Question about metadata

I would like to know if I make some edit in description, keywords of my online track. Will All of these affact metadata system ? Will it make any change in order on searching system.?

Actaully, I ask this question cuz I want to make an edit for my description and I'm afraid that It will affect in order of metadata.

Thanks in advance

you can change description and tags anytime.
tags and title are most important, the description is not so much.
concentrate on those tags and, as ive heard (but didnt follow) the titles.

but i see you have pretty good tags and description, why would u wanna change them?

Thanks @LivingroomClassics. I always make links to another tracks in my description. So, when my new track is approved I usually make an edit in some previous tracks that's related to my new track. So, I'm just afraid that doing this many times (editing previous track to link to the new one) may cause an affect in metadata in some way.

i doubt...
