Your page title is one the important factor of SEO. Since Blogger has a default Page title as follows :

Blogname | Page Title

We will try to change it to

Page Title | Blog Name

So just follow the steps below :

1. Go to Layout>edit HTML in your Blogger dashboard.
2. Search for this tag: <data:blog.pageTitle/>
3. Replace this tag with the following:

<b:if cond=’data:blog.pageType == &quot;index&quot;’>
<title><data:blog.title/></title>
<b:else/>
<title><data:blog.pageName/>|<data:blog.title/></title>
</b:if>

  4. Save your template! (See, this is an easy hack!)

There you have it.. It works in my blog. This is applicable to the new Blogger Templates and not to the old one.
