Multilingual SEM: Google Ads, Bing Ads and Meta Ads piloted per market
Native keyword research per language. Campaign architecture aligned with multilingual SEO structure. Honest reporting on CPL and ROAS per market, not vanity metrics.
4+ platforms
Google Ads, Bing Ads (especially relevant US B2B), Meta Ads, LinkedIn Ads for B2B targeting
CPL / ROAS
cost per qualified lead and return on ad spend per market, not vanity metrics
Native ads
ad copy written natively per market, not translated from a master campaign
SEM + SEO
paid and organic strategies aligned, sharing keyword research and landing pages
Three patterns that drain ad budgets
Recurring issues I see on multi-market paid campaigns:
One master campaign translated to every market
A US Google Ads campaign translated to French, Spanish and German keeps the original keyword set, ad copy structure and bidding strategy. Result: low Quality Score per market because the keywords are not how locals search, ad copy reads stilted, landing pages feel imported. CPC climbs, conversion drops. Native ad campaigns per market beat translated campaigns in every meaningful test I have run.
Bidding on keywords no one searches
Keywords picked from Google Keyword Planner without verifying real intent or local search behaviour. The result: high impressions, low CTR, irrelevant clicks, wasted spend. Real keyword research means checking actual SERPs in the target market, validating with native speakers, and starting with tighter intent buckets rather than broad match.
No conversion tracking per market
Generic conversion tracking that mixes all markets together. You cannot tell which language is profitable, which is bleeding budget, which is mid. Decision-making becomes guesswork. Each market needs its own conversion tracking, attribution and KPI report. Without that, optimisation is theatre.
Multilingual SEM is sequencing and discipline, not just translating ad copy. Campaigns built per market with native research, distinct ad accounts where it makes sense, dedicated tracking. Aligned with the multilingual SEO structure to share keyword research and landing pages.
What I include in a multilingual SEM engagement
Native keyword research per market
Real research in each target language. Intent classification, exclusion of low-quality terms, validation by native speakers before bidding.
Campaign architecture per market
Distinct campaigns or ad groups per market, separate budgets, distinct bidding strategies. No master campaign translated.
Native ad copy per market
Headlines, descriptions and assets in each language by natives. Direct in FR / EN / ES / NL. BeTranslated network for DE, IT, PT and others.
Landing pages aligned with ads
Dedicated landing pages or use of existing SEO pages per market. Quality Score on Google Ads improves with proper landing alignment. Conversion tracking installed per page.
Conversion tracking and reporting
GA4, GTM, server-side tracking where needed. Conversion KPI per market: CPL, ROAS, qualified pipeline. CRM sync to qualify leads beyond the click.
Cross-platform allocation
Google Ads as default. Bing Ads where US B2B audience justifies (Microsoft ecosystem). Meta Ads for B2C reach. LinkedIn for B2B targeting in specific verticals.
My process in 5 steps, named deliverables
Audit, native research, build, launch, optimise. No spending before scoping is validated.
1. Account audit (week 1)
Deliverable: diagnostic of current accounts (Google Ads, Bing Ads, Meta Ads): structure, spend allocation, performance per market, wasted budget on irrelevant keywords or audiences, conversion tracking gaps.
2. Native keyword research (week 2)
Deliverable: distinct keyword spreadsheet per market. Volumes, CPC estimates, intent classification, negative keyword lists per language. Validated by native speakers before any bidding decision.
3. SEM strategy doc (week 3)
Deliverable: campaign architecture per market (Search, Display, Performance Max as relevant), budget split, bidding strategy, ad copy briefs, landing page plan, conversion tracking spec, monthly KPI targets.
4. Build and launch (week 4)
Deliverable: campaigns built per market with native ad copy, conversion tracking validated end to end (GA4 + GTM + CRM where applicable), landing pages aligned, dry-run audit before activation. Soft launch with conservative budget for the first 2 weeks.
5. Optimisation and reporting
Deliverable: weekly checkpoints during the first month, monthly reporting thereafter. KPIs: CPL per market, ROAS per market, qualified pipeline per market, share of voice on key terms. Decision points to scale, hold or kill per market based on hard data.
Multilingual SEM case studies
Three engagements where paid campaigns spanned multiple languages or markets.
TX International Freight (US)
Context: Houston-based freight forwarder running Google Ads in English (US) and Spanish (LatAm). Bing Ads also relevant given the US B2B audience using Microsoft ecosystem.
Build: separate campaigns per language and per transport mode (ocean, air, customs), native keyword research in EN and ES with distinct intent buckets, dedicated landing pages, conversion tracking from form submission through to quote-issued status in the CRM.
Outcome: CPL on the Spanish campaign came in 30-40% lower than the English campaign once native LatAm keyword research replaced the initial translated set. Combined with SEO, daily quote pipeline doubled over 18 months.
Law firm in Valencia (ES)
Context: Valencia-based law firm specialised in business law and franchising, running Google Ads in Spanish (primary), French and English (secondary).
Build: tightly-targeted search campaigns on commercial-intent legal queries per language, separate accounts per language to keep Quality Score clean, landing pages on practice-area pages of the main site, lead form with sector qualification.
Outcome: recurring qualified leads from prospects searching for Valencia business law counsel in three languages, CPL maintained at a level compatible with the firm’s average revenue per case.
BeTranslated network
Context: translation agency running Google Ads across multiple European country domains. Each market has its own primary language, commercial conventions and competition landscape.
Build: separate Google Ads accounts per country (clean Quality Score per ccTLD), native keyword research per language by the in-house translator team, distinct ad copy per market, landing pages on the local domain.
Outcome: steady cost per qualified lead per market, monthly reporting that identifies which countries are profitable vs which need adjustment, no cross-contamination across markets.

Why this team for multilingual SEM
Michael Bastin: 25 years in SEO and SEM. Direct fluent execution on Google Ads in French, English, Spanish and Dutch. Native team coverage for German, Italian, Portuguese and other languages.
SEM aligned with SEO from day one: same keyword research universe, same landing pages where possible, same multilingual architecture. The paid and organic strategies inform each other instead of competing for budget.
Transparent media buying: budget paid directly to Google, Microsoft and Meta. No agency markup on spend. Management fee is the only compensation line, which keeps incentives aligned with your results, not with your gross ad spend.
When does SEM make sense vs SEO?
Both, sequenced thoughtfully.
SEM first: when you need pipeline now, when SEO will take 6-12 months to mature, when you have budget to test market demand quickly, or when your offer is new and requires immediate signal.
SEO first: when CPC in your sector is prohibitive, when your buyers research extensively before contacting (long sales cycles), or when budget is too tight to sustain paid acquisition at scale.
Both in parallel (most common): SEM captures the bottom-of-funnel commercial intent traffic while SEO is building. As SEO matures, SEM budget can be redirected to less competitive expansion markets or non-branded queries.
Reasoned recommendation given at scoping based on your situation.
Frequently asked questions on multilingual SEM
Should I run separate Google Ads accounts per market?
Often yes for markets with significant budget or strict Quality Score sensitivity. Separate accounts keep performance data clean per country and let you set distinct payment, billing and conversion currency. For markets with low budget or test-only scope, ad groups within one account work fine. The decision is part of the scoping.
How do you handle currency and budget allocation across markets?
Each market gets its own monthly budget cap in local currency (or EUR/USD with FX conversion). Spend is reported per market separately. Reallocation decisions happen monthly based on CPL and ROAS per market. No “global budget” pool that hides which markets are draining.
Are Bing Ads still relevant in 2026?
For US B2B yes. Microsoft’s Bing/Edge ecosystem has a high penetration in US corporate environments (Office 365 users default to Edge/Bing). CPC is generally lower than Google Ads on equivalent queries with smaller volume. For Europe, Bing Ads matters less but can still complement Google Ads on specific verticals. Decision made per market in scoping.
Do you charge a percentage of ad spend?
No. Management fee is a fixed monthly amount based on scope (number of markets, platforms, campaigns, complexity). Media budget is paid directly to Google, Microsoft, Meta — no markup, no margin on spend. Incentive aligned with your performance, not with how much you spend on ads.
How fast do you scale ad spend?
Conservative initial period: 2-4 weeks at controlled budget while tracking validates and Quality Score builds. Then scale aggressively on what works, kill what does not. Most multi-market campaigns reach steady-state monthly spend by month 3.
Can you work with my existing Google Ads or Meta account?
Yes. I prefer working in your existing accounts when they have history (Quality Score, audience signals, conversion data). Audit first, restructure if needed, then optimise. Starting fresh is recommended only when the existing account has accumulated bad signals (low Quality Score across the board, conversion tracking broken for months).
How much does a multilingual SEM engagement cost?
Quoted. Management fee depends on number of markets, platforms, complexity. Ad spend depends on competitive landscape and growth targets. Free first call: 30 minutes to understand your context and give honest ranges for both. No generic proposal sent without a conversation.
Ready to scale paid acquisition across markets?
I start by auditing your current paid accounts and identifying wasted spend per market. Quantified diagnosis, actionable recommendations. Free first call, no commitment.
