Understanding Online Job Applications

Online job applications differ significantly from traditional ones. Employers often use Applicant Tracking Systems (ATS) to filter candidates before a human even reads the application. This means your cover letter must be both human-friendly and keyword-optimized.

Key Characteristics of Online Job Ads

Your cover letter should directly reflect these elements. For example, if the job requires “project management skills,” you must mention and demonstrate that skill clearly.

Traditional Application Online Application
Printed documents Digital submission
Less competition High competition
No ATS filtering ATS keyword scanning
Beginner Mistake #1:

Sending the same generic cover letter to multiple job postings without customization.
