Most insurance keywords look commercial on the surface. Someone typing renters coverage near them could be ready to buy, or they could already have a policy and need to file a claim after a pipe burst. Carrier brand searches mix prospects with policyholders who want a login page. An account that treats every one of those searches the same fills your phone line with calls your producers cannot turn into premium.
Captive and independent agents face different auctions
A captive agent usually works within the rules a single carrier sets for its name and logo in ads, and often competes against that same carrier's national campaigns. An independent agent can talk about many carriers but has to be careful using their trademarks in ad copy. Both share the same auction with direct writers and comparison sites that bid aggressively on broad terms, so a smaller shop wins by being narrower: specific lines, specific counties, specific hours when someone answers.
Lines of business need their own campaigns
Personal auto, homeowners, commercial liability, life and Medicare supplements attract different buyers, different urgency and different compliance wording. Mixing them in one campaign hides which line is paying its way and blurs the message on the landing page.
