Headings are among the most basic building blocks of a web page, yet they have long been the subject of debate in the SEO community. In 2019, marketers were asking how important H1 tags were for SEO, whether a page could have more than one, and whether Google even cared. The H1 tag is typically the main heading on a page, and it signals the primary topic to both users and search engines. While it was never the single most powerful ranking factor, it played an important supporting role in on-page optimization, accessibility, and user experience.

What Is an H1 Tag?
HTML provides six levels of headings, from h1 to h6. The H1 is the top-level heading and usually represents the main title of the page content. On a blog post, it is typically the article title. On a product page, it is the product name. On a service page, it describes the service. Subheadings use H2, H3, and so on to organize content into sections and subsections.
What Google Said About H1 Tags in 2019
In 2019, Google's John Mueller addressed H1 tags several times. He explained that Google uses headings to better understand the content and structure of a page, and that headings help Google identify what a page is about. However, he also stated that a page could have multiple H1 tags without being penalized, and that Google's systems are capable of handling pages with no H1 or several H1s. HTML5 had already made multiple H1s technically valid within different sectioning elements, so Google adapted accordingly.
The key message was that H1 tags are a helpful signal, not a strict requirement. Pages would not fail to rank simply because their heading structure was imperfect, but clear headings made it easier for Google to interpret content correctly.
Why H1 Tags Mattered for SEO
Even without being a heavy ranking factor, H1 tags offered several SEO benefits in 2019:
- Topical clarity: A descriptive H1 containing the primary keyword reinforced the page's main subject.
- Content hierarchy: Proper heading structure helped search engines understand how sections related to each other.
- Featured snippets: Clear headings increased the chances of content being pulled into featured snippets, which were extremely prominent in 2019.
- User experience: Visitors could immediately confirm they had landed on the right page, reducing bounce rates.
- Accessibility: Screen readers use headings for navigation, making well-structured pages more usable.
H1 Tags vs Title Tags
A common confusion in 2019 was the difference between H1 tags and title tags. The title tag appears in browser tabs and search results, while the H1 appears on the page itself. Both should reflect the page's topic, but they do not need to be identical. The title tag is often optimized for click-through rate with brand names or compelling modifiers, while the H1 can be slightly more descriptive or conversational. Aligning them helps reinforce relevance without unnecessary repetition.
Best Practices for H1 Tags
The H1 best practices recommended in 2019 remain sound today:
- Use one clear, descriptive H1 per page as a best practice for clarity, even though multiple H1s are technically allowed.
- Include the primary keyword naturally, ideally near the beginning.
- Keep it concise, generally under 70 characters.
- Make it unique across your website to avoid confusion between pages.
- Ensure it accurately describes the content that follows.
- Do not hide the H1 or style it to be invisible, as that can appear manipulative.
Common H1 Mistakes in 2019
Many websites made avoidable mistakes with H1 tags. Some themes wrapped the site logo in an H1 on every page, resulting in identical H1s sitewide. Others used H1 tags purely for styling large text, leading to multiple unrelated H1s on a single page. Some pages had no H1 at all because the main title was styled with a div or span. Keyword stuffing in H1s, such as repeating a phrase several times, was another issue that hurt readability without helping rankings.
The Role of Subheadings
H1 tags work best when supported by a logical hierarchy of H2 and H3 headings. In 2019, long-form content was widely favored, and subheadings made lengthy articles skimmable. Using related keywords and questions in H2s helped capture additional long-tail traffic and People Also Ask placements. A clear hierarchy also helped Google's natural language systems, including BERT, which began rolling out in late 2019, understand the context of each section.
How H1 Importance Has Evolved Since 2019
Since 2019, search engines have become even better at understanding content without relying heavily on HTML signals. However, headings remain useful. Google still uses headings as context clues, and AI-driven search features often extract information from well-structured sections. Clear H1s and logical subheadings are also beneficial for generative search engines that summarize content. The fundamentals established in 2019 continue to serve websites well.
How to Audit Your H1 Tags
Use crawling tools such as Screaming Frog or Sitebulb to identify pages with missing, duplicate, or multiple H1 tags. Review templates in your CMS to ensure logos and navigation elements are not using H1 tags. Prioritize fixes on high-value pages first, such as service pages, product categories, and popular blog posts.
Conclusion
In 2019, H1 tags were important for SEO not because they were a dominant ranking factor, but because they helped search engines and users understand the main topic of a page. Google confirmed that multiple or missing H1s would not lead to penalties, yet clear, descriptive headings remained a best practice. Combined with a logical heading hierarchy and quality content, well-crafted H1 tags continue to support rankings, accessibility, and user experience.
