I mean, it’s not like search engines are really finding these URLs, right? In short, if you’re hoping that links you tweet will generate link credit for your web site, you want a service that issues a 301 redirect. That means link credit does not get passed on to the long URL. If that’s issued, search engines assume that the short URL is the “real” URL and just temporarily being pointed elsewhere. In contrast, a 302 redirect is a “temporary” one. Since it’s a permanent redirect, search engines finding links to the short URLs will credit all those links to the long URL (see the SEO: Redirects & Moving Sites section of the Search Engine Land members library for more about redirection).

Below, issues to consider and a breakdown of popular services, including recommendations and services to avoid (the new DiggBar being one of these). ![]() When every character counts, these services reduce long URLs to tiny forms.
