I think the internal links is a big factor too - had a new-ish 50 page site take a -950 hit a few weeks ago, removed a bottom navigation menu that linked all the pages together (the menu used page titles, which on reflection must have looked like keyword-stuffing) and after 3 weeks of literally zero Google traffic it's starting to recover - several pages back on page 1 and others working their way back up.
