Do you know that title tags are the most vital elements which are playing a major role to rank high in Google? Higher page rank= more organic traffic= get more money. I started to realize about this when I saw my blog's Google Page Rank reached two although for now it is just one and half months years old.
When web robots of the world's famous search engines such as Google crawl in your site, they will always read every word in your post title from left to right. For that reason, it is important to show your post title first and then followed by your blog/site name to make sure that your blog post get easily spotted during web searches. Here is a perfect example on how it should look like.
Usually default Blogger templates do not come with a Search Engine Optimized title tags. Normally, the blog title is shown first and then followed by the post title. So, here is a simple trick to turn it around (post title | blog title).
Make sure that you've saved a copy of your template before doing this trick. Go to Layout, then Edit HTML page. Now search for this code. You can find it below <head> tag.
Then replace that code with the code below.
<title><data:blog.pageName/> | <data:blog.title/></title>
Save your template. Now, go to your blog and click any of the posts. You will see a difference in the page title.
So, you've successfully optimized your blog posts. Your page rank will not change in one or two days. Wait until your page re-indexed by Google. It will take some time. Meanwhile, keep posting original and unique content, and I am sure that organic traffic to your website will increase. Good luck.
