The pictures must be original and so as the content. Try to be creative and catchy as much as possible.. The more attention you get the more credits are in your favor..
I think it takes time to get credit. Its the same with me, I published a trip and haven't yet received a credit, Though my pictures and write-up are original
Original and quality content but if you didn't get any credit or email explaining why you didn't get a credit, please contact info@tripoto.com since seems an error to me
It takes about 48 days for them to review your blog and credit. You will receive a mail. If you still haven’t been credited, write to them on info@tripoto.com
