"Do you think it is better to target keywords with higher difficulty levels above 50 (according to Semrush) for a new blog, or should I focus on keywords with a keyword difficulty of less than 25?"
It is recommended to target both high-difficulty and low-difficulty keywords. Targeting keywords with higher difficulty levels will help establish your website’s topical authority, but you may not see immediate results. Focusing on long-tail keywords, which often include high-difficulty terms, can also be beneficial. For example, instead of targeting the broad term “cars,” you could target long-tail keywords like “cheap used cars in Des Moines, Iowa” which are likely to have lower difficulty. Aim for a balance by targeting keywords with okay volume (100-500 searches) and low difficulty.
