Fuller, Tires, and Pothos: A Pitfall Documenter's FAQ on Cleaning Up B2B Keyword Lists

I've been handling B2B content and equipment spec orders for 9 years. I've personally made (and documented) 12 significant keyword mistakes, totaling roughly $14,800 in wasted budget. Now I maintain our team's checklist to prevent others from repeating my errors. This FAQ is what I wish someone had handed me in 2017.

Here's what this FAQ covers:

• Why did our keyword list include 'fuller' and 'william fuller md'?
• What do 'fuller brushes' and 'woolly bear' teach us about search intent?
• How did 'tires' and 'how to make pothos' waste our budget?
• When is paying extra for a keyword audit worth it?
• What's the checklist before approving a keyword list?
• What's the one question most buyers forget to ask?

Why did our keyword list include 'fuller' and 'william fuller md'?

Because someone dumped a broad-match list without checking intent. In my first year (2017), I made the classic keyword-dump mistake: I treated every phrase with traffic as a lead. 'Fuller' is a perfect red flag. If you're Fuller in energy/mining equipment, 'fuller' alone collides with Fuller brushes, William Fuller MD, Fuller House, and a dozen other meanings. 'William Fuller md' isn't a B2B mining query. It's a person. That's not a keyword. That's noise.

According to Google Search Central (developers.google.com/search/docs/fundamentals/creating-helpful-content), Google's systems prioritize content made primarily for people, not for search engines. So if the searcher isn't your buyer, the content won't help either of you. We wasted $3,200 on a campaign before I caught it. The fix wasn't magic. It was adding a one-line intent check: 'Would a plant manager or procurement lead type this?' If no, it's out.

What do 'fuller brushes' and 'woolly bear' teach us about search intent?

They teach you that words don't have a single meaning. 'Fuller brushes' is a real product—but not mining equipment. 'Woolly bear' is a caterpillar, a weather folklore, and sometimes a band. None of that belongs in a B2B equipment funnel.

The 'fuller brushes' disaster happened in September 2022. We published a blog post hoping to catch 'fuller' traffic. It attracted DIY crafters and people looking for pet-safe brushes. The result: 47 sessions, zero qualified leads, and a $890 redo plus a 1-week delay on a better piece. When I compared our Q1 and Q2 keyword lists side by side—same vendor, different review process—I finally understood why intent matters more than volume.

Bottom line: a keyword isn't a keyword until you know who's typing it and what they want next.

How did 'tires' and 'how to make pothos' waste our budget?

Because broad terms look cheap until you pay for the wrong clicks. 'Tires' could mean mining haul truck tires, or it could mean a sedan owner searching for winter tires. 'How to make pothos' is a houseplant propagation query. Neither one tells you the searcher is ready to spec a slurry pump or a crusher liner.

On a 47-keyword list where 42 had zero buying intent, we burned budget fast. The mistake affected a $3,200 campaign. We caught it after a week of bad traffic. That error cost $890 in redo plus a 1-week delay. Not ideal. But workable—after we added negative keywords and intent qualifiers like 'mining', 'industrial', 'OEM', and 'spec sheet'.

Here's what you need to know: broad-match junk doesn't just waste money. It trains your team to chase traffic instead of buyers.

When is paying extra for a keyword audit worth it?

When you have a deadline and no room for 'probably.' In March 2024, we paid $400 extra for a rush keyword audit. The alternative was missing a $15,000 product launch. The audit wasn't perfect, but it was certain enough. It caught 11 bad terms before they hit our campaign.

After getting burned twice by 'probably on time' promises, we now budget for guaranteed delivery. The value of a rush audit isn't the speed—it's the certainty. A cheap list that looks fine on Friday can cost you a week of cleaning on Monday. That's not a saving. That's a delayed loss.

Don't invent emergencies. But if your launch date is fixed, the extra fee buys you a decision you can defend. In that case, it's usually a no-brainer.

What's the checklist before approving a keyword list?

After the third rejection in Q1 2024, I created our pre-check list. We've caught 47 potential errors using this checklist in the past 18 months. Three things: intent, source, deadline.

• Intent: Would a buyer, engineer, or procurement lead search this? If it's 'woolly bear' or 'how to make pothos', cut it.
• Source: Where did the keyword come from—competitor gap, search console, or a random export? If no source, it's a red flag.
• Deadline: When do you need the content live? If the deadline is tight, pay for a verified list instead of guessing.

The checklist isn't glamorous. But it's faster than explaining another $450 waste on 15 wrong keywords. And it keeps the team from repeating my 2017 mistake.

What's the one question most buyers forget to ask?

Most buyers focus on search volume and completely miss search intent. The question everyone asks is 'how many searches?' The question they should ask is 'what is the searcher trying to do?'

If you've ever pasted a keyword list into a content brief without opening the top 10 results, you know the sinking feeling when the draft comes back about Fuller brushes instead of Fuller mining equipment. That's not a writer problem. That's a brief problem.

So before you approve the next list, ask: 'What job is this searcher trying to finish?' If the answer is 'make a pothos cutting' or 'find a doctor named William Fuller,' you don't have a keyword. You have a detour. Cut it, and spend the budget on terms that actually match your buyer's day.
