Improve your image loading times. They wouldn’t load on mobile.

Change your font to common one. Sorry, it’s distracting.

Add call to actions at the middle and bottom of your posts.

Add internal linking in your posts.

Reduce the amount of related posts to 3.

Add a strong call to action on your home page.. featured post for example.

Remove the footer credit. It has negative effects for search engines.

Hope it helps!
