What people actually ask
Searching for each of 3,101 law firms by name returned, alongside the results, the questions Google reports people also ask. There were 16,284 of them. Grouped by subject rather than wording, this is what somebody looking for a lawyer in England and Wales is unsure about.
The count is the number of different firms whose search results raised the question, not how many people asked it. A question that appears against 600 different firms is a question about the profession; one that appears against a single firm is a question about that firm. Google's own panels are not reproduced here — only the count, and our answer.
