Meta tags that Google understands
Google supports both page-level meta-tags and inline directives to help control how your site's pages will appear in Google Search.
Page-level meta tags are a great way for website owners to provide search engines with
information about their sites. Meta tags can be used to provide information to all sorts of
clients, and each system processes only the meta tags they understand and ignores the rest.
Meta tags are added to the
<head> section of your HTML page and generally
look like this:
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <meta name="description" content="Author: A.N. Author, Illustrator: P. Picture, Category: Books, Price: £9.24, Length: 784 pages" /> <meta name="google-site-verification" content="+nxGUDJ4QpAZ5l9Bsjdi102tLVC21AIh5d1Nl23908vVuFHs34=" /> <title>Example Books - high-quality used books for children</title> <meta name="robots" content="noindex,nofollow" /> </head> </html>
Google understands the following meta tags:
|Meta tags that Google understands|
||Use this tag to provide a short description of the page. In some situations, this description is used in the snippet shown in search results.|
These meta tags control the behavior of search engine crawling and indexing.

You can also specify this information in the header of your pages using the "X-Robots-Tag" HTTP header directive. This is particularly useful if you wish to limit indexing of non-HTML files like graphics or other kinds of documents. More information about robots meta tags.
||When users search for your site, Google Search results sometimes display a search box specific to your site, along with other direct links to your site. This tag tells Google not to show the sitelinks search box. Learn more about sitelinks search box.|
||When Google recognizes that the contents of a page aren't in the language that the user likely wants to read, Google may provide a translated title link and snippet in search results. If the user clicks the translated title link, all further user interaction with the page is through Google Translate, which will automatically translate any links followed. In general, this gives you the chance to provide your unique and compelling content to a much larger group of users. However, there may be situations where this is not desired. This meta tag tells Google that you don't want us to provide a translation for this page.|
||Prevents various Google text-to-speech services from reading aloud web pages using text-to-speech (TTS).|
||You can use this tag on the top-level page of your site to verify ownership for
Search Console. Please note that while the values of the
||This defines the page's content type and character set. Make sure that you surround the value of the content attribute with quotes - otherwise the charset attribute may be interpreted incorrectly. We recommend using Unicode/UTF-8 where possible. More information.|
||This tag sends the user to a new URL after a certain amount of time, and is sometimes used as a simple form of redirection. However, it is not supported by all browsers and can be confusing to the user. The W3C recommends that this tag not be used. We recommend using a server-side 301 redirect instead.|

Other points to note
- Google can read both HTML and XHTML-style meta tags, regardless of the code used on the page.
- With the exception of
google-site-verification, letter case is generally not important in meta tags.
- This is not an exclusive list of meta tags. You can use other meta tags if they are important to your site, but Google will ignore meta tags that it doesn't know.
Independently of page-level meta-tags, you can exclude parts of an HTML page from snippets.
You can do this by adding the
data-nosnippet HTML attribute to one of the
supported HTML tags:
<p> This text can be included in a snippet <span data-nosnippet>and this part would not be shown</span>. </p>
To ensure machine readability, the section must be valid HTML and all tags closed accordingly.
