jaya-surya Ah that's great thank you for clarifying. At the moment the majority of your traffic is coming from India which traditionally has a low EPMV.
To help you to achieve you goal of $3 - $5 I would first of all recommend linking your Google search console to Ezoic https://pubdash.ezoic.com/nicheiq/webmaster-auth and then waiting the 4 days for the data to start to appear and then enable NicheIQ topics.
Topics are evergreen keywords that are linked to your domain niche. It saves you hours of work doing keyword research. Alongside this these keywords are within reach for your site and are updated weekly so as your site grows so does the difficulty and traffic levels.
After thirty days of building out this content I would then recommend alongside this regularly checking the SEO report https://analytics.ezoic.com/reports/seo/searchConsole which shows the keywords from search console and the corresponding visits and EPMV. You can then use this information to build out content in areas that are providing you the highest EPMV.
I'd also recommend using Flickify and Humix to help your standing with Google and your revenue as well
