Matt Cutts in 2011, cred ca e valabil ce spune chiar si astazi: How important is it to have keywords in a domain name? - YouTube - mai ales finalul, de la minutul 2:30 inainte...

Apoi, eu am zis ce-am constatat eu, din experienta proprie.

Ideally, webmasters should strike a balance between finding a catchy, unique, brand friendly domain name with having a domain that contains keywords that they are trying to target.

For readability sake, a domain name that is longer than 3 words should be separated with hyphens. That said, use of hyphens also correlate with spamminess so domain names with more than 3 words should be avoided.

Inca ceva: eu daca as fi Google, in mod sigur nu as acorda prea multa "greutate" numelui unui domeniu; nu cred ca ar fi fair-play.

In plus, nu am zis ca nu mai au putere, am zis ca nu mai au o putere atat de mare...

Probabil ca nu sunt chiar atat de "adânc" in eroare.
