How are businesses ranked?

Recommended businesses first, then businesses that have claimed their profile, then Verified ones, then by Google rating and review count. Use Sort to see highest rated first. Sponsored placements can appear at the top of a page, always labeled Sponsored, and they never change how the rest of the businesses are ranked.

What do Recommended, Verified and Sponsored mean?

Recommended means the business is a client of Page One Insights, the company that publishes this directory. It is a business relationship, not an independent rating, and Recommended businesses are listed first. Verified means the business's Google Business Profile is owner-verified with Google and we have a second confirmation it is real: a Page One Partner specialist spoke with the owner on a setup call (shown as "Verified by phone" with the date), it is a Page One Insights client, or it carries at least five Google reviews. Sponsored means a business paid for that placement; it's always labeled and never affects ranking.

How current are ratings and hours?

Ratings, hours and contact details are pulled from each business's Google Business Profile and refreshed daily, so what you see here matches what's on Google.

Who publishes Page One Partner?

Page One Partner is published by Page One Insights LLC, a local marketing company based at 111 NE 1st St., Ste 8646, Miami, FL 33132, in business since 2024. You can reach the team at +1 (888) 272-1940 or info@pageoneinsights.com. The company is listed with the Better Business Bureau under its legal name.

Why is my business listed here?

Because it is a local service business with a public Google Business Profile. Page One Partner lists businesses the way a phone book or a map does: from public listings, not from sign-ups. Only the facts already published on Google appear here — name, category, city, hours, rating and website. Nothing private is collected or shown.

Did someone sign my business up, and is there a charge?

No one signed you up and there is no charge — not to be listed, not to claim a listing, not to correct it and not to remove it. Nobody from Page One Insights will ask for a card to keep a listing online. The only paid product is a clearly labeled Sponsored placement, which is optional and never affects how your listing ranks.

Do you sell or share my information?

No. Page One Insights LLC does not sell business or personal information. Quote requests sent through a listing go only to that business. See the Privacy Policy for the full detail.

How do I correct or remove my listing?

Open your listing and use Claim this business, or email info@pageoneinsights.com with the business name. Corrections are applied by a person after a quick verification, and removal requests are honored — no questions asked.
