But how can you show how proactive you have been in your quarterly performance review without testing out various user funnel strategies, optimizing conversion rates and paying consultants for A/B tests?
You mention tactics. Instead, focus on metrics trends. Optimizing the customer experience may include the tactics you've mentioned, but if you walk into a review and show that your customers are happier (net promoter score, or clips from user testing, for example), conversion rates are up, and online revenues are up... that would be pretty darn good evidence of a job well done.
