Marketing & tracking

Depending on your sector and market, a test budget of €800 to €1,500/month is already enough to gather meaningful data. Below that, automated bidding algorithms lack the volume to optimize properly.

Monthly package starting at €400/month for management (excluding ad spend), depending on the number of campaigns and desired optimization level. Free initial audit to assess potential.

Yes, provided it's well fed with quality audience signals and paired with clean GA4 tracking. Left on default settings, it often wastes budget on unqualified traffic.

Yes, and it's actually recommended: SEO and Google Ads reinforce each other (shared keyword data, brand presence). See my dedicated SEO page for more details.

Yes, completely: an event-based model rather than sessions-based, different conversion handling, a redesigned interface. A configuration simply carried over from the old Analytics is almost always incomplete for e-commerce.

Yes, via Google's Consent Mode v2: tracking adapts to the visitor's choice (accepted, refused, partial) without breaking data collection for those who consent, and without collecting information on those who refuse.

PrestaShop, Shopify, WooCommerce, WordPress or any custom stack, generally via Google Tag Manager to stay flexible without touching code for every change.

On a creation or redesign project, the setup is included. As a standalone service on an existing site: €400 to €900 depending on the complexity of the purchase funnel and the number of events to track.

No, quite the opposite: properly configured, it loads scripts asynchronously and avoids multiple blocking tags. A site with scattered hardcoded scripts is often slower than one managed by a clean GTM setup.

GTM centralizes everything in one place: a single management point, clear documentation, the ability to roll back. Hardcoding each pixel multiplies the risk of error and makes every change dependent on a developer.

Yes, it's actually one of the main benefits: GTM can make each tag's firing conditional on the consent given, via Google's Consent Mode v2, in connection with Axeptio, Didomi or any other consent management solution.

On a creation or redesign project, installation is included. On an existing site with migration of scattered tags: €500 to €1,200 depending on the number of scripts to centralize and the complexity of the triggers.

PrestaShop, Shopify, WooCommerce, or any catalog exported from a custom stack. Each CMS has its own modules or export methods, which I adapt to your specific needs.

The most common causes: missing or incorrect GTIN, mismatch between the price shown on the site and the one in the feed, non-compliant images (logo, watermark), a poorly chosen Google category. I diagnose and fix these errors as a priority.

Yes, that's the goal: the feed is connected directly to your CMS catalog, with a sync frequency (usually several times a day) so price, stock and availability always stay consistent with your site.

On a CMS with a native module (PrestaShop, Shopify, WooCommerce): €400 to €900. With advanced feed rules and fine segmentation for Performance Max: €900 to €2,000 depending on catalog size.

Less and less. With ad blockers, Safari's ITP and iOS restrictions, the Pixel alone misses 20 to 40% of conversion events. The server-side Conversions API compensates for this loss by sending data directly from your server.

Starting at €500-800/month to properly test several audiences and creatives. Below that, the algorithm lacks the data to optimize delivery effectively.

Monthly package starting at €400/month excluding ad spend, including Pixel/CAPI setup, campaign management and reporting. Free initial audit.

It depends on your product and target audience. Google Ads captures existing purchase intent; Meta Ads creates desire among audiences who weren't yet searching. Often, the two are complementary rather than exclusive.

Brevo is a French solution (data hosted in the EU), often with more favorable pricing for high volumes of transactional emails, and a natively integrated SMS module. Mailchimp remains relevant for certain specific advanced automation needs.

Basic installation and configuration (transactional emails + 2-3 automations): €600 to €1,500. Advanced segmentation and complex multi-step automations: €1,500 to €4,000.

Yes, and it's actually recommended for better deliverability and more polished design. The Brevo module intercepts PrestaShop's transactional emails and sends them through Brevo's infrastructure with your custom templates.

Yes, Brevo is a French company subject to GDPR by default, with data hosted in Europe. I set up double opt-in, unsubscribe preferences and mandatory legal notices on all your forms.

Mailchimp excels at advanced e-commerce automations and deep behavioral segmentation. Brevo is often more cost-effective for high volumes of transactional emails and offers native SMS. I advise based on your volume and specific needs.

CMS connection and basic automations: €600 to €1,500. Advanced segmentation, recurring editorial newsletters and systematic A/B testing: €1,500 to €4,000.

Yes, import of your contacts from another tool or a CSV file, with GDPR compliance verification (consent, opt-in source). Segmentation rebuilt if needed.

Yes, provided they're properly configured with your real sales data. A well-calibrated abandoned cart reminder typically recovers 5 to 10% of lost carts — one of the highest ROIs in digital marketing.
