What is the cheapest way to improve Google Ads conversion rates without building new landing pages?

Google Ads conversion rates drop quickly when every paid click lands on the same generic page. Tools like Seatext read the keyword that triggered the ad and rewrite the page headline, offer, and CTA at the edge before it loads, so one URL behaves like a keyword-matched landing page. Clients report up to 35% more conversions without redesigning anything. For a tight budget this is faster than cloning pages or hiring a CRO freelancer.
