If I learned anything from music uploading and having a music site of my own is that it's not the quality of the music you post up that really matters anymore, it's simple it is to get the music is all that matters.
You need to get a template so damn simple that a 14 year old girl looking for the latest taylor swift song to cut herself with can get.
Link shortening, oh bb allah, pls don't go there. Not yet at least! You need your name out first. Meaning, you want it so that when people share a link to a song that you uploaded, it doesn't have adf.ly cause honey, no one is touching shit with that shit smothered over it.
Make a redirect page instead or better yet, get a frame on top with your site name "mp3loverz" or some shit. Embed an iframe or some shit while the person is going to download the song, be creative. Point is, you want your site name smothered. And guessing how you're probably uploading from a server, get an rdp and start changing album tags to your site. Trust me, it helps a shitload. This extra step seperates the average wordpress music album site from the one who takes an effort to get people be like "oh ya i just found this site that is pretty good, you just click the link to the song and it takes you to the download" MEANING, NO SHITTY HOSTS. None of this mirror sites. Hell to the no. Get something like RGHost or something that doesn't have distracting ads. By distracting ads I mean that shit that has "le iLivid Download Here" stupid shit. Man that shit is wack.
Also, I suggest getting rid of that index page and instead, make it just album covers and buttons with "download" or something of the sort because or else, 100 uv/day is all you'll ever get within the first month before google notices you and starts making you eat dirt.
Use as much text possible and the least amount of images.
Make it optimized for mobile already, and no, ditch that shitty looking mobile template wordpress gets a hard on for, seriously, that shit is ugly and unattractive. Make it so that when someone is in desktop mode, it's already very optimized.
Also, make each song individually available for download. I shit you not, your stats will go so high, California will wonder what the fuck you're smoking.
Now I know, it's hard work, it really is. But trust me, if you focus on the delivery of the content first, audio quality is the least of your worries.
I didn't proof read this because I could care less about my english atm because frankly, choppy english is wj's forte for the past years.
bro.
