If you are اینورتر جوشکاری for online products then this will help you. I am going to give you some ideas for products that you can create online that will be profitable.
Software
If you have some skills in developing software then this is a hugely popular and profitable type of online product. Everyone likes and wants software that is going to make their life easier and save them time or money. Developing software for these purposes can generate huge amounts of income providing you have done your market research and you already know that people are looking for that kind of software.
Some people sell software but they actually outsource the task and hire someone else to do the software development. If you decide to do this you just need to make sure that you have fully understood what the terms will be for that software and what kind of support you would get to fix any bugs that might become uncovered.
Membership sites
People love to be part of a community and therefore membership sites are quite popular. If you are able to provide a membership site for a targeted group of people and produce high-quality help and advice on a regular basis then you will find that you are able to generate a good recurring income.
Your membership could be an ongoing one if you have enough material to keep adding to it or it could be for a fixed period of time such as a one year long membership.
Information products
Everybody is looking for information when they go online and if you are able to package that in an easy to understand format then people will pay for that information. Information can be sold in many different formats such as written, audio or video.
You can also add coaching as an additional source of income whereby you help people and give feedback to people to help them implement specific information and help.
