I use two different programs to help me pick my long tail keywords. First I use Long Tail Pro and select at least 5-word terms that have a "Keyword Competitiveness" score of 30 and under. If they pass that test I take the same word and go to ahrefs and then see if the term has a "Keyword Difficulty" score of 15 or under. Does anyone here do something similar? Should my competition numbers be for both be lowered? Thanks.
