You’ve just raised funds. You’re launching a new product. You want your name to circulate in the right media.

‍

You have two options: paying to appear or convincing to be mentioned.

This is where it all comes down to it. PR and advertising share the same goal: visibility. But they don't take the same path. And for a B2B tech startup leader, confusing the two can be costly, in both time and budget.

‍

Here is what you need to know before you decide.

‍

The fundamentals: earned media vs. paid media

The basic distinction in marketing is based on three types of media:

• Paid media : you buy advertising space. You control the message, the timing, and the medium.
• Owned media : your own channels (website, blog, newsletter, social media).
• Earned media : third parties talking about you without being paid to do so.

‍

Public relations fall under the earned media category.

‍

A journalist from Le Monde, TechCrunch, or L'Usine Digitale mentions your company in an article? That's earned media. It's not disguised advertising. It's independent editorial validation.

Advertising, by definition, is paid media. You buy a banner, a space, or a sponsored spot. The message is yours. The space is rented.

‍

These two approaches are in different leagues when it comes to credibility, cost, and longevity.

‍

What advertising can (and cannot) do for you

What advertising does well

Advertising has undeniable strengths:

• Total control : you choose the message, the visuals, the tone, and the timing.
• Speed : a campaign can be launched in a few days. Results are immediate and measurable.
• Precise targeting : Google Ads, LinkedIn Ads, Meta (target by industry, job title, geography, or intent).
• Scalability : increase your budget, increase your visibility. It’s a linear mechanism.

‍

For a launch campaign with a tight deadline, or to generate leads quickly, advertising is an effective tool.

‍

What ads can't do

Where advertising hits its limits:

• It stops the moment you cut the budget. No money spent, no exposure. It’s a faucet, not an investment.
• It doesn't build editorial credibility. Savvy B2B prospects can tell the difference between a sponsored post and an in-depth article in a leading publication.
• The cost per impression keeps rising. In B2B tech, the CPC on LinkedIn can exceed €10–15 depending on the segment. When targeting decision-makers, budgets skyrocket quickly.
• It generates distrust. B2B buyers are overexposed to advertising messages. Ad fatigue is real.

‍

In short: advertising buys attention. It does not buy trust.

‍

What PR offers that advertising can't buy

Journalistic credibility

When a journalist chooses to cover your company, it isn't because you paid them. It's because your story is deemed relevant to their readers. That is the true power of public relations : validation comes from an independent third party.

And in a B2B context, where decision cycles are long and purchases are carefully considered, this credibility is a significant trust accelerator. A study cited by Engage PR highlights that earned media is the most credible form of content in the eyes of B2B buyers, far ahead of advertising.

‍

The lasting impact of coverage

A press article doesn't disappear when you cut a budget. It stays online. It is indexed by Google. It can be found six months or two years later by a prospect doing their research. It is a durable asset, not a recurring expense. An ad placement, on the other hand, ceases to exist as soon as the campaign ends

‍

The cost per placement

Public relations requires an investment in time and support: a well-crafted press kit , a targeted press release , and in-depth work with journalists.

But the cost per piece of coverage obtained is often much lower than that of an advertising campaign with equivalent visibility.

‍

A mention in Les Echos or a leading tech media outlet is worth several thousand euros in advertising equivalent. Obtained through a structured PR strategy, it represents a fraction of that cost.

‍

SEO and long-term visibility

Press coverage generates quality backlinks from authoritative domains. This signal is invaluable for your SEO. Advertising, on the other hand, provides no direct SEO benefits.

‍

Comparison table: PR vs. advertising

‍

‍

Should you choose one? Or combine both?

The real answer is: it depends on your growth stage.

‍

In the launch or fundraising phase

Credibility is your number one challenge. Investors look for signs of legitimacy. Potential partners check who is talking about you. Prospective clients Google your name before signing.

Prioritize media relations. Building a lasting editorial presence is more strategic than buying fleeting visibility.

‍

In the commercial acceleration phase

You already have brand awareness. You want to generate leads in a predictable and scalable way.

Advertising becomes relevant as a complement. It can amplify PR coverage (boosting an article with paid social), target specific accounts, or cover segments that media outlets don't reach.

‍

The ideal combination

The two levers reinforce each other:

• PR legitimizes : it builds your credibility and industry authority.
• Advertising amplifies : it distributes that credibility to targeted audiences.

‍

Using advertising on a well-positioned press article, rather than on purely promotional content, means combining the advantages of both approaches.

‍

In summary

Public relations and advertising are not competitors. They serve different needs.

• Advertising buys visibility. It is fast, controllable, and measurable. However, it stops when the budget runs out and does not generate lasting credibility.
• Public relations build authority. They take longer to deploy but produce lasting, credible results that are beneficial for SEO.

‍

For a B2B tech startup looking to establish its market legitimacy, public relations is generally the priority lever, especially in the early stages of development.

Advertising can follow later as an amplifier, not a substitute.
