Tax questions are read by thousands and answered by almost no firm. What can be claimed, how a dividend differs from a salary, what happens when a threshold is crossed: each is a page, and each brings somebody who realises they are out of their depth.
Before choosing a firm, people decide whether to hire one at all. Comparing the fee against the time and the risk of doing it alone is the argument that has to be won first, and it is winnable with plain arithmetic.
Events create urgency in a way routine work never does. Selling a property, passing a registration threshold, receiving an inheritance or closing a company are moments where a wrong step is expensive and advice is bought immediately.
Most clients arrive on a recommendation and then check. The site's job in that moment is not to persuade a stranger but to confirm what a friend already said, which means real names, real credentials and no marketing language.
