You should focus on keyword difficulty in keyword research. Keyword difficulty tells you how hard it will be to rank for a specific term. You need to know this before targeting a keyword. If the keyword is too competitive, it will take more time and effort to rank. You can start with low to medium difficulty keywords. These keywords are easier to rank for. As your site grows, you can target more competitive keywords. Balancing keyword difficulty with search volume is key. Focusing only on easy keywords may limit your traffic. So always consider keyword difficulty in your research.
