Are you a blogger like me who use blogger.com free CMS to write blog posts? Well, writing a permalink is as important as putting water to boil in a kettle over flame for making a cup of coffee. It tastes great when water heats up till accurate temperature. Permalink is like appropriate flame to heat up water for making a cup of coffee. By definition, a permalink is the link url of a webpage that audience refer to others and put on a web page for reference. This is the same page url that displays on the address bar in a web browser. Once a permalink is created, you can never change it. If you will change it the reference url put by others across internet for your page simply will result in an error page, and nobody want to see error page. Search engine ranks negatively such websites and blogs that have error pages. In other words (SEO Terms) it’s called broken link. Search Engine hates broken links.
