Ideas on how to monetize an information site

I recently launched https://www.whatcard.sg/ which allows users to find the best credit card for the maximum rewards before making a spend. Currently we have two monetization strategy:

1. Joined a affiliate program where we get paid when a user clicks on a credit card link to the affiliate's site and then click on the apply now button.

2. A free credit card consultation service where we get paid an affiliate fee when the user signs up for certain credit cards through us.

I was wondering if the community here might have some more monetization ideas that we can consider. Thank you in advance :) :)
