A title tag is the HTML element that names a web page. It sits in the page's code, shows up in the browser tab, and is the main source Google uses for the clickable headline in search results. It is one of the smallest pieces of a page, and one of the most visible.
What is a title tag?
A title tag is the <title> element inside a page's <head> section. People see it in browser tabs, bookmarks, shared links, and on the SERP (search engine results page).
Google calls the headline it shows in results a "title link." The two are related but not identical. According to Google's title link documentation, the title link is generated automatically from several sources, including the <title> element, the main visible heading, other <h1> and heading elements, og:title tags, anchor text in links pointing to the page, and WebSite structured data. Your title tag is a key input, but Google can choose something else.
Why title tags matter
The title link is usually the first thing a searcher reads about your page. A clear, specific title helps the right people recognize that your page answers their question. A vague one ("Home" or "Services") gets skipped, even when the page ranks well.
Titles also help search engines understand the topic of a page. Google's SEO Starter Guide describes a good title as unique to the page, clear and concise, and accurate about the page's contents.
How Google decides what title to show
Google rewrites title links when it thinks the title tag doesn't describe the page well. Its documentation lists the common triggers:
- Half-empty titles: part of the title is missing, such as a title that is only the site name.
- Obsolete titles: an old year in the title while the page heading shows a newer one.
- Inaccurate titles: the title doesn't match what the page actually covers.
- Micro-boilerplate: many pages share nearly the same title, so Google can't tell them apart.
- No clear main title: several headings look equally prominent.
Google also notes there is no hard character limit for the title element. Title links are truncated to fit the device's width, which is why putting the important words first matters more than hitting an exact count.
How to write a good title tag
- Give every page its own title. Duplicate or templated titles make pages hard to tell apart. Templates for product or location pages should include the detail that makes each unique.
- Lead with the topic. Put the main subject, usually your primary keyword, near the start. Long titles get cut off, and the beginning is what people scan.
- Keep it concise. Google gives no exact limit, but Semrush suggests about 550 pixels, typically 50 to 60 characters, so the full title fits on most screens. Treat that as a guideline, not a rule.
- Match search intent. Think about what the searcher wants. A "how to" guide, a pricing page, and a product comparison each deserve different wording. Our page on keyword intent covers this in more depth.
- Brand it lightly. Google suggests adding your site name at the start or end, separated by a hyphen, colon, or pipe. Save fuller branding for the homepage.
- Align the title and the H1. They don't need to be identical, but they should describe the same thing. Mismatches are one of the main reasons Google rewrites titles.
- Keep dates current. If a title includes a year, update it when the content is updated, or remove the year.
A simple example: a local bakery's catering page titled "Services" tells nobody anything. "Wedding and Event Catering in Austin | Rise Bakery" names the offer, the location, and the brand in about 50 characters. (The bakery is hypothetical.)
Common title tag mistakes
- Keyword stuffing. Repeating the same phrase ("Cheap Shoes, Cheap Running Shoes, Cheap Shoes Online") looks spammy, and Google specifically warns against it.
- Clickbait. A title that overpromises may earn a click, but a quick bounce back to results helps no one, and an inaccurate title is more likely to be rewritten.
- Forgetting the tag entirely. Some CMS setups leave titles blank or default to the site name on every page. Audit for this regularly.
How Butter approaches title tags
At Butter, title tags are part of the routine on-page work, not a one-time fix. We review titles alongside the meta description and headings, check for duplicates and outdated years, and rewrite titles that don't match what a page actually delivers. We also look at how Google is currently displaying a page's title in results, since a rewritten title link is often a signal that the page and its title have drifted apart.
On our GEO+SEO plan, title updates fall under unlimited on-page optimization. On the GEO plan, they come as part of our monthly on-page recommendations.
Frequently asked questions
How long should a title tag be?
Google says there is no hard limit and that title links are truncated to fit the device width. Industry guides such as Semrush suggest roughly 50 to 60 characters so the full title shows on most screens. Put the most important words first either way.
Why does Google show a different title than the one I wrote?
Google generates title links automatically and may rewrite a title that is missing, outdated, inaccurate, or nearly identical to others on your site. Make sure your title and main heading describe the same thing. If none of the known issues apply, Google may simply think its version fits the query better.
Should every page have a unique title tag?
Yes. Google recommends a unique, specific title for every page. Duplicate titles make it hard for search engines and searchers to tell pages apart.
