If you were to follow the keyword search research steps laid out by Do in his video, then I think that it would be plausible for a company to obtain the number one spot on Google search pages because your research would result in an effective, popularly searched keyword.
However, I don’t think you would be able to stay at the top because certain factors such as consumer demands and new competitors in the market can change, meaning that the consumers might search for products using keywords different from what your company had obtained through their research. In order to stay on top, your company would have to conduct new keyword search studies in order to modify their keywords to stay at the first result.
