Show Content According to User's Google Search

I have a website which contains blog on different categories. I want to create a section which will display blogs on topic related to the user's Google Search. This is similar to what Instagram does, if you search about something then they will show sponsored posts according to your search, they are obviously not using Google AdMob. The website Quora also does something similar, if you a open a question page on the website, they will show you related question on the right corner based on your search. Just to conclude I want to mention again that I don't want to display advertisements using Google AdMob, I want to show my website's content. Any help on this would be much appreciated.
