Let me teach you the allintitle trick

Let’s assume URLs without the keywords in the title tag are not competitors, we can know the real numbers.

Using allintitle:keywords you will return URLs with keywords in the title tag.

Below 5 000 results, consider the query low competition. Between 5 000 and 10 000 results, it’s medium. Above 10 000, it’s highly competitive.

You can also use intitle: but results are looser.

There is nothing scientific in my tip, but it’s been working for me since I started SEO in 2004.

Moreover, it’s as scientific as Keyword Difficulty scores by SEO Tools.
