Performance Marketing Expert
Marketing is all about your A/B Testing and Strategy. Even "Pro"fessionals fail without a proper strategy. And if your strategy includes publishing 5 Blogs in a week or generating 50 Backlinks in a day, that ain't going to help and ultimately you'll end up dissipating your allocated funds.
Online Marketing isn't that course you did or Blog you just read or Test you gave to Google. Its more than that and require strong Analytical skills.
