OP here. I've had basically no response from the various third-party recruiters I've contacted, compared to at least some response to my direct applications to specific positions. Letting recruiters do your job search for you sounds like a great way to go though if that's an option for you. I've gotten certificates in the past and used to put them on my resume or LinkedIn, now I just leave them off. They're so minor compared to the rest of the stuff on my resume that realistically they aren't going to move the needle. In fact, no offense intended, but it feels like a junior move given my existing background, like putting my high school on my resume. I can see them being really helpful for some people, though.
