When applying for jobs on LinkedIn, recruiters and hiring managers use the platform as their ATS. So, incorporate the relevant skills and keywords found in the job description that recruiters could search for on your LinkedIn profile. Demonstrate your professional skills and what you bring. Of course, it's easy to apply for a lot of jobs quickly (and LinkedIn wants applications so it can brag to employers about how they generate a lot of leads).
LinkedIn has changed the information that employers receive when you apply for the positions they post on LinkedIn.
