The challenge

The company was investing in Google Ads, but the return didn't match the budget: cost per click was high and visitors spent little time on the site, a sign that the ads weren't attracting the right audience. The goal was to reach more qualified people while spending less.

What Nume did

  1. Account audit

    Analysis of campaigns, keywords, search terms and conversions to identify wasted spend.

  2. Campaign restructuring

    Reorganization by search intent, with more qualified keywords and negative keyword lists.

  3. More relevant ads and pages

    New ad copy and alignment between ad and landing page, increasing relevance.

  4. Continuous optimization

    Bid, audience and budget adjustments based on data, throughout the year. Discover our paid media management.
