But there is no feature blogger to customize the Meta Tags.
So I made some easy mods to optimize the Meta tags for Keywords, Description, Title and even customize for the Index page, post page and archive !
By default Blogger gives only the title which is :-
<title><data:blog.pageTitle/></title>
This give the output as the Title of your blog !
So to start the mod we need to identify the there types of pages i.e. Index (main page), Item page (the individual post page) and Archive ! So the code needs have 3 scenarios.
Next is the Globally available Data tags that blogger provides which is unbelievably less ! There is no post title, no post keywords. Hence we are forced to use the following
<data:blog.title/>Which is the title of your blog
<data:blog.pageTitle/>This is the Page Title.
So here is the SEO meta tag code customize it according to blog before your add it to your blog HTML.
<b:if cond='data:blog.pageType == "index"'>
<title><data:blog.title/> : Write some stuff about your blog here not too much since only 60 char is all robot read</title>
<meta name='Description' content='Describe your blog here since this is what will be shown if your index page comes in a search' />
<meta name='Keywords' content='Key, Words, Here, Dont, go crazy, only, add, relavent, keyword' />
<b:else/>
<b:if cond='data:blog.pageType == "archive"'>
<title><data:blog.title/> : Write some stuff about your blog here not too much since only 60 char is all robot read</title>
<meta name='Description' content='Describe your blog here since this is what will be shown if your index page comes in a search' />
<meta name='Keywords' content='Add, some, more, key, word, here, but, keep, it, sane ' />
<b:else/>
<b:if cond='data:blog.pageType == "item"'>
<title><data:blog.pageTitle/></title>
<meta name='Keywords' expr:content='data:blog.pageTitle' />
</b:if>
</b:if>
</b:if>To add to your Blogger blog HTML go to Template > Edit HTML
Paste the above code (after customizing) as shown in the below image
Save the template and you are done !
