markup however nonetheless don’t see search engine marketing outcomes? Perhaps there’s an issue. Discover out with Semrush’s Web site Audit device:

Presentational Markup

Presentational markup focuses on the content material’s look, together with font dimension, coloration, alignment, and different visible kinds.

With HTML, presentational markup was generally utilized in earlier variations to outline the format and design of webpages instantly throughout the code.

Tags like <b> for daring textual content, <i> for italicized textual content, and <font> to specify font properties are good examples of presentational markup.

These days, presentational markup is usually discouraged in favor of separating content material and presentation. Separating content material and presentation permits for higher group. It makes it simpler to replace the design with out affecting the knowledge. And vice versa. 

3 Advantages of Utilizing Markup Languages

Utilizing markup languages in your web site has many benefits. Listed here are three to bear in mind:

1. They Enhance search engine marketing

Tags inform browsers extra in regards to the content material in your web page.

See tags as landmarks on a map. They pinpoint essential spots, serving to serps navigate and comprehend your content material’s construction and that means. 

Right here’s a technique that works.

Once you skim a ebook or web site, you have a look at the names and subtitles to determine what the primary level is.

Equally, serps use heading tags—just like the <h1>, <h2>, and <h3>—as signposts. These headings make content material simply digestible for readers. And inform serps in regards to the hierarchy of your info.

After which there’s semantic markup. Utilizing semantic markup tags is your means of talking the major search engines’ language. And including a layer of data and context to your paperwork. 

Take the <foremost> tag, for instance. It specifies a doc’s major content material. All the things throughout the <foremost> factor must be distinctive to that doc, omitting recurrent content material equivalent to sidebars or navigation hyperlinks.

After which, we have got the <apart> tag. This tag is used for content material that’s associated however distinct from the primary content material. Search engines like google acknowledge it as supplementary materials. Typically, web site sidebars are contained throughout the <apart> tag.

2. They Create Constant Layouts

Markup languages function a uniting pressure, permitting for constant layouts throughout a number of platforms.


They outline the construction and content material of a doc in a universally understood means. This methodology ensures that your content material seems the identical to everybody, whatever the know-how they’re utilizing.

Webpage layout in different formats, including iPhone 13, tablet and laptop/desktop

This uniform rendering goes past improved aesthetics; it gives a user-friendly expertise and seamless navigation. 

Markup language allowed builders to create templates—predefined buildings with placeholder content material. Customers might then substitute these placeholders with their content material by merely filling within the blanks.

3. They Improve Accessibility

Internet accessibility allows individuals with disabilities to entry and work together together with your web site. Markup languages excel on this space as a result of they use semantic tags so as to add that means on prime of the content material construction.

Markup languages could be interpreted by assistive applied sciences equivalent to display readers, bridging the hole between content material and people who have to entry it otherwise.

Making web sites extra accessible helps be certain that your digital world is welcoming. Correct markup not solely helps you adhere to some authorized and moral pointers associated to accessibility but in addition embodies a dedication to reaching each potential consumer.

How Markup Languages Work

Understanding the workings of markup languages is much less advanced than it could initially sound.

Tags and Parts

A markup tag tells browsers the way it ought to show content material. Or defines what that piece of content material is.

For instance, that is what an HTML tag appears like.


That tag signifies that the content material must be bolded.

Tags are normally enclosed in opening and shutting brackets. And are available in pairs—a gap tag and a closing tag.

This is what that appears like:


A component consists of the tag and the content material that the tag defines.

For instance, this is a component:

<b>This is an factor</b>

And here is what that can appear to be on a webpage:

"<b>This is an element</b>" on a webpage

When a program, like an internet browser, encounters a doc with markup tags, it interprets them as cues for presenting the content material.

As an illustration, in HTML, tags equivalent to <h1> to <h6> and <p> outline headings and paragraphs, respectively. 

These tags inform browsers two issues:

  • How the textual content ought to seem: <h1> is often greater and extra emphasised than <h6>. Which is extra emphasised than <p>.
  • The construction of the content material: The <h1> tag represents the primary idea or thought of a web page. Whereas you should utilize <h2> to <h6> tags to construction your content material into subtopics.


HTML parts embody attributes. Attributes are additional values used to set a component’s traits or modify its habits in numerous methods to satisfy your necessities. 

Take a well-liked HTML tag like <a>. We use it to create hyperlinks and might add a number of attributes to customise its habits.

A primary instance of a hyperlink to Semrush’s homepage would appear to be this:

A basic example of a link to Semrush’s homepage

As an instance you wish to pressure the hyperlink to open in a brand new tab. 

Merely add one other attribute—”goal”—to specify your instruction.

A basic example of a link to Semrush’s homepage with target specified

Now, when somebody clicks on that hyperlink, it’ll open in a brand new tab.

HTML, XML, SGML, and XHTML are the most typical among the many numerous markup languages accessible.

HTML: The Internet Spine

HyperText Markup Language (HTML) is the most well-liked markup language. Internet builders use it to construction content material on the net, together with headings, paragraphs, pictures, hyperlinks, and extra.

HTML additionally gives the foundational construction upon which all the things else is constructed. Whereas HTML lays out the content material, extra languages like Cascading Model Sheets (CSS) and JavaScript (JS) can be utilized on prime to shine the looks and dictate how parts work together.

For instance, you would simply use XML to explain a recipe. Right here’s one instance for a fruit salad recipe.

A fruit salad recipe described in XML

Right here’s a breakdown of what this code means:

<?xml model=”1.0″ encoding=”UTF-8″?>: That is the XML declaration. It defines the XML model and the character encoding used within the doc.

<!DOCTYPE … >: That is the Doc Kind Definition (DTD). It defines the construction and the authorized parts and attributes of the XML doc. On this case, it specifies the construction and parts that can be utilized in our recipe.

  • <recipe> accommodates your complete fruit salad recipe.

XML sitemap example

Search engines like google can use this knowledge to find out how usually to crawl every web page and its relative significance in comparison with different web site pages.

It’s value noting that Google ignores the <changefreq> and <precedence> tags.

The <lastmod> tag can be utilized, however provided that it may be relied upon to be right (for instance, if the dates in your sitemap do not appear to match up, Google could cease trusting it).

Professional tip: Create your XML sitemap and submit it through Google Search Console. It would assist Google uncover and index your content material web site quicker.

SGML: The Precursor to HTML and XML

SGML is a framework for creating personalized markup languages tailor-made to particular wants.

To begin with SGML, you first craft a Doc Kind Definition (DTD). The DTD outlines the construction, units the boundaries, and lists the weather, attributes, and entities you should utilize in your doc.

To create an e mail in SGML, it’s possible you’ll, as an example, write the next code:

An example of a code for creating an email in SGML

It’s possible you’ll now write your doc based on the established pointers, marking up the textual content with the elements and traits you have set.

An example of an email in SGML

That being mentioned, SGML is now much less related.

HTML and XML are extra user-friendly and broadly supported. So most builders favor these languages over SGML.

XHTML: Bridging HTML and XML with Strict Requirements

XHTML is a hybrid between HTML and XML, basically combining the presentation capabilities of HTML with the strict syntax guidelines of XML. 

As step one towards a extra organized and constant net, XHTML was developed to enhance code and browser compatibility. 

The delivery of HTML5 modified issues. HTML5 addresses lots of XHTML’s advantages and provides cutting-edge net options. Most builders now use HTML5 over XHTML resulting from its adaptability and talent to maintain up with the continuously evolving digital panorama, 

One of many vital benefits of XHTML is its adherence to XML guidelines, which helps guarantee consistency within the markup. 

Bonus: Honorable Mentions

Past the headliners, there is a backstage stuffed with lesser-known but compelling languages that deserve point out.

  • Scalable Vector Graphics (SVG): Permits pictures to be resized with out dropping high quality, excellent for crisp graphics on the net
  • TeX: Used for making math and technical papers look neat {and professional}
