Link Checker Report Analysis And Discussion

Hey guys, let's dive into this link checker report! We've got a lot to unpack, so let's get started. This report gives us a comprehensive overview of the status of links across our project, helping us identify and fix any broken or problematic links. Keeping our links healthy is super important for user experience and SEO, so let's see what we've got.

Understanding the Summary

First off, the summary table is the place to begin. In this section, let’s break down what each status means and what actions we might need to take. It gives us a bird's-eye view of the overall link health. Let's break down what each status means:

• 🔍 Total: This is the total number of links checked, giving us a sense of the scope of the report. In this case, a whopping 15405 links were checked! That's a lot of links!
• ✅ Successful: These are the links that are working perfectly fine. A successful link means it leads to the correct destination without any issues. We have 6394 successful links, which is great, but there's still room for improvement.
• ⏳ Timeouts: Timeouts mean the link took too long to respond. This could be due to a slow server or a temporary network issue. It's essential to monitor these, as persistent timeouts can indicate a more significant problem. We've got 34 timeouts, which isn't too bad, but we should keep an eye on them.
• 🔀 Redirected: Redirected links are those that have been moved to a new URL. While redirects are normal, it’s a good practice to update the links to point directly to the new URL to improve performance and user experience. With 838 redirects, it might be worth updating some of these to the direct URLs.
• 👻 Excluded: These are links that were intentionally excluded from the check, often because they point to resources that aren't meant to be publicly accessible or are intentionally left broken for specific reasons (like placeholders). We have 3769 excluded links, so we should make sure these exclusions are intentional and correct.
• ❓ Unknown: This status indicates that the link checker couldn't determine the status of the link. This is rare, as the report indicates there are 0 unknown links. 🤷
• 🚫 Errors: Errors are the most critical issues, indicating broken links or other problems that prevent the link from working. With 4343 errors, this is a significant area we need to address. We'll need to investigate these errors to understand why they're happening and fix them.
• ⛔ Unsupported: These are links that use protocols or formats that the link checker doesn't support. There are 27 unsupported links. While this number is relatively small, we should check if these links are essential and find alternative ways to link to the resources, or update the checker to support them.

Overall, while we have a good number of successful links, the high number of errors is concerning. Let's dig deeper into the error breakdown to identify the root causes.

Errors per Input File

Now, let's zoom in on the errors. The report breaks down errors by the input file, which helps us pinpoint where the issues are originating. This is where we get granular and start looking at specific files.

Errors in 0-First-Steps-Lab.md

This file has a bunch of errors, let's analyze what's going on here. It looks like we have a mix of file not found errors and a rejected status code.

• [ERROR] <file:///home/runner/work/Y4xb1xG5YjY/Y4xb1xG5YjY/images/image-20191008154755641-0542475.png> | Cannot find file: File not found. Check if file exists and path is correct

  ... (and similar errors for other images)

  These errors indicate that the image files are missing from the specified path. This could be due to several reasons:

  • The images were never uploaded.
  • The file paths in the Markdown file are incorrect.
  • The images were moved or deleted.

  To fix these, we need to:

  1. Verify that the images exist in the correct directory.
  2. Update the file paths in the Markdown to match the actual location of the images.
  3. Re-upload the images if they are missing.

• [404] https://www.okd.io/download.html | Rejected status code (this depends on your "accept" configuration): Not Found

  This error means the link to https://www.okd.io/download.html is broken, returning a 404 Not Found error. This indicates that the page either doesn't exist or has been moved.

  To resolve this, we should:

  1. Visit the URL to confirm it's broken.
  2. Search for the correct URL or an updated resource on the okd.io website.
  3. Update the link in the Markdown file.
  4. If the resource is no longer available, consider removing the link or finding an alternative resource.
