Several factors can contribute to a decrease in DA:
Loss of Quality Backlinks: If your website loses backlinks from high-authority and reputable websites, your DA can decline. Backlinks are a significant factor in determining a website's authority.
Spammy Backlinks: If your website gains low-quality or spammy backlinks, this can negatively impact your DA. It's essential to regularly monitor your backlink profile and disavow harmful links.
Algorithm Updates: Search engines like Google frequently update their ranking algorithms. If your website's content or structure does not align with these updates, it can lead to a decline in rankings and, subsequently, a lower DA.
Content Quality: The quality and relevance of your website's content play a crucial role in its authority. If the quality of your content deteriorates, it can affect user engagement and, indirectly, your DA.
Technical Issues: Issues with website speed, mobile-friendliness, or security can lead to lower rankings and a reduced DA.
I was also facing the same issue with the eDPI Calculator, but now its fine. To address a decrease in DA, consider the following steps:
Audit Backlinks: Review your backlink profile to identify any lost or spammy backlinks. Disavow low-quality links using Google's Disavow Tool.
Content Audit: Assess the quality and relevance of your website's content. Make improvements where necessary to enhance the user experience.
Technical SEO: Ensure that your website is technically sound. Address any issues related to site speed, mobile optimization, and security.
Stay Informed: Keep up to date with search engine algorithm updates and industry best practices to adapt your SEO strategy accordingly.
Build High-Quality Backlinks: Focus on acquiring high-quality, relevant backlinks through outreach, content marketing, and guest posting.
Patience: Recovering from a decrease in DA can take time. Continue to implement SEO best practices and monitor your progress regularly.
I hope you got my points.
