How quickly are AI models’ perceptions of a brand likely to change?
Weeks to months for most narrative shifts, faster on retrieval-heavy engines and slower on engines anchored to older training baselines. We track every change in AIQ so the trajectory is visible.
Two factors set the pace. The first is the engine’s source mechanics: retrieval-heavy engines (Perplexity, Google AI Overviews, ChatGPT Search) can reflect new authoritative content within hours to days, while engines weighted toward their training-data baseline (older ChatGPT configurations, Claude in some modes) often need weeks for meaningful shifts as the broader web ecosystem catches up. The second is what is being changed: a factual correction (a date, a title, a single sourced claim) moves faster than a tonal shift in how the engines describe the brand. We track both in AIQ™ across all eight engines, which means clients see the trajectory in their monthly reporting rather than waiting for a final answer. The realistic expectation we set at the start of an engagement is weeks to months for visible narrative change, with steady progress in the data along the way.
