This helps search engines show searchers the topic of each post you've written. Otherwise they may just show the name of your blog for every post. After this change, search engines should show searchers for the actual title of the blog post on the search engine results page.

You will find this in your blogger edit options.

Go to layout and at the top go to edit html.

Here's what you do. First, search for this text:

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

And

replace it with this text:

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

I hope this hack of code is useful for my blogger readers.....
