Iv been doing SEO for a couple of years.
Iv realized the number of pages and their individual PA is quite relevant to increasing DA.

Currently trying to do the same with PlayGround Zero
A tip I can provide is to make sure you are spreading your backlinks around your entire website.
If the majority of backlinks are linking to the homepage and it has a PA of 90 while all other pages are struggling to get up to a PA of 20-30, your DA will never increase above 10 max.
Whereas if all pages on your website have a PA of 40+ you can easily reach 20 DA.
On a side note DA doesn't really help much with ranking or organic traffic.
