Google Ads
Search, Shopping, Performance Max and YouTube, structured around intent and measured against real outcomes.
How we workPerformance marketing agency
Paid attention, turned into customers.
We buy Google Ads, Meta Ads and specialist traffic for product, service and subscription brands, and for the performance networks that pay on results. Then we build the creative and landing pages that make that spend convert, inside guardrails you can see.
45+ years combined in media buying, media sales and the most competitive verticals online. MSG is new; the people behind it aren't.
How we buy
Built for partners who pay on performance.
Whether you pay per lead, per paying user or on revenue share, every dollar we spend runs inside rules you can see.
-
Guardrails on every dollar
Budgets are approved per campaign and per traffic source, each with a ROAS target and a floor. Below the floor, spend comes down fast; if it stays there, it pauses. Budgets only rise when the data has earned it, with your sign-off.
-
Your accounts, your data
Ad accounts carry your admin access from day one. Your funds stay separate and are spent only on your campaigns, and weekly reports reconcile to your tracking. Audit-ready at any time.
-
Bought for value, not volume
Leads and paying users are judged on what they're worth after they convert: cohort revenue and predicted ROAS from your tracking, not the cheapest front-end CPA.
-
Clean, compliant traffic
No bots, incentivized clicks, cloaking or review workarounds. Age-gating where required and platform policies followed, so accounts last and partners never inherit a problem.
What we run
Three ways we buy attention.
Google captures demand that already exists. Meta creates it. Custom media finds the people the big two miss or overcharge for. We manage all three against the same business numbers.
Meta Ads
Facebook and Instagram campaigns driven by structured creative testing and conversion signals you can trust.
How we workCustom media buying
Planning, sourcing, testing and managing the channels beyond Google and Meta, including specialist and age-gated networks.
How we workBuilt into every account, and organic
- Creative Concepts, hooks and short-form video built for testing, then improved by what the results show.
- Conversion Landing pages and funnels that match the ad, remove friction and make the offer clear.
- Measurement Tracking, attribution and reporting that connect ad spend to customers, revenue and margin.
- SEO & AEO Search and AI answer visibility built on expert content, clean technical foundations and tracking you can read.
Inside the accounts

Why it's built this way
- 1Brand is split out and capped. Branded clicks are cheap and convert well, so blending them in makes non-brand look better than it is.
- 2High intent is organized by search theme, not by product SKU. Each ad group points at a page that answers the query.
- 3Broad match only runs where conversion volume can steer it, with search terms reviewed weekly and negatives added.
- 4Shopping is split by margin tier, so the bid target reflects profit, not just revenue.
- 5Performance Max runs feed-only with brand excluded and is reported on its own, so it can't take credit for brand demand.
- 6Video prospecting is judged on blended lift and branded-search growth, not on platform-reported conversions alone.

Why it's built this way
- 1New concepts enter a dedicated test ad set with its own budget, so testing never resets the learning in the scaling campaigns.
- 2Winners graduate as concepts, not single ads, with fresh hooks queued before the current ones fatigue.
- 3A small lookalike cell runs as a control to check whether broad delivery is actually finding better customers.
- 4Retargeting is capped as a share of spend, so it can't inflate results by claiming people who would have bought anyway.

Why it's built this way
- 1The tracker, not the ad platforms, is the source of truth for revenue: conversions arrive by server-side postback and are matched to the click.
- 2Landers are compared on the same traffic. The quiz lander converts better, so it takes the budget and the advertorial gets a new angle.
- 3A new source runs as a capped test with a decision date. This one is under water, so it's fixed or cut, not scaled on hope.

Creative from live campaigns
Ads built to be tested.
Short-form video built for paid placements: client work in English and Spanish, product campaign creative across a dozen personas and accents, and animated product spots. Every piece is built around one hook worth testing.
How it works
How acquisition actually works.
Customers move forward from audience to conversion. What we learn moves back, into who we target, where we buy and what we make next. Explore each part of the system and how it connects.
01 · Who
Audience
The people worth reaching, and the moment they're in: searching with a need, or scrolling without one yet.
What we do here
We define the best customers from your own data (who buys, who stays, who refunds) rather than demographic guesses, and we separate demand that already exists from demand that has to be created.
Connects to
In practice: Cheap isn't the same as good
An audience that converts at a low cost but cancels in the first month is more expensive than one that costs more and stays. Audience decisions get made on customer quality, not on the first conversion.
02 · Intent
Captures demand that already exists. Someone types what they want and the right ad answers.
What we do here
We structure accounts by intent, keep query quality tight, run Search, Shopping, Performance Max and YouTube where each fits, and bid on conversion data that reflects real value.
Connects to
In practice: Two searches, two jobs
"Best running shoes for flat feet" and "running shoes sale" look alike, but one person is researching and the other is ready to buy. They belong in different ad groups, with different pages and different bids.
03 · Attention
Meta
Creates demand. People aren't looking for you yet; the right ad makes them want to.
What we do here
We run Facebook and Instagram around a structured creative testing program, broad audiences and clean Pixel and Conversions API signals, so delivery finds buyers rather than clickers.
Connects to
In practice: The creative picks the audience
Shown to the same broad audience, a confession-style hook and a product demo will reach different people. The delivery system finds whoever responds, so the creative effectively chooses who sees it.
04 · Reach
Custom media
Channels beyond the big two, such as TikTok, YouTube, CTV, podcasts, newsletters and publishers, when they reach the right people at a better price.
What we do here
We plan and source each channel case by case, give it a capped test with a decision date, and agree how it will be measured before any money is spent.
Connects to
In practice: Measuring what a pixel can't see
A newsletter sponsorship can't be tracked click by click. A dedicated landing page, an offer code and a post-purchase "where did you hear about us" question can still show whether it worked.
05 · Message
Creative
The ad itself. It decides who stops scrolling, who understands the offer and who clicks.
What we do here
We write and produce concepts, hooks and short-form video built to be tested, cut for every placement, and improved using what each round of results shows.
Connects to
In practice: Where the difference sits
Two ads with the same body and different first three seconds can perform very differently. That's why we produce several hooks per concept, and why concepts are tested before polish.
06 · Promise
Landing page
Where the ad's promise is kept or broken, usually within the first screen on a phone.
What we do here
We design and build pages that continue the ad's message, put the offer and price up front, remove friction, and load fast on mobile connections.
Connects to
In practice: Message match
If an ad promises "first month free" and the page opens on a generic homepage banner, many visitors leave before scrolling. A page that opens on that exact offer keeps the thread unbroken.
07 · Outcome
Conversion
The action that matters, whether a purchase, a subscription or a qualified lead, and what happens after it.
What we do here
We define conversions that reflect business value, reduce drop-off in forms and checkout, and make terms such as billing and renewal clear, so customers stay converted.
In practice: A trial isn't a customer
For subscription offers, optimizing toward trial starts can attract people who never pay. Where volume allows, sending paid-conversion or renewal signals back teaches the platforms to find people who stay.
08 · Learning
Measurement
Turns outcomes into decisions: what to fund, what to cut, which audiences to pursue and what to make next.
What we do here
We combine clean platform tracking with first-party results and controlled tests, report acquisition cost and customer quality alongside platform numbers, and feed better signals back into every channel.
Connects to
In practice: When the platforms add up to more than 100%
Google and Meta can both claim the same sale. Comparing their reports with blended, first-party results shows how much of the combined total is overlap, and where budget is actually earning its keep.
An explanatory model of how we manage acquisition, not a software product or live data.
What does MEGA Stone Growth do?
MEGA Stone Growth (MSG) is a performance marketing agency. We plan, buy and manage paid media, mainly Google Ads, Meta Ads (Facebook and Instagram) and other channels through custom media buying, and we produce the performance creative, landing pages and measurement that make that media profitable.
Do you buy media for affiliate networks and performance partners?
Yes. We buy for networks and advertisers who pay per lead, per paying user or on revenue share. Budgets are approved per campaign and traffic source, every source runs against a ROAS target and floor, the ad accounts carry your admin access, and weekly reporting reconciles to your tracking.
Do you only run Google and Meta?
No. Google and Meta are the core of most plans, and we also buy across other channels such as TikTok, YouTube, Pinterest, Reddit, programmatic, connected TV, podcasts, newsletters and direct publisher placements, plus specialist native, push, pop and age-gated networks for offers that need them, when they suit the audience and can be measured.
Can you work in categories where ads are hard to get approved?
Yes. Much of our experience comes from verticals where platform review is strict and margins are thin. We build offers, creative and landing pages that pass review and keep ad and payment accounts healthy. We don't use cloaking or any tactic designed to get around policy.
Who is behind MSG?
A team with more than 45 years of combined experience in digital media: building and running large-scale media buying teams, selling media from the publisher side, and leading growth in some of the most competitive verticals online. MSG is a new agency; the people running your account are not new to this.
Is there a minimum budget?
We don't publish a fixed minimum. What matters is whether your budget can produce enough conversions for the platforms, and for us, to learn from. If it can't yet, we'll tell you in the first conversation.
