SEO = Search Engine Optimization = Natural referencing.

f you're thinking about setting up an SEO strategy for your business, one of the first things you'll consider is the cost. However, it is not easy to give a precise figure for these types of services. Indeed, the price of an SEO strategy can vary depending on many factors such as the depth of the strategy put in place, the experience of your provider and the time spent on execution.

That's why it is imperative to define the goals you want to achieve through natural referencing. In this article, we are going to analyze the average prices of an SEO strategy.

‍

What to define before starting an SEO strategy

Before starting to talk about prices, we must first define an essential element: your goals. Based on these objectives, your service provider will be able to define specifications and an adapted natural referencing strategy. Key questions to ask yourself:

• Do you want to generate more traffic?
• Convert more visitors into customers?
• Strengthen your reputation on your reference market?

In principle, a good provider will be able to ask you the right questions to determine your goals, understand your audience and identify your direct and indirect competitors.

Another fundamental element to take into account is the current state of your website. Check out our blog post to get an idea of the price of a new website.

What is the purpose of an SEO strategy in 2025?

In a nutshell: to be visible on search engines.

An SEO strategy has several advantages. The main objective of SEO is to attract more traffic to your site. The result is quite simple to measure: on a specific query, what is your position before and after launching your SEO strategy?

SEO is one of the most effective levers to improve your online visibility and attract qualified traffic to your website. Today, being first on Google is better than a shop window on Avenue Louise.

However, it's important to understand that SEO is a long-term strategy. It usually takes several months to start seeing the first results, and a monthly investment is needed to maintain and improve your positions.

The price of the 3 pillars of SEO

• Content creation (added value)
• The reputation of your site (netlinking)
• The technical configuration (performance)

Each pillar has its own strategies, prices, and components. Some companies use different providers for the various pillars. We are going to analyze the price together.

The price of an SEO audit

How much does an SEO audit of your website cost?  The cost of an SEO audit can vary between 0€ and 800€, depending on the size of your site and the complexity of the audit.

This analysis of your natural referencing makes it possible to identify the strengths and weaknesses of each of the pages of your website, their average position on search engines and those of your competitors. This is usually the first step in your SEO strategy.

The result can you expect? Complete report on your current positions, the keywords on which the pages of your site are positioned, the position of your competitors on their words, the number of incoming/outgoing links from your site and a technical analysis of each of the pages of your site.

‍

Pillar 1 - Content creation

The price of a keyword study

How much does a keyword study cost? The cost of a keyword study varies between €500 and €2,000 depending on the number of keywords to be positioned.

Good content is easy to define: it meets the needs of your users. So everything starts with understanding your target audience, their vocabulary and expectations. This research step will help define the keywords you should use. This step is often referred to as semantic field analysis. It must take into consideration many elements, including the use of voice searches and the difficulty in ranking for certain keywords (short and long tail).

The result you can expect: A list of keywords relevant to your business, the number of monthly searches, and the level of difficulty for positioning.

‍

Writing the content of your site

How much does content writing cost? The cost of writing content or copywriting varies between €65/h and €100/h.

If you manage this component yourself, beware: you cannot (entirely) delegate writing to artificial intelligence. Many parameters are important in writing: the choice of your titles (H1), keyword frequency, synonyms and broad terms. In principle, with a good keyword analysis, writing becomes easier. We recommend choosing a specific topic for each page. It's also important to update the content on your pages and blog posts regularly.

The result you can expect: Content optimized for SEO, with each page addressing a specific topic and incorporating the selected keywords.

‍

Writing blog posts

How much does it cost to write a blog post? The cost of writing a blog post varies between €300 and €600 depending on its complexity and the writer's experience.

A blog post doesn’t necessarily need to follow strict rules (keyword count, length, etc.). What matters most is that it clearly and accurately answers a user’s question. Your blog content must also stay up to date.

The result you can expect: A blog post that responds to a specific user need. Ideally, Google will rank your article well because it sees it as the best answer.

‍

Pillar 2 - the reputation of your site or backlinking

How much does a backlink strategy cost? The cost to obtain quality links varies between €30 for directory links and over €500 for premium links.

Some links are internal, pointing to other pages or articles on your site. These form your internal network. Others are external and directly impact your site's reputation.

Marketing agencies use paid tools to identify relevant backlink opportunities. Some links (to unreliable sites) will negatively affect your SEO, while others (to trusted sites) will improve it. Depending on your needs, an agency may acquire between 1 and 5 links per month, sometimes more. For very reputable sites (e.g. Le Monde), a permanent link may cost several thousand euros.

The result you can expect: A strengthened reputation. Pages referenced on other sites should improve their rankings on targeted keywords.

‍

Pillar 3 - The technical aspect: the performance of your site

How much does it cost to technically optimize your site? The cost of implementing technical recommendations ranges between €300 and €700, depending on your site's complexity and technical requirements.

This is often the hidden part of the iceberg, or the “backend”, but it’s one of the most important. Google’s robots regularly crawl websites, and there are techniques to make their work easier. This includes server setup, loading speed, URL structure, sitemap, meta descriptions, source code optimization, and more.

This is where specialists excel and amateurs struggle. It’s crucial to entrust this task to someone reliable who also keeps up with search engine updates (like Google’s E-E-A-T).

Generally, there are 3 levels of technical attention: errors, warnings, and recommendations. Your website’s performance must be constantly optimized.

The result you can expect: A technical score (or health rating) that aligns with your expectations and budget, presented in a performance report (monthly, quarterly, semi-annual or annual).

‍

Reporting and position monitoring

How much does reporting and position monitoring cost? In principle, this service is included in your SEO strategy. This is how your agency presents the results.

It is a key step in your strategy: understand what’s happening. Your agency will send you performance reports. Remember, it’s not your website that ranks, but your individual pages, and many factors are involved.

These reports should show which pages and keywords are generating traffic. Each one will include a section for position tracking, letting you compare your current ranking with previous periods and your competitors’ positions.

Reports are usually sent monthly, quarterly, or every six months.

In addition to showing the results of your efforts, reports reveal which strategies worked and which didn’t. With this data, your SEO expert can fine-tune your next actions by reinforcing winning strategies and seizing new opportunities.

The result you can expect: A detailed overview of your page rankings on Google, your progress over time, and a clear view of your website’s technical performance and actions taken.

‍

The secret to the success of a good strategy

Okay, it may sound a bit bold, but there really is a secret that too few businesses know. A strong SEO strategy works on all three pillars at the same time.

You must activate these three levers in parallel and on an ongoing basis.
