Hreflang is a term used in the context of search engine optimization (SEO) to describe the use of the hreflang attribute in HTML. The hreflang attribute is used to indicate the language and geographical targeting of a webpage, and it helps search engines understand which version of a page to show to a user based on their location and language preferences.
The hreflang attribute can be added to the <head> section of an HTML page, and it takes the form of a <link> element with the rel attribute set to "alternate" and the hreflang attribute set to a language and region code. For example, a page targeted at users in the United States who speak English might have the following hreflang attribute:
<link rel="alternate" hreflang="en-US" href="https://example.com/page" />
In this example, the hreflang attribute indicates that the page is written in English (en) and is targeted at users in the United States (US). This information can be used by search engines to show the correct version of the page to users based on their location and language preferences.
Overall, the hreflang attribute is an important tool for improving the visibility and relevance of a website in search results. By indicating the language and geographical targeting of a page, the hreflang attribute can help search engines show the correct version of a page to users, and provide a better user experience.
