The website above isn't needed but can be a good tool to avid traders. The script alone is fine.
Weav3r uses API keys to get almost every bazaar listed to it's users. So it's not completely necessary to sign up. You will want to have his script install though so you can see what other bazaar prices are at. Most likely, your bazaar isn't low enough to compete with the others.

i want to know how they can change their URLs to just bazaar,trade or anything how did they do it
You want any URL shortener... there's dozens to choose from and many of them include browser extensions to make it quick.
one last question i did make a raffle to our own faction(PI 2675 happiness) and it’s a flop i don’t wanna do it in fun and games yet cause im just gonna get bountied saying its a scam i did it for 25m per ticket i thought it was a good price as to what they will get is the price too high? Or there’s something more that i did wrong?
Well, considering you don't have the PI that you're auctioning off in your own list of properties, it's a massive red flag. You may be legit, but it doesn't look like it from an outsiders perspective. If you want the property to go to your own faction do it in your faction forums or your faction's discord server.
