Keyword Research, Simplified - Allintitle Checking and Keyword Golden Ratio

Daniel Nguyen | 15 min read

Allintitle checking and Keyword Golden Ratio (KGR) are frequently regarded as the most outstanding time-saving features in WriterZen by our supportive community - the Zenners. But what exactly are they? And what can they contribute to your content writing process? Well, as we dig deeper into this article, I am sure you will get a satisfactory answer!

Allintitle Checking: The Basics

Allintitle is an operator that helps us query Google to find out how many titles (how many articles are indexed by Google and likely to appear on the SERP) contain a particular keyword. Since it tells us the number of articles about any given keyword, the Allintitle index indirectly tells us that if we choose to rank 1 for a keyword, how many other articles will we have to compete with. In other words, it reflects the competitiveness of the keyword in some way.

Here is an example of how the Allintitle index works:

When we query Allintitle "coffee machine", Google returns 1,200,000 results. This proves that 1,200,000 other paths (articles) also write about the keyword "coffee machine". In other words, we are competing with another 1,200,000 results.

Understanding how Allintitle works will help us find keywords that compete with the fewest competitors (the fewest articles). This is an important way for SEO-ers to analyse and select keywords effectively and less competitively.

How Allintitle Works in WriterZen

As an important index that helps us find a good keyword, WriterZen integrates Allintitle testing in the Keyword Explorer tool. We enable you to check Allintitle up to 100,000 keywords monthly non-stop and effortlessly, depending on your plan. You can check Allintitle in two ways, by the button "Check Allintitle" on the first page of Keyword Explorer, or you can check it later in the Keyword Data tab.

The Allintitle feature allows you to quickly search for and identify all the titles by competitors which use the exact keywords as your seed. By extension, the Allintitle feature also enables you to separate keyword chunks that have low competition (low Allintitle) but have a high Search Volume - Golden Keyword Ratio (KGR), which means that these words require far less effort from your end to lead far more organic traffic into content than your competitors!

From the knowledge base of Allintitle, let’s now explore in further detail about Keyword Golden Ratio - the golden metric that enables you to achieve niche and effective keywords!

Keyword Golden Ratio: The Basics

Keyword Golden Ratio (KGR) is also known as the golden ratio for keywords. This ratio helps us identify keywords with low levels of competition that easily rank top on Google searches without having to invest a lot in resources. Typically, if you choose a keyword with good KGR, the keyword will immediately appear on SERP after writing and being Google indexed. Therefore, this is a fundamental index in keyword research and is very suitable when exploiting the niche. Additionally, Keyword Golden Ratio is a metric that shows how many other pages are competing for the same keyword. The lower the KGR, the better the chances to rank high on Google.

Keyword Golden Ratio (KGR) was developed by Doug Cunnington - an Internet Marketing Consultant and a Project Management Professional (PMP). You can learn more about his work via the website

As defined by Mr. Cunnington, the Keyword Golden Ratio is:

“The number of Google results that have the keyword phrase in the title is divided by the monthly Search Volume, where the Search Volume is less than 250.”

The formula for KGR is, hence: KGR = Allintitle / SearchVol

How KGR Works in WriterZen

After much research and having worked with KGR for some time, we realised that the current definition of KGR, though effective, doesn't cover different cases with keywords that stay out of the 250 Search Volume range. Therefore, based on the core formulation of Doug's original work, we developed our own algorithm to classify different classes of Golden Keywords, as below:

KGR = Allintitle / SearchVol x ClassRatio

Where "ClassRatio" is a ratio we developed to classify values for 3 different keyword levels as follows:

    • Level 1: Top value keywords - Low Allintitle competition & high Search Volume
      Allintitle < 100 & Search Vol >100: KGR range 0 - 30
    • Level 2: Medium value keywords - Low Allintitle competition & low Search Volume
      Allintitle < 100 & Search Vol < 100: KGR range 30 - 70
    • Level 3: Low-value keywords - High Allintitle competition
      Allintitle > 100

With this new formula, you can look for keywords at any range (in terms of Search Volume and Allintitle data) to match them in the keywords group that best fits your strategy.


Some of you might be under the impression that the formula for calculating KGR usually limits the Search Volume to a certain level under certain circumstances. But when the WriterZen team ran tests on many keywords and measured them in various project settings, we found that to choose keywords that are easy to rank and bring great results (sales or traffic), the index that we need to limit is mainly on Allintitle. We have two main reasons for arriving at this conclusion:

  1. When our Allintitle is low (and it's only 100), we're essentially only competing with 100 other competitors. Our article just needs to be improved in terms of content in this situation. Moreover, when we are indexed again, Google will prioritise us, and the probability of our article appearing in the SERP will be much higher than otherwise (i.e. writing with a single keyword with high Allintitle).
  2. A high Search Volume keyword will generate more traffic for the article, thus making it easier for us to sell. If we limit Search Volume with this thought, lower Search Volumes will not indicate less competition. This is because, even though there are too many competitors due to high Allintitle, we are still competing with a large number of competitors in essence.

To show more clearly the effectiveness of KGR, let's look at the following example after checking the KGR indexes for the keyword related to “coffee maker with grinder” with a length of 6-12 characters.

We see that the keyword “coffee grinder bed bath and beyond” at the time of this writing had an average Search Volume of 1,600. This is a volume that is not too small according to the KGR calculation; in some other places. So, this keyword will not be selected.

But ask yourself this: What is WriterZen doing?

WriterZen calculates a KGR of 0, which is the ideal ratio. Compared to that, even this example shows a very worthy keyword to choose because the Allintitle is only 8 (i.e. close to 0). That means we are only competing with 8 other competitors. This almost guarantees that we can index it and appear right on the SERP when we finish writing the article.


KGR shown on WriterZen can be defined differently by many parties. But WriterZen has researched KGR extensively, measured it in large numbers, and verified it using multiple, unbiased users. So remember to use WriterZen to find keywords with Allintitle <=100 and KGR in 0->30 and get to TOP SERP hits!
