The Most Expensive Keywords in Online Advertising

WordStream, an online marketing company, analyzed the most expensive keyword categories for online advertising and found that keywords related to Insurance, Loans, Mortgage, Attorneys and Credit were the most expensive with advertising costs ranging between $55-$45 per click.

In the tech domain, the high-paying keywords are around web hosting, conference call services, CRM / help-desk software and data recovery software.

The advertising rates for such niches are so high for two reasons – there’s plenty of competition among advertisers so they have to bid higher to outbid the other and second, the return after winning a customer is extremely high.
