There is no policy for Blogger, about blog title and URL - either that the "words" in each can, or cannot, be the same. Some SEO experts suggest benefits from having relevant words, in the URL - and some blog owners confuse this advice, as suggesting having identical titles and URLs.
Be wary of advice that references websites, in discussions about blogs. There are subtle, but real, differences between dynamic blogs, and static websites. Rules that may be important for websites may not be relevant, for blogs.
The most obvious differences, between blogs and websites, are found in content - but blog design may have similar differences.
SEO strategies, for a dynamic blog, and a static website, will be different. Dynamic blogs have many exciting opportunities.
I have suggested that it may not be possible to make the blog title and URL the same, in all cases.
- Most subjects won't be unique. Many blogs will share a subject.
- The blog URL must be unique. Two blogs cannot share a URL.
- The blog URL will have restrictions, in characters allowed.
Most subjects won't be unique.
Any popular subject will have many blogs published to that subject. Every blog, about the same subject, will have a different URL.
If a blog is published, to a subject which has no competition, it will be a subject which interests nobody. A blog with no competition will likely have no readers.
The blog URL must be unique.
Two blogs cannot share a URL. One URL == one blog.
That does not mean that title and URL cannot share "words" - just that it's not possible that they will be identical, for all blogs.
There can be only so many ways to mention your favourite, top level movie star, in the title - and there will be even less ways to construct a unique URL. A less famous celebrity, on the other hand, will have less blogs to compete - and less readers also.
The blog URL will have restrictions, in characters allowed.
URLs can use only certain characters.
a sequence of characters beginning with a letter and followed by any combination of letters, digits, plus (+), period (.), or hyphen (-)
That syntax is somewhat limited, compared to characters that may be used in blog titles - and in the blog description and content. Less choice of syntax leads to less possibilities for uniqueness, while providing some clue as to the purpose of the blog.
A Blogger blog is dynamic - and you SEO using content.
Blogger blog content is dynamic. You get more performance, from a blog with regularly published, unique content, that's informative and interesting.
You get less performance, from imaginative naming strategies. Acme does not make an "SEO Kit", for Blogger blogs.
Some #Blogger blog owners worry about the need to publish a blog with the Title and URL containing the same words. Some suggest that having identical words is necessary, others that having identical words is not permitted.
Fortunately, neither possibility is relevant to Blogger / Google Content or TOS regulation. Blogger and Google care about content quality - and prohibit scraping and spam.
