Digital Advertising Service

Digital Advertising

We run Google, Facebook, TikTok and Zalo campaigns against the only two numbers that decide anything — what a customer costs you, and what a customer is worth. Ad accounts stay in your name, spend is visible to you every day, and each report says what we changed and why.

What we run

Advertising across the channels your customers actually use

Search for the people already looking, social for the people who have not heard of you yet, and remarketing for the majority who left without buying. Which mix depends on what you sell, not on which platform is fashionable.

Google Search Ads

The highest-intent traffic there is: someone typing exactly what you sell. Keyword research, tight ad groups, negative keyword discipline and bidding managed against your target cost per customer.

Search · Keywords · Negatives · Smart bidding

Google Display & YouTube

Reach and remarketing across the web and YouTube — including the visitors who came from search, left, and need to see you a few more times before deciding.

Display · YouTube · Remarketing lists

Google Shopping & Performance Max

For retail: a clean product feed, prices and stock kept in sync, and campaigns that put the actual item with its photo in front of a shopper mid-search.

Product feed · Shopping · Performance Max

Facebook & Instagram Ads

Audience building, lead forms, catalogue and dynamic product ads, and retargeting warm audiences — with creative tested properly instead of one image left running for a year.

Meta · Lead forms · Catalogue ads · Retargeting

TikTok Ads

Short-form video where the creative carries almost all of the result. We produce and rotate hooks rather than boosting one post and hoping it holds attention.

Short video · Hook testing · Spark ads

Zalo Ads & Messaging

The channel most Vietnamese customers actually answer. Zalo OA setup, message ads and follow-up flows that land where enquiries do not go cold overnight.

Landing Pages & Conversion Optimisation

The ad only buys the click; the page decides whether it was worth it. We build and test the page too, which is usually the cheapest place to improve a campaign.

Landing pages · A/B testing · CRO

Tracking, Attribution & Reporting

Conversions measured properly before a single dong is spent: GA4, Tag Manager, pixels, server-side events and call tracking, feeding a dashboard you can open any time.

Why advertise

Why paid advertising is the fastest channel you can buy

SEO and content compound over months. Advertising starts tomorrow morning, and every dong of it is attributable — which makes it the only channel where you can prove what a customer cost you before you decide whether to spend more.

  • Demand that already existsSearch puts you in front of someone who is typing your product into Google right now. No persuasion needed — only being there and being credible.
  • Reach people who have never heard of youSocial and video create demand rather than harvest it, which is how you grow beyond the size of your current search volume.
  • Bring back the ones who leftThe large majority of first-time visitors leave without buying. Remarketing is almost always the cheapest conversion in the account.
  • Measurable down to the individual adUnlike a billboard, you can see which keyword, audience and creative produced each enquiry — and stop paying for the ones that produce none.
  • A tap you can turn the same dayQuiet month, spend more. Warehouse out of stock, pause it by lunchtime. No other channel responds that quickly.

And when ads are the wrong spend

We will say so during the audit, before you fund a campaign. Advertising is a poor fit when:

  • Your landing page does not convert. Ads will only buy you an expensive proof of that, faster.
  • The margin cannot carry a customer at the going rate for your keywords — some markets are simply bid too high.
  • Nobody answers enquiries within the hour. Paid leads go cold faster than any other kind.
  • You have no tracking. Spending without measurement is not marketing, it is donation.

In those cases we fix the page and the tracking first, or recommend you put the budget into SEO and content instead — a slower channel, but a cheaper one that keeps working after you stop paying.

Platforms & tools

Where we run and how we measure

The platform matters less than the measurement behind it. Without conversion tracking wired in properly, every optimisation decision after launch is guesswork dressed up as strategy.

What we optimise for

Campaigns by objective

An account should be built around the outcome you are buying. These six cover almost everything our clients ask for — and each one is measured differently.

Lead generation

Enquiries for services, consultations and quotes, priced on cost per qualified lead rather than raw form fills.

→ search + lead forms
→ CRM-verified quality
→ cost per qualified lead

E-commerce sales

Product feed, shopping and dynamic remarketing, measured on return on ad spend at the product-category level, not the account average.

→ shopping & catalogue ads
→ dynamic remarketing
→ ROAS by category

App installs

Installs that actually open the app twice. Campaigns tuned to in-app events, not to whichever network reports the cheapest install.

→ store listing ads
→ in-app event tracking
→ cost per active user

Local store footfall

Radius targeting, map listings and calls, for businesses whose customers have to physically arrive at an address.

→ radius targeting
→ Google Business Profile
→ call & direction tracking

Brand awareness & launch

Getting a new product or company known in a defined market, with reach and frequency capped so you are not paying to annoy the same people.

→ video & display reach
→ frequency capping
→ brand search lift

Remarketing & retention

Bringing back visitors, abandoned carts and past customers — usually the cheapest conversions in any account, and the first thing we set up.

→ abandoned cart
→ past-customer audiences
→ cross-sell campaigns
How we deliver

Six stages, and spending starts at stage four

Most wasted ad budget is spent in the first month, on campaigns nobody could measure. We set up the measurement first, then buy traffic against it.

Stage 01

Audit & goals

Your existing accounts, what a customer is worth to you, and the cost per customer that would make the channel profitable. Without that number there is nothing to optimise towards.

1 week→ audit + target CPA
Stage 02

Tracking setup

GA4, Tag Manager, platform pixels, server-side conversions and call tracking, tested end to end with real submissions before any campaign goes live.

1 week→ verified tracking
Stage 03

Structure & creative

Account structure, keywords and audiences, negative lists, then ad copy and creative built in enough variants to learn something from the first month.

1–2 weeks→ campaigns ready
Stage 04

Launch & learning

Controlled budget while the platforms gather data. We resist judging a campaign before it has enough conversions to say anything meaningful.

2–4 weeks→ first live data
Stage 05

Optimisation

Bids, budgets, negative keywords, audience exclusions, landing page tests and creative rotation — weekly, with every change logged so you can see the reasoning.

ongoing→ weekly change log
Stage 06

Reporting & scaling

A monthly review in plain language: what it cost, what it returned, what we changed and where the next increase in budget should go — or whether it should.

Why CTG

We can fix the page the ad lands on

Most agencies can only change the campaign. CTG builds the website, the landing page and the tracking too — so when the problem is the page rather than the traffic, we can actually do something about it.

01

The accounts are yours

Google Ads, Meta Business and analytics properties are created in your company's name with us added as a partner. If you leave, you keep the history — which is the part that took months to build.

02

Tracking before spending

No campaign launches until a real conversion has been recorded end to end. Every account we inherit that was losing money was also, without exception, measuring something wrong.

03

Reported on customers, not impressions

Reach and clicks are inputs. The report leads with what a customer cost and what they were worth, then explains the changes we made and what we expect from them.

04

We will tell you to spend less

When a channel stops being profitable at higher budget, the right advice is to cap it. We would rather keep a client for years than grow an invoice for one quarter.

Questions

What clients ask us first

How much should we spend to start?

Enough for the platform to learn, which depends on your cost per click and how many conversions you need before the data means anything — roughly thirty conversions a month is where optimisation starts working properly. Working backwards from that gives a realistic starting budget for your market. If that number is beyond what you can commit for three months, we will say so rather than spread a small budget thinly across four channels and produce nothing on any of them.

Google or Facebook — which should we start with?

If people already search for what you sell, start with Google: you are harvesting demand that exists, and the intent is higher. If your product is discovered rather than searched for — a new concept, an impulse purchase, something visual — start with Meta or TikTok, where the creative creates the demand. Most accounts end up running both, with remarketing bridging them. We recommend one after the audit rather than defaulting to whichever we prefer to manage.

Who owns the ad accounts and the data?

You do. Accounts are created under your company's Google and Meta business managers, with CTG added as an agency partner. All conversion history, audience lists and creative assets stay in your accounts. If you ever move to another agency, you hand over access rather than starting from zero — the accumulated learning is the most valuable thing in an ad account and it should never belong to the agency.

How long before we see results?

First data within days, but do not judge on it. Search campaigns usually take two to four weeks to stabilise; social and video need long enough to test several creative angles. Give it a full quarter before deciding whether the channel works for you, and expect the first month to be about learning what to switch off. Anyone promising profitability in week one is describing luck, not a method.

How do you charge — a percentage of our spend, or a fixed fee?

Both models exist and we will agree one in the proposal. Worth knowing the difference: a percentage of spend is simple but means your agency earns more when you spend more, which is a conflict on the day the honest advice is to spend less. A fixed monthly fee removes that. Ask us for whichever you prefer, and ask any agency you talk to the same question.

Can you take over our existing account instead of starting again?

Usually yes, and it is often better — the conversion history in an established account is worth keeping. We start with an audit: what is being measured, what is being wasted, and which campaigns are worth restructuring rather than rebuilding. Occasionally an account is tangled enough that a clean build is faster, and if so we will explain exactly why before touching anything.
