Why does my .EUS website have a 0 PageRank?
The PageRank classification was used in the past to measure the importance and interest of websites but it has not been updated since 2013 because Google has discontinued it. As the .EUS websites were set up from 2014 onwards, they do not have any scores in this classification.
Nevertheless, as the classification no longer operates and as the search engines do not take it into consideration, not having a PageRank classification will not in any way affect the positioning your website has among the search engines.
