As a general rule of doing business online if you can track where your traffic is coming from always do it.
Back in the day when I first started out I never use to bother with tracking where my traffic was coming. It wasn’t until I spent my first 1K on 4 different traffic sources at the same time that I realized there was no way to tell which source was giving me the most traffic.
When you track your traffic you’ll be able to tell what source of marketing works best and when you figure that out you’ll be able to invest your marketing budget much more wisely. Don’t make the same mistake I did back then – always track.
