Interesting, will have to ponder how to spin yarn from this.
Two keyword niche phrase abc def (three letters each) with 78,000 results on G and 1,500 on C
Jumping from 1st to 10th page of results for this term shows 280K results on G but still 1,500 on C
Paradoxically: 1st page rankings similar but distinctly different :)
It'll all come out in the wash...
Edit: opening a 3rd browser and seeing 280K results off the bat. Infrequent searches cause realtime adjustments?
