Publish more articles targeting long tail keywords so that your site will have a better chance of showing up for more keywords. The more keywords your site shows up for, the more clicks and traffic you will get from Google and you will see it reflected in your Google Analytics account.
Another method you can use to increase the number of search queries driving traffic to your site is writing longer content. So, instead of writing 500-word articles, write 1,000 to 1,500 word articles. Longer articles will contain more relevant words that will match the keywords people search with on Google regarding the topic you are writing on.
It's not only about writing longer articles though. You have to write well-researched articles. For better results, look for some lsi keywords using your favorite keyword research tool and sprinkle them within your article.
If you do all these, you will rank for lots of keywords and your search queries will rise dramatically.
