Here's a trick I just discovered. This may not be a new idea but its new to me so I thought I would share it.
Blogger.com is kind enough to pbut the blog title into the URL of your post but if you're title is too long it will cut out some of the words. This URL can be quite important in terms of google and other engines indexing your posts.
Now the interesting thing is - once you've published your post, if you edit the title the URL won't change.
So a quick tip is to write your blog and enter the important key words into the title. Save, publish, and then edit the title of your post with something more reader friendly.
