A data aggregator is a company that collects information about businesses, such as name, address, phone number, categories and opening hours, and supplies it to other platforms: directories, map services, sat-nav systems and apps. The idea is that you correct your details once at the source and the correction flows outwards, instead of fixing each listing individually.
How data aggregators work
Aggregators build their databases from many inputs: official records, telephone directories, business submissions, web crawling and data bought from other providers. They then license that data to anyone who needs business listings, from small online directories to navigation and mapping products. When a directory shows a listing you never created, an aggregator or a chain of resellers is often the explanation.
In the United States, a small number of large aggregators sit at the top of this chain, and much local SEO advice written for American businesses tells you to submit to them first. The UK does not work quite the same way. Listings here are fed by a looser mix of sources: Companies House records, long-established UK directories such as Yell and Thomson Local, map and location-data companies, and directories copying one another. Some US aggregators do pass data to a few UK sites, but their reach here is narrower and shifts as data deals start and end.
Why it matters
Consistent details across the web support your local citations and help Google and other services trust that your name, address and phone number are right. The bigger risk is wrong data spreading. A business that moved from Croydon to Sutton three years ago can find its old address reappearing on directories it has never heard of, because a source further up the chain still holds the old record. Customers ring a dead number or turn up at an empty unit, and correcting each copy by hand never seems to finish.
Aggregators also matter when you choose a listings service. Many citation tools sell “distribution to the major aggregators” as their headline feature. For a UK business that can mean paying for a US-centred network that reaches only a fraction of the directories your customers actually use.
Common mistakes
- Following US checklists. Submitting to American aggregators and assuming the UK is now covered.
- Buying a distribution package without asking where the data goes. Ask any provider for the list of UK sites it updates directly, and which it reaches only through third parties.
- Fixing the copies, not the source. Editing one wrong listing while the feed that created it keeps pushing the old details.
- Overlooking your own records. An old address on your website, in an email signature or on a stale Companies House filing can feed the problem.
- Cancelling a paid service without checking the exit terms. Some services stop maintaining listings, or let them revert, when the subscription ends.
How to act on it
Begin with the details you control. Settle on one exact format for your business name, address and phone number, then make your website, Google Business Profile, Bing Places and Apple Business Connect match it. Your registered office at Companies House does not have to be your trading address, but neither should be out of date.
Next, search for your business name alongside old addresses and old phone numbers to find where incorrect data lives. When you find a wrong listing, check the site’s terms or data page to see where it sources information. If several wrong listings share an origin, fix that origin first and the copies often follow.
Before paying for any aggregator or listings service, ask which data sources feed UK directories at the time you are buying, because these arrangements change. Confirm which sites will be updated, whether changes are permanent and what happens if you stop paying. Managing this properly is part of the local SEO work I do for UK businesses, and I check current UK coverage before recommending any service.
