If you just installed your wordpress blog, you would notice that the first post page would have a URL of http://www.blogsnd.com/?p=1 and the 1 shows that that is the first post. This URL is called permalinks. If you have this type of URL, it is advisable to change it because
1. Hard to Show on Search Engine : – It is much more harder for search engine to show this type of URL on their because your keyword is not there. Your keyword can be any word. With this type of permalink, search engines have to search through URLs that has 1 in it. But with your keywords, search engines can rank you on their search just based on your permalinks. I have arrived at websites just through the post permalink.
2. Hard to Remember :- I can look at a title of a post and guess what the permalink is. I would only be wrong if the owner decides to shorten the URL.
How to Change the Permalink On WordPress
To change your wordpress permalink, login to Admin Control Panel –> Permalinks.
I choose Month and Year i.e. /%year%/%monthnum%/%postname%/. (You can copy and paste this in the custom box)
Some people use just /%postname%/. The would make your post to be http://www.yourblog.com/postname instead. People argue that this is good because search engines don’t have to go through something else i.e. date or category to index that webpage.
I choose the Month and Year because of blogger. Google owns blogger so it would have to make it SEO friendly. On blogger, the permalink is done by blogger. The permalink is /2009/01/postname.
