In terms of SEO you should have your Page Title first. Luckly we have an easy workaround in order to change this. Go to your Blog DashBoard and open the Layout tab, then clic on the Edit HTML link. Find the following code:

<title><data:blog.title/></title>

and replace with:


<b:if cond='data:blog.pageType == "item"'>
<title><data:blog.pageName/> - <data:blog.title/></title>
<b:else/>
<title><data:blog.pageTitle/></title>
</b:if>

After that your Page Titles will look like this:

Post Name - BlogName
