I’m not going to call these guys cheaters because technically they aren’t. The problem is that they are playing a dangerous game and there’s no reason to.
The text at the very top of the page, and I’m talking about the key phrases that you can BARELY see. Guys, it is possible that google would consider that hidden text by just looking at the code and seeing the colors be almost the same. If they do, then you might get banned. Just make that text in white or something.
Why take the chance? It’s sloppy SEO that you shouldn’t jeopardize your business with.
