The Earth-Domains fit Earth Day quite specifically: Earth-Domain is the Domain of the Day.
A forwarding from the new ecological Earth-Domain to a De-Domain or Com-Domain is possible without any problems – even the other way round, there are no problems.
The connection between better ranking and the new top level domains has been proven by a study of Searchmetrics for the Berlin-Domains. Websites with Berlin-Domains often rank better in Google for regional search queries than websites under the De-Domains and Com-Domains. The result of Searchmetrics‘ study can be summarized as follows:
"For 42% of search queries .berlin domains rank better locally."
The study of Total Websites in Houston shows that the results of Searchmetrics are generalizable to all New Top Level Domains, so also to Earth-Domains: it found that Google takes the domain extensions of the New Top Level Domains as a key element for the evaluation of the domain. Total Websites concludes:
"It is clear that the new top level domains improve search engine rankings."
