The benefits of SEA

Why is SEA the most powerful growth engine for your business?

Paid referencing (SEA) is the most direct and measurable acquisition lever. Capture the intention to buy at the exact moment when your prospects are looking for your solutions.
Immediate results

Lead Generation and Sales: Get Immediate Results

Unlike SEO, which requires months, SEA generates qualified traffic as soon as your campaigns are put online. Each click comes from a user who is actively looking for your products or services. It is the fastest acquisition channel for generating leads and sales.
Guaranteed visibility

SERP dominance: Be visible where your customers are looking for you

Google Ads occupy the top 4 positions on the results page. Being present in SEA means guaranteeing your visibility on the strategic requests of your market, even in the face of competitors who are better positioned in SEO. You are in control of your presence.
Controlled ROI

Performance management: Control your costs with surgical precision

SEA offers total control over your investments. You define your budget, your bids, your target audiences. Every euro spent is trackable up to the conversion. We are constantly optimizing to maximize your ROAS (Return On Ad Spend) and reduce your CPA.

Frequently asked questions

FAQ Agence SEA: The answers to your questions about paid referencing

Answers to the most frequently asked questions about Google Ads, SEA and our support to maximize your advertising ROI.

How much advertising budget should you plan to start with Google 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.

What is the concrete difference between SEO and SEA?

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.

How long does it take to measure the return on investment (ROI)?

To choose your PR agency, evaluate several criteria:
1) Its sectoral expertise: does it know your market and its reference media?
2) Its network of journalists: can it put you in contact with key editorial offices?
3) Its methodology: does it offer an audit, a personalized strategy and clear reporting?
4) His references: ask for customer cases similar to yours.
5) Its price transparency: beware of promises of guaranteed results, PR also depends on current events.

Why is the Quality Score crucial for your savings?

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.

How are the management fees of a SEA agency structured?

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.

Is it possible to precisely target a geographic area or an audience?

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 indicators (KPIs) do you follow to measure performance?

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.

Do you also manage YouTube Ads and Display campaigns?

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.
