Digital advertising & SEA: your immediate growth lever

Unlike SEO which takes time, paid campaigns (SEA) deliver results quickly. But their profitability depends on precise orchestration : targeting, creative, bid management, conversion tracking…

Without deep expertise, you risk:

Targeting the wrong audiences and burning through your budget
Overpaying for clicks against the competition
Failing to track your conversions properly (missing data, broken tracking)
Missing the AI optimisation opportunities

This illustration represents the multi-channel SEA campaigns run by Oli-via-net: Google Ads (Search, Display, YouTube), Meta Ads (Facebook, Instagram), LinkedIn Ads (B2B). The aim: to build coherent campaigns driven by data and artificial intelligence, to maximise immediate growth and advertising profitability.

Let’s hit your growth targets together

We work with companies across every sector: small businesses, mid-market, large accounts, startups…

An agency specialising in AI to optimise sales

AI: a powerful tool for optimising your campaigns

With artificial intelligence and machine learning, your campaigns do not merely run: they learn, adapt and improve continuously.

We connect your website and your CRM to feed these processes, and we build them in from the creation or redesign of your website.

AI analyses your historical data and predicts which campaigns, audiences and creatives will perform. It anticipates trends and seasonality before they hit your results.

Our algorithms adjust your bids in real time according to:

Time of day (morning against evening performance)
Day of the week (weekend against weekday)
Device (mobile, desktop, tablet)
Geographic location
Estimated probability of conversion

AI automatically identifies:

The most profitable audience segments
The optimal lookalikes of your best customers
The winning combinations (age + interest + behaviour)
The exclusions needed to avoid waste

Automatic writing of ad variants
Systematic A/B testing on every element (headlines, descriptions, CTAs)
Identification of the messages that convert best
Tone adapted to the audience being targeted

Our AI agents do not just compile figures. They produce insight:

“Your Facebook conversions fell 23% this week, most likely because of ad fatigue on your main audience. Recommendation: refresh the creative and widen the targeting.”

“Your Google Shopping campaign on product line X is returning a ROAS of 5.2 against an average of 2.1. Opportunity: increase the budget by 30%.”

You are notified instantly (email, Slack, WhatsApp) if:

A campaign overshoots its target budget
The conversion rate drops sharply
A competitor launches an advertising push
A major optimisation opportunity is detected

Frequently asked questions on digital advertising

Investing in digital advertising means making strategic trade-offs: what budget to allocate, which platform to favour, how to measure the return, and above all how to avoid burning budget with nothing to show for it.

At Oli-via-net we work to a rigorous method built on three pillars: complete transparency, precise tracking and continuous optimisation. Every euro spent has to produce a measurable return.

This FAQ answers the 18 most common questions on Google Ads, Meta Ads and LinkedIn Ads. It will help you understand how digital advertising actually works, identify the costly mistakes to avoid, and compare approaches so you can choose a partner who runs your campaigns as a genuine investment rather than blind spending.

Understanding digital advertising

Answer: A digital advertising campaign means running targeted ads on platforms such as Google Ads, Meta Ads (Facebook/Instagram) or LinkedIn Ads, according to your business objectives.

Each channel answers a specific moment in the customer journey:

Google Ads : capturing immediate purchase intent (active search)
Meta Ads : building awareness, working on discovery and retargeting
LinkedIn Ads : reaching B2B decision-makers with professional precision

Steering rests on concrete indicators: CPC (cost per click), CPA (cost per acquisition), ROAS (return on ad spend). The aim: turning every euro invested into a measurable result, not mere “visibility”.

Answer: SEO (Search Engine Optimisation, organic search) aims at free, durable visibility by ranking your site on strategic queries. It is a long-term investment that builds your brand’s authority.

SEA (Search Engine Advertising) buys immediate visibility through ad auctions. Results from the first days, but they stop the moment you cut the budget.

The winning strategy? Combine the two:

SEO stabilises your traffic and lowers acquisition cost over the long run
SEA accelerates growth, tests messages and captures immediate opportunities

At Oli-via-net we orchestrate both levers to maximise overall ROI. SEA funds the growth while SEO makes it last. Every interaction feeds the next, and performance improves continuously.

Answer: Because they launch campaigns with no clear structure, no reliable tracking and no continuous optimisation.

The 6 mistakes that cost the most:

Targeting that is too broad : you pay for unqualified clicks
Generic ads : low click-through rate, poor quality, high CPC
No search-term analysis : your ads trigger on irrelevant queries
Badly configured conversions : it becomes impossible to measure the real ROI
No active steering : budget drifts with no strategic adjustment
Weak or negative customer reviews

A complete audit identifies these leaks and turns advertising spend into a profitable investment. On average, we cut acquisition cost by 30 to 50% within the first 60 days after restructuring.

Platforms and strategies

Answer: It depends on your audience, your sales cycle and your objectives.

Google Ads :

Ideal for capturing immediate purchase intent
Works on Search (active queries) and Display (banners)
Fast ROI if the keywords are well chosen

Meta Ads (Facebook/Instagram):

Excellent for awareness, discovery and retargeting
Ultra-precise targeting by interest and behaviour
Cost per click often lower, but conversions less direct

LinkedIn Ads :

Essential in B2B for targeting decision-makers by role, sector and company size
Higher CPC (2 to 5 times Google), but highly qualified leads
Profitable if your average deal size justifies the acquisition cost

What we recommend: do not pick a single platform. A data-driven mix lets you follow the customer across the whole journey: discovery on Meta, search on Google, maturation on LinkedIn. It is this multi-channel approach that maximises ROAS, while also making your data more reliable.

Answer: Yes, provided you respect three rules:

Precise setup : role, company size, sector, location, seniority
A suitable message : LinkedIn is not Facebook — the tone has to be professional, factual, value-led
Rigorous tracking : connect LinkedIn to your CRM (HubSpot, Pipedrive, Salesforce) to track real ROI through to the sale

The main challenge: CPC is 2 to 5 times higher than elsewhere (often 5 to 15 €). But if your average deal exceeds 2,000 €, the platform becomes extremely profitable.

A concrete example: for a B2B consultancy we generated 47 qualified leads in 2 months on a 3,200 € budget. 8 became clients, for total revenue of 68,000 €. ROAS: ×21.

LinkedIn Ads does not work for everyone — but when it works, it is the most profitable B2B channel there is.

Answer: Smart Bidding uses Google’s or Meta’s artificial intelligence to adjust your bids automatically in real time, according to:

The user’s profile (history, device behaviour)
The context (time, location, competition)
The probability of conversion

Benefits:

CPA reduced by 20 to 40% on average
Considerable time saved (fewer manual adjustments)
Automatic identification of the most profitable segments

Critical limits:

Without clean tracking (GA4, Tag Manager, correctly configured conversions), the AI learns from bad data
You need at least 30 conversions a month for the algorithm to be effective
The first 2-3 weeks are a learning phase: costs can be unstable

Our method: we always start manually to validate the structure, then move progressively to Smart Bidding once conversions are stable and the tracking is impeccable.

Budgets, costs and profitability

Answer: Budget depends on your sector, the competition and your objectives. Here are the average thresholds we observe:

E-commerce:

Minimum: 800 to 1,000 €/month
Optimal: 1,500 to 3,000 €/month, to test several audiences and formats

B2B leads:

Minimum: 1,000 to 1,500 €/month
Optimal: 2,000 to 4,000 €/month, especially on LinkedIn

Local services (tradesperson, healthcare professional, coach):

Minimum: 500 to 800 €/month
Optimal: 1,000 to 1,500 €/month

Why these thresholds? Below them, the algorithm does not have enough data to learn. You risk spending without ever reaching profitability.

Our advice: better to concentrate your budget on one well-targeted channel than to scatter 300 € across three platforms. Concentration is what makes optimisation possible.

Answer: Immediate results (0 to 7 days):

First clicks as soon as it goes live
First conversions possible if the structure is solid

Learning phase (3 to 4 weeks):

The algorithm adjusts bids and identifies the most profitable audiences
Cost per acquisition stabilises progressively

Mature optimisation (2 to 3 months):

ROAS reaches its full potential
Campaigns become predictable and scalable

A warning: a badly structured campaign can run for months without ever becoming profitable. That is why the initial audit and the configuration are decisive.

Answer: ROAS (Return On Ad Spend) measures the revenue generated for every euro spent on advertising.

Formula: ROAS = revenue generated ÷ advertising spend

Example:

You spend 1,000 € on advertising
You generate 5,000 € of sales
ROAS = 5,000 ÷ 1,000 = 5.0 (you earn 5 € for every euro invested)

But ROAS is not enough on its own. You also need to track:

CPL (cost per lead): what does each sales contact cost?
CAC (customer acquisition cost): what does each new client cost?
LTV (lifetime value): what does a client bring in over their lifetime?

A concrete example:

a ROAS of 3.0 may look average
But if your gross margin is 70% and your customers reorder 4 times a year, it is excellent

At Oli-via-net we bring these indicators into a unified Looker Studio dashboard : you see in real time the profitability of every campaign, channel and segment.

Optimisation & performance tracking

Answer: Reliable tracking rests on a solid technical stack :

1. Google Tag Manager (GTM):

Centralises all your tracking tags (Google Ads, Meta Pixel, LinkedIn Insight Tag)
Lets you track custom events (add to basket, download, form completed)
Avoids cluttering your source code with dozens of scripts

2. Google Analytics 4 (GA4):

Analyses multi-channel conversions (cross-device attribution)
Measures the complete user journey
Identifies the pages that convert best

3. Looker Studio (formerly Data Studio):

Clear, automated and personalised reporting
Connects all your sources (Google Ads, Meta, LinkedIn, GA4, CRM)
Real-time visualisation: cost per click, conversion rate, ROI, ROAS over time

Without this stack, you are flying blind. We install this infrastructure from day one, so decisions rest on reliable data rather than intuition.

Answer: Weekly monitoring (non-negotiable):

Search-term analysis (adding negative keywords)
Bid adjustment on the performing segments
Testing new ads
Budget check (saturated or under-used)

Full monthly analysis:

Overall review: ROAS, CPA, conversion rate
Identification of new opportunities (new keywords, audiences, formats)
Adjustment of the overall strategy (budget reallocated between channels)

Quarterly optimisation:

Rebuilding the ad creative
Testing new platforms or formats (Performance Max, Demand Gen and so on)
Competitive analysis

A common mistake: leaving campaigns running for weeks with no intervention. The result: systematic waste and performance that stalls.

A high-performing campaign is steered every week, like a financial dashboard.

Answer : Primary indicators (the 3 most important):

Conversion rate : the share of visitors who become leads or clients
CPA (cost per acquisition) : what each conversion costs (lead or sale)
ROAS : return on ad spend (revenue generated ÷ advertising budget)

Secondary indicators (to refine):

CTR (click-through rate) : measures how attractive your ads are
CPC (cost per click) : tracks competitive pressure
Quality Score : Google’s rating, which directly affects your costs
Impression share : how much of the available voice you hold on your keywords
Frequency (Meta Ads): how many times the same person sees your ad

Beware of vanity metrics:

Impressions do not pay your bills
A high CTR with no conversion is useless
Only the indicators tied to acquisition cost and revenue really count

We configure automatic alerts on the critical indicators: if CPA passes the threshold, if ROAS drops, or if a campaign burns budget without converting, we step in immediately.

AI, automation and innovation

Answer: AI is transforming digital advertising across 4 key dimensions :

1. Bid optimisation:

Real-time adjustment based on probability of conversion
CPA reduced by 20 to 40% on average
Automatic identification of the most profitable segments

2. Predictive targeting:

Lookalike audiences based on your best customers
Behavioural scoring to prioritise hot prospects
Automatic exclusion of unprofitable profiles

3. Generating and testing ad creative:

Performance Max (Google) generates ad variants automatically
A/B testing at scale (headlines, descriptions, visuals)
Identification of the messages that convert best

4. Forecasts and alerts:

Anomaly detection (cost spike, drop in conversions)
Prediction of the budget needed to hit your objectives
Automatic optimisation recommendations

The result: steering that is more precise, faster and more profitable. But AI only performs if it is fed with clean, complete data (tracking, CRM, conversion history).

Answer: Yes, but with strategic supervision.

What can be automated:

Product feed updates (e-commerce)
Bid adjustment according to predefined rules
Synchronisation between the ad platforms and your CRM
Alerts when budget is overshot or performance drops
Generating weekly reports

Tools we use:

Google Ads scripts : for complex automatic adjustments
n8n / Make : to connect your tools (CRM, GA4, Sheets, Slack)
Zapier : for simple automations between applications

What has to stay human:

The overall strategy (which channels, which budgets, which objectives)
Creativity (messaging, storytelling, brand tone)
Critical analysis (correlation against causation, market context)
Trade-off decisions (budget reallocation, launching new formats)

Our approach: automation executes, humans decide. We automate everything that can be automated, to free up time for strategic analysis and creative optimisation.

Answer : No, but it can improve them considerably.

What AI does well:

Generating headline and description variants based on your best-performing ads
Testing dozens of combinations automatically (A/B testing at scale)
Identifying the wording that produces the best click-through and conversion rates
Adapting the message in real time to the context (device, location, time)

What AI does not do (yet):

Understand emotion and cultural context
Tell a coherent brand story
Match the tone to your unique positioning
Create a disruptive message that stands out

The winning combination: human creativity + AI optimisation

At Oli-via-net we create the distinctive concepts and messages, then use AI to:

Test 20 variants of the same concept
Identify the segments where each message works best
Automate delivery of the right message to the right person at the right moment

AI does not replace creative strategy — it deploys it at scale, with precision.

Support, reliability & transparency

Answer: Because a bad setup often costs more than an agency’s fees.

What an experienced agency brings:

A solid structure from the start:

An optimised campaign architecture
Impeccable tracking (GTM, GA4, conversions)
Precise targeting and negative keywords

Technical and strategic expertise:

Knowledge of the platforms’ latest changes
Sector benchmarks (so you know whether your performance is good or bad)
Access to professional tools (Semrush, Optmyzr, advanced Looker Studio, Majestic, ChatGPT in professional mode and more)

An ROI mindset, not a spending one:

Every euro has to be justifiable
Continuous optimisation: 30 to 50% CPA reduction on average
Dynamic budget reallocation towards what works

An enormous amount of time saved:

You focus on your core business
The agency steers, tests, adjusts and reports — every week

A concrete example: a client had been running his own Google Ads campaigns for 18 months on a budget of 1,200 €/month. Average CPA: 180 €.

After a complete restructuring and 60 days of optimisation: CPA at 78 € (- 57%). Same budget, but 2.3 times more conversions.

Answer: Results stop almost immediately.

SEA (paid advertising) delivers instant but not durable visibility :

You stop the budget → your ads disappear
Your traffic falls sharply (sometimes by 60 to 80% if you depended on SEA alone)
Your leads and sales collapse

That is why an SEO + SEA mix is the winning strategy:

SEO builds durable, free visibility (after the initial investment). It is your stable traffic base.
SEA brings immediate traffic, tests messages, captures seasonal opportunities and accelerates growth.

What we recommend:

Use SEA to fund fast growth
Reinvest part of the profit into SEO and AI search, to reduce your dependence on paid over time
Keep a permanent SEA budget on your most profitable campaigns

The long-term goal: reducing SEA from 80% to 40-50% of your total traffic, while maintaining — or even increasing — your conversion volumes through SEO.

Answer: A good agency must be able to justify every euro spent.

The 7 criteria for assessing your agency:

Transparent, complete reporting:
- Real acquisition cost (not just clicks or impressions)
- Conversions measured through to the sale (not just forms filled in)
- ROAS month by month
Direct access to your advertising accounts:
- You must own your Google Ads, Meta Ads and LinkedIn Ads accounts
- You must be able to see the data in real time
- Be wary of agencies that “keep the keys”
A detailed list of the optimisations carried out:
- What adjustments were made each week?
- What tests were launched?
- What strategic decisions were taken, and why?
Constant improvement in ROI:
- A good agency should cut your CPA by 20 to 40% in the first 90 days
- ROAS should improve quarter after quarter
- Performance should be compared against sector benchmarks
Responsiveness and proactive communication:
- A reply within 12 hours at most
- Immediate alerts if something goes wrong (cost spike, drop in conversions)
- Regular optimisation proposals (not passive waiting)
No opaque contract or abusive commitment:
- The terms must be clear (fees, duration, notice period)
- You must be able to leave with your data and your accounts
Strategic recommendations beyond execution:
- A good agency challenges your offer, your site and your conversion funnel
- It does not just “keep the campaigns running”

At Oli-via-net you get:

A Looker Studio dashboard updated in real time
Detailed monthly reporting with analysis and recommendations
Full administrator access to all your advertising accounts
A monthly strategic review meeting

If your current agency does not meet these criteria, it may be time to reconsider the partnership.
