SEO in 2026 looks different from SEO in 2020. Three forces reshaped the discipline: (1) AI Overviews now appear above organic results for ~20% of informational queries, capturing the click before the user reaches position 1 — winning content must be cite-worthy enough that AI engines surface it; (2) Google's quality systems (Helpful Content, E-E-A-T scoring) heavily favor demonstrable expertise, named authors, original research, and first-party data over re-written generic content; (3) classical SEO ranking factors (technical foundation, backlinks, user engagement, internal linking) still matter but in a more compressed competitive band — small advantages compound less than they did in 2018. For Canadian SMBs, this means content quality bar is dramatically higher, but the rewards for clearing the bar are also higher because most competitors have not.
