While launching a new website there are many On-Page ranking factors that matter the most on SEO. Also, I regularly follow the Moz Blog for the SEO updates and activities i need to follow.

The points are:

High Quality Content.
Keyword Optimization.
Page Title and Meta Description.
URL Structure.
Page Speed.
Internal Linking.
These are the few points one should keep following to improve ranking on SERP.
