Small drops in Domain Authority are normal. See what affects your score, why it fluctuates, and how to build strong backlinks to improve it.
It’s totally normal for Domain Authority (DA) to fluctuate a few points over time, so a small drop isn’t usually anything to worry about. DA is a score that estimates how strong your website is compared to others, and it can change for a variety of reasons.
Why Your DA Might Be Dropping
- Moz Updated Its Algorithm – Since DA is calculated by Moz, any updates to how they measure authority can cause shifts in your score.
- You Lost or Devalued Backlinks – If websites linking to you remove their links, or if some backlinks lose value, your DA may dip.
- Competitors Are Growing Faster – If other sites in your industry are earning strong backlinks, your DA might drop in comparison.
- Your Backlink Profile Hasn’t Grown – If you haven’t added new quality backlinks in a while, your score may naturally decline.
- Spammy Backlinks Were Removed – If you cleaned up bad backlinks or they were deindexed, your DA might adjust before stabilizing.
