How Google chooses the title shown in search results

What is a title link?

A title link is the prominent, clickable text that appears as the title of a search result on Google Search. This link directs users to the specific web page it represents. Title links are also used on other Google properties, such as Google News.

How does Google generate title links?

Google's process for generating title links on its search results page is entirely automated. This system takes into account both the content present on a web page and any references to that page found elsewhere on the web.

Google Search uses several sources to automatically determine the most appropriate title link. These sources include the content within the HTML <title> element, the main visual title displayed on the page, and heading elements like <h1>. Other content that is large and prominent due to style treatments, as well as other text contained within the page, can also be considered. Additionally, Google looks at anchor text on the page, text within links that point to the page, and WebSite structured data. If an issue is detected on a page, Google may attempt to generate an improved title link from these various sources.

Why is the HTML <title> element important?

The HTML <title> element defines the document's title, which is typically shown in a browser's title bar or a page's tab. According to W3C, every HTML document must include a <title> element within its <head> section. The <head> section contains information about the document, such as its title, rather than the document's actual content.

The content of a page's title has significant implications for search engine optimization (SEO). Search engine algorithms use the title as one of the components to decide the order in which to list pages in search results. Authors should use the <title> element to clearly identify the document's contents and provide context-rich titles, especially since users often encounter documents out of their original context.

Google recommends ensuring every page on a site has a specified <title> element and that the text is descriptive and concise. Search engines typically display about the first 55 to 60 characters of a page title. If a longer title is necessary, important information should appear earlier in the title. It is also beneficial to make titles as unique as possible across a website, ideally surfacing the primary purpose of the page first, followed by the website's name. Titles can contain character entities for special characters but should not include other markup.

How do Open Graph tags influence titles?

The Open Graph protocol allows any web page to become a rich object within a social graph. To achieve this, basic metadata is added to the page, typically as <meta> tags placed in the <head> section of the web page. If a web page is not explicitly marked up, it is treated as an `og:type website` by default.

One specific Open Graph tag, `og:title`, defines the title of an object as it should appear within the graph. Google considers content in `og:title` meta tags as one of the sources when automatically determining title links for search results. If a tag can have multiple values, such as multiple `og:title` tags, the first tag encountered from top to bottom on the page is given preference during conflicts.

How do site names differ from title links?

When Google lists a page in search results, it displays the name of the site the page originates from. This site name is distinct from the per-page title links. Title links are specific to each individual web page, whereas the site name applies to the entire website.

Google's generation of site names on the search results page is also fully automated. This process considers content from a site's home page and references to the site found across the web. To indicate a preferred site name, Google recommends adding WebSite structured data to the home page. While other sources like `og:site_name`, <title> elements, and heading elements on a home page are considered, WebSite structured data is the most important method for specifying a preference.

If the automated system does not select the preferred site name, it is important to verify that the site name in the WebSite structured data on the home page matches the desired name. If updates are made to the site name structured data, time must be allowed for Google to recrawl and process the new information.

How long does it take for title link changes to appear?

When updates are made to the sources Google uses for title links, such as the <title> element or other on-page content, Google must recrawl and reprocess the page to notice these changes. This process can take a few days to a few weeks before the updates are reflected in search results. Similarly, if site name structured data is updated, time is needed for Google to recrawl and process the new information.
