Today I will tell you why Google is not promoting your article. The reason is that Google is confused about the URL of your article. If you can clear up that confusion, Google will rank your articles.
There are many URLs on your site that are available in both HTTP and HTTPS versions. E.g.- http://techparimal.com/on-page-seo-techniques/, https://techparimal.com/on-page-seo-techniques/
If the URL of a page or post on your site is two versions, Google does not understand which version of that page or post you will rank.
So you need to find those URLs and replace them with anyone’s version. However, I would recommend that if SSL is active, change the HTTP to HTTPS.
