Hello,

I understand your concern about the drop in your Domain Authority (DA) on your website. Fluctuations in DA can be frustrating, but there are a few factors to consider:

1. Different Algorithms: Moz, Google Webmaster Tools, and Ahrefs all have their own algorithms and methods for calculating domain authority and tracking backlinks. These algorithms can sometimes produce different results.

2. Update Delays: Updates to DA might not be in real-time. Moz updates its DA calculations periodically, so changes in your backlink profile might not be immediately reflected.

3. Quality vs. Quantity: It's not just about the number of domains linking to your site; the quality of those links matters too. Google and Moz evaluate links based on various factors, including relevance, authority of linking sites, and the context of the link.

4. Link Quality: High DA doesn't always guarantee a positive impact on your site's DA. If some of the new links are from low-quality or spammy sites, they might negatively affect your DA.

5. Competitor Changes: Changes in the backlink profiles of your competitors can also influence your DA.

6. Technical Issues: If Moz isn't detecting certain backlinks, there might be technical reasons behind it, such as blocked crawlers, nofollow attributes, or dynamic content.

7. Content Quality: While DA is influenced by backlinks, the overall quality and relevance of your content also matter. Google and other search engines consider various factors beyond just backlinks.

Regarding your question about Moz crawling all domains fairly, Moz's crawler aims to be comprehensive, but like any other crawler, it might not capture every single link. The data provided by Moz is an estimate based on their crawl, and it might not perfectly match other tools like Ahrefs.

If you're seeing positive results in Google Webmaster Tools and Ahrefs, it's a good sign that your site is gaining recognition. Keep focusing on high-quality content creation, ethical link-building practices, and providing value to your audience. Over time, these efforts should help improve both your domain authority and your site's overall performance.

Remember that SEO is a long-term endeavor, and it's normal to experience fluctuations. If you're still concerned, you might consider seeking advice from SEO professionals who can provide more tailored guidance based on the specifics of your situation.

To check the age of a domain, you can use various online tools and domain lookup services. One of the most popular methods is to use a domain age checker website. Here's a step-by-step guide on how to check the domain age:

1. Go to a domain age checker website: There are several websites available that offer domain age lookup services. One such website is "Whois.net," but you can also use other services like "DomainTools," "Whois.com," or "ICANN WHOIS."

2. Enter the domain name: Once you are on the domain age checker website, you'll find a search bar. Enter the domain name (e.g., example.com) for which you want to check the age.

3. Perform the search: After entering the domain name, click on the "Search" button or press the Enter key.

4. View the results: The domain age checker tool will provide you with the information about the domain, including its creation date or registration date. The creation date is the date when the domain was registered and became active.

Please note that some domain age checker websites may require you to complete a CAPTCHA or other verification steps to prevent misuse of their services.

Alternatively, you can perform a manual check using the WHOIS database. Here's how:

1. Open your web browser and go to the "whois" website of your choice, like "whois.icann.org."

2. Enter the domain name (InstahGb) in the search box and press Enter.

3. Look for the "Creation Date" or "Domain Registration Date" in the results. This date will indicate the age of the domain.

Remember that some domain registrars offer privacy protection services, which might hide certain domain registration information in the WHOIS database. In such cases, you might not be able to find the exact creation date of the domain.

Using either of these methods, you can quickly determine the age of a domain and gain valuable insights into its history.
