thanks in advanced my friends..

My suggestion would be, Use backlinks related to your website's topic for better results, and get links from various sources to make your website stronger, even if it's in a different niche like gambling

Try to acquire links from high-quality sources, such as niche-relevant, high-DR traffic sites. Promote your content on social media and other online platforms.

web 2.0 is best for you
