Three questions advertisers keep asking

We answer each one with what we actually do.

  1. Question 01

    Why can't I see at a glance where the ad budget went and what it brought back?

    What Pango GY does

    We automate the whole path, from pulling results out of each platform to writing the report. Less time spent gathering numbers means faster decisions.

  2. Question 02

    Every platform reports a different conversion count. Which number do I trust?

    What Pango GY does

    We record conversions on the server, so the ones that browser and iOS policies were dropping get counted again. Then we read GA4 and platform data side by side.

  3. Question 03

    ROAS (return on ad spend) is holding steady. So why is revenue falling?

    What Pango GY does

    We compare what the platforms report with actual revenue and recalculate which ads really contributed. Then we rebuild the budget split around what we find.

Ad agency services

Strategy, campaign management, analytics and automation, handled by marketers and engineers working as one team.

  1. Data-led strategy

    We bring ad data scattered across platforms into one place, analyze it, and build a plan around your business goals. The growth roadmap rests on data, not on an account manager's hunch.

  2. Performance marketing

    We manage campaigns against outcomes you can count, such as revenue and leads. From Naver, Google, Meta and Kakao to TV commercials (TVC) and digital out-of-home (DOOH), we have run more than 4,300 campaigns to date.

  3. GA4 and data analytics consulting

    Starting from GA4 setup and analysis, we build the environment that collects and stores your ad performance data. Our engineers run the diagnosis themselves and find what needs a technical fix.

  4. Growth marketing

    Server-side tracking keeps counting conversions when tracking is blocked. Technical SEO fixes site structure so search engines pick it up. Search intent analysis reads what customers mean by what they type. We also use a custom ad engine, built in-house, to lift conversion rates.

  5. AI automation

    AI agents take on report writing, performance analysis and strategy proposals, which cuts the repetitive work. Anything that touches a campaign goes live only after a person has reviewed and approved it.

Naver, Kakao, Google, Meta: many platforms, one strategy

Advertising in Korea runs on local platforms as much as global ones. We manage Naver ads and KakaoTalk ads alongside Google, Meta, TikTok and YouTube, through to TV and out-of-home. We don't optimize each platform in isolation. We split the budget against a single business goal.

The numbers that changed after working with us

Four case results. Three of them are measured against the client's previous agency. We name the industry instead of the brand, and every figure is shown as it was reported in the case.

  1. Brand e-commerce

    Result

    Peak-season revenue, year over year
    +246%
    Peak-season ROAS (return on ad spend)
    550%+

    Challenge

    Repeat purchases were strong, but new customers weren't growing and branded search volume was falling year after year.

    What we did

    • Built a measurement setup on server-side tracking so no traffic data went missing
    • Automated platform data collection and reporting to shorten decision time
    • Compared platform-reported results with actual revenue to measure indirect contribution, then reallocated the budget

  2. Retail promotions

    Result

    ROAS vs. previous agency
    +120%

    Challenge

    With competition between retail platforms heating up, the job was to get more out of the ad budget at every recurring promotion.

    What we did

    • Redefined the core customer personas through data analysis and found efficient new channels
    • Designed the media mix, the budget split across channels, around those personas
    • Widened the audience using purchase-intent signals and broke the campaign structure into finer segments

  3. Lead generation (consultations and sign-ups)

    Result

    Leads collected vs. previous agency
    +330%

    Challenge

    Competitors were raising ad spend sharply, and the fight for leads, meaning consultation and sign-up requests, had overheated.

    What we did

    • Mapped the customer journey through to the request, based on traffic data
    • Improved organic search visibility through SEO consulting, so the brand showed up without ads
    • Improved CPA (ad cost per lead) with a custom bidding engine built in-house

  4. Automotive

    Result

    Leads (test-drive and consultation requests), year over year
    +200%
    CPA improvement vs. previous agency
    30%+

    Challenge

    As new models arrived, mostly EVs and SUVs, the brand needed a stronger online path: people research a car and book a test drive before they visit a dealership.

    What we did

    • Structured keywords by model and ran brand and non-brand keywords separately
    • Balanced traffic volume and efficiency with a keyword bid optimization algorithm

We don't build results that stop when the ads do

Get found in search. Sharpen targeting with data you collect yourself. Turn that data into content, and the content brings in more search traffic. We build this loop in five steps, so growth doesn't depend on ad spend alone.
