Google Analytics is an incredibly powerful tool for your website and business. It can show you exactly where things are going right, and going wrong, helping you to identify problem areas and focus on the things that are working. It can help you answer questions like "what marketing efforts are generating the most revenue?" and "which pages on my website are losing visitors?". Unfortunately very few people have Google Analytics setup properly and are often making decisions based on "dirty data". I'll make sure your Google Analytics is setup correctly and is configured and reporting accurately on your business goals.
Nothing! If you don't already have Google Analytics setup I'll set that up for you as well.
