Removing default title tag from bloger

if you create a new blog in Blogger, the default behavior for your pages' titles is as follows:

1. Blog Home Page Title: corresponds to your blog title.
   Post Page Title :  is formed concatenating your blog title, a colon-space (“: ”) and your current post title. For example: the page title of this post should be by default “Yanniel's notes: A SEO advice for Blogger: Remove the blog title from the post title”.

A proper way to avoid these SEO issues could be:

• Blog Home Page Title: corresponds to your blog title.
• Post Page Title: corresponds to your current post title.

To achieve this perform these easy steps:

1. Open your Blog Template HTML editor, available thought Dashboard-> Design->Edit HTML.
2. Find the string <title><data:blog.pageTitle/></title>
3. Replace it with:
    <b:if cond='data:blog.pageType == "index"'>
      <title><data:blog.title/></title>
    <b:else/>
      <title><data:blog.pageName/></title>
    </b:if>
4. Click the Save Template button. Done!

Your post title is no longer: “Yanniel's notes: A SEO advice for Blogger:
Remove the blog title from the post title".
