What Keywords Should I Use?
Researching Keywords and Traffic estimates

You’ve decided on the product or service that you want to sell when you start your online business. The next step is to find out what the online market is like for your product.
There are software programs that can do all this work for you. They will generate the keywords, compare the competitors in the market, give you estimates of traffic for those keywords and much more. They are worth investing in if you can afford it and we have some suggestions below.
However, if you want to get an idea before you start, the best place to look is Google. People search Google all day, every day. The words they input when searching for things are called Keywords or KeyPhrases. A keyword is single word but a Key Phrase can have a number of words. For example, Cake is a Keyword, Where Can I buy A Cake is a Key Phrase.
If you have a gmail or google account, you can access this feature free of charge. Search google for “Google’s Keyword Planner” and you will get a link to bring you to it. You can enter the keyword or key phrase that you think your customer would use and then Google will tell you how many people actually searched for those terms. You can select what countries you want to include too so if you are marketing in the United Kingdom for example, you can just choose UK and see the results there.
