Dynamic Search Ads (DSA): Common Issues and How to Fix Them
Dynamic Search Ads automatically match user searches to your website content, generating headlines and selecting landing pages dynamically. When DSAs underperform, the root cause is almost always poor site structure, weak targeting, or lack of control.
1. Poor Website Content or Structure
Problem
- Google relies entirely on your website content to generate DSA headlines
- Thin, outdated, or poorly structured pages lead to irrelevant ads
Fix
- Create clear, dedicated product or service pages
- Use descriptive, keyword-rich page titles and meta descriptions
- Organize content into logical categories for easier crawling
2. Broad Targeting / Catch-All Campaigns
Problem
- Targeting the entire website causes low CTR and irrelevant traffic
Fix
- Create separate DSA ad groups by category, service, or product type
- Exclude non-commercial sections like blogs, careers, policies
- Use page feeds for tighter control over landing pages
3. Irrelevant or Weak Ad Copy
Problem
- Dynamic headlines may not fully match user intent
- Poor descriptions reduce CTR
Fix
- Write strong static descriptions that sell the click
- Highlight benefits, offers, and clear CTAs
- Tailor descriptions to each category or service group
4. Missing Negative Keywords
Problem
- DSAs can trigger ads for irrelevant or research-based queries
- Wasted spend from poor search matches
Fix
- Build a robust negative keyword list
- Review Search Terms reports frequently
- Apply category-specific negatives where needed
5. Poor Bidding Strategy
Problem
- Manual bidding often overpays for low-quality traffic
- Low bids reduce auction competitiveness
Fix
- Use Smart Bidding once enough conversion data exists:
- Target CPA
- Maximize Conversions
- Target ROAS
- Adjust bids based on category or page performance
6. Not Using Ad Extensions
Problem
- DSAs without extensions appear smaller and less compelling
Fix
- Add sitelinks, callouts, structured snippets, and promotions
- Match extensions to the targeted category or service
7. Targeting Low-Value Pages
Problem
- Low-intent or informational pages attract clicks but don’t convert
Fix
- Exclude low-value pages using URL rules or page feeds
- Focus DSAs on high-converting or high-margin pages only
8. Not Monitoring Search Terms
Problem
- Irrelevant queries slip through if not reviewed regularly
Fix
- Check Search Terms reports weekly
- Add negatives for irrelevant or low-intent queries
- Refine page targeting based on real conversion data
9. Weak Landing Page Experience
Problem
- Poor UX leads to low conversion rates even with good targeting
Fix
- Ensure fast load speed and mobile optimization
- Match landing page intent to the user’s query
- Place a clear CTA above the fold
10. Poor Campaign Structure
Problem
- Mixing unrelated categories dilutes performance and insights
Fix
- Create category-specific DSA campaigns
- Separate high-converting and low-converting products/services
- Allocate budgets based on conversion potential
Quick DSA Troubleshooting Framework
- Low CTR: Improve page relevance, descriptions, and extensions
