Yes, a good Marketing Analytics Service is able to measure the performance of a marketing campaign with actual data rather than assumptions. It can provide insights on the channels that are working to generate leads, content that is resonating, and where to allocate marketing dollars to improve. These lessons learned can be used to enhance future campaigns and minimize wasted spend. I stumbled across Datalance as I was reading around analytics companies and they seem to be supportive of businesses that wish to make informed decisions via analytics analysis and not guesswork.
