This tool can be very useful in terms of search engine optimization and ranking high on Google search.This will in turn bring you more traffic to your blog, so I advise you to use this Blogger Meta Tag Tool well.
Here is how to activate the meta tag generator in the blogger edit posts section –
1)Go to Blogger Settings > Search Preferences > Meta Tags. Make this option “Yes” and add some meta tags that are suitable for your blog.
2)Now Go to a “New Post” and you should be able to see the Search Description options in the right hand side under the Post Settings.
If you are using a Custom Template For Blogger, then you need to add the following code to your Blogger Template, just before </head>
<b:include data='blog' name='all-head-content'/>
Now you should be able to see the Meta Tag Generator Option in the “New Post” even if you have a custom blogger template.
