You can easily change the title tag in your blogger template, so you can get an easily SEO optimizing here. Also this small optimizing can give you a better ranking in search engines. For some of my other blogs this has given me a better ranging.
After the change the title in the browser will be this:
Front-page:
Blog title will be showed.
Item page - one post showing:
Post title - blog title.
Blog Archive:
Blog title: archive title Blog Archive.
For changing the code go to your template and find the following code:
<title><$BlogPageTitle$></title>
This code is you have to place where the old code where.
<MainPage>
<title><$BlogPageTitle$></title>
</MainPage>
<ArchivePage>
<title><$BlogPageTitle$> Blog Archives</title>
</ArchivePage>
<ItemPage>
<Blogger><BlogItemTitle><title>
<$BlogItemTitle$> : <$BlogTitle$>
</title></BlogItemTitle></Blogger>
</ItemPage>
When you have changed you code then save your template and you have just made a SEO optimizing of you blog.
It's a good idea to save a copy of yours template before you try to change it, so you have an original copy to go back to.
