Google doesn't like paid back links just because google thinks you are doing wrong with your site. Your site doesn't have quality contents and something worthy on it. If your site has good and quality content, your site has innovation and creativity then you doesn't need to get paid backinks. Just do good quality work for your site. For example, Lamborghini/Rolls Royce/etc. don't need more to advertise for his car model. Just because we all know the features and luxury. But Renalut, Suzuki, Toyota, etc. need advertisement for their car model. Why? They also have quality and luxury but Why they need to promote? If you have answer then you can easily find out why google hates paid link building.
