Hello Darcia. I would begin by understanding what HubPages (HP) calls a Stellar article. Here is a link to that article: https://hubpageshelp.com/content/Learning-Center-E...
Here is a link to the Learning Center, which is the HubPages Help site: https://hubpageshelp.com/ There are a lot of helpful articles there for writing articles. There are three categories there; Publishing Standards, Making Money, and Content Creation. You can always find the link to that site at the Help queue seen at the upper right. There is also a link to the FAQ too.
The article for a Stellar article will share information for substance, organization, and Grammar & Mechanics. Those three categories are used by the Quality Assessment Process (QAP). That process is by a human outsource at Amazon Mturk where readers assess the article. They use criteria to give a rating that our Hub Score comes from. There is different criteria for Creative Writing articles and Informational. Here is a link going to the Informational criteria: https://hubpages.com/help/hub_hop_table#informatio... You can toggle at a link at the upper left to go to the Creative criteria.
That assessment is combined with one done electronically. What that does is do things like do counts of words, capsules, and images. The QAP is where a HubScore comes from. Most importantly that is what is considered for an article to be Featured vs. being UnFeatured. Featured means it is Good to High Quality and is available to Google to be discovered by a user searching for information.
I hope that helps you with your New adventure writing and crafting articles while journeying on a learning experience. My recommendation is to just jump in the water and write, write, and write while learning along way.
