Hi Trish, I've applied for the same more than 5 times. Everytime when i had applied it was rejected with a note 'Insufficient content' It was more than 6months by then. again i applied with a new article with almost a thousand words. Turned out it was rejected too. At the end, I buckled up and wrote an article with more than 1500 words. Finally my application was accepted. Now its working all fine from past few months and good news is I've started making some cents. Its a slow process and for you it will be your next priority. So according to my experience with Google Adsense, you have been here for about 6months, as per your profile. Now write an article which has more than 1500 words and must adhere to T&C. It will work out then.
Nothing to worry about, keep writing. To be precise keep writing longer articles which will help you get through with Adsense. Later on article may have lesser words which is fine, once your account is approved. All the best. [Smiles]
