How to add meta tags to blogger blog

And do we have any benefits of them.
First of all let's say what are they.

What are Meta tags 

Meta tags are small html codes which you place in blog html to help search engines to easier  index your blog.
I read many articles where authors are saying that meta tags are not important anymore for web rankings .Google is not using keyword in web ranking for years now But I believe also that everybody of you who have blogs will put them in html template anyway why not it cant make harm ,I did it every time. ,but its very important to bring them back when you change your template also as that now you have a templates with built in meta tags where is all you have to do change it with your information
One for shore is that you cant depend only on meta tags, that would be only a small step in building your own space under the net sun .So lets see some examples of meta tags.

<TITLE>Type your blog name </TITLE>
<META name ="description" content=" description of your blog,which will appear in Google's search results">
<META name ="keywords" content="your keywords ,separated by commas">
<META name ="language" content="language of blog">

And there is  more meta tags you can place it but I just cant write about them today ,lets say just I'm to lazy.And I really don't know is there any help of them like is Author name ,Geo place name , even placing Meta name robot when you probably do that already in search preferences, see  how to add robots txt in blogger blog

Now ,how to put these meta tags  

in your  HTML template .Go to Dashboard of your blog,than to Template click on edit HTML ,click Proceed .Now, you have opened your template and in  <HEAD> section ,that is in upper side of your template </HEAD> place your meta tags .

Or you can just place your Meta tag description in blogger dashboard , so how to do that
