When I started my website, https://webylinks.com/, intiallyI was heavily invested in purchasing hundreds of backlinks. However, instead of rank improvement, it dropped from 16 to 15 DA. So, I shifted my strategy to earning quality backlinks through white hat methods. I have also shared my experience on this journey here https://webylinks.com/how-to-create-quality-backlinks/. I strongly recommend to earn them through proper content, make strategies and engage with niche relevent websites.
