KGR (Keyword Golden Ratio)

The Keyword Golden Ratio is a method for finding long-tail keywords with almost no competition: allintitle results divided by monthly search volume below 0.25. Here's the formula, the criticism, and when it still works.

The Keyword Golden Ratio (KGR) is a long-tail keyword selection method from Doug Cunnington. The formula:

KGR = allintitle results ÷ monthly search volume

Below 0.25 = the phrase has search demand but almost nobody has optimized a title tag for it. For a new site with no authority, these are the keywords where ranking in weeks instead of months is realistic.

Why it works (when it works)

Google ranks pages, but it also weighs exact-phrase signals in titles heavily for long-tail queries. If only 20 pages on the web put a phrase in their title, and the phrase gets 250 searches a month, your optimized page is competing against 20 casual mentions, not an SEO industry.

Where it breaks

  • allintitle is throttled and imprecise — Google caps results and the operator behaves inconsistently across regions.
  • Volume data for long-tail is sparse — small denominators make the ratio jump around.
  • It ignores SERP structure entirely — a KGR 0.1 keyword can still have a Wikipedia box, a forum thread, and two big-brand pages holding the top slots.

The fix: KGR + SERP verification

Use KGR as the cheap first filter, then look at the actual results page before committing. What to count: homepage results vs inner pages, big-platform domains (Reddit, YouTube, aggregators), content farms, and whether the top results actually answer the query.

That two-step — ratio filter, then SERP check — is what our keyword difficulty workflow automates: it computes the ratio where volume data exists and scores the live SERP structure where it matters.

FAQ

What is the Keyword Golden Ratio?

KGR is a keyword-selection method coined by Doug Cunnington: find long-tail keywords where the number of Google allintitle results divided by monthly search volume is below 0.25. The logic: if very few pages optimize their title for a term that still has search demand, a new site can rank quickly.

What is a good KGR score?

Below 0.25 is the original threshold for 'worth targeting.' Between 0.25 and 1.0 is borderline; above 1.0 means the title-tag competition already exceeds demand. The ratio only makes sense for long-tail terms under ~1,000 monthly searches.

Is KGR still effective?

As a standalone signal it has weakened — allintitle counts are noisy and Google throttles the operator. But as a quick competition proxy for new sites with zero authority it still filters out hopeless keywords fast. Use it as a first pass, then verify with actual SERP structure.

How is KGR different from keyword difficulty?

KGR measures title-tag competition only (allintitle). Keyword difficulty scores from tools measure backlink strength of ranking pages. They answer different questions: KGR asks 'how many people optimized for this exact phrase,' KD asks 'how strong are the pages I must beat.'
