The differences between public relations and marketing lie mainly in their objectives, audiences, channels and the way results are measured: while PR aims to build trust, credibility and relationships with an organisation’s different audiences, marketing is primarily focused on generating demand and turning that demand into commercial opportunities and sales.
That does not mean they are opposing disciplines.
On the contrary. Public relations and marketing work best when they are coordinated. A PR strategy can help a company become known, respected and regarded as a trusted source, while marketing can turn that awareness and trust into traffic, leads and customers.
The key is understanding the role of each discipline, where they overlap and what a company actually needs at any given moment.
What is the difference between public relations and marketing?
The short answer is simple:
Public relations builds reputation, credibility and relationships. Marketing creates and communicates value to generate demand and support commercial results.
However, this definition needs some nuance.
PR does not work only with journalists, nor is marketing limited to advertising.
Public relations can target customers, employees, investors, media, institutions, associations, partners and communities. Marketing, meanwhile, covers activities as varied as market research, positioning, product, pricing, distribution, SEO, digital advertising, email marketing, content and demand generation.
That is why the best way to understand their differences is to compare them directly.
Public relations vs marketing: key differences
| Aspect | Public Relations | Marketing |
|---|---|---|
| Primary objective | Build trust, credibility and reputation | Generate demand, leads, customers and growth |
| Audiences | Media, customers, employees, investors, institutions, partners and society | Mainly current and potential customers |
| Relationship with media | Predominantly earned media, together with owned channels | Predominantly owned and paid channels |
| Control over the message | Lower when journalists and third parties are involved | High in campaigns and channels controlled by the company |
| Focus | Relationships, perception and legitimacy | Market, customer, demand and conversion |
| Typical time horizon | Medium and long term | Short, medium and long term depending on the strategy |
| Tactics | Media relations, thought leadership, crisis communication, events, stakeholders | SEO, advertising, email, automation, CRO, content |
| KPIs | Share of voice, coverage, messaging, perception, branded search | Leads, conversions, CPA, ROAS, revenue |
| Primary outcome | Trust and authority | Commercial action and growth |
This distinction is useful, but it should not be interpreted as an absolute boundary.
A public relations campaign can generate sales. A marketing strategy can significantly strengthen a brand. And many activities today, particularly in the digital environment, generate results for both disciplines.
What are public relations?
Public relations is the set of strategies and actions designed to build and maintain mutually beneficial relationships between an organisation and its different audiences.
Its scope is therefore much broader than simply securing media coverage.
Common PR functions include:
- Relations with journalists and media outlets.
- Corporate communications.
- Reputation management.
- Crisis communication.
- Thought leadership and spokesperson positioning.
- Stakeholder relations.
- Internal communications.
- Events.
- Institutional communication.
- Digital PR.
- Development of corporate narratives and messaging.
A company can use public relations to increase awareness, but the real value appears when that visibility generates credibility.
It is not the same for a company to claim that it is an expert in its sector as it is for journalists, analysts, associations or independent third parties to recognise it as a relevant source.

What is marketing?
Marketing includes the activities, processes and strategies used to understand the market, create a value proposition and ensure that products or services reach the right audiences.
It is a much broader concept than advertising.
A marketing strategy may include:
- Market research.
- Segmentation.
- Positioning.
- Product strategy.
- Pricing strategy.
- SEO.
- Search advertising.
- Social media advertising.
- Email marketing.
- Content marketing.
- Automation.
- Demand generation.
- Lead nurturing.
- Conversion optimisation.
- Loyalty programmes.
While public relations focuses especially on how an organisation is perceived and the relationships it maintains, marketing focuses especially on what value it offers, who it targets and how it turns interest into action.
7 differences between public relations and marketing
1. Different objectives
The most obvious difference lies in the primary objective.
Public relations aims to build:
trust + reputation + legitimacy + relationships.
Marketing aims to generate:
interest + demand + conversion + growth.
Imagine an unknown technology company entering the Spanish market.
The PR team might work to make specialised journalists aware of the company, position its executives as experts and generate editorial coverage.
The marketing team might simultaneously work on SEO, Google Ads, LinkedIn Ads and landing pages to generate commercial opportunities.
Both are pursuing growth, but they reach it through different routes.
2. They do not target exactly the same audiences
Marketing works primarily with the market and customers.
For example:
- Potential customers.
- Users.
- Buyers.
- Existing customers.
- Commercial influencers.
Public relations expands that map considerably:
- Journalists.
- Editors.
- Employees.
- Investors.
- Institutions.
- Associations.
- Partners.
- Opinion leaders.
- Communities.
- Customers.
An audience can have a major influence on a company without ever buying its product.
That is one of the reasons why PR should not be reduced to a marketing tool.
3. Control over the message Is different
When a company publishes a Google Ads campaign, it controls the message, creative, landing page, budget and call to action.
When a journalist decides to write about a company, they retain editorial independence.
The PR agency or department can provide information, sources, interviews, data or context.
But it does not buy or control the editorial outcome.
That lower level of control is precisely one of the reasons why earned coverage can have particular value as a credibility signal.
This difference becomes even more important when comparing public relations and advertising. We explain it specifically in our article on the differences between public relations and advertising.
4. They use different channels
PR frequently works through:
- Media outlets.
- Direct relationships with journalists.
- Interviews.
- Opinion pieces.
- Reports.
- Events.
- Conferences.
- Associations.
- Corporate communication.
- Owned channels.
- Social media.
Marketing can work through:
- Search engines.
- Digital advertising.
- Email.
- CRM.
- Landing pages.
- Social media.
- Websites.
- E-commerce.
- Marketing automation.
- Content marketing.
- Affiliate programmes.
Some channels appear on both lists.
That overlap does not mean the disciplines are identical.
What changes is the role of the channel within the strategy.
LinkedIn can be used by marketing to generate a lead and by PR to strengthen a CEO’s positioning as an expert.
5. Success is measured differently
If the objective of a campaign is to sell, it makes sense to measure:
- Leads.
- Cost per acquisition.
- Conversions.
- ROAS.
- Sales.
- Customer Lifetime Value.
If the objective is reputational, other metrics become more important:
- Quality of coverage.
- Share of voice.
- Message penetration.
- Presence in priority media.
- Sentiment and context.
- Branded search.
- Spokesperson visibility.
- Stakeholder perception.
- Referral traffic.
- Results linked to communication objectives.
This does not mean PR should not be connected to business outcomes.
It means that not every reputational result can be evaluated using the same metric as a performance marketing campaign.
6. The time horizon is usually different
Certain marketing activities can begin producing results practically from day one.
A Google Ads campaign, for example, can generate traffic and conversions from the moment it is activated.
Building reputation works differently.
Getting journalists to know a company, developing relationships, establishing spokespeople and building credibility requires consistency over time.
Public relations tends to accumulate value.
One interview makes the next one easier. A reliable source receives calls from journalists again. A recognised spokesperson is more likely to be consulted in the future.
That is why consistency is particularly important in PR.
7. The commercial message has a different role
Marketing can make a direct call to action:
Request a demo.
Buy now.
Book a consultation.
Download the catalogue.
A public relations activity normally requires a different approach.
A journalist does not want to publish a sales pitch written by a company. They need information that is relevant to their audience.
That is why PR works around:
- Newsworthiness.
- Context.
- Trends.
- Data.
- Expert opinion.
- Industry relevance.
- Social or business impact.
The corporate message is still present, but it has to become a story that provides value beyond the brand itself.
Public relations and marketing: where they overlap
The boundary between the two disciplines has become considerably more fluid in the digital environment.
Digital PR and SEO
A strong digital PR campaign can generate brand mentions, editorial coverage and links from relevant media outlets and websites.
These results can increase visibility and traffic while also contributing to a company’s SEO ecosystem.
PR does not replace an SEO strategy.
But it can generate authority signals that an SEO team would struggle to achieve through owned content alone.
Thought leadership and demand generation
Positioning an executive as an expert may initially seem like a reputational objective.
But it can also have commercial consequences.
A potential B2B customer might discover the executive in an interview, then research the company, visit its website and ultimately become a commercial opportunity.
PR starts the journey.
Marketing can help convert it.
Content
Marketing and PR can both use content, but not always for the same objective.
An SEO guide may be designed to capture existing demand.
An opinion article signed by a CEO may be designed to build authority.
A proprietary report can serve both purposes.
That is why it is useful for communications and marketing teams to share calendars, messaging and assets.
Social media
Social media is another area of overlap.
It can be used for paid campaigns, lead generation and conversion.
It can also amplify media coverage, strengthen thought leadership, manage reputational conversations and communicate directly with stakeholders.
The channel is the same.
The objective can be completely different.
Example: an international technology company enters Spain
Imagine a US B2B company that wants to start operating in Spain.
It has a strong product and recognition in its home market, but practically nobody knows it in Spain.
What marketing would do
Marketing could work on:
SEO: building visibility for relevant commercial searches.
Google Ads: capturing existing demand.
LinkedIn Ads: reaching specific professional profiles.
Landing pages: explaining the local value proposition.
Email: nurturing commercial opportunities.
CRM: organising and measuring the funnel.
What Public Relations would do
PR could work on:
Positioning adaptation: turning the global narrative into a message that is relevant to Spain.
Media relations: introducing the company to business, technology and sector-specific journalists.
Thought leadership: positioning executives and specialists as sources.
News: identifying milestones with genuine journalistic interest.
Events: connecting with media, partners and stakeholders.
Credibility: securing external validation in the new market.
For international companies, this local adaptation is especially important. A global strategy should not simply be translated. It must be adapted to how the Spanish media ecosystem actually works.
The combined result
A person might:
- Discover the company in an article in a specialist publication.
- Search for the brand on Google.
- Visit a landing page.
- Find other articles and interviews.
- Download a resource.
- Enter a commercial nurture sequence.
- Request a demo.
Did Marketing or Public Relations generate that opportunity?
Both.
Trying to attribute all the credit to a single discipline ignores how B2B decision-making works today.
What does your company need: marketing, public Relations or both?
It depends on the problem you need to solve.
| Situation | Priority |
|---|---|
| Nobody knows our company | PR + Marketing |
| We need credibility in a new market | PR |
| We need leads immediately | Marketing |
| We have a reputational problem | PR |
| We want to position the CEO as a recognised expert | PR |
| We want to increase landing page conversions | Marketing |
| We are launching a strategic product | PR + Marketing |
| We want to generate long-term B2B demand | PR + Marketing |
| We are entering Spain | PR + Marketing |
| There is a crisis | PR / Crisis Communication |
In most mature companies, the question should not be whether to choose marketing or public relations.
The right question is:
What should each discipline do, and how should they be coordinated?
How should marketing and public relations work together?
Collaboration starts before a campaign is published.
Both teams should share:
Business objectives.
What does the organisation actually want to achieve?
Audiences.
Who do we need to influence, and why?
Positioning.
How do we want the market to understand our proposition?
Messaging.
Which concepts should appear consistently?
Calendar.
What launches, research, events or milestones are planned?
Content.
Which assets can be reused across different channels?
Measurement.
Which signals will show that we are making progress?
For example, if PR secures a relevant interview with an executive, Marketing can amplify it on LinkedIn, include it in a newsletter, use it as proof of authority on a landing page or incorporate it into commercial activity.
Similarly, data from SEO, PPC campaigns or customer searches can reveal topics with existing interest and generate ideas for communication and thought leadership.
Is a PR Agency the same as a marketing agency?
No.
Although some agencies offer services in both disciplines, an agency specialising in public relations focuses its expertise primarily on reputation, media relations, corporate communication, content, spokespeople, stakeholders and the management of sensitive situations.
A marketing agency is usually more focused on acquisition, campaigns, SEO, paid media, automation, conversion and demand generation.
Before hiring an agency, it is useful to start with the problem you want to solve.
If you need to strengthen credibility, enter a new market, secure editorial coverage or build relationships with journalists, you need genuine public relations capabilities.
In our guide to the benefits of hiring a public relations agency, we explain in greater detail what a specialist agency can contribute.
Frequently asked questions about public relations and marketing
What is the main difference between public relations and marketing?
Is public relations part of marketing?
It depends on the structure of each organisation. In some companies, PR sits within Marketing; in others, it forms part of Corporate Communications or operates as an independent function. Strategically, it is useful to distinguish their objectives and responsibilities even when the two areas work closely together.
Are public relations and advertising the same thing?
What are public relations in marketing?
Which Is better, marketing or public relations?
Can PR generate sales?
Should marketing and public relations use the same messages?
Public relations and marketing do not compete: they complement each other
The differences between public relations and marketing are important enough to treat them as separate disciplines, but that does not mean they should work in isolation.
Marketing helps organisations understand markets, generate demand and convert opportunities.
Public relations helps build the trust, reputation and legitimacy that make an organisation worth listening to and considering.
When both disciplines share strategy, messaging and objectives, the result can be much more powerful.
A commercial campaign works better when the market already knows and trusts the company.
And reputation creates more value when there is a strategy capable of turning that trust into opportunities.
At Finzel PR, we help national and international companies build that part of the equation: credibility, visibility, media relations and reputation in Spain and Portugal.
