From what I see, there is a page called For Developers which explains exactly how you can update the data for your software applications. I believe that all your questions will be listed there. The 4th questions explains exactly how to add the correct data to your applications listed on Software Informer. Alternatively, access the pages for your apps, and then click on Suggest a correction links found on the left side. Add the data and if it's correct, you should see the changes. I believe this is the correct procedure.
