Paid media and measurement, run as one job.

Paid media and measurement, run as one job.

I'm Nir Klein. I run paid media and measurement for e-commerce and serious lead-gen businesses. One person owns both sides, because separating them is where most performance problems begin.

What I do

My core work is paid media and measurement, run together. I manage Google Ads and Meta campaigns — strategy, structure, bidding, creative direction, day-to-day optimization — and I own the tracking underneath them. GA4, GTM, server-side events, Meta CAPI, offline conversion tracking, CRM integrations. One person owns both sides, because when those two jobs are managed separately, the reporting drifts and no one owns the gap between what the platforms claim and what the backend actually shows.

Before I build anything, I need to understand the business. The model, the economics, the offer, the conversion funnel, the customer journey. For lead-gen clients: what the sales process looks like and where qualified leads are being lost. Whether the current tracking is telling the truth about any of it. Most paid media performance problems aren't in the ad account — they're upstream: a conversion rate issue, a tracking gap, an offer that doesn't convert, a sales handoff that's dropping real pipeline. They look identical on the dashboard. Figuring out which problem I'm actually dealing with is what determines whether the work moves the business or just generates activity.

As part of most retainers, I provide ongoing performance reporting — weekly or monthly — that connects platform data to backend results. A plain-language read of what's happening and why, not a slide deck of impressions.

I also take on standalone tracking work: audits, GA4/GTM setups, server-side implementation, offline conversion builds. Real deliverables with specific findings and fixes.

I don't do SEO, content, organic social, or email. Those need their own specialists. If you need them, I can point you toward people I trust.

How I Work

You work with me directly.

I start with the business, not the campaigns.

Media and measurement stay connected.

In the account every week, close to the business. I'm in the accounts, in the data, and in contact every week. Not monthly. If something changes — a performance drop, a tracking anomaly, an external factor affecting the numbers — you hear from me directly. I don't wait for the scheduled call.

Honest reads, plainly delivered. If something's working and I understand why, I'll tell you. If something isn't working, you'll hear that too — early, in plain language, before it gets expensive. I don't dress up mediocre results in good-looking dashboards, and I don't hide bad news in footnotes. When I think we should change course, I say so.

Most of my engagements are retainers. Performance work compounds. The decisions you make in month six are better than the decisions you make in month one, because the context is richer and the data is cleaner. Retainers are the model because that's the shape that tends to produce real results.

About me

What I find most interesting about this work is the diagnosis — understanding what's actually limiting a business's paid performance before deciding what to change. Sometimes that's the account structure or the campaign strategy. Sometimes it's the conversion funnel or the offer. Sometimes it's the measurement, and the business has been optimizing against signals that don't reflect real outcomes. I build the media approach around what I find, which is why every engagement starts with questions rather than a plan.

I've been running paid media and measurement for over a decade, across e-commerce and lead-gen, in markets where performance is measured on revenue and qualified pipeline — not reach or impressions. I work independently, and have for most of that time. That's a deliberate choice, not a default.

I work best with clients who are close to their businesses, direct about what they need, and interested in understanding the numbers — not just receiving them. The best conversations I have with clients tend to happen when there's enough shared context that we can talk about the actual problem, not just the metrics. I communicate directly, keep things as simple as the work allows, and tell you what I actually think — including when I think we should change something that isn't working.

I take on a limited number of engagements at any one time. Close involvement is only possible when the client list is manageable.

Work with me

If you're trying to figure out whether this is the right fit, the best next step is a short call. No pitch, no deck — just a conversation about what you're working on and whether what I do is relevant to what you need. If it's not, I'll tell you that too.

Who this is for

This works well for:

— E-commerce brands doing meaningful revenue on Meta and Google, where ROAS reporting doesn't match the backend and tracking quality is a live problem. — Serious lead-gen businesses — services, B2B, finance, legal, real estate, high-ticket — where a single qualified lead is worth enough that bad attribution materially destroys the economics. — Established businesses spending $10k–$100k/month on paid media that want a senior specialist close to the work, not an agency overhead structure wrapped around a junior operator.

This isn't the right fit if:

— Your media spend is at a level where the engagement can't pay for itself from real results. — You're looking for the cheapest option. The market has plenty of those. — You need a full-service team — creative production, SEO, social, email — under one roof. — You want a vendor who manages the account at arm's length and sends a monthly report. That's not how I work, and trying to run it that way wouldn't produce results worth paying for. — You need a large team, formal reporting structures, and a 40-slide onboarding deck.
