QUESTION
What are they and what are the meta tags?
ANSWER
The meta-tags are special HTML tags through which you can specify information (indeed, meta-information) on gender and type of web page. The full list of meta-tag is available in the official documentation W3C. The first analysis to be made on the meta-tag is that in order to a good placement on search engines, their value is rather minimal. Many experts even consider their value nil. Sfatare commonplace that the meta-tags serve to get good positions on the engines is difficult. Despite the continuing information, tests and studies conducted by research laboratories EES remains opinion of many webmasters who do not serve a website quality but enough to fill meta-tag to “climb the positions.” A few years ago, when technology development of algorithms search engine was not very refined and potential of computing and storage were very limited, the spiders concentrated its operations to reading exclusive header HTML web site pages to be indexed and few hundred characters ASCII text. To the aid of spiders ran precisely meta-tag written by webmasters in HTML, through which supplied a summary of the information contained on the page that esaurirne the necessary information to the spiders themselves. Over time, however, there has been an indiscriminate use of meta tags, with misleading information for search engines, with the aim of sviarne action and gain positions for a period also not related to the website. Such behaviour is not correct today led the search engines to relegate meta tags in positions of secondary importance. It remains important, however, their use to build websites usable. The meta-tag dedicated to the search engines are basically three:
Description
(whose syntax is: <meta name=”description” content=”inserire here descrizione”>): The meta description tag allows you to enter a description of the content on the webpage. That description should be brief, a summary of few words, preferably focusing on keywords on the page. The contents of the tag description – if well product – is often reported from the engines in searches. Even the tag for the above description applies for the title of the page. Its value is double. Used as a means of communication will intercept traffic and therefore qualified producer of value for the site owner. So not a lot of keywords but a genuine brief description of the page, with content appealing and useful for the audience to which it is put.
Keywords (whose syntax is: <meta name=”keywords” content=”chiave1,chiave2,chiave3,chiave4,etc”>): meta-tag keyowrds allows you to specify a list of keys on the topic of web page .
Robots (whose syntax is: <meta name=”robots” content=”vedere documentation W3C”>): meta-tag robots is designed to provide additional information on the web site content, “inviting” the crawler to take a conduct during the visit and analysis of the page.
The meta-tags are inserted into the HTML in the document, or between the tags and.
