The keyword golden ratio, KGR for short, is allintitle results divided by monthly search volume. Keyword.com and Mangools both teach it as the gate for underserved long-tail phrases a new site can rank for quickly: monthly volume under 250, and a ratio under 0.25, before you brief a page. Allintitle is a Google search operator, typed as allintitle: plus the phrase, that counts pages carrying the phrase in the title. Keyword.com credits the coinage to Niche Site Project.
HaloScan's API returns the ratio per keyword, beside the allintitle count and the results page. When a pull lacks the field, the division below computes it.
Keyword Golden Ratio Formula
KGR equals allintitle results divided by monthly search volume:
KGR = allintitle results / monthly search volume
Keyword.com states the two inputs as the allintitle count and the search volume, and says a lower score means a higher chance of ranking fast.
Get the numerator with an unquoted allintitle search. Keyword.com's worked example is typed allintitle:keyword research for affiliate marketing, words separated by spaces, and it counted 457 pages with the phrase in the title. Mangools describes the operator as pages that have all the searched words in the title, and says quotes lower the count and throw the calculation off. Mangools treats the phrase in the title as the sign that the page is targeting that keyword.
Get the denominator from one keyword tool and stay with it. Mangools notes that tools estimate volume differently, so relative size is what you keep: one phrase can show three times the searches of another.
Two worked cases show the math. Mangools takes best electric shaver for ingrown hairs, 22 title matches divided by 150 monthly searches, and states the score as 0.14. Keyword.com takes keyword research for affiliate marketing, 457 title matches divided by 40 monthly searches, which is 11.425.
The Under-250 Cap
Keyword.com says the method works to the fullest at a maximum of 250 monthly searches, because low volume is easier to rank for than thousands of searches a month, especially on a new site. Mangools requires volume under 250, because lower volume can rank faster and higher volume draws more competitors.
A ratio of 0.25 at that cap of 250 is 62.5 title matches. Mangools calls 62.5 the maximum you compete with under the strict rule.
Best electric shaver for black men showed 50 title matches against 1,100 monthly searches, which is 0.045. Mangools calls the ratio really great and the keyword fine, and places it outside the method because the volume is over 250. You may rank more slowly or not at all, Mangools says, and that page says the same of any keyword where competition is ignored.
Both guides loosen the cap once a site has traction. Keyword.com says a site with traffic from this content can later chase higher volumes, and a well-established site may rank those pages within days of publication. Mangools says a site that is not brand new and already has backlink authority can treat the formula as a guide, trying volumes around 1,000 a month or ratios up to 0.8 or 1.5. A new site stays under 250 and under 0.25.
What the 0.25 Gate Means
Keyword.com's aim is a score equal to or below 0.25. Scores from 0.251 to 1.0 can be used, behind the lower ones.
| Ratio | Keyword.com | Mangools |
|---|---|---|
| Under 0.25 | High chance of ranking high | Top 50 once the page is indexed |
| 0.25 to 1.00 | Moderate chance of ranking high | Top 250, pretty fast |
| Over 1.00 | Poor chance of ranking high | No rank target stated |
Mangools says a new site's article should reach that top 50 within a few days, sometimes hours. A site with decent authority that is not brand new is the case Mangools puts in the top 15, and the starting recommendation is still a ratio under 0.25. The 0.14 phrase goes to the front of the queue. The 11.425 phrase stays out, and Keyword.com says not to make it the main keyword of a page.
From the same shaver set, Mangools scores a phrase with zero title matches and a volume of 20 as 0, and 4 title matches divided by a volume of 30 as 0.13.
Which Tracked Terms Pass
- Keep terms under 250 monthly searches. Exactly 250 is inside Keyword.com's maximum and outside Mangools' under-250 line, so a new site drops 250 and above.
- Run the unquoted allintitle count for each survivor and write it beside the volume.
- Divide in a sheet. Mangools' sheet fills the allintitle link, calculates the ratio after you enter the count, and colors the cell green, yellow, or red from the ratio.
- Sort the under-0.25 rows first. That set is what you brief from.
Google throttles repeated allintitle searches, Mangools notes, and can ask for a captcha after too many in one period. Space the pulls.
Mangools' fair test is 20 compliant terms: about 5 percent rank better than expected, 15 percent worse, and 80 percent in the top 30 to 50, with that middle group moving up as content, authority, and competition allow. One compliant post can miss.
Does the Live Page Agree Anyone Targets the Phrase
A passing number still needs the live results page. Mangools says to Google the term before you write. Check that the top titles carry the phrase, then check the format. Online stores mean searchers tend to prefer those pages to an affiliate article. Videos mean they want a video. On a health phrase, Mangools says you are likely to see sites such as Mayo Clinic, WebMD, and medical journals. No similar site on the first page is a bad sign that the phrase can miss even with a strong ratio.
Keyword.com says to determine why the person searched, so the page answers that purpose. Search intent types are how you name that purpose from the results page.
Mangools says the ratio and keyword difficulty can both be right because they look at different things: titles on one side, link strength of the pages that already rank on the other. A passing ratio with a low difficulty score is probably a gem, in Mangools' words. Why the same keyword scores differently keeps that low score a separate input from this gate.
The green rows are the quick-win filter. Low-competition keywords are the wider shortlist a new site briefs only when the live page can be won.
Those titles and formats have to be the current page. qequals returns live Google results for the phrase on a Search call, so the check reads the page Google is showing.
Run the sheet, then open each green phrase. Brief it when the titles carry the phrase and the formats match a page you can publish. Hold the moderate band for later, and leave a score over 1.00, or a strong ratio over the volume cap, out of the quick-win queue.
