A large account-level analysis highlighted by Search Engine Journal suggests a potential gap between Google Ads’ Ad Strength guidance and actual conversion performance in responsive search ads (RSAs). According to the report, higher-rated RSAs appear to receive more impressions more often, yet lower-rated ads converted better in many cases.

For European businesses that rely on paid search for lead generation or e-commerce sales, the main takeaway is practical: platform recommendation scores should not automatically be treated as a proxy for commercial performance.

What happened

The report cites research by Brad Geddes based on 5,900 Google Ads accounts. The analysis found that Google tends to serve RSAs with stronger Ad Strength ratings more frequently. However, those higher-rated ads reportedly produced better conversion performance only 45% of the time.

The article points to pinning as a key reason. In Google responsive search ads, advertisers can provide multiple headlines and descriptions, and Google automatically combines them in different ways. When advertisers pin specific assets to fixed positions, they reduce Google’s flexibility to mix and match copy. That can lower Ad Strength ratings even if the pinned setup performs better for the advertiser’s actual business goals.

The source reports an apparent tension between Google’s preference for ads that are easier for its systems to assemble dynamically and advertisers’ need for message control, compliance wording, or proven conversion-focused copy structures.

Why it matters for European businesses

Many SMEs and marketing teams use Google’s in-platform scores and recommendations as a shortcut for campaign optimisation, especially when internal PPC expertise is limited. If Ad Strength influences delivery but does not reliably predict conversions, companies may end up optimising toward a platform metric instead of a business metric.

This matters in several practical ways:

• Lead generation: B2B advertisers may prefer tightly structured messaging, including pinned headlines, sector-specific claims, or strong calls to action that convert better even if Ad Strength is lower.
• E-commerce: Online retailers may find that product-specific copy, pricing references, shipping messages, or promotional wording performs better than broader machine-friendly variants.
• Regulated sectors: Businesses in finance, health, legal or other regulated areas may need stricter control over message combinations, which can conflict with Google’s preference for more flexible assets.
• Budget efficiency: If higher-rated ads receive more exposure by default, advertisers may need more active testing to ensure spend is directed toward the variants that actually generate sales or qualified leads.

For European advertisers facing tighter budgets, higher acquisition costs, and pressure to prove ROI, the distinction between platform optimisation signals and business outcomes is important.

Who may be affected

• SMEs using Google Ads without a dedicated paid media specialist
• Marketing teams managing search campaigns around lead generation targets
• E-commerce businesses testing promotional or product-led search ad copy
• Digital agencies responsible for PPC performance and reporting
• Regulated businesses that need tighter control over ad copy combinations

The issue is particularly relevant where conversion tracking is mature enough to compare actual business outcomes rather than relying on click-through rates or platform scores alone.

What companies should consider

• Use Ad Strength as guidance, not as the main KPI. It can be useful for identifying asset variety, but it should not replace conversion rate, cost per acquisition, return on ad spend, or lead quality.
• Test pinned versus unpinned RSAs. If message order matters, run structured experiments to determine whether pinning improves conversion performance despite a lower Ad Strength rating.
• Review impression distribution. Check whether Google is favouring certain ad variants and whether those variants are aligned with revenue or lead quality goals.
• Prioritise business outcomes in reporting. Internal stakeholders should understand that a higher platform score does not automatically mean a better-performing ad.
• Be careful in regulated or brand-sensitive sectors. Where compliance language or precise positioning matters, maintaining copy control may be more important than improving Ad Strength.
• Audit automation assumptions. As search advertising becomes more automated, companies should regularly verify whether machine-led recommendations are improving outcomes or mainly aligning campaigns with platform preferences.

The broader lesson for European businesses is that automation and recommendation systems can be useful, but they still require independent validation. In paid search, the most important measure remains whether campaigns produce profitable conversions, not whether they achieve the strongest in-platform rating.
