Hello, I found some good keywords. How can I obtain the keywords' tbmler (search volume, CPC, keyword difficulty)? Do I need just a niche sector or can I achieve this value with articles and content? I currently have 20 keywords in hand. The volume is 5.8 K, CPC is $67, and keyword difficulty is 44%. What should I do to achieve this CPC value? Thank you, have a nice day.
