Metadata is generally information about your data, when it comes to html,we have meta tags (<meta>)
We can have meta datas for HTML as below :
<meta name="description" content="Free Web tutorials">
<meta name="author" content="Hege Refsnes">
Keyword meta tag and google :
From September 2009 ,google has stopped evaluating tag "keywords" from web pages since they can be easily abused and search engines can be fooled,say like you have a website with keywords "computers,rajus tutorial" , any other user can also use the same keywords for their website also ,then it would be a cause of concern for original author.
But at the same time you can use following :
<meta name="description" content="A description of the page" />
If you ask whether to have meta tags same in every page then i would say , "No"
Try to add unique descriptions in each page or leave to google to create based on page snippets
- Search engines don’t use meta descriptions as a ranking factor.
- The best meta description length is between 150 and 160 characters.
- If a page has no description, search engines will return a snippet base on the content of the specific page, relevant to the search query.
