Hi DP members i want to ask a question from the Experts, that optimize single keywords like Cancer , Depression ,Asthma .I am going to start on these keywords for my medical website, can any one tell me how much time it will take...please reply soon.. my website has page rank 3.
Am not an expert, but from my point of view, it is better to target long tailed keywords if you want your domination in front page of Big G. For single keyword like ones you mentioned, it will take loads of months to make it to top page of Google. It is a different scenario if you outsource it and have a long term view.
These keyword you mentioned is really competitive, it might take ages even if you keep on building backlinks and update you website. Try to aim some long tail keywords, with a website of page rank 3, it might be much easier for you to rank high.
