Exact Match Domain is King?

So any SEO worth their paycheck knows that exact match domains are a big part of the SEO game and the top search results, but what exactly is the science behind that?

If Google has the advertised 200 factors being considered when coming up with 100% of the final figure that determines the order in the SERPS, how much of that is exact matching a domain?

An exact match domain is basically the domain name for your exact search.

If you are a customer searching for the finest Charlotte web design company, you may type in “Charlotte web design”. This is a high volume, high competition and high skill level search result. You will find here companies making a living putting good, usable content. But, as in most searches, you will also find the guy who used the incredible skill of “buying the name first”.

Why would this be such a heavily weighted factor in Google’s quest for the most relevant and fresh quality content?

Google beats us over the head with their message of “content is king” and telling us to “write good usable content for you customers not for search engines". Google then goes out spidering sites and gives perhaps 10%? 20% consideration to the guy with the domain name purchased fastest?

Remember 20 years ago when anyone that was selling car insurance could easily be found by customers under their OTHER name “AAAAAInsurance”?

SEO of 20 years ago consisted of putting a lot of AAAA’s before you company name to appear first in the phone book. The phone book had an algorithm of exactly one factor, Alphabetical.

Now 2 decades later we have the world’s most advanced search technology yet it still seems to decide contextual relevance by the name you put on it. If I write “War and Peace” on the front of a phone book does that make it an award winning novel?
