Welcome to the Q&A Forum

For onsite links, it takes time to get indexed depending on the age of the domain and the domain authority of your website. Generally, it takes 72 hours for the links to get indexed, but if it doesn't happen, you can request forceful indexing through the webmaster. For more information, you can contact Bester Capital Media. I think the experts there can help you further in this regard.

The following are some of the ranking factors that Moz uses to determine page authority. I got them from an article on Bester Capital Media:

1. Social signals, such as the number of Google+1’s, Facebook Likes, Twitter Retweets or LinkedIn Shares a page has received.

2. The number of root domains linking to the page.

3. The number of root domains linking to the page using partial match anchor text.

4. The number of subdomains that link to the page.

5. The number of quality websites linking to the page.

6. The number of external links a page has.

I hope they help.
