How search engines approach a page

Search engines don’t read pages like people do.

They:

  • Scan structure
  • Look for patterns
  • Use signals to infer meaning

Their goal is simple:

“What is this page about, and when should it appear?”

Your job is to make the answer obvious.

The main signals search engines look at

When interpreting a page, search engines pay close attention to:

  • The page title
  • The main heading (H1)
  • Subheadings (H2, H3)
  • The written content
  • Internal links pointing to and from the page
  • Image descriptions and context
  • The URL

No single element works alone.
Search engines look for consistency across all of them.

Consistency beats cleverness

A page performs best when:

  • The title, headings, and content all point to the same topic
  • Language is clear and specific
  • There’s no confusion about intent

Problems arise when:

  • A page tries to cover multiple unrelated topics
  • Headings don’t match the content beneath them
  • Titles promise something the page doesn’t deliver

Clarity always wins.

One page, one primary idea

A helpful way to think about on-page SEO is this:

If you had to describe the page in one sentence, could you?

If not, the page may be trying to do too much.

This doesn’t mean pages must be short — it means they must be focused.

Why structure matters so much

Structure helps search engines:

  • Identify the main topic
  • Understand subtopics
  • See how ideas relate to each other

It also helps humans:

  • Scan content
  • Find answers quickly
  • Stay engaged

Good structure is good SEO because it’s good communication.
