URL not accepted - Blog address guidelines

If a URL is not accepted, there are the following possibilities,

1. The address is taken already by someother blog owner. (Unfortunately there is nothing we could do about it)
2. The address you entered is invalid.

If it is Case 2, we can do something about it.


Blog Address aka URL Guidelines

1. URL must be of limited and precise characters.
It's recommend that, a URL must be short and precise. Lengthy URLs would not make the followers of your blog happy as they will have to remember it.

2. URL must not have special characters other than hiphen (-)
A URL must not have any special character like "something@somewhere.blogspot.com" or "some.thing.blogpot.com" or "something*something.blogspot.com"
Whereas a URL can contain a hyphen -> "something-something.blogspot.com" or "something-at-somewhere.blogspot.com"

3. Descriptive URLs
Instead of having a URL as "your-name.blogspot.com", you can have the URL having a small hint about what the blog is.
