What are meta tags for Seo?
META tags are HTML instructions that are used to provide information on our website to search engines and Web search robots that use this data to create its indices. This information is known as meta-information.

These tags are not visible to visitors or sailors, or influence the design of web pages, but their use is essential for web page data is transferred correctly to the trackers and search engines, we can improve our position in the search engines and ultimately, we attract more visitors to our site.
Allow Meta tags provide the following information to our website: language, author, title, description, keywords and other attributes that we want to know the search engines to index our site correctly, was placed at the head (head) of the website index (index or default). If your website uses frames (frames) are meta tags on the page where you set the frames.

Basic elements that shape the META-TAGS

Each META tag specifies a property-value pair, where the attribute "name" which identifies the property and 'content' of the same value. For example the label specifies <META name="author" content="My Name"> authorship and the author's name.
Attribute "HTTP-EQUIV" can be used instead of the attribute "NAME". I.e. http-equiv = name.

Some tags META

1. Western European Encoding

<meta content="text/html; equiv="Content-Type"Charset=iso-8859-1">

Define that our website is Western European. This meta-label correctly displays special characters of European languages: N, C,...

2. Language of the page 

Sets the language in which the website is. In the case of the Castilian language syntax is:

<meta name="DC.Language" SCHEME="RFC1766" CONTENT="Spanish">
Or: <meta http-equiv="Content-Language" content="es">

3. Title

Currently the title tag (title) of the website is one of the most important factors for positioning on the Internet.

4. Author 

Name information: <META name="author" content="Name of author">

5. Copyright

It is a label that provides information about the copyright of the creator of the content or design. Some search engines like Altavista, Infoseek and Hobot begin to consider it which could afford to have guarantees about the content of the pages.

The syntax is: <META name="Copyright" content="©publiceuta">

6. Keywords

These are the words, along with a description of the page, which search engines use to index our website so we want to choose them carefully. Depending on our search engine keywords submitted our prominently or not.What is the optimum keyword density for a page?

Interesting to think of the words that best define our company or in the words typed on a search engine like Google if we find our own page.
should know that search for the plural words containing the same words in the singular, IE when we use plural keywords in our page will be indexed when someone performs a search with those keywords in the singular.

The keywords that best define our business or interested page singular and plural repeat because the search engine will be found two matches for those keywords.
Seekers criminalizing there repetition of words so that should never be repeated more than three times the same word.
Fewer words will not use four-letter unless forming part of a sentence. These may include complete sentences as keywords, for example: "sale of flats."
Some search engines index only interprets the first seven or keywords and if more of all discarded.

The syntax of this tag is:
<META NAME = "keywords" CONTENT = "word 1, word 2, word 3, word4, word 5, word6, word 7">

7. Description

This tag contains the description of our website and many search engines display this description to mariners. In addition the use of search engines with keywords to index our site.

We'll use phrases that best describes our care to use words that are contained in the keywords. It is worth repeating words, as many robots as penalized. Try to use the minimum amount of articles and prepositions possible. Use capital letters only when speaking of places or people, Should not use more than 25 words. Most search engines only take the first 150 characters of the description so it should be concise and effective.

If we do not include this tag, search engines can simply submit our site title or show the rider a string 150 characters of our website which in some cases gives a misleading picture of our website.

Instruction syntax is: <META NAME="description" CONTENT="description of page">

As some robots can not use META tags include a descriptive comment of our website, with no more than 150 characters, after the meta tags, with comment tags (<! - / / would your descriptive text here / / -!>).

8. Permissions for Robots

This label instructs robots automatically visiting our site. The attributes you can use are:
all | none | index | noindex | follow | nofollow
ALL means that all files are indexed. NONE any files. INDEX means that the page can be indexed by robots, NOINDEX would otherwise. FOLLOW indicates to follow the links from that page to another, NOFOLLOW otherwise.

Usual syntax is: <META name="robots" CONTENT="all | index | follow">

Words we allow robots to index (index) all files of our website (top) and follow the find links to other pages indexed (folllow).

<META name="robots" With CONTENT="index | nofollow"> only be indexed the page.

9. Revisit 

This tag tells the robot that you revisit this page last 'x' days, either because their content will change or they want to keep it updated. It is an interesting label for pages frequently updated information.

The syntax is: <META name="Revisit" content="X days"> where X is the number of days.

10. Browser Cache 

For browsers that do not use data that are stored in its cache (memory) and have to see the current picture of our server in use:

- For Microsoft Explorer browser: <META HTTP-EQUIV = "Cache-Control "CONTENT =" no-cache ">
- For Netscape browsers: <META HTTP-EQUIV="Pragma" CONTENT="NO-CACHE">

11. Set-Cookie

This is a way to place a cookie on the user's browser. If using a cookie expiration date is considered permanent and will be saved to disk, otherwise it will be considered only for the current session and will be deleted when you log off.

The syntax is: <meta HTTP-EQUIV="Set-Cookie" CONTENT="cookievalue=xxx; expires=Wednesday, dd-Jan-00 hh:mm:ss GMT; path=/">

12. Automatic loading of pages (Refresh tag)

This function is very useful because it allows the browser automatically sends us to another page in a specified number of seconds, without the user having to do anything.

The syntax is: <META HTTP-EQUIV = "Refresh" CONTENT = "5", URL = ""> that is load the page after 5 seconds.

If we want to be "cool" automatically use the same page: <meta http- equiv = "refresh" content = "30"> and our page will automatically refresh every 30 seconds.

13. Rating 

The label "rating" is used to define the audience it addresses us, especially to tell whether a site is appropriate or not for children.
values ​​for this tag are: "general" for all audiences, "14 years "to public for over 14 years," mature "for mature," restricted "for adults only" safe for kids ", suitable for children.

14. Distribution 

Label "distribution" defines the level or degree of distribution we want for our page. It has three values: "global", indicates that the page is directed to everyone, "local" indicates that it is intended to document local distribution, "IU" (Internal Use), not for public distribution.
If we use this label, and pretend that our site is distributed throughout the world, we always give the value 'global'.
