For the second consecutive year, GEICO earned top honors among car insurance companies for its ability to create loyal customers in the 2008 Brand Keys Customer Loyalty Engagement Index. GEICO led auto insurers, ranking ahead of State Farm, Allstate, Nationwide and Progressive.

The annual study examines consumer relationships with 382 brands in 57 categories to determine category drivers that create loyal customers and increase profits. Brand Keys Inc., a marketing research company, conducts the study.

According to the study, the brand whose drivers come closest to meeting or exceeding those of the category ideal is always the one whose customers will exhibit the highest levels of engagement and loyalty over the next 12 to 18 months.
