Why this is different from generic fare sites
A row of fares is not the same thing as a useful recommendation.
That is the gap SERP Radio is trying to close. Instead of stopping at a low number or a temporary drop, it tries to make the market state readable enough that you can say: this looks favorable, this looks normal, or this looks overheated.
The product is closer to a market read than a deals blast.
A deals site is usually optimized for discovery and volume. SERP Radio is optimized for route context, timing context, and state changes that help a reader act with more confidence.
That is why the product can be rendered into route pages, market signals, and watchlists without changing the underlying truth. The system is trying to produce a usable read, not just a list.
Use SERP Radio when the question is not 'what exists?' but 'what matters?'
If you need a live route read, open the route page. If you want the broader market story first, open the broadcast. If you want the operating logic behind it, read the about and system-flow pages.
