If you want to know how to find out the SEO competition, or the number of results in Google for a given key-phrase, just look at the grey text located under the Google search field form.
Obviously you first need to search for something in order to see the number of results ranking for that key-phrase.
As you can be seen in the following images
the keyword “seo expert” had a Google competition of about 14,800,000 results in 2013. And in 2019 the competition reached 135,000,000 results and it’s still increasing monthly.
So in 6 years, the competition increased exponentially.
That’s why I recommend to start a SEO campaign sooner than later. If today the SEO campaign is affordable for you maybe next year it will not be.
