In case you missed it — and there’s probably no way you caught all 100 — we kicked off 2013 with a #100PPCtips100days series on Twitter, and we’ve recapped them by category for you each week! (Note: click on each tip to read an expanded blog post.)

Today’s installment: kick-a** tracking, metrics, and analytics tips. Enjoy!

Tip: A Facebook “click” isn’t measured the same way as a search “click.”
