Three disciplines founders routinely confuse, what each actually buys you, how they should divide a budget at each stage, and the one thing none of them can fix.
Founders use these three words interchangeably and then wonder why the agency they hired is not doing the thing they wanted. They are different jobs, they produce different results on different timelines, and they should be bought differently. Here is the split.
Advertising is paid. You buy the space, you control the message, and it stops the moment you stop paying. Fast, measurable, expensive at scale, and trusted least by the audience because everyone knows you wrote it.
Public relations is earned. Someone else, a reporter, an analyst, a host, decides your story is worth telling and tells it in their words. Slow to build, cannot be fully controlled, trusted most because it came from a third party, and it keeps working after the fact.
Marketing is the whole system that turns attention into customers. It contains advertising and PR as channels, alongside product marketing, content, email, events, and everything that happens on your own website. If PR and advertising generate attention, marketing is what it lands on.
The confusion comes from treating them as substitutes. They are layers.
Advertising is good at volume and timing. You need ten thousand people to see something this week, in a specific place, with a specific offer. Nothing else does that. It is also the fastest way to test whether a message works, because you can change it tomorrow and measure the difference.
PR is good at credibility and durability. A profile in the outlet your buyers trust does something no ad can: it makes strangers believe you before they meet you. That single placement shows up in the sales deck, the investor update, the recruiting page, and the search results for your name for years. It also compounds. Reporters who covered you once cover you again.
Marketing is good at conversion. The landing page, the email sequence, the pricing page, the case study. This is where attention becomes revenue, and it is where most early-stage companies underinvest while overbuying the two above it.
Buying PR and expecting advertising outcomes. "We spent three months on PR and got two articles" is the most common complaint about the discipline, and it reflects a category error. PR is not a lead-generation channel with a weekly output. It builds the thing that makes every other channel convert better. Measure it by what changes in how people respond to you, not by clip count.
Buying advertising and expecting PR outcomes. Paid placement, sponsored content, and "guaranteed coverage" packages produce things that look like articles and carry none of the trust. Readers can tell. So can Google.
Skipping marketing entirely. Coverage lands, ads run, and the traffic arrives at a website that does not explain what you do or a signup flow that loses half of it. The attention was real. The system to catch it was not there.
Treating owned channels as an afterthought. Your newsletter, your social accounts, your own site. These are the only channels you fully control and the only ones that let earned coverage keep working after the news cycle moves on. A company with real owned reach is buying less advertising and getting more from every placement.
There is no universal ratio, but there is a pattern that holds across sectors.
Before product-market fit. Almost all marketing, in the narrow sense: talk to customers, fix the website, build the email list. Very little advertising, because you do not yet know what message converts. Selective PR only if you have a genuine story, because a weak launch teaches reporters to ignore the next one.
Finding fit, first real revenue. Advertising turns on, mostly for testing. PR turns on in earnest, because now there is proof to point to and a category to claim. Owned channels get built seriously.
Scaling. Advertising grows with the unit economics that justify it. PR shifts from announcements to thought leadership and category positioning. Marketing becomes a team. This is also when the three start contradicting each other if nobody holds one message across them, which is the argument for running communications from one desk.
Crisis, at any stage. Advertising goes quiet. PR does the work. Marketing makes sure the website says the right thing when everyone comes to check.
Attention amplifies what is already true. If the product is weak, advertising gets more people to discover that quickly, PR gets a reporter to say it publicly, and marketing gets it in front of the exact customers most likely to leave a review. Communications is not a substitute for having something worth communicating.
The founders who get the most out of all three are the ones who can answer, in one sentence, what they do and why it matters to the reader. That sentence is the input to the ad, the pitch, and the landing page alike. Write it first.
We are a PR firm, so you would expect us to argue for PR. The honest position is that PR is the discipline with the highest ceiling and the longest fuse, which makes it the one most often bought at the wrong time or measured the wrong way. Bought at the right time, run alongside owned channels you control, and landed on marketing that converts, it is the best money in the stack. That is roughly the shape of what we do.
