Okay, I’ve been experimenting a lot with MFA sites lately and every site has more then 200k pages to be indexed, so i took several domains new and old, less/no backlinks and some with 4000+ backlinks, so here are the main factors of indexation.

• If you have more backlinks that means you will be crawled more often then others.
• If you have more relevant content to your niche through out the site that will only speed up the process.
• More content is always good as long as its relevant.
• Getting blog reviews makes it better and keeps up activity.
• Social bookmarking is very important.
• Sitemaps are optional if you have alot of backlinks.
• Relevant backlinks from sites in the same business gets you authority.
