Early in my internet marketing journey, I stumbled across something that taught me a valuable lesson about keyword research and ethics. I was browsing keyword data and noticed that mesothelioma — the disease caused by asbestos exposure — had staggeringly high cost-per-click values. We are talking about keywords that could pay fifty dollars or more per click. The reason was obvious — personal injury lawyers were bidding aggressively to reach potential class action clients.

The Keyword Research Experiment

My curiosity got the better of me. I ran the keyword through a niche keyword research tool and found long tail variations with virtually no competition. I had already proven with a previous project that you could rank quickly for ultra-low-competition long tail keywords. So I figured — why not test it with a higher-value niche? I threw up a quick 300-word post targeting one of those long tail phrases and waited to see what would happen.

That experiment lasted about four hours.

The Ethics Check

Almost immediately, I felt uncomfortable. Here I was, adding throwaway content to the internet designed to capture clicks from people dealing with a serious, often terminal illness. When I looked at the search results, the niche was already full of the same low-effort, exploitative pages. It was a race to the bottom, and I did not want to be part of it.

I called my friend and mentor Garry Conn to get a gut check. His reaction confirmed what I already knew. My blog — and my approach to internet marketing — was not about gaming the system with made-for-adsense pages. It never had been, and it should not start now.

So I pulled the content down and walked away from the experiment.

What This Keyword Research Experiment Taught Me

Looking back, this experience taught me several lessons that still hold true in 2026.

High CPC does not equal high opportunity. Just because a keyword pays well does not mean it is a good fit for your business or your conscience. Many high-value keywords are saturated with aggressive, well-funded competitors. Others exist in niches where the audience deserves better than thin affiliate content.

Your brand is your reputation. Every piece of content you publish reflects on who you are. If your keyword research leads you to a niche that makes you uncomfortable, trust that instinct. There are plenty of profitable niches that do not require you to compromise your values.

Long tail keyword research still works. The underlying strategy of finding low-competition long tail keywords and creating targeted content remains one of the most reliable approaches to organic traffic. The key is applying that strategy in niches where you can genuinely help people.

Get a second opinion. When you are unsure about a direction, talk to someone you trust. Having a mentor or peer who will give you honest feedback is invaluable. My conversation with Garry took five minutes and saved me from going down a path I would have regretted.

The Bottom Line

Keyword research tools are powerful, but they are just tools. They cannot tell you whether a keyword aligns with your values or your audience. That judgment call is yours to make. Chase keywords that let you build something you are proud of, and you will never have to delete a post four hours after publishing it.
