Advertising within ChatGPT is one of the more interesting developments in paid digital marketing this year.

For law firms, the potential is easy to see. People are already using AI tools to research legal questions, understand unfamiliar terminology and get a clearer idea of their options before deciding whether they need professional advice.

The arrival of advertising within that environment opens up some interesting possibilities. It also raises an obvious question for legal marketers: can law firms actually advertise on ChatGPT?

At FireTap Legal, we’ve been following the development of ChatGPT Ads closely and have had early access to test the platform for legal sector advertising. Combined with OpenAI’s published advertising policies and guidance, that has given us a useful insight into where the opportunity currently stands for UK law firms.

How does advertising on ChatGPT work?

ChatGPT Ads are still relatively new, and the advertising product continues to develop.

There are some important differences from traditional paid search.

Google Ads is often very good at capturing existing intent. Someone searching for “conveyancing solicitor near me” or “probate solicitor in Manchester” has given a fairly clear indication of what they’re looking for.

A conversation with ChatGPT can start much earlier.

Someone might ask what searches are needed when buying a house, what happens if a person dies without a Will, or what rights they have if their rented home needs repairs. They may then ask several follow-up questions as they begin to understand their position.

That gives ChatGPT much more conversational context than a single search query.

OpenAI’s guidance to advertisers reflects this. It encourages ads that are useful and relevant to the conversation, with messaging suited to different needs and circumstances rather than simply reproducing a traditional keyword-led advertising campaign.

For professional services, where people often spend time researching before making contact, that could eventually become a valuable advertising environment.

For legal services, however, there is an important restriction.

Can law firms currently advertise on ChatGPT?

Under OpenAI’s current advertising policies, ads promoting legal advice, legal representation or legal services to individuals or businesses are not permitted.

The policy gives examples including immigration, personal injury, legal claims and document preparation, although the restriction isn’t limited to those areas.

OpenAI does make an allowance for general legal education and media where legal services aren’t being offered.

That potentially leaves some room for legal information and educational content, but the distinction isn’t necessarily as clear in practice as it first appears.

We have encountered the Legal Services restriction first-hand when testing the platform, including where advertising has been focused on educational legal content rather than directly promoting a legal service.

That experience doesn’t tell us that all legal educational content will be rejected. OpenAI’s own policy specifically allows for the possibility of general legal education and media.

It does suggest that law firms need to be careful about assuming an educational article will automatically be eligible for advertising.

Landing pages matter

An important part of OpenAI’s advertising policy is its consideration of where an advert sends the user.

The review isn’t limited to the wording of the ad. OpenAI also assesses the landing page and requires the destination to comply with its advertising policies.

This is particularly relevant to law firms.

A guide answering a common legal question may be entirely educational. But if that guide is hosted on a solicitor’s website, the surrounding site will naturally contain information about legal services, contact details, enquiry routes and links to relevant service pages.

For advertisers in the legal sector, this creates an area where the boundary between permitted legal education and restricted legal services can become less clear.

It’s something we’re continuing to monitor as the platform and its review processes develop.

Does this mean ChatGPT Ads aren’t relevant to law firms?

We don’t think law firms should write the channel off.

OpenAI is continuing to develop its advertising product, and policies can change as platforms mature, safeguards improve and new advertising categories are introduced.

There is also a wider reason for legal marketers to pay attention to what is happening; ChatGPT gives us another indication of how online behaviour is changing.

For years, much of legal digital marketing has been built around search intent. A prospective client searches for a service, Google provides a set of results and firms compete to appear at the point when that person is ready to take action.

That journey still matters enormously, and Google Search remains one of the strongest paid channels available to law firms.

But it is no longer the only way people research legal problems online.

Increasingly, people are asking AI tools questions, refining those questions and exploring a subject conversationally before visiting a firm’s website.

Advertising within those conversations could become an interesting way of reaching prospective clients earlier in their decision-making process, if and when legal services become eligible.

Should law firms invest in ChatGPT Ads now?

Based on the current restrictions, we wouldn’t recommend moving budget away from established advertising channels to fund a ChatGPT Ads campaign.

There are currently clearer opportunities elsewhere, particularly through Google Search where firms can reach people actively looking for legal support.

But we also don’t believe in waiting until a new marketing channel is fully established before taking the time to understand it.

Part of our role as a specialist legal marketing agency is to keep abreast of changes in digital behaviour, test new opportunities where appropriate and understand how they could affect our clients.

Sometimes that testing identifies an opportunity. Sometimes it tells us that a channel isn’t ready for a particular sector yet.

Both are useful.

For ChatGPT Ads, our view at the moment is to watch developments closely without getting carried away by the novelty of the platform.

There is a wider opportunity for law firms

Whether or not law firms can advertise directly within ChatGPT today, the growth of conversational search is already relevant to legal marketing.

People don’t always begin their journey by searching for the name of a legal service.

They ask questions.

What happens to the house when we divorce? How long does probate take? What searches do I need when buying a property? Can my landlord refuse to fix damp? Do I need a solicitor to make a Will?

These are the questions that can eventually lead to an instruction.

For law firms, producing useful content that answers them clearly has value well beyond a single marketing channel. It can support traditional SEO, contribute to visibility within AI-driven search and help prospective clients understand both their situation and the expertise available to them.

It also means that SEO, AEO, content and paid advertising are becoming increasingly connected. The platforms people use to find information are changing, and law firms need to consider how they remain visible throughout that journey.

What happens next?

ChatGPT Ads are still at an early stage, particularly from the perspective of regulated and professional services.

At present, OpenAI’s restrictions mean there is limited scope for law firms to use the platform for paid advertising. Our experience so far also suggests that firms shouldn’t assume educational content provides an easy route around those restrictions.

That may change as the platform develops.

We’ll continue to follow OpenAI’s advertising policies, test developments where appropriate and assess new opportunities based on what they can realistically offer law firms.

There is plenty of reason to be interested in advertising within AI platforms. There is less reason to divert marketing budget towards a new channel simply because it is new.

For now, the opportunity for law firms lies in understanding how people’s search and research behaviour is changing, making sure their wider digital strategy reflects that change, and being ready to take advantage of new channels when they become commercially viable.

Is your law firm ready for the next shift in digital marketing?

From AI search and AEO to established channels such as SEO and paid advertising, the way people find and research law firms continues to change.

At FireTap Legal, we help law firms make sense of those changes and focus their marketing investment where it can make a genuine difference. If you’d like to discuss your current digital strategy and where the opportunities lie, get in touch with our team.
