Currently I have 110$ to spend in adwords for PPC, I want to give them a go but I realized about keywords & am not sure what to do about researching them... List your research methods below?
You just have to use a keyword research tool or tools that bring out more terms that fit your business. First, it is important to think about the keywords on the customers' perspectives. Then use keyword tools like Google Insights or the most common one, Adwords, to expand your PPC keyword list and, at the same time, to find out the new keywords are being searched on.
