THE RADAR

What changed in AI search, rated by how much to trust it.

Every finding here says how much to trust it, links to the source it came from, and says plainly when nobody has confirmed it. When an earlier issue gets something wrong, the correction runs in the issue that found it, not quietly in the original.

All of it readable in full, because a claim you cannot check is not worth making.

Know what changed, the week it changes

Google shipped a control that can make a site invisible to AI Overviews entirely. Finding that out three weeks late costs you a quarter. Get the Radar in your inbox and you will hear about it while there is still time to act: one short email, every claim sourced, sent only when something actually moved. Some weeks nothing does, and those weeks we send nothing.

How this is put together

Every claim is read at its source before it is written up, and the source is linked so you can check it rather than take our word for it. Where we could not find a primary announcement, the issue says so and reports it as second-hand. Where an earlier issue got something wrong, the correction runs in the issue that found it, not quietly in the original.
