Most SEO targets the high-volume, high-CPC quadrant, which is also the high-difficulty one. The low-KD/high-CPC corner is thin but nearly uncontested.

Eight pages from this filter earned more than 40 high-volume informational pages combined.

So what: difficulty and commercial value are not correlated as tightly as people assume. The cheap-to-rank, expensive-to-advertise corner is where the margin lives.

Benchmark of the week: only 1.7% of keywords in our sample sat in the KD-under-25, CPC-over-$6 quadrant.
