The site is a verification step more often than a discovery one
Most visitors already know who you are and are checking whether you are what they were told.
The common sequence is a call, an email or a referral, followed by somebody looking the firm up. They are answering a short list of questions: is this real, who are these people, do they actually work in my market, and have they done this before.
That should determine what is easy to find. Who the brokers are and what they cover, what the firm actually does, where it operates, and evidence of activity in the relevant submarket.
It also means the home page has a narrower job than a consumer site's. It is not persuading a stranger from nothing. It is confirming an impression somebody already formed on a phone call.
The failure mode is a site that reads as generic. A firm whose home page could describe any brokerage in any city gives a checker nothing, and the check ends ambiguously.
Currency matters disproportionately here. A site whose most recent anything is two years old suggests a firm that is not busy, which is the opposite of the impression the check is meant to produce.
