As of my last knowledge update in September 2021, Moz, the company behind Domain Authority (DA), did not provide a direct tool for checking the historical DA of a website for free. However, you could monitor the changes in your website's DA over time by following these steps:

1. Moz Link Explorer (Paid): Moz offers a tool called "Link Explorer" that provides historical DA data. With a paid subscription, you can access historical DA trends for any website. Here's how you can use it:

   • Go to Moz's Link Explorer.
   • Enter the URL of the website you want to check.
   • In the left sidebar, click on "Inbound Links."
   • Scroll down, and you'll see a graph that displays the historical DA data.

2. Using Free Tools (Limited): While you won't get detailed historical data, some free tools can provide a rough idea of a website's DA changes over time. You can take periodic snapshots of your DA using Moz's free DA checker or other third-party tools. However, these tools usually only provide the current DA, not historical data.

3. Manual Tracking (Labor-Intensive): This method involves manually recording your website's DA at regular intervals using Moz's DA checker. While it's not as efficient as using automated tools, it allows you to create your own historical record.

Keep in mind that tracking DA history is useful for understanding trends, but it's more important to focus on improving your website's overall authority and SEO performance than obsessing over DA fluctuations. Moz periodically updates its algorithms, which can affect DA scores, so small fluctuations are normal.

Please note that Moz might have introduced new features or tools since my last update in September 2021. I recommend visiting the Moz website or contacting their support for the most current information on checking DA history.

Hello,
In my opinion, more important than the domain age factor is the indexing time in Google, which Google has recently placed great emphasis on. You can click on the three dots next to each website link and find out the time of the first index of the domain in Google.

Thank you.

To improve your Domain Authority (DA) in Moz, you'll need to focus on building high-quality backlinks, improving on-page SEO, and enhancing your overall website's authority. Moz's Domain Authority metric is a proprietary score that predicts how well a website will rank on search engine results pages (SERPs). Here are steps to help you increase your DA:

1. Create High-Quality Content: Develop valuable, informative, and engaging content that attracts readers and other websites. High-quality content naturally attracts backlinks, which can positively impact your DA.

2. On-Page SEO Optimization: Optimize your website's on-page elements, including meta tags, header tags, image alt text, and keyword usage. Ensure that your content is structured well and provides a good user experience.

3. Internal Linking: Implement a sound internal linking strategy by connecting related content within your website. This not only helps with user navigation but also spreads authority across your site.

4. Mobile Optimization: Make sure your website is mobile-friendly. Google and Moz consider mobile-friendliness when calculating DA and search rankings.

5. Technical SEO: Address technical issues on your website, such as broken links, slow page loading times, and crawl errors. A well-optimized website performs better in search results.

6. Quality Backlinks: Focus on acquiring high-quality backlinks from reputable websites in your industry. Quality is more important than quantity when it comes to backlinks. Building relationships with other webmasters and creating shareable content can help with this.

7. Guest Posting: Write guest posts for authoritative websites in your niche. This can help you gain exposure and build valuable backlinks.

8. Social Media Presence: Actively engage with your audience on social media platforms. While social signals may not have a direct impact on DA, they can indirectly help drive traffic and awareness, which can lead to more backlinks.

9. Monitor Your DA: Keep an eye on your DA score in Moz's Link Explorer. This will help you gauge the effectiveness of your efforts and identify areas that need improvement.

10. Patience and Consistency: Improving your DA takes time. Be patient and stay consistent with your SEO efforts. Regularly update and refresh your content to maintain its relevance.

11. Avoid Black-Hat SEO Tactics: Stay away from unethical SEO practices like buying links or engaging in link schemes. These can lead to penalties from search engines and hurt your DA.

12. Competitor Analysis: Analyze your competitors with higher DAs. Understand their strategies and see if you can adopt similar tactics, but remember to focus on providing unique value to your audience.

Remember that DA is just one of many factors that influence your website's search engine ranking. It's also important to monitor your overall SEO performance, including keyword rankings, organic traffic, and user engagement, to ensure you're making progress in the right direction.
