How do I add a meta tag to HTML source code?

Find clear answers to all your HTML meta tag questions


Interested in learning more about HTML (HyperText Markup Language) meta tags, the way they work, and how you can use them on your own website? Luckily, the team of technical SEO (Search Engine Optimisation) specialists at Aqueous Digital is here to help.

Below, we explore the definition of a HTML meta tag and the types of HTML meta tags.

We’ll also identify where you can find these tags, how they affect your SEO efforts, and how you can add a meta tag to your HTML source code – including how to insert a HTML custom meta tag.


What are meta tags in HTML?

HTML refers to a standardised system that uses code and meta tags to display content in a web browser. This HTML source code can determine the font style and size, colour, and graphics on a HTML page.

A meta tag in HTML is therefore a snippet of this code that provides additional data about data (metadata) and can be found in the HTML source code of a web page. These meta tags often provide further information about the HTML document, such as the title, description, author, publish date, file size, and location.


How do I find meta tags in HTML?

Metadata and meta tags are not displayed on a page. Instead, they can be found by right-clicking a web page and selecting ‘View page source’. This option displays the original, unformatted HTML or XML (Extensible Markup Language) source code as it was when delivered to the browser – complete with any meta tags.

While search engines read the HTML code of a page, online users focus on the on-page text and visuals. Meta tags, in some instances, can therefore be used for SEO and ranking purposes as well as helping online users find out more information about a page, but they don’t tend to affect online users in any other way.


How many meta tags in HTML?

There are many different meta tags for HTML pages, but (for indexing and crawling purposes) Google only supports a limited selection of meta tags and HTML attributes – 13 in total. Such meta tags include the adult content tag that identifies to Google whether the page contains adult content and therefore needs to be filtered by SafeSearch results.

Another example of a meta tag that Google supports is the mobile meta tag that shows the search engine how to render the page for mobile-users. Google typically uses these supported meta tags to create rich snippets and sort search results, ensuring users are provided with helpful and relevant results to the queries.

According to Google’s official advice, you can use up to 50 meta tags on each page. However, it suggests limiting this number to a more manageable figure. You can also add custom meta tags if you want to include information about the HTML page that doesn’t fit under any of the standard 13 meta tags that Google supports.


How to add a meta tag to your HTML source code

They way in which you can add meta tags to your website’s HTML source code will depend largely on the platform you used to create your website. For example, did you build your website using code from scratch or did you use a web content management system like WordPress, Wix, Magento, or another type of website builder?

Some platforms, like WordPress, will make editing your HTML source code more straightforward than directly editing the code itself. Plus, installing plugins on top of these platforms can make adding HTML meta tags even easier.

Typically, however, to insert a standard or custom meta tag you will need to edit the ‘<head>’ section of the HTML file. To do this, simply download the document, add the required meta tag using the relevant code and your preferred editor, then save and upload the HTML file to your site.
