Actually I am reading this information in other forum discussion and they say it is important to create meta tags in blogs/site ..Since I am new I have no idea if it is indeed important or not that is why I would like to know about it..But anyway I am glad to hear the other side of meta tagging so I am not going to force myself in placing it in my blog
"Getting a well crafted meta description to be displayed as the Google snippet with a call to action can drastically improve your click-thru-rate when your URL appears in the SERPs." Indeed, that's a very good reason to use it. Most of the time it converts searches into unique visitors.
somebody told me , keywords also must put together at meta description.. somthing like this , example ... is that true ?
At the view point of search engine optimization that Meta tags are very important because it's work as informer to search engines. It's very simple HTML attributes which are easily available on internet, just go through with them and put u r selected meta tags in that HTML code and upload it on server, that's sheet.
