Meta tags can be created in HTML or XHTML and allow search engines to provide information about their websites. Meta tags can be used to provide information to all types of customers and each system processes only the meta tags it understands and ignores the rest. The target tags are added to the <head> section of the HTML page and usually look like this:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="Description" CONTENT="Autor: A.N. Autor, Ilustrador: I. Ilustración, Categoría: Libros, Precio: 10 €, Número de páginas: 784">
<meta name="google-site-verification" content=""/>
<title>Libros de ejemplo: libros de segunda mano pero primerísima calidad para niños</title>
<meta name="robots" content="noindex,nofollow">
Meta tags is a label with great importance for the indexing of our content allowing indicate to the principal seach enginer the relevant information of our website as: the (meta description) allows to create a summary of our web content no more than 320 characters , (meta robots) It allows us to indicate if we want our content to be indexed or not, (meta keywords) allows us to indicate keywords of our website that are directly related to the content of our website and other tags that we could use according to our needs.
Additional notes:
Google can read meta tags similar to HTML and XHTML, regardless of the code used on the page. But not in the verify tag, meta tags are not usually case-sensitive.
The meta tags that are included below are not the only ones available and you can use others if they are important for your website. Another important fact is that Google ignores the goals labels that do not know.
Google understands the following meta tags (this list is not exhaustive):
<meta name="description" content="A description of the page" /> |
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 |
<meta name="robots" |
content="..., ..." /> |
These meta tags control the behavior of search engine crawling and indexing. The 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 |
<meta name="google" content="nositelinkssearchbox" /> |
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. |
<meta name="google" content="notranslate" /> |
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. |
<meta name="google-site-verification" content="..." /> |
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. More information |
<meta http-equiv="Content-Type" content="...; charset=..." /> <meta charset="..." > |
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 |
<meta http-equiv="refresh" content="...;url=..." /> |
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. |
<meta name="viewport" content="..."> |
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. |
