What should I look for?

Look for stages with unusually high drop-off relative to the rest of the funnel. These can indicate issues with traffic quality, landing pages, lead qualification, checkout processes or sales follow-up.

Important:A high drop-off is not automatically bad. Different funnel stages have naturally different conversion expectations depending on traffic source, business model and qualification criteria.
