People look for a valuer with a specific purpose: "property valuation near me", "probate valuation", "insurance valuation in your city". SEO for valuers is what keeps you visible all year on those searches — the ready-to-instruct ones — instead of losing the instruction to whoever ranked first on Google.
Almost nobody searches for a valuer out of curiosity: there is a divorce, an inheritance, a mortgage or a court deadline behind it. The purpose decides everything — which register you must be on, what the report has to contain and who will accept it — so a page per purpose is worth more than any presentation of the firm.
Your purposes and asset types are the search terms that matter. Ranking for "probate valuation", "matrimonial valuation", "machinery valuation" or "insurance reinstatement valuation" brings the clients who need precisely the report you produce. We turn each of those questions into its own page, so Google sends you instructions, not just clicks.
What gets asked of an assistant is «is a valuation valid for probate» or «how long is a mortgage valuation good for». Those answers are regulated and specific, which is exactly why a page that gets them right is cited — nobody else bothers to be precise.
