To check the Domain Authority (DA) history of a website, you can use the following methods:
Moz’s Link Explorer: Visit Moz’s Link Explorer, enter the website URL, and view its DA score. Moz provides historical data on DA through its tools if you have a Moz Pro account.
SEO Tools with Historical Data: Use SEO tools like Ahrefs or SEMrush, which offer historical data tracking for domain metrics, including DA. Search for the domain in these tools and check their historical data sections.
Wayback Machine: Visit the Wayback Machine and look at archived versions of the site. While it won’t show DA directly, you can review historical content and compare it with current DA data from SEO tools.
Google Search Console: Although it doesn't provide DA history, you can analyze historical performance and backlinks in Google Search Console, which can offer context for changes in DA.
