In Jan this year (2024), we changed the Google Ad campaign type to a Dynamic Search campaign to focus on more engaged users. We’re now seeing engagement times much closer to the engagement times we’ve had from organic search traffic.
I recommend the Google Ad budget be reduced and more effort/budget be directed toward social media ads (Facebook and Instagram perhaps) as well as SEO efforts around link building and content development.
SEO strategy
Increase focus on sharing authoritative content through the website and related channels.
