The core problem with lead-generation sites is incentive, not geography. HomeLight and FastExpert are paid referral networks, so an agent's placement often reflects a referral fee arrangement rather than verified local sales, which is the opposite of what a buyer or seller needs when choosing who represents them.
A general review site like Yelp captures customer service impressions, which have some value, but it does not verify whether a reviewer's transaction actually closed or who the licensed brokerage was. The Saskatchewan Real Estate Commission is the body that actually licenses and disciplines agents in this province, in a market the Saskatchewan REALTORS Association reports at 1.63 months of supply.
