Update: I didn’t realize it before until some fellow readers notified me about it. If you change the post title from H3 to H1 tag then every post title on homepage will have h1 tag. It is not recommended to have more than one H1 tag per page according to Google. Inside the post or pages it is OK. What you can do is to limit the post on homepage to one so that only one post will appear on homepage and hence there will be one H1 post title on homepage. I am trying to figure it out on how to display title with h3 tag on homepage but h1 tag inside the post. If I get the solution then I will update this post.

By default blogger blog’s post title is given h3 tag which is not search engine friendly. You can put your post’s title in h1 tag for better ranking. It not only it gives you better ranking in Google, h1 tag makes post’s title look bigger and easily readable. Post title is very important and is considered as the centre of visitor’s attraction.

So, here’ how you do it:

Look for the code

<h3 class='post-title entry-title'>

You will find two tags:

An opening tag which is

<h3 class='post-title entry-title'>

and a closing tag which is:

</h3>

For example:

You just need to replace h3 with h1 which will make the overall result look like this:

<h1 class='post-title entry-title'>
     <b:if cond='data:post.link'>
       <a expr:href='data:post.link'><data:post.title/></a>
     <b:else/>
        <b:if cond='data:post.url'>
          <a expr:href='data:post.url'><data:post.title/></a>
        <b:else/>
          <data:post.title/>
        </b:if>
     </b:if>
      </h1>
