The visitor arrives with a dashboard open. Somebody searching about a falling conversion rate has the figure in front of them, and an explanation of the usual causes reaches them at the moment they are looking for help.
Abandonment is where the money visibly leaks. People who can see exactly where users disappear look for checkout and form drop-off, and that specificity makes the enquiry easy to qualify.
Benchmarks are searched constantly and answered lazily. What a good conversion rate looks like for a given sector is a question with no single answer, and treating it seriously is unusual enough to be remembered.
In-house teams search for method. Test design, sample size and how long to run an experiment come from people who intend to do it themselves and frequently end up needing a second opinion.
