Search Volume means the number of potential prospects searching for that keyword in any given time.
This can be found using many tools, the most accurate being Google Keyword Planner.
Search Volume is important as you want to target keywords that have high numbers but are easy to rank for.
KD, or Keyword Difficulty, is a key metric in identifying how hard it will be to rank for that keyword.
If the keyword difficulty is too high, it may take too long to rank for that you’re better off choosing easier keywords and obtaining quicker traffic gains.
Current ranking simply refers to where your current website sites within the SERP’s.
If we see your website is already ranking between position 1-10, we should capitalise on those keywords first to get some quick wins on the board.
