Bit.ly

The gadget spec URL could not be found
Bit.ly is a simple URL shortener.

Bit.ly is extremely fast with realtime reporting, but it has two major limitations
  1. Once you set the destination URL, you cannot change it
  2. You cannot create independent click-counters to the same URL

Spam Protection

Four kinds of protection against spam and malware
  1. Transparency

    A preview plug-in shows users the long urls behind shortened hashes

    Append a + to any bit.ly link to see more information, like the destination URL

  2. Real-time spam-filtering services like SURBL and Google Safe Browsing

    Uses multiple filters, and reaching out to companies with promising technology

    When a link or domain is flagged as spam, shows an interstitial warning page, like Firefox (freezing or deleting bit.ly links would make bit.ly seem broken)

  3. Don’t recycle hashes

    Users cannot change mappings once they have been created (a bit.ly short URL will take you to the same destination on every click)

    Spammers cannot bait and switch by offering quality content first and then malware

  4. Report spam

    Email spam you find to abuse@bit.ly

    If you are incorrectly marked as spam, send a note to support@bit.ly and they will investigate

    Bit.ly does not maintain a whitelist of its own, so if SURBL has marked you as a spammer, you will have to go directly to SURBL to get off the block list

Background

12-people development team

4.2 billion clicks a month
growing 25% a month
Owns 80% of twitter url shorteners

Best of the best practices
All about infrastructure, scale and redundancy
Co-located in same places Facebook and Twitter

Automated clicks are ignored (no Google bots), only real users are counted




Bit.ly Enterprise

Can connect with the users who use your shortened links

eg
^-- Bit.ly enterprise users

Seeing tgn.ly inspires more confidence than bit.ly

The info page (+ suffix) will always redirect to bit.ly

Everything on tgn.ly will work on bit.ly, but nothing on bit.ly will work on tgn.ly

Benchmarks

Bit.ly enterprise will compare sites similar to yours (not individually identifiable) to an average

Limitations

Cannot change destination URL
By design, every bit.ly link is a 301 redirect (permanent move)

Only solution is to create your own redirect service behind bit.ly
