The date is the real enquiry. Somebody searching 14 September wants to know whether it is free, and a page with no availability loses that contact.
The occasion governs everything else. Weddings, company parties, balls and clubs are four professions with the same gear and opposite expectations.
Musical style is searched explicitly. Typing «techno DJ» rules out a compere, and typing «wedding party DJ» wants precisely the opposite.
The rig belongs on the page, because the venue asks about it. Sound limiters, power supply and set-up time are the venue's questions, not the host's.
The fee is looked up before the call. Naming a range by hours and travel filters out the enquiries that would never have booked anyway.
The territory is narrower than it looks. Travel, an overnight stay and driving home after three in the morning limit the radius, and that deserves writing down.
A reference replaces the argument entirely. A video of a room still full at three in the morning convinces more than any description, and people genuinely search for it.
How much hosting is included separates offers more than the playlist does. Announcing, introducing the couple and holding the running order sells something other than a sound system.
Extras decide the booking. Lighting, haze, a photo booth and a second room are the searches that turn a comparison into a contract.
