Market context

Google dominates search in France (~90% market share).
Bing ~5% in France but Microsoft search share is higher in some regions (US ~20–30%).
Russia and China have strong local search engines — check local market shares when selling internationally.

Search campaigns — key concepts

Keyword-driven auctions: you set a max CPC (bid); Google uses the auction plus Quality Score to rank ads.
Quality Score (0–10) factors: ad relevance, expected CTR, landing page relevance. Higher scores reduce effective CPC and can help outrank higher bids.
Match types:
- Exact ([brackets])
- Phrase (“quotes”)
- Broad (default)
- Broad match modifier (+) has been deprecated — use negative keywords to exclude unwanted queries.
Account hierarchy: Customer account → Campaigns (budget, type) → Ad groups (keywords, ads, final URL).
Ad format limits: up to 3 headlines (30 characters each), up to 4 descriptions (90 characters each), display path, plus ad extensions.
Bidding strategies: manual CPC or smart bidding (e.g., maximize clicks/conversions). Smart bidding still operates via bids; conversion tracking is required for many automated strategies.
Campaign settings to configure: geography, language, ad schedule, devices, network partners (recommendation: uncheck search partners & display network for tighter control).
Recommended starting daily budget per campaign: €10–€20 (campaigns can technically run from €1/day but this is usually impractical for meaningful data).

Google Shopping (Product Listing Ads)

Essential for e-commerce: visual ads showing product image, title, price, brand, reviews.
Requires a product feed and a Merchant Center account. Feed options:
- Native Shopify / WordPress integrations (preferred)
- Google Sheets (small catalogs)
- API / XML feed (large catalogs — recommended)
Shopping does not accept keyword targeting; Google generates queries from feed metadata (titles, descriptions). Feed completeness and quality are critical.
Two main Shopping approaches:
- Standard Shopping — more manual control
- Performance Max — highly automated across channels, less control (Google favors/promotes Performance Max)
Products can appear in both Shopping results and Search (dual exposure).

Keyword research

Use Google Keyword Planner, Google Search Console, your site sitemap and client input to identify relevant keywords and get CPC estimates.
Match search intent — prioritize buying-intent keywords (e.g., “buy iPhone” vs “iPhone”).

Conversion tracking

Define conversions (purchase, form fill, call) and assign values. Use dynamic values for e-commerce or default values for leads.
Conversion window default is 30 days (conversion is attributed to day of click). Extend the window for long sales cycles (B2B).
Attribution model: data-driven attribution is recommended for most cases.
Conversion tracking is essential for optimization and required for smart bidding; without it you are “flying blind.”

Tagging and implementation

Use Google Tag Manager (GTM) to deploy Google tags and conversion tags without repeatedly editing site code.
Install GTM snippets in head and body; use GTM Preview mode and Tag Assistant for debugging.
Create a Google Ads conversion tag in GTM and trigger it on the purchase/thank-you page (or fire on a conversion event).

Reporting & optimization

Use the Search Terms report to see actual queries (including those triggered by Shopping) and add negative keywords where needed.
Monitor impressions, CTR, CPC, conversions and ROI; reallocate budget from low-performing to high-performing campaigns.
Structure accounts semantically (by product categories / sitemap) to improve relevance and Quality Score.
Let Google optimize ad rotation (recommended by presenter), but maintain manual controls where transparency or granularity is needed.

Pros

High-intent traffic — users on Google often have purchase intent, improving conversion potential vs social platforms.
Precise attribution — tie conversions to keywords, time, device, and region.
Immediate traffic once campaigns and tags are active.
Google rewards relevance (Quality Score), not only the highest bid.
Google Shopping is especially effective for e-commerce (visual format, high conversion).
Supportive tools (Keyword Planner, Merchant Center, GTM) facilitate experimentation and scaling.

Cons / risks

Technical complexity: feed setup, tagging, GTM and conversion configuration may require developer help or platform integrations.
Risk of wasted spend if misconfigured (poor structure, wrong match types, no conversion tracking, no bid guards).
Performance Max is opaque and can overspend or reduce advertiser control.
Google product recommendations can be biased toward Google’s revenue and not always optimal for advertiser ROI.
Shopping performance depends entirely on feed quality — poor feeds yield poor results.
Broad match may trigger irrelevant traffic if not tightly managed with negatives.

Practical tips & recommended workflow

Plan account structure on paper first (campaigns → ad groups → keywords → ads → landing pages).
Start with phrase and exact match for control; use broad match sparingly and monitor carefully.
Always add negative keywords to exclude irrelevant queries.
Start Shopping with Standard Shopping (control) before experimenting with Performance Max.
Implement conversion tracking before optimizing bids or enabling smart bidding.
Use GTM for tag deployment; test with preview mode and Tag Assistant before publishing.
Set bid guardrails (max CPC limits) during the learning phase to avoid runaway spend.
Recommended daily budget per campaign: €10–€20 for meaningful data.
Uncheck search partners and display network by default — add them only if you test and verify performance.
Use Keyword Planner and Search Console to seed keyword lists, then refine with live campaign data.

Comparisons with other platforms

Bing Ads: worthwhile alternative where Microsoft has meaningful share (notably the US). Google Ads campaigns can be imported into Bing.
Meta / LinkedIn / TikTok: generally lower purchase intent — better for awareness than direct intent-based conversions.
Performance Max vs Standard Shopping: Performance Max offers broader automation and reach but less control; Standard Shopping gives granular control.

Presenter & user experience notes

Single presenter leads a hands-on walkthrough of campaign creation, ad and keyword entry, Shopping setup, and GTM tagging.
Presenter points out occasional platform glitches and demonstrates previewing and troubleshooting.
Emphasis on testing, iterating, and using performance data rather than blindly following Google’s automated recommendations.

Numerical examples & figures cited

Market share examples: Google ~90% in France; Bing ~5% in France; Microsoft search ~20–30% in the US (approx.).
Recommended budget examples: start at €10–€20/day per campaign.
Illustrative CPC example mentioned: iPhone bids of €0.50–€0.70.

Concise verdict / recommendation

Google Ads is the primary platform for demand-driven advertising and is essential for e-commerce (Google Shopping). Use Search for intent-driven traffic and Shopping for product visibility. However, plan carefully: set up account structure, conversion tracking and tag management before launching, apply bid guardrails, start with Standard Shopping and controlled bidding, and only later consider automated strategies like Performance Max once you understand the behavior and risks.

Key operational reminder: set up conversion tracking and tag management (GTM) before relying on automated bidding — otherwise optimization will be ineffective.
