KGR : Trouver des mots-clés longue traîne avec une faible difficulté de référencement

There are many strategies for selecting topics for a blog and using the Keyword Golden Ratio is one of them. In this article, our experts explain what the Keyword Golden Ratio is and how to use it to your advantage.

Definition of Keyword Golden Ratio

The Keyword Golden Ratio (KGR) is a Data-Driven strategy for finding long-tail keywords that are underutilized in Google search results pages.

The ratio is the number of Google results that contain the keyword in the title, divided by the monthly local search volume, when the search volume is below 250.

If you find a Keyword Golden Ratio phrase and publish content targeting that keyword, your article should rank in the top 10 within days – sometimes hours. If your site has decent authority and is not brand new, then you can rank in the top 5.

What is “Allintitle”?

Allintitle is an advanced search operator from Google, which displays results from websites that have an exact combination of words selected in the meta title of an article.

How to estimate the difficulty of keywords with the Keyword Golden Ratio method?

Let’s take as an example the KGR of the keyword “best shaver for men”, the procedure will be as follows:

First, we start by defining the search volume of “best shaver for men”, which is 7’310 according to Keyword Surfer.

Search volume allintitle

Search volume allintitle


We then obtain the number of allintitle or search results, which in our case amounts to 3’150 results.

Search volume allintitle

The KGR for “best men’s shaver” is 0.43 (3150/7310).

Any KGR less than 1 is worth using in publications and blog posts if the search volume is less than 250. Since we find more than 7,000 results in the search volume for “best men’s razor”, we should probably ignore it, even if the KGR is less than 1, if we strictly follow the following KGR rule, which is:

  • If the KGR is below 0.25: You should rank in the top 100 once your page is indexed by Google.
  • If KGR is between 0.25 and 1: You should still rank in the top 250 fairly quickly.
  • If KGR is greater than 1: This means that the search term in question is competitive and it will be difficult to rank for that keyword.


To recap, the rule is to write articles that target keywords with the following characteristics:

  • Less than 250 search volumes
  • Less than 1 KGRs. If they are less than 0.25, even better.

How do you use a keyword tool to find KGR terms?


Let’s continue with the razor example. To find KGR terms using a keyword tool, in our case KWFinder, you need to follow these steps:

One of the best ways to find KGR-compliant terms is to use free tools that Google offers such as Google Autosuggest, which allows you to get KGR keyword suggestions by typing keywords into Google search:

Filter out keywords with a search volume greater than 250

Keep in mind that KGR requires the search volume to be less than 250. This means you can set the filter to get rid of keywords that don’t matter to you.

Enter 250 for the MAX search volume in the filter.

You now have many options with a search volume of less than 250. You can add other criteria to the filter such as a KD max of 15, 20, 25, etc.

Find the number of websites whose titles exactly match the ones in the list

You need to check the allintitle, the advanced Google search command.

Insert allintitle and the search phrase without spaces or quotes (quotes will reduce the number of results, which will skew your calculations).

We see that there are 22 results, which can be integrated into the formula.

KGR = (allintitle results) divided by (search volume)

KGR = 22 / 90 = 0.14

With a result of 0.14, we have a term that is consistent with the KGR.

KWFinder also has excellent metrics for each keyword, allowing you to do a competitive analysis without leaving the application. This is a huge time saver.

Difficulty finding KGR terms:

Finding keywords is a skill that can be improved over time.

Using tools like KWFinder can make it easier, of course, but you have to put in the time.

Keyword ratio in SEO: What is the right keyword density?

The keyword density is a measurable indicator that designates the number of appearances of a keyword in a given article. It is also called keyword frequency.

Keyword density allows SEO experts to determine if their main keyword is present in the content of a web page.

The keyword density index is simply the rate of presence of the targeted keyword in the written content.

Use the following formula to get this indicator:

ID = (NO/NT) X 100

ID: Keyword density index

NO: Number of occurrences of the keyword in the article

NT: Total number of words in the article

Most SEO experts believe that the ideal keyword density is around 1 to 2%. This means that the target keyword appears about one to two times per 100 words. At this rate, the keyword appears enough times to show search engines what the page is about, without over-optimizing the keyword page.

Ultimately, the Keyword Golden Ratio is probably one of the best techniques for optimizing your SEO. It can change the way you look at long-tail keywords, so you can be sure that your content will get the attention it deserves. The important thing is to target keywords that aren’t too competitive, and the KGR rule is one way to do that.
