Sixteen Google updates, drawn as five transit lines. Each line is a question Google kept asking: is it good, is it trusted, does it work, does it understand me, can I rely on it? Tap a station, then audit a real site against the whole map.
Stations run left to right in time. Tap one to see what it changed and what to practise. Tick boxes in the audit lab below and exposed stations light up pink.
Open a real website (your own, a client's, or a competitor's). Tick every statement that is true for it. You're finding the updates it would be exposed to.
Pairs audit the same site, compare ticks, and agree on the three costliest risks. Defend the order using the map.
Pick a station, predict which results will rise or fall, then open it in the simulator and check your prediction.
Apply two fixes to a practice site, re-run the audit, and write 150 words on which risk was hardest to remove, and why.
