Header tags are also very important if you want to make your blog search engines friendly.Many people out there don't know how to use them but as i told you earlier that i will teach you every single guide how to make your blog search engines friendly.
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,s how you do it
first check the expand widget template button.
Now look for the code
<h3 class='post title entry title'>
and a closing tag which is
</h3>
you just need to replace h3 with h1,
or copy and paste 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>
Now look for the code ]]></b:skin>
and just before the end of this code paste this code.
h1.post-title, .post h1 #Blog1 h1, #Blog2 h1 {
border-bottom:0px Dotted #000000;
border-top:0px Dotted #000000;
margin:.25em 0 0;
padding:0 0 4px;
font-size:150%;
