• Every indexable page needs one unique, descriptive title.
• Lead with the main topic and write for the person scanning results.
• Roughly 50 to 60 characters displays without truncation, but there is no penalty for longer.
• Google rewrites titles it considers inaccurate, repetitive or stuffed, so keep the title and H1 aligned.
• Test changes. Title edits can move click-through rate and rankings quickly.

The title tag sits in the head of a page and tells browsers, search engines and social platforms what the page is called. It shows in the browser tab, in bookmarks and, most of the time, as the blue link in search results.

Why it matters

• It is a direct, if modest, relevance signal.
• It heavily influences whether someone clicks your result.
• It is one of the cheapest things to change at scale.

How to write a good title

• Describe the page accurately. A title that overpromises earns a click and a quick return to the results.
• Put the important words first. People scan the left edge, and truncation happens on the right.
• Make each one unique. Duplicate titles make it harder for Google and users to tell pages apart.
• Match intent. A guide, a product page and a comparison each need a different shape of title.
• Add the brand at the end, usually after a separator. On the homepage it can lead.
• Write naturally. One clear phrase beats a list of keyword variations.

Length

Google has no character limit. Display space is measured in pixels, at around 600 pixels on desktop, which works out to about 50 to 60 characters. Longer titles are cut off with an ellipsis but the hidden words can still count for relevance. Aim to get the essentials inside the visible part and do not lose sleep over a few extra characters.

Templates for large sites

Hand-writing thousands of titles is not realistic, so build patterns from structured data:

• Product: [Product name] [key attribute] | [Brand]
• Category: [Category] [modifier such as "for women"] | [Brand]
• Location: [Service] in [Town] | [Brand]

Then hand-optimise the pages that carry the most traffic.

Why Google rewrites titles

Google generates its own title link when it thinks yours does not describe the page well. It draws on the title element, the main visible heading, og:title, other prominent text, and anchor text from links. Common triggers are:

• Titles that are very long or stuffed with keywords.
• Boilerplate repeated across many pages.
• Missing or half-empty titles such as "Home".
• A title that does not match the on-page heading.
• Out-of-date details such as last year in the title.

You cannot switch rewriting off. The best defence is a concise, accurate title that agrees with a single clear H1.

Common mistakes

• Missing titles, or more than one title element.
• The same title across paginated or filtered pages.
• Leading with the brand on every page.
• Writing for keywords and forgetting the human.
• Changing titles with JavaScript after load.
• All capitals, which is harder to read and takes more pixels.

How to test

• Crawl the site to find missing, duplicate, long and short titles.
• Use Search Console to find pages with high impressions and low click-through rate, which are good candidates for a rewrite.
• Search for your own pages to see whether Google is showing your title or its own.
• For large sites, run split tests on groups of similar pages and measure the change.

The GEO angle

When an AI system retrieves candidate pages, the title is one of the first things it uses to judge relevance, and it is often displayed as the label on a citation. Clear, literal titles that say exactly what the page answers do better here than clever or teasing ones.
