Advertising consultant: Meta, Google and TikTok campaigns measured on sales
I’m David Callari. I run Facebook, Instagram, Google and TikTok campaigns for companies and professionals who want to grow their brand awareness and turn it into qualified leads and online sales.
100+ happy businesses since 2021, €500k+ in ad budget managed.
David Callari, digital advertiser
I grew up with a 56K modem and watched the web evolve from the first websites to today’s algorithms. I launched my first Facebook campaign in 2014 and I’ve been working in online advertising ever since.
The platforms have changed a lot over the years: interest targeting has become less precise, privacy rules have cut down the data available, and today Meta’s and Google’s algorithms handle much of the audience selection. An effective campaign still needs a clear offer and reliable data, and that’s where my work begins.
See how I work
Business and goals analysis
Before setting up any campaign, we go through your margins, average customer value and your team’s capacity to handle leads together. From these numbers I work out the maximum sustainable cost per lead or sale, which becomes the benchmark for judging results.
Campaign optimization
I monitor campaigns continuously. I pause the ones that don’t deliver, refresh copy and creatives, and move budget to the most profitable campaigns. Every month you get a report with spend, leads generated and cost per lead.
Conversion tracking
I set up Meta Pixel and Conversions API, Google Ads enhanced conversions, GA4 and Consent Mode v2. In my reports I only count real actions as leads: submitted forms, phone calls and WhatsApp conversations started.
Improve your advertising strategy on Meta, Google and TikTok
Put your business in front of potential customers on Facebook and Instagram. Together we create ads built for your audience and measure how many leads and sales they bring in.
Get found by people searching for your products or services on Google. I set up Search, Shopping and Performance Max campaigns based on your goals.
Got a product that looks great on video? With TikTok Ads you reach new customers through short-form content and measure the results of every campaign.
Want to run your own campaigns but don’t know where to start? My training courses give you the foundations to promote your brand online.
