Advantages of Goal Setup on Google Analytics

Once you have all possible goals setup then it’s easy to see how converting visitors are finding your website or which types of visitors are the ones which convert:

If you are paying for traffic towards a website you could figure out a cost-per-lead for example or a cost-per-revenue report.
If you are generating leads through social channels then you could see which channel (Facebook, Twitter, Email Marketing, etc.) is bringing in the most valuable leads.
If you have two or more popular landing pages then you could measure which one generates more goals on average and promote it further.

The advantages of goal tracking are tenfold; no longer will you be in the dark about how a website is performing or how you brought any valuable visitors towards the website. You can then act on the positive or negative goal data to improve your website or external marketing.
