For the purposes of SEO, it is important to have a different title on each page. I am not talking about the headings, but rather the words that appears in your web browser's title bar. You can do this very easily in Blogger.
For those not familiar with HTML, the title of the blog is located in the title bar of your Web browser. The words that are displayed in the title bar are located between the title tags in the head section as such:
<title>Blogger to the Limit</title>
</head>
The above code will produce the blog title shown in the image below:

The title of your pages is also very important for SEO purposes. When you perform a search in a search engine, the results of your search display the page titles of each page that matches your search. As you may have also noticed, some of the keywords you search for are bolded in the page titles.
What this means, is that when you create your post titles, you should use your keywords. Your post titles should then be used in the title of your pages. By default, however, most Blogger templates don't include the post title as the page title, which is why you should change this in your template.
The changes that need to be made is very easy, and are outlined below.
Changing Your Page Titles In Blogger
To change the page titles of each post in your Blogger blog to match your post titles, simply use the following steps:
- Open up the HTML layout of your blog.
- Find the term <title> which will show where your page title is written within your code.
- Replace the entire title tag with the following:
<title>
<b:if cond='data:blog.url == data:blog.homepageUrl'>
<data:blog.pageTitle/>
<b:else/>
<data:blog.pageName/> | <data:blog.title/>
</b:if>
</title>
- Save your template and view your blog. Click on a post to view the page titles to see if they have changed to match the post titles.
The above code simply checks to see if the home page of your blog is displayed. If it is displayed then the name of your blog is displayed as the page title.
If another page, such as a post, is displayed, then the name of the page is displayed first, followed by the name of your blog.
After making the change you will now have a more SEO-friendly blog that will perform better for you in search engines.
