Google supports both page-level meta-tags as well as inline directives to help control how your site's pages will appear in Search.
Page-level meta tags are a great way for webmasters 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">
Google understands the following meta tags (this list is not exhaustive):
||Use this tag to provide a short description of the page. In some situations this description is used as a part of the snippet shown in the search results. More information|
These meta tags control the behavior of search engine crawling and indexing.
In the case of conflicting
The default values are
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 are not in the language that the user is likely to want to read, Google often provides a link to a translation in the search results. 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 web browsers from reading aloud the tagged page using the Google Assistant voice commands "Read this page" and "Read it."|
||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 "name" and "content" attributes must match exactly what is provided to you (including upper and lower case), it doesn't matter if you change the tag from XHTML to HTML or if the format of the tag matches the format of your page.

||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.|
||This tag tells the browser how to render a page on a mobile device. Presence of this tag indicates to Google that the page is mobile friendly. Read more about how to configure the viewport meta tag.|
||Labels a page as containing adult content, to signal that it be filtered by SafeSearch results. Learn more about labeling SafeSearch pages.|
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, case is generally not important in meta tags.
- This is not an exclusive list of available meta tags, and you should feel free to use other meta tags if they are important to your site. Just remember that Google will ignore meta tags that it doesn't know.
Independently of page-level meta-tags, you can designate parts of an HTML page not to be used in snippets. This can be done with the
data-nosnippet HTML attribute on
section HTML elements. For example:
<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. More information.
