So they open up their browser, type portrait quilts in the address bar, which redirects to a search, and your website is on page 8 despite being an exact match on the search. Game Over.
Seems your other channels are not quite as effective as you thought if google decides to penalise or blacklist your site. If you're off page 1 or 2 you may as well not exist. Of course from Google's point of view, you'll just have to advertise with google, so this doesn't penalise them at all, in fact they are rewarded monetarily for arbitrarily shifting rankings periodically (not that I'm suggesting that they go out of their way to do this, just that the perverse incentive is there).
Personally I find Google is providing results which are less and less useful, with their recent emphasis on monetising search, indifference to fairness, and lack of transparency as to their ranking methods - it certainly seems as if in this case a draconian penalty has been applied, and there is no effective way to appeal or even find out what the judgement against them was (webmasters very often is not helpful). A penalty of a few places would be completely understandable if they don't like this site for whatever reason, a penalty of 8 pages while other spammy results dominate search terms is not.
I've switched to DuckDuckGo for now and it's pretty good. Compare the results for Tipex (a popular brand of correction fluid in Europe) for example:
