https://www.ecosia.org/ seems to have no issue with neocities (whereas searching neocities in duckduckgo does not show it except in the wikipedia callout).
It's the same problem. Search for "fauux" (one of our more popular web sites) and you'll see other sites talking about one of the more popular sites but you won't see a link to the site itself.
