Forms are important for websites but can reduce conversions if not optimized. Google Analytics can track form completion rates and identify dropout points through the goal funnel report. Key events like form starts, field errors, and completions should be tracked to find issues preventing submissions. Analyzing this data can reveal problems like difficult fields or missing information, which can then be addressed through changes like breaking long forms into sections, clarifying benefits, or adding help text to fields. Tracking field-level errors specifically shows where visitors encounter problems that cause abandonment, helping to optimize the form and minimize wasted opportunities.
