Disavowing spammy backlinks in Google Search Console is a great step in maintaining a healthy backlink profile. However, it's essential to understand that disavowing links doesn't directly impact Moz DA (Domain Authority).
Moz DA is a metric calculated by Moz, an independent SEO tool provider. It's based on their own algorithm, which assesses various link equity and ranking factors.
Here are a few possible reasons why your Moz DA might not have increased despite disavowing spammy backlinks:
1. Disavow file processing time: Google needs time to process the disavow file. It may take several weeks or even months for the changes to be reflected in Google's index.
2. Moz's data update cycle: Moz updates its link index and DA scores periodically. It may take some time for Moz to recrawl and reindex your site, reflecting the changes in your backlink profile.
3. Link equity redistribution: When you disavow spammy links, the link equity associated with those links is not immediately redistributed to other links. This process can take time, and Moz may not immediately reflect these changes in their DA score.
4. Other ranking factors: Moz DA is influenced by various factors, including link equity, content quality, and technical SEO. Improving your backlink profile is just one aspect of SEO. Focus on creating high-quality content, optimizing your site's structure, and improving user experience to increase your Moz DA.
5. DA score fluctuations: Moz DA scores can fluctuate due to various reasons, such as changes in Moz's algorithm, updates in their link index, or shifts in your site's ranking factors.
To better understand the impact of disavowing spammy links on your Moz DA, monitor your site's performance using tools like Google Search Console, Google Analytics, and Moz's own tools, such as Moz Pro or Moz Link Explorer. Focus on creating high-quality content, improving your site's technical SEO, and building a strong, authoritative backlink profile.
