Domain authority (DA) changes gradually and depends on several factors like backlink quality, quantity, and competition. If your DA hasn’t changed, it’s likely because your backlink profile hasn’t significantly improved or because competitors are building stronger links. Focus on acquiring high-quality, relevant backlinks, optimizing on-page SEO, and creating valuable content to encourage organic link building. It takes time, so consistency is key!

You can check a domain's age by using tools like Whois Lookup or Domain Age Checker available online. Simply enter the domain name, and these tools will show the registration date and other details. Alternatively, you can visit the website's Whois database to find the domain's creation date. This will give you a clear idea of how long the domain has been active.
