Engage your potential customers with web design that is up to date and exciting. Use cool features like parallax scrolling and make sure the user experience is on point. If your website looks clean and is easy to navigate, you will be able to build trust with potential customers. If customers land on your site and don’t understand how to navigate or can’t find what they’re looking for, you have just lost a sale.
But I think you have missed one point “Adding offers from cpa networks related to your niche. They have higher payouts and works pretty well with banner ads.”. Once I had a finance related site and one of the post ranking well was on credit score. So i added credit score checking offer on that post and surprisingly making 10-15 folds what i was making from google adsense every day.
