AJ code bad for Search Engines?

When I google my username ,track name and tags, i’ve noticed that my Soundcloud and YouTube accounts show up in the search results but no sign of AJ. Although all accounts have been created around the same time still their is no sign of my AJ account in the search results. Do you think the backend code is not very crawler friendly or did I miss out on something here…

This is a very enigmatic problem. I can not understand it too.

AJ on the sixth page of google for “Royalty Free Music” . Maybe why there are only few customers around ….
