Thanks Cody, I understand some of the companies will nofollow, but many of the insurance companies dofollow. Safeco, in particular, seems to be an easily indexed link I see for many brokers.
My understanding is that these "agent locator" type pages are usually dynamically generated using many search variables (eg zipcode, city, type of insurance, etc) which means the chances of ever getting indexed could be pretty slim. Is it mainly how the page is designed and how often the site is crawled? I suppose eventually it'll get indexed, just wondering if anyone had insights on improving the situation.
It's not isolated to insurance agents, any particular niche that gets links from vendors they buy from would be similar. For example a pet store might get links from dog good companies.
I agree that it shouldn't be the only link building strategy, but it's an easy start that many businesses don't do.
