The challenge

The company was investing in Google Ads, but returns did not match the budget: cost per click was high and visitors spent little time on the site, a sign that the ads were not 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 restructure

    Reorganised around search intent, with more qualified keywords and negative keyword lists.

  3. More relevant ads and pages

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

  4. Continuous optimisation

    Data-driven adjustments to bids, audiences and budget throughout the year. Discover our paid media management.
