Updated Nov 2, 2026 · Data: O*NET 31.0 · advice labelled as advice
Quick answer

A strong Web Developer cover letter is three or four short paragraphs on one page. Name the role and where you saw it, then prove two core parts of the job, such as write supporting code for Web applications or Web sites and evaluate code to ensure that it is valid, with a result you can check. Show programming and critical thinking through an example, and close by asking for a conversation.

Advice
  • Listing tools you haven't used: the tools above describe the job, not you.
  • Describing duties instead of results: “Write supporting code for Web applications or Web sites” is the job, not an achievement.
  • Apologising for limited experience instead of showing related tasks you have done.
  • Ignoring Computers and Electronics, a knowledge area O*NET rates important here.
  • Ignoring deadlines when the job runs under time pressure (O*NET work context).
