Keyword difficulty scores describe the competition. They know nothing about you. A term scored 28 is unwinnable for a site at domain authority 8 and trivial for one at 55, yet both teams see the same green badge. The only test that matters is whether a site near your authority already ranks in the top ten for that term.

Why difficulty scores answer a different question

A difficulty score is built from the strength of the pages currently ranking. It is an accurate description of the neighborhood. It is not a prediction about whether you can move in.

What it cannot account for is the gap between you and them. Two sites with identical content get different outcomes on the same term if one has ten times the referring domains of the other. The score does not reflect that, so low-authority teams routinely build content plans full of terms they have no path to.

The result is predictable. Twelve months of publishing, respectable content, and nothing above page two.

The 15-point test

The rule we use: for any target keyword, look at the top ten results and ask whether one of them sits within roughly 15 points of your own domain authority. If yes, the term is winnable with good content and normal effort. If every result is 25 or more points above you, it is not winnable this year.

Fifteen points is a working threshold, not physics. It reflects the range where content quality and intent match can realistically overcome a site-level authority deficit. Beyond it, they usually cannot.

How to run the check in twenty minutes

Take your ten target keywords and search each in a clean browser session with location set to your target market. Pull the domain authority of all ten organic results using any metric you already pay for, as long as you use it consistently.

Then sort into two piles: terms with a result within 15 points of you, and terms where the floor is far above you. Publish against the first pile now. Revisit the second in two quarters, after your authority has moved.

The work is unglamorous and takes an afternoon. It also decides whether the next six months of production yields rankings or a portfolio of page-three URLs.

What happens when a team skips it

We took on a private-LLM infrastructure company at domain authority 17. They had 160 tracked keywords. 158 of them sat on pages 2 through 10. Zero top-three rankings anywhere. Traffic had fallen roughly 70 percent across two Google core updates, from 1,200 visits a month down to 367.

The content was not bad. The targeting was. Every term had been chosen from difficulty scores with no check against what their authority could support, so a year of production landed just outside the range where anybody sees it.

The recovery started with what they already had. They held position 18 on a 1,000-volume term and position 24 on an 880-volume term, both already within reach. Moving two existing pages from the second page to the first is a different kind of work from publishing thirty new ones, and it pays back in weeks rather than quarters. That sequencing is standard in our B2B SEO practice: fix what is close before you start what is far.

The gaps are real, and they are findable

This is not an argument that low-authority sites cannot rank. It is an argument for looking first.

In live US checks we ran in September 2026, a site at domain authority 13 held fourth position for “ai marketing consultant”. Page one for “performance marketing agency for saas” included sites at DA 4, 12, 17, 20 and 24. Those are not hard terms for a small site. They are open doors, and they were sitting next to terms where page one ran DA 30 to 47.

The difference between those two sets of terms is invisible in a keyword tool and obvious in a SERP.

Pull your current top ten target keywords tomorrow morning and check the authority of everything ranking for them. Any term where the weakest result outranks you by 25 points or more comes off the plan this week. A Growthym crawl will tell you what your authority can carry, but the keyword cut is one you can make on your own, today, before another quarter goes into terms you cannot reach.
