One thing that you can try is sign up on several social bookmarking sites like digg, stumbleupon, pinterest, delicious, slashdot, reddit and more. There is a plethora of social bookmarking sites out there. You should register on all of them and post your content link and description on the sites. This can bring you traffic if you have great content.
Second thing is that improve the design of your website to your best. Create some good logo and improve the way the heading 'whatsappguru' is presented. I am saying this because your website is basically about media (mostly images). To improve the user experience you can also put up some interesting widgets on your website which will make visitors return to your website more often. Let me tell you, if a user comes to your website and he enjoys navigating through your website, then he may spread the word to his friends.
If you have a facebook page share the links of your posts on your facebook page.
Another thing is that you should comment on other popular websites in your niche and include the link of your website. Some website allow this.
The last thing I want to say is that make sure that your website is responsive (it should work well on smartphones, tablets and PCs as well). In addition to that make your website as fast as possible by technically optimizing your pages.
