If you wants to show your Blog Post Titles followed by name of your blog, Example- If my Blog’s name is “Firetreat” and my Blog post’s title is “Show Blog Post Title along with Blog’s Name in Search Results“, Search Engine will show same blog title along with Blog Title in its search results.
First go to blogger’s Edit Template and find “<title><data:blog.pageTitle/></title>” and replace with given code below:
<b:if cond=’data:blog.pageType == "index"’>
<title><data:blog.pageName/> ~ <data:blog.title/></title>
From the above code, you can also replace the “~” sign with any sign of your choice.
