Title Tag

A title tag is the HTML element in a page's <head> that defines the page title, appearing as the clickable headline in search results.

Also called: SEO title tag, head title
Applies to: All web pages
Commonly confused with: H1 heading

Key points

Title tags help search engines and users understand page content and improve click-through rate.
Each page should have a unique, descriptive title tag around 50-60 characters.
Include the primary keyword near the beginning of the title tag.
Title tags are not the same as H1 headings, though they often match.
Search engines may rewrite title tags if they believe another version fits better.

How it works

A title tag is an HTML element placed in the page's <head> section. It is not visible in the body but appears as the blue clickable headline in search engine results pages (SERPs), in browser tabs, and in social previews. Search engines use the title tag as a primary signal to understand the page's topic and relevance to a user's query. For example, placing primary keywords near the beginning of the tag helps both users and algorithms quickly grasp the page's focus, such as in 'How to Bake Bread: A Beginner's Guide' where 'bake bread' is the primary keyword.

Best practice is to write a unique title tag for each page, keeping the length around 50-60 characters or roughly 550-600 pixels to reduce the chance of truncation. However, Google may rewrite titles if it thinks another version better matches the query or page context, so optimisation is a guideline rather than a guarantee. Monitor click-through rate (CTR) using Google Search Console when testing title changes.

The title tag also influences CTR. A compelling, intent-matching title can encourage searchers to click, which can improve organic performance. Because search engines may display a different title depending on the query, it is wise to write titles that are accurate and appealing across multiple potential queries.

Where it changes your decision

When optimising for click-through rate: a compelling title that matches search intent can significantly increase CTR, making it a key lever for traffic gains.
When targeting a specific primary keyword: placing it near the beginning of the title tag can improve relevance signals and help the page rank for that term.
When considering brand visibility: adding a brand name at the end of the title tag can aid recognition in SERPs and build trust over repeated impressions.

What it is not

Not the same as an H1 heading: the H1 is visible on the page itself; the title tag is in the <head> and appears in the SERP snippet along with the URL and meta description.
Not strictly limited to 60 characters: Google uses pixel width, so lengths vary. Use SERP preview tools to check truncation rather than relying solely on character count.
Not always displayed as written: search engines may rewrite title tags if they believe another version matches the query better or includes more relevant context.
Not a meta description: the meta description appears below the title in SERPs and does not directly affect rankings, but it can influence CTR by providing additional context.

Common mistakes

Using the same title tag across multiple pages: confuses search engines and users, reducing the likelihood of ranking for specific queries.
Making titles too long: causes truncation in search results, hiding key information like primary keywords or brand names, which reduces clicks.
Keyword stuffing: creates unnatural titles that hurt user experience and may be flagged as spam, leading to lower rankings or manual actions.
Ignoring search intent: writing accurate but unappealing titles can lower click-through rates even with good rankings, wasting potential traffic.
Failing to set a custom SEO title in content management systems: in WordPress, for example, the default title may not include primary keywords or a compelling call to action, so adjusting the SEO title WordPress field is essential.
