We checked the H1 headings of 30 UK small business websites — the first and most prominent heading on each homepage. More than half either had no H1 at all, or had one that did not clearly describe what the business does.


TL;DR

  • 15 out of 30 UK SME websites (50%) had no detectable H1 heading on their homepage
  • Of the 15 that had an H1, only 14 clearly stated the business type or service offered (47% overall)

Why the H1 matters

The H1 tag is the primary heading of a web page. In HTML, it is meant to describe what the page is about. On a homepage, it typically serves as the first statement a visitor — or a machine — encounters.

For human visitors, the H1 is read in context. A visitor who arrives at a plumber's website already knows they're looking at a plumber, so a heading like "London's No.1" makes sense alongside the imagery, navigation and surrounding content.

For AI systems crawling the page, context is less certain. The H1 is one of the earliest text signals processed, and it carries weight in determining what the page — and by extension the business — is about. An H1 that says "Online Personal Trainer for Busy Professionals" gives a clear signal. An H1 that says "YOUR SUCCESS STARTS HERE" gives none.

This does not mean AI systems rely solely on the H1. They process the entire page. But in a world where AI platforms are parsing millions of business websites, a clear first signal r
