How to Improve Ad Relevance Score & Reduce Costs

Introduction

Facebook advertising works best only when your ads reach the right people and engage them. Many campaigns fail not because of low budget, but because of low relevance score. When Facebook sees users interacting with your ad, the platform rewards you with lower costs and wider reach.
This guide explains how to improve your ad relevance score and significantly reduce ad spending—while increasing clicks, conversions and ROI.


What is Ad Relevance Score?

Ad relevance score (now known as Ad Relevance Diagnostics) tells how well your ad matches your audience’s interest and behavior.
It is measured using three factors:

Relevance DiagnosticWhat It MeansGoal

Conversion RankingLikelihood of conversion vs competitorsImprove targeting and landing flow

A higher score = cheaper ads + more results ✔


10 Proven Ways to Improve Ad Relevance Score & Reduce Costs

Target the Right Audience

If you show your ad to everyone, nobody connects with it deeply.
→ Use narrow interest + location + behavior targeting.
→ Create custom and lookalike audiences.

Use High-Quality Creative & Visuals

Images & videos decide whether people stop scrolling or skip.
✔ Use bold text, clear visuals, product close-ups.
✔ Avoid blurry, overcrowded designs.

Write Clear, Benefit-Driven Ad Copy

People respond when they see value.
Use short lines, clear CTA & direct benefit statement.

Example:
“We sell security fencing.”
“Secure your property 10X better with long-lasting fencing!”

Align Ad Message With Landing Page

Your ad promise and landing page experience must match.
Mismatch = bounce → low relevance ranking.

A/B Test Different Ad Variations

Test one change at a time:
Headline
Image vs video
Call to action
Audience sets

Small changes often drop CPC drastically.

Use Retargeting to Increase Click-Through

People familiar with your brand respond faster.
Retarget website visitors, Instagram engagers, video viewers.

Improve Engagement with Strong CTA

CTA should push users to take action immediately.
Examples:
• Learn More • Book Now • Get a Free Quote • Shop Now

Use Social Proof to Build Trust

Reviews, testimonials and real photos boost relevance.
✔ Use UGC (User Generated Content)
✔ Show before/after results
✔ Add rating badges

Optimize Ad Frequency

Too many repeated impressions = fatigue = negative feedback.
Try to keep frequency below 2–3.
Refresh creatives when frequency increases.

Monitor Metrics & Optimize Regularly

Watch CTR, relevance diagnostic, cost per result.
Turn off poor performers and scale winning ads.


Conclusion

Improving your Facebook ad relevance score is the smartest way to lower advertising costs without increasing budget. With strong creatives, targeted audiences, and continuous testing, your ads will perform better, convert faster, and deliver more ROI.
