People need to learn what the word "penalty" means.
I have seen so many people talking about their sites being penalized for something due to Google algorithm changes. For example, "Oh, XYZ used to work, but now Google penalizes you for it!" and how do you know that, Mr. Hypothetical?" "I used to be ranked at the top of Google, and now I'm on the second page!" Okay, so that constitutes a penalty how, exactly? "Well, obviously they didn't like it so they knocked my site down!"
This is not how things work. Whether it was an exact match domain, a certain kind of backlink, using certain anchor text, or what have you, you were probably doing it because it provided a benefit. If that thing no longer provides the benefit it once did, then, it isn't providing a benefit. That's not necessarily a penalty.
If I give you $100 for your birthday, am I penalizing you on the day after by not giving you $100 again? Of course not.
This inability to distinguish a lack of benefit from a penalty has people running around talking about how sites shouldn't do X, or Google hates Y, all because their site or sites aren't getting the same rankings they used to. Frequently the people who are doing this were completely dependent on this same X or Y for all their results. (Incidentally, if your entire business is built around a gimmick, well, you deserve what you get.) These people can't isolate whether they are being penalized or not because they don't have any other variable to test. It just contributes to all the noise and silliness that already exists in that world.
For people discussing SEO and website building practices: choose your words wisely. For people looking for information on how to rank your sites or smart SEO methods: consider these words when deciding who to listen to or who to buy from. It makes it easy to identify the frauds.
Also, since I rarely look at the WSO area, have there been any "LEARN HOW TO AVOID THE EMD UPDATE PENALTY" products posted yet? I wouldn't be surprised at all.
