The problem

Why your site is
invisible on Google.

The 4 reasons your competitors are capturing your clients.

Invisible on Google

Your competitors appear first. Your potential clients never find you, even when searching for your services in your city.

Traffic in free fall

Your site exists, but nobody visits. No visitors = no contacts = no clients. The vicious cycle of the ghost site.

Exploding Ads budget

You pay Google Ads for every click, every month. As soon as you stop, visits drop to zero. Zero lasting asset.

Content without strategy

Pages created randomly, without targeted keywords, without structure. Google doesn't understand your site and doesn't rank it.

Frequently asked questions

SEO:
your questions, our answers.

How long does it take to see SEO results?

First ranking improvements appear in 4 to 8 weeks. Significant results (top 3 Google, notable traffic increase) typically materialize in 3 to 6 months, depending on keyword competition.

What's the difference between SEO and Google Ads?

Google Ads = immediate results but paid per click (as soon as you stop, you disappear). SEO = lasting, free results once ranking is achieved. Ideally, combine both at the start, then reduce Ads as SEO takes over.

How do you measure results?

Every month, you receive a detailed report with: rankings on your target keywords, organic traffic evolution, number of conversions (calls, forms, quote requests), and recommendations for the following month.

Does SEO work for my industry?

Yes. SEO works for all industries: tradespeople, professionals, e-commerce, B2B services. As long as your clients search for your services on Google, SEO is profitable. We analyze your market before starting to confirm.

Do I need to redo my site to improve SEO?

Not necessarily. We first optimize your existing site (structure, content, performance). If technical limitations block SEO, we offer a targeted redesign. Our website creation service is SEO-optimized from conception.

How much does SEO support cost?

Our SEO packages start at €290/month. The price depends on keyword competition, number of pages to optimize and your goals. Free initial audit and personalized quote within 24h.

Am I locked into a long contract?

No. Our contracts have no duration commitment. We recommend a minimum of 6 months for solid results, but you're free to stop at any time. Our clients stay because the results are there.

What happens if I'm not satisfied?

We adjust the strategy based on your feedback and data. If after 3 months the indicators aren't progressing, we completely rethink the approach at no extra cost. Our goal: measurable results, not promises.
