Dealing with 4XX errors, specifically broken links, is important for maintaining a healthy and user-friendly website. Here are some recommendations for handling such situations:

Assess the Importance of the Pages:

Determine the importance and relevance of the pages that are generating 4XX errors. If the content is still valuable, consider updating and reactivating the page.
Content Removal or Update:

If the content is outdated or no longer relevant, you may want to remove it. Alternatively, consider updating the content to make it current and useful.
Redirecting to Relevant Pages:

If the content is no longer available, but the page has external links or is indexed in search engines, consider setting up 301 redirects to relevant and existing pages on your website. This will help maintain SEO value and provide a seamless experience for users and search engines.
Custom 404 Page:

Create a custom 404 error page that provides users with helpful information, such as a search bar, popular pages, or a link to your homepage. This ensures that users who encounter broken links have options for navigation.
Review and Update Sitemap:

Ensure that your website's XML sitemap is up-to-date. This helps search engines discover and index the latest content on your site.
Monitor Webmaster Tools:

Use tools like Google Search Console to identify and monitor 404 errors. This will help you stay informed about issues and address them promptly.
Communicate Changes to Users:

If a page is being redirected or removed, it's good practice to communicate this to your users through on-page messages or announcements. This helps manage expectations and reduces confusion.
Periodic Content Audits:

Conduct regular content audits to identify and address outdated or irrelevant content. This proactive approach can help prevent the accumulation of broken links over time.
In your specific case, if you decide to reactivate a page and redirect it to your main website , ensure that the redirection is relevant and adds value to users. Additionally, check for any potential impact on SEO and update internal links to reflect the changes.

Remember, the goal is to provide a positive user experience, maintain SEO integrity, and keep your website content up-to-date.

The crawl depth reported by tools like Moz Pro is determined by the level of clicks it takes to reach a particular page from the homepage or root domain. It's not solely based on whether the page is HTTP or HTTPS.

In your scenario, if Moz Pro is reporting that the HTTP version (http://www.example-domain.com) has a crawl depth of 0, it means that this page is directly accessible from the root domain. On the other hand, if the HTTPS version (https://www.example-domain.com) is reported as having a crawl depth of 2, it implies that it takes two clicks (or two levels deep) from the homepage to reach this particular HTTPS page.

There could be various reasons for such a situation, such as the site structure, internal linking, or redirects. It's not uncommon for websites to have different versions (HTTP and HTTPS) of their pages, and the crawler may follow links or redirects differently, leading to variations in crawl depth.

To further investigate, you may want to examine your site's internal linking structure, make sure that there are no unexpected redirects or canonicalization issues, and ensure that your preferred version (HTTPS in this case) is correctly configured and prioritized in your website settings and sitemap. Additionally, Moz Pro may provide more detailed insights into the specific reasons for the reported crawl depth if you review the crawl report or log files.

Differences in the backlink data provided by different tools like Moz and Ahrefs can be attributed to several factors. Each tool uses its own web crawlers and algorithms to gather and process data, leading to variations in the results. Here are some reasons why you might see differences in backlink data between Moz and Ahrefs:

Crawling Frequency and Depth:

Each tool has its own crawling schedule and depth. Some tools may crawl the web more frequently or deeply than others, leading to variations in the backlinks they discover.
Crawling Sources:

Tools may use different sources for crawling the web. They might have different partnerships, access to different websites, or utilize unique methods to discover backlinks.
Data Processing Algorithms:

The algorithms used by each tool to process and filter backlink data may differ. This can result in variations in how they identify and report backlinks.
Quality and Accuracy of Data:

The quality and accuracy of the data collection process play a crucial role. Some tools may have more sophisticated algorithms or better data filtering mechanisms, leading to more accurate results.
Index Updates:

Tools update their backlink indexes at different intervals. Ahrefs and Moz may not update their indexes simultaneously, causing differences in the reported backlink data.
Blocked or Restricted Access:

Some websites may block certain web crawlers or limit access to specific user agents. If one tool is blocked or restricted, it may miss certain backlinks that another tool can access.
Historical Data Differences:

Historical data, especially for older backlinks, might not be as comprehensive or up-to-date in one tool compared to another.
It's common for discrepancies to exist between different SEO tools, and it's generally advisable to use multiple tools to cross-verify and get a more comprehensive view of your backlink profile. If you notice significant differences, it could be worthwhile to investigate the specific reasons behind those variations or consult the support/documentation of each tool for more insights.

@RichardNM If the domain has changed ownership and the new content or purpose is significantly different from the previous one, it may take some time for search engines to reevaluate and reindex the website. Here are some steps you can take to improve the chances of getting the site re-indexed:

Update and Optimize Content:

Ensure that the website content is relevant to the new industry or business.
Optimize on-page elements such as title tags, meta descriptions, and headers with keywords related to the new business.
Submit a Sitemap:

Create an XML sitemap for the website that includes all the relevant pages. Submit the sitemap to major search engines like Google through their respective webmaster tools.
Verify Ownership in Search Console:

Verify ownership of the domain in Google Search Console and other search engine webmaster tools. This allows you to monitor the indexing status, identify issues, and receive notifications from search engines.
Check for Penalties:

Make sure the domain hasn’t been penalized by search engines. Check for manual actions in Google Search Console.
Build Quality Backlinks:

Acquire high-quality backlinks from reputable websites in the new industry. This can help signal to search engines that the website is trustworthy and relevant.
Social Media Presence:

Promote the website on social media platforms. This can contribute to increased visibility and may help search engines discover and index the site.
Fetch as Google:

Use the "Fetch as Google" tool in Google Search Console to submit specific URLs for indexing.
Check for Technical Issues:

Ensure there are no technical issues hindering the indexing process. Check for crawl errors, broken links, and proper redirections.
Monitor Indexing Status:

Regularly check the indexing status in Google Search Console to see if there are any issues or improvements over time.
Patience:

Indexing can take time, especially for a domain that has changed ownership and content. Be patient and continue to focus on creating high-quality, relevant content.
Remember that SEO is an ongoing process, and improvements in search visibility may take time. Consistently monitoring and optimizing your website will contribute to better long-term results.
