H1 Tag
Quick Definition
The H1 tag is the main heading of a web page defined in HTML. Each page should have exactly one H1 that includes the primary keyword and clearly describes the page's topic for both users and search engines.
Why It Matters
The H1 tag is the main heading of a webpage and one of the strongest on-page SEO signals. It tells both users and search engines what the page is about. According to a study by Ahrefs, 85% of top-ranking pages have an H1 tag that closely matches the page title tag (Ahrefs, 2024).
Real-World Example
For a page targeting best laptops under 50000 in India, the H1 should be something like Best Laptops Under Rs 50,000 in India (2026 Updated). This includes the primary keyword naturally while adding value signals like the year and price in local currency.
Signal Connection
Relevance -- the H1 tag is a primary relevance signal. It tells Google exactly what the page is about. A well-crafted H1 that matches search intent strongly influences how Google categorizes and ranks the page.
Pro Tip
Use only one H1 per page (although HTML5 technically allows multiple). Make it descriptive, include your primary keyword naturally, and ensure it accurately represents the page content. The H1 does not need to exactly match the title tag but should be closely related.
Common Mistake
Using the company logo as the H1 tag on every page, or using the same H1 across multiple pages. Each page should have a unique, descriptive H1 that reflects its specific content and target keyword.
