At least 11 (out of this 12) broken links must be detected to get placed at the shortlist.
The following broken links are ...
This broken link checker seems to meet the criteria for the shortlist. However during the tests I discovered that there isn't a free version of Linktiger. It is advised to use another free broken link checker.
However ... Linktiger is a very interesting link checker. The reason is that you get at a regular base (daily or weekly) a mail with the number of broken links found at your site. I have to say, such a mail is a perfect trigger to repair or replace broken links. Hence I decided to test the quality of Linktiger in depth.
With Linktiger the following sites are tested:
The average speed of this broken link checker is not relevant.
The maximum number of links being tested is 1000 during the first free month.
In fact the number of links being tested depends on the pricing plan you choose (as mentioned before Linktiger isn't free). It varies from 1000 links to 3M+ links.
Slow websites are tolerated when they respond within 20 seconds.
Unknown status codes (LinkedIn!) are considered an error.

Due to the fact that Linktiger mails you the result, the test speed is not applicable. Hence the max score is 82 instead of 87. Based on the results above 57 points (out of 82) were earned. That gives a score of 70%. Note that this score increases when you use a larger paid plan.
As always, it depends on your requirements whether this is the ideal linkchecker for you. At least a pre is the regular mail you get from Linktiger.
The Dead Link City score is 57/75.
