Title Tag

The title tag is the HTML element that defines the title of a web page, placed within the <head> section of the source code. Displayed as the clickable headline in Google search results and in the browser tab, it is one of the most important on-page signals for organic search. The title tag tells search engines and users the main topic of the page. It has a direct effect on click-through rate from the SERP: a clear title that contains the target keyword and stays under roughly 60 characters maximises visibility without being truncated. Every page should have a unique, descriptive title tag. In 2026, AI search engines also rely on this signal to identify and summarise a page's content, which reinforces its importance for citability in generative answers.

The title tag is the first signal a search engine and a user perceive about a page. It appears as the clickable blue headline in Google results, in the browser tab and when pages are shared on social media. When well optimised, it directly increases click-through rate and supports rankings.

How it works

The title tag is declared in the HTML <head>: <title>Your title here</title>. Crawlers such as Googlebot read it during the crawl to understand the topic of the page, then use it as the main headline in the SERP. It differs from the H1 tag, which structures the visible content: the title tag lives in the code and the search results, while the H1 lives on the page.

To be effective, a title tag must be unique across the whole site, contain the main keyword at the start of the string, stay under ~60 characters and entice the click. Adding the brand name at the end of the title strengthens recognition without hurting readability.

A concrete example

Compare two titles for a page about content optimisation:

Weak: "Home - Page 3 - My Site"
Optimised: "SEO Content Optimisation: Complete 2026 Guide | LUWIZ"

The second clearly states the topic, places the keyword first and signals freshness. The result: a better click-through rate and a stronger relevance signal.

A retenir

A unique, descriptive title tag under 60 characters, with the keyword at the start of the string, is the most cost-effective on-page lever for winning clicks.

Why it matters

The title tag influences both ranking and user behaviour. In 2026, AI search engines also rely on this title to identify and summarise a page in their answers. A precise title therefore improves citability in generative results. That is why we systematically audit it in our SEO engagements.

Aim for 50 to 60 characters. Beyond roughly 600 pixels, Google truncates the title in results. Place the important keyword at the start of the tag so it stays visible even if the title is cut off.

Yes. Google may replace your title with another snippet it deems more relevant to the query, often pulled from the H1 or the content. A clear, unique title aligned with search intent sharply reduces the risk of rewriting.
