Yes, you definitely should. It’s very important to know what you’re doing. Not just your solo ad, you should track all of your marketing efforts. Be it solo ads, free traffic sources or PPC. You need to understand your numbers to stay profitable. I use and recommend ClickMagick, which also happens to be my favorite link tracking service. Other than tracking your marketing campaigns, you also need an autoresponder service and a good web hosting account. You’d be driving traffic to your funnel so you want a reliable web hosting service. You can find tools that I use and recommend here.
