Google Ads on €12 a day: 4,330 clicks in six months and a cost per click of €0.46
Inventos Eureka helps turn an idea into a patent. It had a live campaign that was spending without measuring. We put it to work on the same budget.

In shortThe three key points of this case
The account had ads, but wasn't measuring conversions. Without consent mode, Google couldn't see the forms.
Before touching the bids, I fixed the measurement. Without data there's no strategy, just faith.
Between January and June 2025 the campaign racked up 4,330 clicks, up to 882 in a single month.
A campaign that spent without knowing what it brought in
The account had ads, but wasn't measuring conversions. Without consent mode, Google couldn't see the forms.
And the budget was small: €12 a day against the 24 the platform asked for. Every euro had to count.
Measure first, bid later
Before touching the bids, I fixed the measurement. Without data there's no strategy, just faith.
- Competitor analysis — what competitors were advertising and with which words.
- Measurement sorted — Google Tag Manager, consent mode and enhanced conversions, with support from Google.
- Keywords watched daily — “cómo se patenta una idea” and “patentar una idea” (how to patent an idea) as the core, with CTR above 6%.
- Client summary — clicks, cost and conversions explained in an email, no dashboard to decipher.
Every euro, two clicks
Between January and June 2025 the campaign racked up 4,330 clicks, up to 882 in a single month. The CTR was 5.89% and each click cost between €0.41 and €0.49.
Analytics recorded at least 17 form submissions and five more contacts. All on €12 a day.
