I like that we can track our campaign data in one place using Google Analytics dashboard or via API calls to see how they perform over time.
We have only used this tool as an analytics platform so far but if there is anything i dislike atm its not really something specific with chain link itself - just everything else around us right now (COVID-19). But overall very happy customer experience once onboarded by their team of experts who guide through every step from planning phase till implementation/deployment stage. Tracking website traffic sources & campaigns performance which ultimately helps me improve my online content strategy moving forward.
