FAQ
What makes a keyword "blue ocean"?
Blue ocean keywords combine meaningful search volume with low competition — you can realistically rank with quality content instead of competing against giants. The Blue Ocean score rewards that ratio.
What is keyword difficulty (KD)?
KD is a 0-100 estimate of how hard it is to rank on page one, based on the backlink profiles of the current top 10. Lower is easier.
Which difficulty filter should I choose?
New sites: start with 20. Established sites: 35 finds more volume. Any shows everything sorted by score.
It says no keywords found — why?
Very niche seeds may return few suggestions, or the difficulty filter may be too strict. Try a broader seed or raise the difficulty limit.
