Just like any other top CMS, like WordPress.org, blogs powered by Blogger also have the feature to add Meta Description tags to every page, you just need to enable some settings, in this tutorial let us see how.
Check for the required codes
1. First and foremost thing that you should do is to check for the required code which will actually add the Meta Description tags to your Blogger templates. So go to “Template” tab of your blog from the dashboard and then click “Edit HTML” button. Now find the the below code.
<b:include data='blog' name='all-head-content'/>
If the above code is there then you don’t have to add any other codes. But if you have edited and customized your templates where the above cannot be found then only add the below codes after <head>.
<b:if cond='data:blog.metaDescription != ""'>
<meta expr:content='data:blog.metaDescription' name='description'/>
Turning the feature On
From your blog’s dashboard go to Settings > “Search Preferences” tab > Meta tags > Description > click “Edit” and select “Yes” for “Enable search description?”. Within the textarea write a brief description about your blog. This will add description Meta tag to the homepage.
