The bottom line is there are two ways to get traffic to an article. Organic searches through a browser search using a search engine like Google, Bing, and etc. The other method is through social media marketing. In other words, posting at Facebook, using twitter, or posting at other social media sites.
To get organic traffic means when a person searches an interest by using a query with the search engine the result will be articles in a ranking order. Most people will choose an article on the first page or maybe from a few pages after. So, the goal becomes getting an article to be in that in range. That is accomplished by using Search Engine Optimization (SEO) techniques when writing the article. Yes, one element of good SEO practice is article quality. Also, an impact to consider is how popular a topic fulfilling a user's interest is.
The only suggest I have is to pick an article as a learning experiment. Based on the article think of questions a user may have that the article answers or the main topic from the title formed into a question. The title of an article is a vary key element of SEO.
Type that into the browser search window and see the results. You will see the ranking order of articles that the Search Engine provides to answer the query. Then if you wish look through the pages until you discover your article. A hint of the competition will be to check to see how many articles are produced by that search.
For instance, I have an article about leveling a concrete birdbath. It is a How-To article. It is also on DenGarden a niche site of HubPages. I just typed in the browser search 'leveling a birdbath'. My article is the first article on the first page. If I type in Concrete Birdbaths it appears on the second page of results at the bottom of the page. The title is 'How to Level and Adjust a Heavy Concrete Bird Bath'.
Another key element of SEO is keyword and phrases. As seen in the title the keywords were birdbath, concrete, and level. Those keywords are used in the article. When the search engine ranks an article that relationship is an element for it.
But, someone has to search that or something similar, which leads to how popular it is. Frankly, I get ten or less views a day from that article. And, that is my most popular article. But, it should be obvious there will not be a lot of people interested in that article. BTW . . . the search results are 202K for the first search I did.
I hope that helps . . .
