NYC-first awareness and reach

The best New York agencies know how to use the city as a media advantage, not just a headquarters. We plan awareness with channels that suit NYC density: Connected TV, high impact video, and Digital Out Of Home where it makes sense, paired with brand-safe verification. Then we connect that reach to measurable outcomes using geo experiments, cohort movement, and clean tracking. You get creative that fits each placement and a measurement plan that proves whether awareness spend creates incremental demand.

CTV and DOOH planning

Use CTV and DOOH selectively for high impact reach, with creative built for the placement and guardrails for frequency and brand safety.

Hyper-local NYC targeting

Run borough-level testing using geo fencing and dynamic creative so Manhattan and Brooklyn audiences see messaging that matches context and intent.

Proof with lift testing

Validate impact using geo holdouts and cohort shifts, then decide what to scale based on incremental lift, not view-through attribution.

Plan awareness

Complete team, no hiring drag

Most buyers looking for the best New York agencies are really trying to avoid slow hiring and fragmented execution. Growthcurve gives you a complete marketing department in one package, with specialists across paid, creative, analytics, SEO, and CRO. We integrate with your internal staff and move fast because the operating cadence is already set. You get the benefits of a large team without the overhead, management load, and long lead times of building in-house.
  • Complete department in one
  • Integrates as internal staff
  • Faster than hiring

Mid funnel personalisation at scale

Most agencies lose efficiency in the middle of the funnel, where audiences need tailored proof and repetition. We unify first party data from your CDP and analytics to build audience segments based on predicted value, then deploy retargeting sequences across Meta, TikTok, Snapchat, and YouTube. Creative is sequenced by stage, not sprayed at everyone. The outcome is higher quality consideration and faster movement from engaged users to pipeline or purchase, with clearer insight into what actually changes behaviour.

First party audience segmentation

Segment by behaviour and value signals, not broad demographics, so creative and bids focus on audiences most likely to become high LTV customers.

Sequenced retargeting creative

Build retargeting that moves users through proof, objections, and offers, with frequency controls and exclusions to protect efficiency.

AI-assisted personalisation workflows

Use AI tooling to generate and test more variants quickly, then promote winners into broader spend based on clear, documented learnings.

Improve nurture

Bottom funnel efficiency and tracking

At the bottom of the funnel, the best New York agencies win by combining platform automation with better inputs. We tighten conversion signals using first party event design and server-side API tracking where appropriate, then run Google Performance Max and Meta Advantage+ style approaches with stronger data and clearer creative direction. We also reduce leakage with CRO sprints and lifecycle automation. The goal is lower CAC and more predictable scaling without relying on fragile last click attribution.

Performance Max and Advantage+

Use automation responsibly by feeding it clean conversions and strong creative, then monitor query, placement, and audience patterns to avoid wasted spend.

Server-side measurement foundations

Improve resilience with server-side tracking and clear event definitions, so optimisation remains accurate despite privacy changes and signal loss.

CRO and retention compounding

Run CRO prioritised by revenue impact, then add lifecycle flows that increase repeat purchase and payback, making acquisition more scalable.

Lower CAC

Flexible, month to month engagement

NYC agency retainers often lock you into long commitments while priorities change every quarter. We work on a monthly rolling basis so you can keep momentum without being trapped in a scope that no longer fits. That flexibility also means we can scale resources up or down: more creative when you are testing new offers, more analytics when attribution is unclear, more CRO when traffic is there but conversion is not. You stay in control while we execute.
  • Monthly rolling, no lock-in
  • Scale specialists on demand
  • Avoid unreliable freelancers

SEO that compounds, not a checklist

Organic growth is a mix of technical hygiene, content that earns clicks, and authority building that is genuinely deserved. We treat SEO as a product, with a backlog and a cadence, rather than a one-off project. Technical work covers crawlability, site architecture, Core Web Vitals, schema markup and index management. On-page work is driven by search intent and the real questions buyers ask at each stage. Off-page focuses on link earning through useful assets, partnerships and digital PR rather than spam. For example, for a B2B brand we might build a set of comparison pages for demand capture, a small research piece to earn links, and a library of problem-led articles that support sales calls. The outcome is more qualified traffic, better brand credibility, and lower dependency on paid media over time.

Performance without the agency tax

Some agencies get paid more when you spend more, which quietly misaligns incentives. We do not charge commission on your ad spend, and we focus on evidence-led optimisation that protects unit economics. Our proprietary AI marketing tools and real time dashboards reduce manual busywork and help surface what to fix next, faster. The result is more tests shipped, clearer accountability, and better decisions about where to scale and where to stop.
  • No commission on ad spend
  • Evidence-led optimisation cadence
  • AI tools speed execution
What do best New York agencies do differently?
They connect creative excellence to measurable performance. That means a clear full funnel plan, rapid iteration, and measurement that stands up when attribution is noisy. The best teams also show their work: hypotheses, test plans, and learnings that compound. If an agency cannot explain how it validates incremental lift or how it decides what to test next, you will end up paying for activity instead of outcomes.
Should we invest in CTV and DOOH in NYC?
CTV and DOOH can be effective in NYC because reach is concentrated and creative formats can be high impact. The decision should depend on your category, margins, and whether you can measure downstream impact. We recommend treating awareness as a testable investment: define geo markets, set frequency controls, and validate lift with holdouts or geo experiments. If you cannot measure impact, prioritise demand capture first.
How do you run hyper-local targeting across NYC boroughs?
We plan borough and neighbourhood tests with geo fencing and tailored creative, then compare outcomes using consistent measurement windows. The point is not just higher engagement, but better conversion efficiency and pipeline quality. We also control overlap so tests stay clean, and we use creative sequencing so audiences see the right proof at the right stage. Hyper-local only helps when it ties back to a measurable funnel outcome.
How do you measure performance after privacy changes?
We strengthen first party signals, tighten event definitions, and implement server-side tracking where appropriate. That improves the quality of conversion feedback loops for platforms like Google and Meta. Then we validate results using incrementality methods such as geo holdouts. This reduces dependence on last click and platform-reported attribution, which can over-credit retargeting or undercount cross-device journeys in a low-signal world.
Do you manage Google Performance Max and Meta Advantage+?
Yes, when the foundations are right. Automation performs best when you supply clean conversions, accurate value signals, and strong creative. Without that, these systems can scale spend into low quality traffic. We start with measurement and feed quality, then run structured creative testing and query and placement monitoring. The goal is scalable efficiency, not blind automation that looks good in platform reporting but fails in the business.
What is your approach to creative testing velocity?
We treat creative as a performance lever and run a repeatable testing system. Each week we test a small set of variables such as hook, offer framing, proof type, and format, then document learnings. Unlimited creative production is included, so you are not blocked by a separate studio. We prioritise speed with discipline: fast iteration, clear hypotheses, and winner promotion based on real funnel performance, not subjective preferences.
How do you reduce fraud risk and improve media quality?
We use brand safety and verification controls where relevant, plus placement and frequency management to reduce waste. We also monitor anomalies in performance and traffic quality, then tighten targeting and exclusions when patterns suggest low quality inventory. Quality is not just fraud checks. It includes ensuring creative matches the placement, landing pages load quickly, and conversion signals are reliable, so platforms optimise towards real customers.
Are you a long contract agency or month to month?
We operate on a monthly rolling basis. That keeps incentives aligned and gives you flexibility as priorities change. It also allows you to scale specialist support up or down without renegotiating a long contract. If your procurement process requires fixed scope, we can define milestones and success criteria, but we still prefer a flexible model so budgets and resourcing follow evidence rather than locked deliverables.
What should we ask for in an agency RFP?
Ask for a clear operating cadence, sample reporting, and examples of how they decide priorities. You should also request evidence of testing discipline: how they structure experiments, how they measure lift, and how they document learnings. Commercially, ask whether they charge commission on ad spend, who owns creative and accounts, and what happens if performance stalls. A good agency welcomes these questions and answers directly.

Lifecycle marketing that increases LTV

If you only optimise acquisition, you end up paying more for the same customers. We build lifecycle systems that raise retention and expansion, using email, SMS where relevant, and CRM workflows that feel personal without being creepy. We set up segmentation based on behaviour and value, then design flows for onboarding, activation, replenishment, win-back and referral. In practice that can include RFM modelling for ecommerce, lead scoring for B2B, or product usage triggers for SaaS. We also help you capture first-party and zero-party data with preference centres and progressive profiling, so targeting stays resilient as privacy changes. When we ran a lifecycle audit for one team, we found revenue sitting in overlooked moments, like post-purchase education and renewal risk signals. The outcome is a healthier blended CAC and a marketing engine that keeps paying you back.

Measurement you can trust and use

Attribution arguments waste time and block good decisions. We set measurement up so it is good enough to guide spend, creative and roadmap choices, and we are honest about what is knowable. Tracking work can include GA4 hygiene, conversion event design, server-side tracking where appropriate, and consistent UTMs. Reporting lives in a real-time dashboard, with views that match how you run the business, such as channel performance, funnel conversion, cohort retention and creative learnings. We also use incrementality thinking where it matters, like geo holdouts or controlled tests for bigger budget shifts. For example, if brand search rises after a video push, we look at the whole picture rather than declaring victory based on last click. The outcome is faster iteration and fewer surprises in board meetings.

Operating rhythm, SLAs and ways of working

Good marketing is mostly good operations. We set a working rhythm that keeps delivery moving and prevents strategy decks from becoming a comfort blanket. You get a named lead, specialist channel owners, and access to top-tier US and UK talent, scaled up or down based on your needs. We agree response times, approval flows and who owns what across creative, landing pages, tracking and budget changes. Campaign planning happens in short cycles, with clear priorities and a shared backlog, so work does not disappear into a black box. We also help your internal stakeholders, like product, sales and finance, stay aligned with what marketing is doing and why. The outcome is a calm, consistent cadence, less context switching, and a team that behaves like your internal staff while staying on a monthly rolling basis.
