I was trying to be dramatic, yet polite, so I went after "grandma" phrases.

Worked fine imo.
Well CB niches can be pretty spammy. I literally got a site for one of the top 10 products (not anymore) still in top 10 with 2K word homepage article, 20x300 word articles as support and really shit outsourced PBN links. No idea how it's still sticking there honestly. Did my portion of CB stuff in the past, no longer focusing on that and you can rank pretty easily there with shit links. Though it's nothing long term for sure. CB niches behave differently. They are new keywords, everybody is trying to rank them, amount of spam is higher and then search volume starts to fall down and people stop pushing the sites. New keywords behave differently than established ones. It's day and night difference. But as a rule of thumb, it won't work in non spammy niches. You can try that with amazon for example and it won't get you far IMO.
Shame CB went to shit. Few years back, the amount of awesome products being launched was huge. So much money there to be made. And now it's just shite.
