Gotta be honest, I'm getting real sick of seeing "View my verified achievement" posts on LinkedIn. I have gotten a few certifications, but I have never posted them on LinkedIn because its irrelevant for 98% of my peers. How about simply telling your relevant peers of your so called achievement. Your manager would probably interested in knowing, but most of your 500 followers sure ain't. You can still put your certification on your LinkedIn profile for the recruiters to glob over while doing the rest a favor.
