Ah..., I think the mistake most investors make is that, they just get an article to the webpage, sit down and expect clicks.
Before even writing an article, there should be a target audience, else it would all be a waste of time.
Yes, there is a target audience, but did the article get to the target audience? After submitting an article on your blog, you should try to spend at least $5 on that article via targeted ads, when done you can now sit back and hope on God because you've done your path.
Do you also consider public sentiments before submitting an article on your webpage, most people drive away traffics from the websites with their articles.
Let's say you sell wears on your website and you need traffics, writing an article on the importance and advantages of looking good will certainly catch the eyes of the audience, promoting such an article on social media using a landing page first will certainly catch people's eyes, however, within the article, you need to know how to present those click buttons that will lead a user interested on wears to your website. Most people will end the article at the point where it got so much interesting and expect the user to continue the reading by navigating to the website.
Even aged articles can still generate much leads if only you can rebrand, re-date the article and do a little promotion on the article. Going through this peace of write up, you can see where the keyword density is situate, "Article". Even Google bots can easily tell that the piece of write up is all about articles.
It is not the number of articles on a webpage that matters, but the quality, because you expect your users to keep coming back.
