Metadata is well defined as “Data about Data”. Metadata is data that further provides information on other data. Metadata describes a data in more defined way, so as to represent each & every detail of data. It is a data that provides resource, to ascertain whether data is a publication, web page or database. Metadata consists of data like: -
- Means of creation of the data
- Purpose of the data
- Information on Time and date of conception
- Author of data
- Network where the data was created
For example, a digital image may include metadata that describes length of a picture, the color depth, the image resolution, when the image was created, and other related data. Another example could be of a Telephone directory, through which we search telephone numbers with names or location.
In a similar way, meta tags are a great way for webmasters to provide search engines with meta information about their sites. Meta tags information is inserted in “Head” of the web pages. Meta tags play a very important role to rank a web page in search engine.
The most common types of Meta tags you’ll find on the web are:
- Meta Description Tag – This tag includes a sentence to a paragraph describing the page content. It is mostly displayed in search results under the page title.
- Meta Keywords Tag – Not displayed to viewer or in search results. Ignored by most search engines, not super important, Yahoo! used it to help include pages into search results when the text is not on the page. Misspelled keywords and similar stuff should go in the meta keywords tag.
- Robots Exclusion Tag – Used to prevent robots from crawling certain pages or your entire site.
The Meta Tag Analyzer helps in analyzing the above stated Meta Information of a web page with suitable recommendations.
