Making Ads Stand Out
Compelling headlines, engaging copy, clear CTAs. Responsive Search Ads (RSAs): Provide multiple headlines and descriptions; Google’s AI tests combinations and optimises for performance.
Conversions
What counts: Order, enquiry form, PDF download, rate request. Tracking: Set up conversion actions in Google Ads; use Google Tag Manager for implementation.
Value of click = Conversion rate × Value per conversion. E.g. 15% rate × £40 sale = £6 per click.

This is the consolidated reference for retargeting across all channels. Module 09 (E-commerce) links here.
How It Works
Track behaviour on your site; show targeted ads after visitors leave. Define audience (e.g. added to cart but didn’t purchase; viewed pricing page but didn’t sign up). Create focused ads with relevant offers.

Cart abandoners, product page viewers, pricing page visitors, past customers
Set up tracking
Google Ads remarketing tag, Meta Pixel, or platform-specific tracking
Create targeted ads
Personalised messaging based on what they viewed or did
