# A change is the starting point.

Compare basic website change monitoring with commercially contextualized intent signals.

A changed page is an observation. Understanding why it could matter to a merchant is the next step.

## From a page difference to a next step

A page monitor identifies a change on a selected page. SignalTally combines broad collection with machine-learning filtering and a product direction focused on commercially useful notifications and agent workflows. Confirm the coverage and delivery required for your use case.

## Evaluate on your own workflow

Choose representative merchants and define what a useful event looks like. Review the source, timing, relevance and work required to act. These comparisons describe approaches, not a feature audit of any named vendor.
