Why Does Moz Only Index Some Links?
From my experience, Moz might only index some links on a site due to several factors such as crawl budget, site structure, or content quality. I recently dealt with a similar issue on themepcobill.com.

Here’s how I approached and solved the problem:

Crawl Budget Optimization: Moz, like other search engines, allocates a specific crawl budget to each site. Ensuring that the most important pages are easily accessible and linked from the homepage helps in better indexing. For my site, I audited the internal linking structure to ensure that important pages weren't buried deep within the site.

Fixing Technical Issues: I used tools like Google Search Console and Moz’s Site Crawl to identify and fix technical issues such as broken links, duplicate content, and slow loading pages. Ensuring that the site's XML sitemap was up-to-date and submitted to Moz also helped improve crawl efficiency.

Quality Content: High-quality, unique content tends to get indexed more reliably. I reviewed the content on Mepco Bill Page to ensure it was engaging and provided value to visitors. Updating old content and adding new, relevant information also made a significant difference.

Backlink Profile: Having a strong backlink profile helps in better indexing. I worked on acquiring high-quality backlinks, which in turn improved its overall visibility and indexing rates on Moz.

By focusing on these key areas, I was able to significantly improve the number of pages Moz indexed from my site. Regular monitoring and adjustments are crucial to maintaining and further improving the indexing status.

If you’re facing similar issues, I recommend starting with a comprehensive audit of your site’s structure, content, and backlinks. Addressing these areas can greatly enhance Moz’s ability to index your site effectively.
