Google Ads Campaign Guidelines
A structural overview of policy restrictions, text limits, landing page metrics, and tag specifications required to execute high-converting Google Ads campaigns.
01. Ad Copy Character Limits
To avoid truncation in the Search Engine Results Pages (SERPs), all responsive search ad (RSA) copywriting assets must comply with Google's absolute character limits. Over-limit strings will be blocked by API hooks during account construction.
| Asset Type | Max Characters | Recommended Count | Purpose |
|---|---|---|---|
| Headline | 30 characters | Up to 15 assets | Main title link triggers |
| Description | 90 characters | Up to 4 assets | Supporting pitch text block |
| Display Path (1 & 2) | 15 characters each | 2 paths | URL slug keyword styling |
| Callout Extension | 25 characters | 4-8 active assets | Trust & highlight tags |
| Structured Snippet | 25 characters per value | Min 3 values | Categorized lists (e.g. Services) |
02. Policy & Compliance Standards
Google's automated validation crawler scans ad copies for policy compliance. Violations trigger prompt suspensions or campaign disapprovals. Ensure your creatives align with these primary criteria:
Avoid words guaranteeing performance or specific results (e.g., "Double your profits in 3 days!"). Focus on past metrics and case study statistics (e.g., "Average conversion rate increase of 40%").
Do not capitalize random letters (e.g., "S.A.L.E. Now") or duplicate punctuation (e.g., "Book Your HVAC call!!!"). One exclamation mark is allowed in description text but is prohibited in headlines.
Do not target registered trademarks of competitors directly inside ad text copywriting (e.g. referencing "Carrier Air Conditioners" without reseller permission). Targeting trademarked terms as keywords, however, is allowed.
03. Landing Page Experience Rules
Google evaluates your landing page url destination to assign a "Quality Score" (1 to 10 scale). Higher scores significantly reduce your Cost Per Click (CPC) and improve ad positioning. Optimization rules include:
- Mobile Optimization: Ensure site layouts scale on mobile phones. Up to 75% of service business click traffic is on smartphones.
- Contextual Relevance: Match hero headers to targeted ad keywords. If the ad promises "Emergency Ac Installation," the page must immediately state that service.
- Page Speed (LCP): Ensure the page loads in under 2.5 seconds. High load delays force users to bounce, killing Quality Scores.
- Mandatory Legal Links: The page footer must host links to a Privacy Policy and Terms & Conditions. Google crawler reviews these links to determine business validation.
04. Tagging & Conversion Best Practices
Smart bidding scripts rely on precise conversion inputs to find customers. Bad setups cause automated bids to spend budgets on junk traffic. Our standard setup includes:
- Google Tag Manager (GTM): A single GTM script contains all code tags, eliminating page bloating and script crashes.
- Server-Side Conversion Tracking: Server API endpoints bypass ad blockers and browser privacy restrictions (like iOS Intelligent Tracking Prevention) to accurately map 100% of sales.
- Enhanced Conversions: Feeds encrypted user details (like email addresses or phone numbers) back to Google Ads during lead submissions to align offline conversions to search keywords.
