Hello,
Google Earth has its own ranking and they use 360Cities information for this ranking like:
- If the panorama is an editors' pick or not.
- How many likes/unlikes it has.
- How many views the pano has.
So, old panos will be shown with a zoom out and new panoramas will be shown with a close zoom, very often.
You can add a good description to your panorama, try to get a lot of views and you'll be able to see your panorama from a zoom out.
Regards,
Elena
