Catalog questions

Is it free to list my site?

Yes. Signal2 accepts a single listing per domain at no cost. Submit your site using the Add a Site form and it will be reviewed and added to the appropriate district of the gazetteer once confirmed.

What is Signal2?

Signal2 is a free web directory that catalogues reviewed sites across 22 subject districts. It operates on the model of a printed gazetteer — a systematic public record of online destinations, organised by subject and open for browsing without charge.

How are sites organised in Signal2?

Sites are grouped into 22 subject districts ranging from Automotive Trade and Transport to Voyages, Accommodation and Tour Operators. Within each district, entries appear in the order they were reviewed and confirmed. There is no ranking or scoring — all confirmed listings are presented on equal terms.

How do I submit a site?

Use the Add a Site link to reach the submission form. Provide your site address and select the most appropriate district. Your submission will be reviewed, and if it resolves correctly and fits the chosen category, it will be added to the Signal2 index.

Do you review all submissions?

Yes. Every submission is checked before it appears in the gazetteer. The review confirms that the submitted address resolves and that the site corresponds to the selected district. Submissions that do not pass review are not added to the public record.

How many sites are listed?

The Signal2 gazetteer currently holds 835 confirmed entries across its 22 districts. The index grows on a rolling basis as new submissions are reviewed and confirmed.

Can I update my listing?

To request an update to an existing listing, use the Add a Site form and include the relevant details. The review team will assess the request and update the record if the information is confirmed.

About the Signal2 catalog

Signal2 is a free web directory organised in the manner of a printed gazetteer, cataloguing 835 reviewed sites across 22 subject districts. Each district corresponds to a field of commerce or interest, from Gaming Houses and Wagering Venues to Voyages, Accommodation and Tour Operators. Entries are submitted by site operators and pass a basic review before being added to the public record. The index is designed for straightforward browsing rather than algorithmic ranking — visitors may navigate by district or search by keyword. Signal2 accepts submissions from site owners at no cost, adding confirmed entries to the relevant district as each review is completed. The gazetteer is updated on a rolling basis as new submissions arrive.
