/ 01 — Sample previewSee what's in the file

Five rows from the full 22-row dataset, sorted by rating & review count. The full file has one row per business with 16 columns: business name, email, email type (business or personal), phone, street address (with postal code), city, state/province, country, Google rating, review count, website, email quality, audit date, and any other emails and phones we found for the business with where we found them. The CSV adds email_2, email_3… where a business has more than one address. Service-area businesses (mobile mechanics, handymen, cleaners) deliberately don’t list an address on Google, so that column is blank for about 2% of rows.

/ HelpCommon Questions

How do I choose a reliable marketing agency in St Thomas?+

Start with the rating — look for a marketing agency holding 4.5 stars or higher with a healthy number of recent reviews, which signals consistent, current service. Confirm they're properly licensed and insured for the work you need, and read a few reviews to see how they handle problems, not just praise. The listings below are sorted by Google rating to make this easier.

What's the typical cost of a marketing agency in St Thomas?+

Pricing varies widely by the scope of the job, materials, and how urgent the work is, so there's no single rate. The most reliable approach is to contact two or three marketing agencies directly for a quote on your specific situation. Use the "View on Google Maps" or "Visit Website" buttons on each listing to reach out.

Are these marketing agencies verified?+

Yes. Every listing is sourced from public Google Business Profile data — business name, rating, and review count — collected by our own crawl. We show only what's already public; we don't add or alter business details.

How can I contact a marketing agency?+

Click "View on Google Maps" to get directions, hours, and the business's public contact options, or "Visit Website" to reach them online. We don't publish private phone numbers or email addresses here — the business's own Google profile and website are the right place to get in touch.

I'm a business owner — how do I update or remove my listing?+

Go to publicleads.com/your-business. You can remove your business or an email address, or fix your phone or email there; we email a confirmation link first, and nothing changes until it is used. For anything else, email support@publicleads.com.
