Keyword Golden Ratio (KGR) Guide

Updated October 7, 2026

What Is the Keyword Golden Ratio?

The Keyword Golden Ratio (KGR) is a data-driven method for finding under-served long-tail keywords, popularized by Doug Cunnington. It compares how many pages use a phrase in their title with how many people search for it.

The KGR Formula

The allintitle count comes from searching Google for allintitle:your keyword phrase, which returns pages containing every word of the phrase in their title.

How to Read a KGR Score

Worked Example

Suppose a keyword has a monthly volume of 100 and an allintitle count of 18. Its KGR is 18 ÷ 100 = 0.18, which falls in the strongest range. A keyword with volume 100 and 140 allintitle results scores 1.4 and would usually be skipped. These numbers are illustrative only.

Limits of KGR Today

• Volume data is rough at these low levels, which makes the ratio sensitive to small changes.
• Titles are not the whole story. Pages can rank without the exact phrase in their title.
• It ignores who ranks. A low KGR does not tell you whether the top results are strong sites.
• Allintitle counts vary and are slow to collect by hand for large lists.

Use KGR as one filter, alongside a look at the actual results and SERP weak spots.

Calculating KGR in Bulk

Checking allintitle by hand is slow. LowFruits includes an Allintitle and KGR tool that adds both values to a keyword list, at 1 credit per keyword; large batches can take a while to fetch. Pairing KGR with LowFruits' weak-spot data gives you both signals in one view. See how to use LowFruits for the steps.
