Earlier quoted context omitted.
That's a pretty unrealistic moral in the face of the reality of how the consumer web works. I mean, I get the whole "don't depend on another company for your revenue" (e.g. apps in the Apple app store), but you're saying "don't count on Google sending traffic to your site". Plus, her ranking didn't change -- her site vanished out of the index. EDIT: Unless you mean "don't depend entirely on organic traffic"? I can so…
How did you infer the site was deindexed? They said specifically by typing the URL of the site, it would show up.
"...but if you look for photo quilts or any similar search term, Portrait Quilts — which for years was always the top result — no longer appears."
I'm being a little imprecise, but her site was deindexed for a bunch of search terms that she used to rank highly for.
