I think anyone who has a business has some experience in web research. It's the first place anyone goes to research their business idea. If you are thinking about starting a home based business, then I do have a few suggestions as where to start.
The fact web research is an interest of yours is a good sign that you are probably starting the right business. But it’s a lot more to starting your own business then starting something you like. Make sure you are even compatible with entrepreneurship. Do you even have what it takes to start your own business?
Next I would find out if there is a need for another web researcher that will enable you to enter the field. Do you have to have your own business or are you willing to work for a company as a web researcher?
I would then move on to researching who your potential clients would be. Think about who will purchase your service, how will you attract clients, and can you accumulate enough clients that can replace your current income?
These are just a few suggestions to get you started! Good luck and I hope this helps.
