Your data for PMD column is inaccurate.
No it's not. But if you think it is, then it's a good idea to explain why you think it. Because I can't read your mind.
It could be that you consider the word "galactic" to be a partial match for space travel, it could be that you consider the directory "/space" to make the domain a partial match, or it could be that you think the extension ".space" makes it a partial match. Either way it's wrong, but you need to clarify your position.
Thank you for more thorough information, yet the point is as also the message of this thread that, while trends changed the companies already knew of it and took the advantage of the partial matching domain keywords for their business despite EMD opportunities - as is also well established pratice in traditional business naming (example, 'Eat at Joe's' and not fully descriptive as 'Eat a Snack'). And that doesn't necessary was/should standing for the internet marketers where EMD was a fair chance to get into competition - for a market share(redistribution). Regards
You're confusing correlation for causation.
Businesses like "Joe's Diner" have been around for longer than the Internet, let alone search engines. So even though joesdiner.com is technically a PMD, it likely wasn't chosen for SERP bonus.
This is why people tend to stick to EMD:s in these arguments, because it's very difficult to discern the intent and purpose of a PMD. Even with spaceadventures.com you could argue that it isn't an exact match in the same sense
as spacetrip.com. Because people looking to travel to space are more likely to look for [trip to space] or [space trip] than they are for something seemingly arbitrary like [space adventures].
At the end of the day this thread is about Mueller's comments, and these aren't new. He's been communicating these ideas to developers for years.
Some domainers are resistant to it because they've invested money into these kind of domains, and in this case they rather not have the truth getting in the way of future deals. But as the old saying goes, "the truth doesn't mind being questioned, a lie doesn't like being challenged."
