I normally operate for main searches in the 20-30 million range. This one was just over 11 mill.
More importantly to me, internal pages are also ranking very well.
Using the number of returns as a guide to how competitive a search term is is fundamentally flawed.
What really matters is how aggressive the competition/seo is on the first few pages pages.
The number of returns, especially given how flawed the count is, can often be irrelevent.
