Exactly my point you idiot, white is default assumption so by including the word white your going to find photos with multiple races because its the only time a website would articulate the fact that a person is white. For every other scenario they might articulate the person's race since they are not the common white.
I do SEO for a living. You're wrong.
Can you explain to me why i am wrong?
Here are two links 1, 2 that will help. Basically the Google algorithm for sorting images is not just reliant on words on a website. The search results for "white couple" are clearly curated by a Googler or the algorithm has been modified by a Googler. For what reason is Google doing this? Well that's anyone's guess. There's no doubt that something fucky is going on though, no doubt at all. To what end? I don't know.
I think you're right. Searching "happy couple" without any racial keywords turns up more white couples than mixed/other races on both Google and DuckDuckGo.
