Free Lead Lists, and What They Are Actually Worth

Search for lead lists and you will mostly find people selling them. Underneath that there is a layer of genuinely free, genuinely public business data that covers a surprising amount of what a small agency needs.

It is worth knowing what is there, if only so you stop paying for things you could have had.

Company registers

Most countries publish a searchable register of registered companies — name, registration number, address, incorporation date, often the directors. In the UK it is Companies House, in Denmark the CVR register, and so on across Europe.

The incorporation date is the underrated field. A company registered in the last year is making decisions about its web presence right now, which is a different conversation from one that has had the same site for a decade.

Trade bodies and professional registers

Regulated trades keep public membership lists: electricians, plumbers, dentists, accountants, opticians, estate agents. These are maintained because the public uses them to check credentials, which means they are kept current.

They are also small, local and specific — exactly the shape of list that lets you write something a recipient recognises as being about them.

Maps and local directories

Google Maps is the broadest free source of local businesses, kept current by the owners themselves. It tells you whether a business has a website at all — which is the single most useful field on the page for this purpose.

Regional directories still matter in some markets, especially where a long-standing local listing site predates Google. Worth ten minutes of checking for your area.

Where free data falls short

• No contact person — registers give a company, rarely the individual who decides about the website
• No email — almost never included, in any of them
• No quality signal — nothing tells you whether the website is any good
• Inconsistent formats — every source exports differently, and merging them is its own afternoon
• Dormant entries — registered companies that have not traded in years still appear

The honest comparison with paid lists

A paid list is usually the same public data, merged and tidied. You are paying for the merging, not for access to anything you could not reach.

Whether that is worth it depends on how much of your time the merging would take. What you are definitely not buying is the quality signal — commercial lists do not contain it either, because producing it means opening every website, and nobody selling a ten-thousand-row list has done that.

The step that is never free

Whichever source you start from, you end up at the same place: a list of businesses that needs to become a list of prospects. That means opening each website, loading it on a phone, and deciding whether there is work worth selling.

Doing that properly runs to several minutes per business, and most of them turn out not to be worth contacting. It is unglamorous, repetitive, and the single largest cost in the whole process.

That is the step LeadCrawlr automates — it finds the businesses for a trade and area, opens each site, and ranks them 1 to 10 on the signals that indicate neglect, with businesses that have no site at all listed separately. The free sources above remain perfectly good for what they are good at.

A reasonable approach

Use the free registers for sectors where credentials matter and the trade body keeps a list. Use Maps for anything that serves walk-in customers. Skip paid lists unless you have a specific reason that is not "it will save me time" — because the time it saves is not the time that is expensive.
