Choosing an AI visibility tool starts with choosing the measurement method you need. This guide distinguishes a one-off check, a broad topic index and repeated monitoring of your own questions. It is not another numbered vendor ranking. Semly publishes this guide and is a provider in this category.
Three methods answer different questions
| Method | Useful question | Limitation to check |
|---|---|---|
| One-off checker | What appeared in this particular sample? | It does not establish a trend or cover every answer |
| Topic or prompt index | Which topics and sources should we investigate? | The index may not represent your exact questions or market |
| Custom-prompt monitoring | How does a fixed set of buyer questions change over time? | The result depends on the selected sample and configuration |
A platform can combine these methods. Ask which one produced each displayed metric. Similar score names do not make the underlying data comparable.
Define scope before comparing platforms
Record country, language, system or product mode, questions and dates. Separate Google AI Mode from AI Overviews. An API response is not automatically the same as an answer in a consumer interface. Keep collection failures separate from successful answers without the brand.
Check the denominator
The share of answers mentioning a brand differs from the share of questions with at least one mention. A composite score, position or sentiment is a different measure again. Ask how competitors, aliases and multiple mentions are handled. Do not add percentages for overlapping entities without knowing the overlap.
Run an acceptance test
- Add a small set of questions relevant to a real buying decision.
- Open an answer and the cited page; check whether the classification matches the text.
- Inspect a previous measurement and the handling of a failed collection.
- Write one task for an existing page, including the missing fact and its source.
- Confirm who can edit or publish content and what the selected plan includes.
This is a proposed evaluation process, not a vendor effectiveness benchmark. A source page being cited does not establish why the platform selected it.
Features should be checked in current documentation
Semrush documents competitor, prompt and source analysis; it should not be described as lacking source analysis. Its wider toolkit also includes brand-performance reporting. Check the relevant module and subscription rather than inferring that every feature is in every plan. Semly combines monitoring with work on content; verify the available configuration and publication process for the chosen destination.
Total cost and the next step
Compare the same number of brands, markets, questions, systems, users and required history. Record billing period, extra charges and content limits. Subscription cost and analyst time are separate. Use current provider terms instead of copying prices into several overlapping guides.
Once a tool is selected, keep a stable measurement series and use observations to verify public information. Update an existing page when it already serves the reader’s need; a new article requires a distinct question or documented example.
