"Errors using inadequate data are much less than those using no data at all." - Charles Babbage.
Website analysis is the practice of testing and analyzing a website's performance in relation to SEO, speed, competition, and traffic.
Any site can benefit from some form of website analysis if the results are then used to improve it—for example, by reducing page size to increase overall speed or optimizing a landing page with lots of traffic for more conversions.
Website analytics provide insights and data that can be used to create a better user experience for website visitors.
With website analytics, you can also accurately track the effectiveness of your online marketing campaigns to help inform future efforts.
