What this link checker can and cannot tell you
This link checker reads the address you paste and reports the real domain, the path and any tracking tags. It warns about characters from mixed alphabets that can disguise a look-alike domain, text before an @ that hides the real site, and a missing HTTPS, and it says whether the domain is a known link shortener or a CTAurl action domain.
The link checker does not follow redirects, because a web page cannot request another site and read where it sends you. For a link on a generic shortener, it can tell you only that the real destination stays hidden until the link is opened.
How do you check a short link before you tap it?
To check a short link, read the domain first: it is the part between :// and the next /. If the domain mixes alphabets, imitates a brand or belongs to a shortener that hides the destination, do not tap it. Open the sender's official app or a site you have bookmarked instead.
A random string in an SMS can look suspicious. A domain that names the action tells readers what the link is for.
Short links are part of the reason. The Council of Anti-Phishing Japan reports that attackers route victims to phishing sites through short-URL services and other redirect services (monthly report for June 2026, published July 2026). Many shorteners offer a preview page. On CTAurl, the action domain itself says what the link is for: a buy-it.now link should lead to something you can buy, and one that does not can be reported as abuse.
