Best Practices for Implementing Heading Tags
Heading tags are a cornerstone of web page structure, but what exactly is a heading tag in a website? Simply put, a heading tag is an important HTML element that creates a hierarchical level of content organization, to help search engines understand web page content relationships. It also helps to improve accessibility for screen readers and assists users to quickly scan and process information.
HTML Heading Tag Structure
There are six heading tags, written and ordered as: <h1></h1>, <h2></h2>, <h3></h3>, <h4></h4>, <h5></h5> and <h6></h6>. The H1 heading tag represents the most important heading topic, while the H6 heading tag represents the least important. The structure is set up as an opening and closing heading tag with the actual “heading” in between the two…for example, <h1>What are Tags in a Blog Post?</h1>.
Typically, your H1 heading tag is used for a web page’s main title while H2 through H6 are used for subheadings. It is generally recommended that you only have one H1 tag per web page. And heading tags should follow a logical, descending hierarchy from H1 (near the top) to H2, H3, H4, H5 and H6 as you go further down the page. Jumping around with heading tags, say from H1 to H4 then to H2 as you move down a web page can confuse Google and your website visitors using screen readers.
For example, a recipe on a food blog could have its heading tag structure set up like this: <h1>Simple Fish Taco Recipe</h1> followed by <h2>Ingredients List”</h2> followed by <h3>Marinades</h3>.
SEO Implications of Heading Tags
You can make it easier for search engines like Google to understand your web page content when using best practices to implement heading tags. That is because heading tags inform search engines about the hierarchal importance of and relationships between different sections of web page content.
Semantic Significance for Search Crawlers
Heading tags act as signposts for search engine bots (and humans). An H1 with your key phrase tells the bot, “This page covers [topic].” H2 heading tags outline key parts, and H3 heading tags dive deeper.
Some studies have shown that web pages with proper heading structures often rank better for queries. Avoid keyword stuffing and instead keep it natural and informative.
Enhancing Snippets and Rich Results
Well-structured and clearly written web page headings can increase your eligibility for placement in Google’s featured snippets—those quick answers at the top of search results. Clear H2 and H3 heading tags make it easy for the algorithm to grab and display your content. They also feed into “People Also Ask” sections of Google SERPs. Users click those expandable boxes often. If your web page headings match search intent, you can gain visibility in site links as well.
User Experience (UX) and Readability Advantages
Most people do not read web pages word-for-word. They tend to skim or scan to more efficiently find information. To that end, headings (the text titles and subtitles inside heading tags) guide readers’ eyes to aid it getting a quick understanding of what the web page is generally about.
Improving Content Scannability and Engagement
Headings are also used to break up the flow, using bold or larger text and space to draw attention. This can boost user engagement—a key metric for success.

As mentioned earlier in this article, it is recommended that you stick to using just one H1 per page for accessibility and less semantic ambiguity for users. Usually, the H1 heading matches or closely aligns with the page title.
