Link seller sites often engage in black hat SEO tactics, such as buying and selling links, which violate search engine guidelines. These links are often low quality and irrelevant, and search engines like Google can penalize websites that engage in these practices. It's important to focus on building high-quality, relevant backlinks through organic means, such as creating valuable content and engaging in outreach to reputable websites in your industry. **

This way, the animation will only play when the element is visible to the user, providing a better user experience and performance. **
