As a web developer I will tell you that we routinely snag meta content from previous designs or sites and then strip out the tags we don’t want or replace them.
I would make absolute sense that if this project had many of the same keywords, to just open the html page from acorn and copy and paste it into the new site.
There are two possibilities
1. It’s possible that the people who designed/managed the ACORN website also designed this new website and simply used their code from one site on another to save time. (If you know tags are correct on one site, it’s easier to just cut and paste than have to validate another set of tags from scratch)
2. It’s possible that the person creating this site likes the ACORN site or it an active visitor to the site and simply hit the “view source code”, copied and pasted it into their new work. (For many self-taught designers, web wannabes they have no idea how to write meta tags, so they find a site they like and swipe the code from their pages.)
My guess is that it’s likely #2. BUT, it obviates the point that this person is a fan of ACORN - and is more than likely an active member or volunteer. So, while this is a good and interesting find, it’s not good evidence of anything other than the meta code was probably lifted from ACORN’s site.
Another thought is that they would use meta tags that would draw in a certain personality type and the specific type they would be looking for would be “Acorn” type personalities.
Therefor they had to know what “Type” was being sucked in by search engines, they had to know that Acorn had those specifics already in their tags.
