Internet Marketing ROI or return on investment can be a very strange thing to analyze because it is a very slow planted seed that takes time to sprout. Content you distribute today could bring in traffic 6 months from now which is why trying to analyze your internet marketing ROI right out of the gates can be very difficult at times. There are however ways you can track certain activities that could allow you to make an educated guess on how well things are working for you.
Analyze Your Analytics
If you conduct a variety of online marketing efforts on a weekly basis get into your analytics account a few times per/week to see how things are working. If you are active in a location that never delivers any traffic it might make sense to eventually look for somewhere else to hangout.

Website Elements
Sometimes it is difficult to track conversions so try leaving a mandatory field on either your shopping cart or your lead form asking people how they heard of you. As long as you don’t make the form too complicated it will allow you to understand how people are finding you.
PPC Tracking
If you are doing PPC marketing online you could very easily set up tracking to see how well it is working for you. The steps require setting up a “thank you” page after the consumer makes their purchase and piece of tracking code on the thank you page will trigger a conversion allowing you track all your ad dollars spent and how well they are working for you.
Simply Asking
If you take all your sales and leads through an incoming call you simply need to start asking how people found you. Some will not really remember but many will and they will be glad to tell you how they bumped into your website.
Internet marketing ROI can often times be difficult to isolate for every little thing you do online but it is important to try and analyze where you traffic is coming from. If you are not equipped to set up all the technologies to track every little piece of movement start by looking at your analytics information so you can see how people are interacting with your website.
