What is a title tag?

Title tag, explained

Every page should have one <title> in its head, and each should be different. Browsers show it in the tab, social previews often fall back to it, and search engines use it as the starting point for the result's headline, which Google calls the title link.

Google doesn't always use your title as written. Its documentation lists several sources it can draw from: the <title> element, the main visible title on the page, headings like <h1>, og:title, other large and prominent text, anchor text on the page, text in links pointing to the page, and WebSite structured data. It rewrites titles most often when they're missing, stuffed with keywords, the same across many pages, or don't match the page.

Google's advice is short: make each title descriptive and concise, avoid keyword stuffing, avoid repeated or boilerplate text, and make it clear which text on the page is the main title. There's no official character limit. Google says title links are truncated as needed to fit the device width. As a working rule, we keep titles to about 50–60 characters so the important words show on mobile, and put the most specific words first.

Brand names are optional. Google often shows your site name separately above the result, so adding "| Brand" to every title can waste space. On this site the brand suffix is only added when the full title still fits.

The title is also the single most useful thing to change on pages that already rank. On our own product, Versely, rewriting titles and snippets on pages sitting on pages one and two of Google produced the biggest wins of anything we did. The pages didn't change; the reason to click did.

Why it matters for founders

The title is what people read before deciding to click. On a page that already ranks, a better title can raise clicks without any new content or links, which makes it the cheapest SEO work there is.

Example

A tool page titled "Home | Acme Tools" becomes "Free AI crawler checker: is GPTBot blocked?". It now matches the query, reads well on mobile, and tells the searcher exactly what they'll get.

Common mistakes

• The same title on many pages, often the site name.
• Titles so long the key words are cut off on mobile.
• Keyword lists instead of a readable headline.
• A title that promises something the page doesn't deliver, which Google may rewrite.
