Increase Rank with Meta Tag || Important for SEO


Overview of important meta tags

Meta tags are the encoded information found in the header of an HTML document that specifies the metadata. These are not visible on the web pages. User agents such as browsers or search bots are the only ones that can read meta tags. The purpose of these meta elements is to deliver additional data to a website to make it easier to parse HTML documents as well as manage file content. The meta tags of HTML pages generally follow the following structure: attribution of a defined element then that of its content. So the metadata schema is as follows:

<meta name = “Element name” content = “a description of the page” />

While HTML page metadata played an important role in search engine optimization a few years ago, its influence on the ranking of Google and its competitors has now become minimal. However, it is appropriate for website administrators to keep the information in the HTML headers and drop the full metadata there. Indeed, they are still relevant for metasearchers. In addition, meta tags are used to define instructions that are used to control search robots. 

Important meta tags

The list of possible elements in the HTML header is long. Beyond essential data such as page titles, descriptions and definitions of the characters used, the header (the title of the files in HTML) makes it possible to deliver complete information to user agentsThus website administrators can define keywords or give page themes via meta tags. In addition, it is necessary to name the editors or even the editors or else mention the information relating to copyright in the tags. Not all of this information is relevant for interaction with web browsers and search bots. It is different for the meta tags which control the behavior of user agents by prohibiting indexing of the corresponding HTML pages or by preventing crawlers from following outgoing links. The following selection will outline the most important meta elements and their use in the operation of a website. 

Title tag

The <title> is not a meta element per se, but rather an independent HTML tag. However, because of its interaction with user agents, it is often associated with metadata. As a required part of the HTML header, the <title> is usually placed before all other meta tags. Read by web browsers, it appears in a tab or window bar as the default name when creating bookmarks and in history. In addition, all the big search engines use the <title> tags as titles of articles in their search results or SERP (for English search engine results page ).

The <title> is one of the many positive factors (around 200) for the ranking of a page in an organic search. In the context of onpage optimization , you have to pay attention that a <title> does not exceed 55 characters in order to be read by search engines. In addition, it is advisable to place the main keywords of a website in these <title> tags. Here is an example of the possible type information:

<t<title> The main meta tags and their functions | ETHICALTH </title>

Character encoding

If special characters are not already defined in the HTTP header , it is recommended that you pass this information using HTML. The aim is for example to make accents appear without error in the text. In order to specify special characters or character encoding, use the following meta tag:

<met<meta charset="utf-8"/>

Metadata is also relevant if a browser does not receive HTML files over HTTP but directly from the hard drive.

Description of pages

The description (also called meta description tag) is a space dedicated to writing a short summary of the content of the Internet page. Since this meta tag is taken into account by the most famous search engines such as Google or Bing in their search results, it is advisable to be very careful in their writing. Due to its importance on the click-through behavior of users for internet searches, description is one of the essential meta tags of SEO HTML pages.Web site administrators should be careful not to use more than 160 characters, including spaces. Otherwise, some characters may be cut in the SERPs and the description may only appear in part. The meta description tag is primarily intended for the Internet user and must therefore illustrate a concise summary of the content of his website. For Google, administrators must ensure that each page of their website has an individual description and that it delivers precise information about the content offered. This text has obvious added value for Internet users and helps site administrators to increase their click-through rates when searching on the Internet.

<<meta name = "description" content = "Meta tags encode HTML page information for browsers and search engines. But what data is really important?" />


Meta keywords tags (or meta keywords tag) allow website administrators to define their keywords for a search program. It is through this stored information that an Internet user searching for keywords in a program’s database receives the appropriate HTML pages. These meta tags were previously essential for SEO and were the key element in early search engine rankings. Today, this meta element is kept out of the calculation of Google’s ranking factors because it is easily manipulated. The Californian giant’s other competitors such as Bing also place little importance on keyword meta tags. Their relevance to a website’s search engine optimization is the equivalent of zero.

The fact that keywords stored in metadata have little or no positive impact for ranking in Internet searches does not mean that misuse of these meta tags is not penalizing. Choosing a keyword implies a certain sensitivity. Keyword stuffing should be avoided.) but also meta-keyword tags which are not related to the content of the corresponding web pages. Since search scripts as well as local metasearch engines sometimes rely on information present in meta keyword tags, it is more than ever advisable to choose keywords that are well related to the subject. Some tags are separated by a comma. A keyword phrase can be made up of several elements.

<meta name = “keywords” content = “keyword 1, keyword 2, keyword 3” />

Author and copyright (author and copyright)

The “Author” and “Copyright” meta tag allows website administrators to specify in the source code of an HTML page who created the page in question and who is legally responsible for its creation. content. On some content management systems (CMS, English glad managment system ), the author tag is automatically inserted and the name of the person who last worked on the page is always named. This has the advantage that administrators can see in the source directory which manages which page. These two meta tags are optional in French law.


<meta name = “author” content = “author name” /> <meta name = “copyright” content = “copyright owner” />

Information for web crawlers (robots)

One of the challenges of meta tags is to provide indexing information for search engine crawlers. These are defined at the page level via meta robots tag data. Using the following meta tags to determine whether a page is added to a search engine index is now possible in SERPs on the Internet. In addition, you will be able to see if outgoing links are followed by crawlers or if they are ignored. Bot metadata is one of the essential meta tags in SEO.


To allow indexing of a page in a search engine, use the following meta tag: 

<<meta name="robots" content="index"/>

Since indexing web pages is the standard behavior of web crawlers, this data is usually unnecessary.


If an HTML page is not added in search engine indexes, you will need to define it explicitly. The following meta tag prohibits the search tool from transmitting the contents of an HTML page to another database:

<meta<meta name="robots" content="noindex"/>

The “robot” attribute is intended for all search engine indexing robots. The “noindex” attribute contains the information that allows indexing to be blocked. Prohibiting indexing only for a few robots is possible by choosing a different attribute name such as “googlebot”.


Following an outgoing link from a web page is part of the standard behavior of crawlers. In this case, the metadata robots can be written as follows:

<meta na<meta name="robots" content="follow"/>

This meta tag is basically redundant since the crawler of the main search engines always follows hyperlinks as long as nothing else is specified.


If you want to prevent a search robot from landing on underlying pages of a website or other domains, then here are the meta tags to register:

<<meta name="robots" content="nofollow"/>

The crawlers treat the web page as if the possible links did not exist. However, meta elements do not prevent search robots from transmitting the contents of HTML files to the database.

The Index / Noindex and Follow / Nofollow meta tags can be used both alone and in combination. It could thus be envisaged that a page could be added to an index but that hyperlinks are ignored by the crawler. The two actions of the search robot can be either blocked or allowed:

  • <meta name=”robots” content=”index,nofollow” />
  • <meta name=”robots” content=”index,follow” />
  • <meta name=”robots” content=”noindex,nofollow” />

HTTP equivalents

Thanks to the “http-equiv” attribute, the meta elements can contain equivalents to the information present in the HTTP header. This information is read, for example, if the Web server is not configured accordingly. The rule is that an identical header is preferred over meta tags of HTML pages . 


To ensure the internet is fast, it is common to put web pages on proxy servers or in a browser’s cache in order to load them faster. This process can be avoided thanks to the “cache-control” meta tag and the no-cache content:

<meta http-equiv=”cache-control” content=”no-cache”/>

Web pages with this tag must be loaded on every page request. This slows down the download of the page but it can also be relevant if the content of a web page is constantly changing.


Instead of completely blocking the cache, the “http-equiv” attribute gives you the option of setting an expiration date for the recovered HTML files . For that, here is the meta tag to use:

<meta http-equiv="expires" content="expiration date in seconds"/>

Here are the HTML pages that can be affected by meta tags. Once the time period is set, the browser should load the HTML documents from the original address. If contents are loaded from this page, an expiration date is selected from 0 seconds. After 12 hours, Internet site administrators select 43,200 seconds accordingly.

<meta http-equiv=”expires” content=”0″/>

<meta http-equiv=”expires” content=”43200″/>

You can also set durations, including dates and times. These must be specified in international format and at Greenwich Mean Time.

<meta http-equiv=”expires” content=”Sat, 07 Feb 2016 00:00:00 GMT”/>


The meta tags including the attribute “http-esquiv” allow to create a simple form of transfer. Similar to the Expire tag, Refresh defines an expiration date. When this limit is exceeded, user agents such as Internet browsers or web crawlers are transferred to a predefined URL. This code example shows a transfer in 10 seconds to the ETHICALTH home page:

<meta http-equiv=”refresh” content=”10;url=”/>

Since the Refresh meta tag does not work under certain browser settings, the World Wide Web Consortium (W3C) recommends a server-side implementation using  HTML 301  rather than a transfer via a meta tag.

Meta tag generator

There is a plethora of meta tag generators on the internet for website administrators to quickly and easily create meta tags. The one on the SEO Tools  site is very practical. To do this, you will need to insert your information only in the generator mask. This software then translates the data into source code. You can then transpose them directly into the HTML header of your web page.
