Web headings

According to a Nielsen-study (2009), the first two words in a Web headline have a huge impact on whether or not people will click on a link.

  • Used plain language
  • Were specific and clear
  • Used common words
  • Started with the essence of the message
  • Were action-oriented
    The worst links in the study:

  • Used bland, generic words
  • Used made-up words or terms
  • Started with after-dinner-speech-introduction language
