From the site:

"...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.

based on how misinformed the author was in general on the subject, I think its more likely the site dropped off the first few pages of results. Since it still came up when you search for the domain, it can't be deindexed.

Again, apologies for the imprecision. But you'd agree that it has been delisted for search terms it used to do well for?

Additionally, far less than <1% of the people who use Google get past the second page of results. Getting your ranking penalized by twenty spots is a death sentence.
