I agree; that last comment gives it away. I've been doing enterprise-level SEO for several years now as a day job and it's not as if algo updates are so frequent and far reaching as to make it difficult to keep up with. Most major updates from Google and the other engines are predicated on two major themes:
-Rewarding relevant, informative, keyword-rich content focused on specific topics and punishing sites that construct thinly constructed (UGC or otherwise) pages, particularly those who do it in huge numbers.
-Rewarding sites who links from similarly relevant, authoritative sources gained organically and punishing those who acquire links through artificial means (either through direct purchases, purchasing domain portfolios with thousands of backlinks etc.)
There are nuances that are market-specific that require slightly different approaches and concentrations (e.g. health care) but those are the main things folks should concern themselves with. There's no black magic behind it unless you're doing something shady to begin with.
