📌 Key takeaways

  • Paid search (SEA) can put you at the top of Google as soon as a campaign launches, whereas SEO typically takes three to six months.
  • Average cost per click (CPC) in France ranges from €0.50 to €5, depending on the sector (WordStream, 2024).
  • SEO and paid search complement one another: paid campaigns cover the short term, while SEO builds long-term visibility.
  • A well-structured Google Ads campaign generates an average €2 in revenue for every €1 invested (Google Economic Impact, 2024).
  • Your website quality affects your Google Ads Quality Score; a slow website can drive your CPC sharply upwards.

What is paid search?

Paid search, also known as SEA (Search Engine Advertising), is the practice of buying advertising space on search engines so that a website appears at the top of results for selected keywords. Unlike SEO, visibility is immediate and directly linked to the advertising budget.

Google accounts for more than 91% of searches in France (source: Statista, 2024), making Google Ads the dominant platform for paid-search strategies in the country. More than 8.5 billion searches are processed worldwide every day, equivalent to 63,000 per second (source: Google, 2024). For an SME that has just launched or redesigned its website, paid search offers a fast way to capture some of this traffic, provided that budget and strategy are carefully managed. This article explains how paid search works, what it really costs and how to use it intelligently alongside a sound organic search strategy.

How to create your first Google Ads campaign in five steps

  1. 1

    Étape 1

    Define your campaign objective

    First, be specific about the result you want: website traffic, phone calls, quote requests or online sales. Google Ads adjusts its bidding algorithms to the selected objective. A lead-generation campaign is not configured in the same way as a brand-awareness campaign. Choosing the wrong objective is one of the most common causes of wasted spend.

  2. 2

    Étape 2

    Choose your keywords carefully

    Use Google's Keyword Planner to identify relevant keywords, their search volumes and estimated CPCs. Prioritise precise, long-tail phrases with clear intent, such as ‘website redesign agency price’ rather than ‘website redesign’. Add negative keywords from the outset to prevent irrelevant clicks; this is where much wasted budget originates.

  3. 3

    Étape 3

    Write ads that convert

    Each ad includes three headlines of up to 30 characters and two descriptions of up to 90 characters. The main keyword should appear in the first headline. Enable ad assets such as sitelinks, a phone number and location details to increase click-through rate at no extra cost. Google rewards relevant ads with a stronger Quality Score and therefore a lower CPC.

  4. 4

    Étape 4

    Set your budget and bidding strategy

    For an SME, begin with a daily budget of €10–€30, then adjust it according to results. When starting out, a Maximise Conversions strategy with a limited budget can perform well. Avoid manual CPC if you have no historical data; Google's algorithm learns more quickly from live data than you can optimise manually.

  5. 5

    Étape 5

    Analyse and optimise the results

    After two to four weeks, analyse click-through rate (CTR), cost per conversion and Quality Score. A search-campaign CTR below 2% suggests that the ad needs work. A Quality Score below 5/10 indicates that the landing page is poorly aligned with the keyword, which can send CPC sharply upwards. Continuous optimisation separates a profitable campaign from a wasted budget.

Three mistakes that can drain your paid-search budget

  • Targeting keywords that are too broad: ‘website’ may cost €5–€10 per click for poorly qualified traffic. Prefer long-tail phrases with precise purchase intent.
  • Neglecting negative keywords: without an exclusion list, Google may show your ads for searches unrelated to your offer, making you pay for useless clicks from day one.
  • Sending traffic to the homepage: according to Unbounce (2024), a dedicated landing page aligned with the ad can increase conversion rate by a factor of three to five.

How much does paid search cost?

Paid search operates on a cost-per-click (CPC) model: you pay only when someone clicks your ad. The amount depends on competition for the keyword and your Quality Score. In France, WordStream (2024) places the average CPC between €0.50 and €5 in most sectors, although it can exceed €10–€15 for highly competitive terms in fields such as law, finance or healthcare.

An SME starting out should allow a minimum monthly budget of €300–€800 to gather useful Google Ads data. Below that level, the algorithm may lack enough data to optimise bids. Consider a practical example: an IT services provider with a €500 monthly budget focused on precise phrases such as ‘IT support Lyon’ and ‘IT support for SMEs’ could generate 80–150 qualified clicks. With a 5–10% conversion rate on a strong landing page, that represents four to 15 enquiries a month and a cost per lead of €33–€125, depending on landing-page quality and targeting. To manage profitability, measure your overall customer acquisition cost, not CPC alone.

The total cost of paid search may also include campaign management. If you entrust your account to a Google Ads agency, allow an additional €300–€800 a month, depending on campaign complexity. Agencies generally charge 10–15% of managed spend, subject to a fixed monthly minimum. Below a total budget of €1,000 a month for media and management combined, running the account in-house may be more cost-effective.

Before paid search

  • Website invisible for competitive, high-intent keywords
  • Traffic dependent on referrals and social media
  • No measurable return on marketing investment
  • No quick way to test new offers or messages

After launching a structured paid-search campaign

  • Immediate visibility for high-intent keywords from day one
  • Targeted, measurable traffic with precise source data
  • Known cost per lead that can be optimised in real time
  • Ability to test messages and offers within days

The three types of search visibility to understand

Online visibility can be divided into three complementary approaches, each with distinct mechanics and use cases. Understanding the differences helps you allocate your marketing budget accurately.

1. SEO: organic search

SEO (Search Engine Optimisation) aims to improve a website's position in Google's organic results without paying for each click. It relies on technical website optimisation, content quality and external links, or backlinks. Results take three to six months, but can endure over time. SEO is the long-term foundation of any digital visibility strategy and, according to Ahrefs (2024), pages in first position on Google receive an average 27.6% of all clicks for the query.

2. SEA: paid search

SEA (Search Engine Advertising) involves buying advertising space on search engines. Google Ads is the dominant platform in France. Ads appear immediately above organic results with an ‘Ad’ label, and you pay only when somebody clicks. Paid search is well suited to launches, seasonal campaigns and highly competitive keywords for which SEO would take too long to deliver results.

3. SMO: social media visibility

SMO (Social Media Optimisation) covers visibility gained through social networks, whether organically through posts and engagement or through paid advertising such as Facebook Ads and LinkedIn Ads. SMO does not replace SEO or paid search on Google, but complements the overall strategy, particularly when you need to reach audiences that are not yet actively searching for your offer. For some B2B SME sectors, LinkedIn Ads may be more relevant than Google Ads.
