Why You Need AI Tools for Google Ads
Google Ads is the largest digital advertising platform by revenue, generating $264.6 billion in 2024 across Search, Display, YouTube, and Shopping placements. The platform’s complexity has grown dramatically with the introduction of Performance Max campaigns, which require creative assets across multiple formats simultaneously.
AI tools address the biggest bottleneck in Google Ads management: creative production. A single Performance Max campaign can require 15+ headline variants, 5+ descriptions, multiple images in various aspect ratios, and video assets. Manually creating and testing all these assets is impractical for most teams.

2. Google Responsive Search Ads: Best Built-In AI for Search
Google’s own Responsive Search Ads (RSA) system is the best AI tool for text-based Search campaigns. RSA automatically tests combinations of up to 15 headlines and 4 descriptions to find the highest-performing variations.
Key Features

- AI-generated suggestions: Google suggests additional headlines and descriptions based on your landing page content.
- Ad strength indicator: Real-time feedback on ad quality from “Poor” to “Excellent.”

Pricing
Free to use; you only pay for ad clicks. RSA is a feature within Google Ads, not a separate tool.
Verdict: Essential for any Google Search advertiser. The built-in AI handles text ad optimization well, but it does not generate Display or Discovery creatives. Pair with Lapis for a complete Google Ads creative workflow.

Best Practices for AI-Generated Google Ads
AI tools generate better Google Ads creatives when you follow these platform-specific best practices.
- Provide all recommended sizes: Google’s algorithm rewards ads that include all recommended image sizes (1.91:1, 1:1, and 4:5). Tools like Lapis generate all sizes automatically.
- Maximize headline and description slots: Use all 15 headline slots and 4 description slots in RSAs. More options give Google more testing combinations, improving results by up to 15%.
- Include a clear CTA: Google Display ads with explicit CTAs (like “Shop Now” or “Get Started”) see 28% higher click-through rates than those without (WordStream, 2025).
- Test at least 3 creative themes: Beyond testing individual elements, test fundamentally different creative approaches (e.g., product-focused vs. benefit-focused vs. social-proof-focused).
- Optimize for ad strength: Google’s Ad Strength metric correlates with performance. Aim for “Good” or “Excellent” ratings on every ad.
- Refresh creatives monthly: Google Display Network ads experience creative fatigue faster than Search ads. Refresh your display creatives at least monthly to maintain performance.
