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, on two conditions: feed it good information about your customers, and measure sales reliably with GA4 (Google's statistics tool). On default settings, it often wastes budget on visitors who never buy.

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: GA4 counts visitor actions (page views, purchases) where the old version mostly counted visits, handles conversions differently, with a redesigned interface. A configuration simply carried over from the old Analytics is almost always incomplete for an online store.

Yes, thanks to Google's Consent Mode v2: measurement adapts to each visitor's choice (accepted, refused, partial). Data is still collected for those who consent, and nothing is collected on those who refuse.

PrestaShop, Shopify, WooCommerce, WordPress or any custom site. Generally via Google Tag Manager, the tool that centralizes measurement scripts: changes then need no edits to the site's code.

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 journey and the number of actions to measure (purchases, add-to-carts, forms and so on).

No, quite the opposite: properly configured, it loads measurement tools in the background, without delaying page display. A site where scripts have been added by hand here and there is often slower than one where everything goes through a well-kept Google Tag Manager.

Google Tag Manager centralizes everything in one place: a single management point, clear documentation, the ability to roll back. Adding each tool directly into the code multiplies the risk of error and makes the slightest change dependent on a developer.

Yes, it's actually one of its main benefits: each measurement tool only fires if the visitor has given consent, thanks to Google's Consent Mode v2, working with Axeptio, Didomi or any other consent banner.

On a creation or redesign project, installation is included. On an existing site where scattered scripts need to be brought together: €500 to €1,200 depending on their number and the complexity of the firing rules.

PrestaShop, Shopify, WooCommerce, or any catalog exported from a custom-built site. Each platform has its own modules or catalog export methods, which I adapt to your needs.

The most common causes: missing or incorrect product barcode (GTIN), a gap between the price shown on your site and the one sent to Google, 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 platform with a dedicated module (PrestaShop, Shopify, WooCommerce): €400 to €900. With advanced rules and fine catalog segmentation for Google's Performance Max campaigns: €900 to €2,000 depending on catalog size.

Less and less. Between ad blockers and the privacy protections in Safari and iOS, the Pixel alone misses 20 to 40% of sales in its measurements. The Conversions API compensates for that loss: it sends the data directly from your site to Meta, without depending on the visitor's browser.

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 from €400/month excluding ad spend: measurement tools set up (Pixel, Conversions API), campaign management, 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 company (data hosted in Europe), often cheaper for high volumes of automatic emails (order confirmations, shipping notices and so on), with SMS sending built in. Mailchimp remains relevant for some very advanced automation scenarios.

Basic installation and configuration (automatic order emails + 2-3 automated scenarios): €600 to €1,500. Advanced contact targeting and complex multi-step scenarios: €1,500 to €4,000.

Yes, and I recommend it: your emails reach the inbox more reliably and look more polished. The Brevo module takes over from PrestaShop and sends these emails (order confirmation, shipping and so on) using your own templates.

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

Mailchimp excels at advanced automatic email scenarios and fine targeting based on buying behavior. Brevo is often more cost-effective for high volumes of automatic emails (orders, shipping) and also sends SMS. I advise you based on your volumes and needs.

Connection to your store and basic automatic scenarios: €600 to €1,500. Advanced targeting, recurring newsletters and systematic side-by-side testing of two email versions: €1,500 to €4,000.

Yes: I import your contacts from another tool or a spreadsheet file (CSV), with GDPR checks (consent really given, origin known). Contact groups are 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.
