First and foremost head on over to your settings page and make sure you have these settings are all on yes:
Settings -> Archiving -> Enable Post Pages? = Yes
Allows single pages for every post.
Settings -> Formatting -> Show Title Field = Yes
Allows me to specify Title when posting.
And then go to your blogger template page, as always back it up in case you have some issues with this (copy & paste the code to a local txt file), and after the head tag include add simple code:
Code:
<mainpage><blogger><title><$BlogPageTitle$></title></blogger></mainpage><itempage><blogger><title><$BlogItemTitle$></title></blogger></itempage>
Now go to a post page and look at it's title. Search engines will also list your posts as their titles not by the title of the blog like normally.
Thank You
