What is HTML?

The markup language used to structure webpage content.

In plain English

HTML is the structure of a page. It says this is a heading, this is a paragraph, this is a link, this is an image. It does not decide how those things look, only what they are.

That distinction matters for marketing. Search engines and screen readers read the structure, not the styling. A heading that looks like a heading but is marked up as a paragraph tells them nothing.

What to know

Elements and tags
Content sits inside tags that describe it. Headings from H1 to H6, paragraphs, lists, links, images, tables. Each tag carries meaning.
Semantics over appearance
Use the element that matches the meaning. A list should be a list, a heading should be a heading. Styling can make anything look like anything, but only markup carries meaning.
One H1, a logical order
A page has one main heading and subheadings in sensible order. This is how both crawlers and screen readers build a picture of the page.
Where SEO lives
Title tags, meta descriptions, heading structure, alt text, canonical tags and structured data are all HTML. Most on-page SEO is markup work.

Why it matters

You do not need to write HTML to run marketing, but you need to know it exists and what it controls. Almost every technical SEO recommendation, accessibility fix and page-speed improvement comes down to what is in the markup. Understanding that keeps you from being at the mercy of whoever does.

Common mistakes

×Using headings for visual size rather than document structure.
×Styling text to look like a heading without marking it up as one.
×Leaving alt text empty on images that carry meaning.
×Assuming a page builder produces clean markup by default.

FAQs

Do I need to learn HTML to do marketing?

Not to write it from scratch, but a working understanding pays for itself. Recognising a heading structure or an alt attribute lets you brief and check work properly.

Does HTML affect SEO?

Yes, heavily. Titles, headings, links, alt text, canonicals and structured data all live in HTML. It is where most on-page SEO is implemented.
