This time I will talk about URL shortening.
Prerequisite
I don't recommend using minor services like "shortened URLs" that come up when you search on Google or Yahoo!. It's annoying to have your information taken from you in the background (I don't think this happens very often, though).
Which URL shortening service is the best?
There are a lot of URL shortening services. Bitly,

TinyURL,

is.gd,

00min(made in Japan)

At least in Japan, these services are mainly used.
The length of the URL
The longest URL is TinyURL, which is shortened to
Analytics and customization
Wouldn't the best one be Bitly?
The free plan already comes with comprehensive analytics, and you can use a custom domain with the paid plan.
With the paid TinyURL plan you can use a custom domain too, but the free plan doesn't have very comprehensive analytics.
00min has analytics on the same level as Bitly, but I wouldn't recommend it if you want to use a link for a long time. You'll understand why if you read ahead.
The expiration date of the link
There is no danger of links expiring on Bitly, TinyURL, and is.gd, but 00min requires attention.
The free version of 00min links expires in "2 years".

You will have to sign up for the paid plan if you want to keep using the link for longer than that.
For commercial use
It might be difficult to understand at first, but it is "the way to make a profit."
The free version of Bitly states in its terms of use that "commercial use is not allowed."
"As long as you comply with these Terms of Service, you may use the Services your personal, non-commercial purposes. Please contact us if you would like to use the Services for your business."
The popularity of the service
Today, the most used URL shortener is Bitly.
The oldest URL shortener is TinyURL.
Bring it all together
I personally use Bitly.
I'm thinking of using Youtube or NicoNico, but I don't plan on monetizing them.
