Nash Marketing Labs manages ad spend on Google Ads, Meta Ads, TikTok Ads and LinkedIn Ads, and audits accounts run by others. The work is organised by platform, by business type and as a standalone audit. We are based in Spain and work with clients in both Spanish and English.
This page exists so you don't have to guess which service fits. Each block says what the service includes, who it is for and where to read about it in full. If you would rather start with numbers than with services, our free tools run in your browser without storing any data, and the viability audit maps out your account's potential using your own figures.
Campaign management by platform
- Google Ads agency — Search, Shopping, Performance Max and YouTube. This is where the most budget is lost while looking efficient: brand cannibalising non-brand, PMax with no control over where it serves, and conversions counted twice. For accounts that already spend and don't know which part of the result is incremental.
- Meta Ads agency — Advantage+, prospecting and retargeting with server-side measurement and CAPI. For accounts where the ROAS in the dashboard doesn't match what the business sees, usually because of the attribution window and duplicated events.
- Paid media agency — the full service, with a channel mix decided by data rather than habit: Google, Meta, TikTok and LinkedIn under a single profitability criterion.
Services by business type
- Paid media for ecommerce — large catalogues where every product leaves a different margin. We scale on margin, not on platform ROAS, with the catalogue classified by profitability and scaling potential.
- B2B paid media — long sales cycles, where a cheap CPL is almost always a lie. The goal is a qualified opportunity in the CRM, not a form fill.
The team is based in Alicante, Spain. Account management is remote, so where you are matters less than whether your numbers give the platforms something to learn from.
Audit: the cheapest way in
A Google Ads audit is an analysis of your account that doesn't end in a list of best practices, but in a figure per problem: how much it costs you each month and in what order it makes sense to fix it. It doesn't require switching agencies or granting write access.
It is the natural first step if you suspect money is leaking but can't prove it, or if you want a second opinion on what your current provider is reporting.
What every service includes under the hood
Whichever service you hire, the same infrastructure sits underneath, at no extra cost:
- Tracking: server-side measurement, GA4, Consent Mode and CAPI. If measurement is broken, everything else is noise.
- BI: ad platforms, analytics and sales unified in our own data pipeline with daily reporting.
- Catalogue classification: every product ranked by profitability and scaling potential.
- Creative and Automation: AI-assisted creative production and automation between ad platforms and CRM.
- Speed: site speed, which decides how much of your paid traffic actually gets to convert.
The methodology is always the same, and always in this order: model the business, calibrate measurement, visualise the data, optimise against business metrics and only then scale.

- The B2B paid media audit checklist: ten points to mark yes or no on your own account, where every no is an active leak.
Frequently asked questions
Which service do I need if I'm not sure?
If the problem is a specific platform, that platform's service: Google Ads or Meta Ads. If the problem is the business (scaling an ecommerce store with different margins per product, or generating quality B2B opportunities), the service for your business type. If you want to know what is going on before committing, the Google Ads audit.
Is there a minimum contract term?
We don't work with long lock-in periods. The commitment runs the other way: the first months carry the heaviest workload, because that is when measurement is calibrated and the campaign structure is rebuilt, and that is where we show whether the service pays for itself.
Do you only work with clients in Spain?
No. The team is based in Alicante, Spain, where we also meet clients in person, but account management is remote: we work across Spain and also run accounts outside the country, in Spanish or English.
What is the minimum ad spend?
There is no published figure, because it depends on margin and sales cycle: a high-ticket B2B account needs less spend than a low-ticket ecommerce store for the service to be profitable. The viability audit gives you that reference with your own numbers in five minutes.
Not sure which one fits?
The viability audit uses your numbers to tell you which service makes sense in your case and how much headroom your account has. Free, no strings attached.
