The number 1 B2B lever

Why is LinkedIn the No. 1 growth driver in 2026?

With more than one billion members and a highly qualified B2B audience, LinkedIn has become essential for generating leads and establishing its leadership.
Strategic visibility

Become Top of Mind and occupy the minds of your target prospects

LinkedIn is the only network where your B2B decision makers spend time every day. By regularly publishing high value-added content, you stay present in their news feed and become the natural reference when they need your expertise. That's the power of personal branding: turn your profile into an opportunity magnet.
Automated lead gen

Generate a constant flow of qualified leads without cold prospecting

No more ignored emails and unanswered calls. With a well-executed LinkedIn strategy, your prospects come to you naturally. Social selling allows you to create authentic conversations that lead to qualified appointments, without ever coming across as an pushy salesperson.
Employer brand

Boost your employer brand to attract top talent

LinkedIn is not only a sales channel: it is also your HR window. By embodying your values and corporate culture through your publications, you attract talent who share your vision. A visible and inspiring leader on LinkedIn significantly reduces recruitment costs.

Frequently asked questions

FAQ: Everything you need to know about business via LinkedIn

Answers to the most frequently asked questions about business development and lead generation via LinkedIn.

What is the difference between organic LinkedIn and LinkedIn Ads?

A press relations agency (or PR agency) is a service provider specialized in managing your relationships with the media. She develops your external communication strategy, writes your press content (press releases, press kits), identifies and contacts relevant journalists, organizes interviews and measures the impact obtained. Unlike an advertising agency, the objective is to obtain editorial coverage (not paid), perceived as more credible by the public.

How can I measure the ROI of my LinkedIn strategy in concrete terms?

An effective PR strategy is based on three fundamental pillars: 1) A clear positioning with differentiating messages that meet the expectations of journalists (the angle of contact). 2) Precise targeting of media and journalists relevant to your sector, with personalized contacts. 3) A regular approach to actions with an editorial calendar aligned with news and media channels. To these three pillars, a fourth is now added: SEO integration to capitalize on the backlinks generated.

Can you manage several LinkedIn profiles simultaneously (managers, salespeople)?

To choose your PR agency, evaluate several criteria:

How long does it take to see the first concrete results?

Competent press officers work in PR agencies or as freelancers. In Paris, the market is dense with agencies specialized by sector (tech, fashion, food, corporate...). In the regions (Lyon, Bordeaux, Nantes, Lille...), choose an agency that masters both national and regional media. At 425PPM, we operate throughout the country with a network of PQR (Regional Daily Press) contacts and local media in addition to the national media.

Do you have to have a Sales Navigator subscription to be successful?

The budget of a PR campaign varies according to several factors: the duration (one-time or long-term support), the extent of the objectives (product launch vs continuous visibility), and the services included (writing, media training, events...). On average, monthly support starts at around €3,000 excluding tax for a startup and can reach 5,000 to €10,000 excluding tax for a large-scale campaign. AVE (return in advertising equivalent) makes it possible to measure the ROI of this investment.

How do you manage the privacy and security of my account?

The fundamental difference is the control of the message. In advertising, you pay for a space (print, TV, digital) and control 100% of the content. In PR, you don't pay for media space: it's the journalist who decides whether to talk about you (or not) and who writes the article from his angle. This editorial character gives PR greater credibility: an article in Le Monde or a passage on BFM Business is perceived as a third-party validation, more reliable than an advertisement. On the other hand, the results are less predictable.

What is the average budget to invest for a LinkedIn agency?

The first results can appear as early as the first month for strong news (fundraising, major launch). However, a sustainable PR strategy generally requires 3 to 6 months to build solid relationships with journalists and get regular coverage. The SEO benefits (improvement of SEO thanks to mentions of your company) are visible after 3 to 6 additional months. We recommend a minimum commitment of 6 months for significant results.

Is it possible to completely delegate the management of my profile?
