Applicant tracking systems extract plain text from your file.

Ignoring instructions (word limits, questions to answer, portfolio links).
Burying the role title below a generic introduction paragraph.
Sending identical Machine Operator cover letter text to multiple employers without rewriting the company paragraph.
Copying the job description into your letter without adding proof you performed the work.
Using "To Whom It May Concern" when the hiring manager name is on LinkedIn or the posting.
