Google lists them under Locksmith (3), Key duplication service (2), Safe & vault shop (2), Emergency locksmith service (1), Handyman/Handywoman/Handyperson (1) and Hardware store (1). A business can carry more than one category, so the counts overlap.

Question 6

Is Page One Partner free to use?

Accepted Answer

Yes. Page One Partner is a free directory of local service businesses across the United States. It costs nothing to search, and nothing for a business to be listed. Each profile is built from the business's public Google Business Profile, and an owner can claim, update or hide theirs at any time by contacting info@pageoneinsights.com.

Question 7

How are businesses ranked?

Accepted Answer

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.

Question 8

What do Recommended, Verified and Sponsored mean?

Accepted Answer

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.

Question 9

How current are ratings and hours?

Accepted Answer

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.

Question 10

Who publishes Page One Partner?

Accepted Answer

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.

Question 11

Why is my business listed here?

Accepted Answer

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.

Question 12

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

Accepted Answer

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.

Question 13

Do you sell or share my information?

Accepted Answer

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.

Question 14

How do I correct or remove my listing?

Accepted Answer

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.
