Paid search can work well even for very expensive products because the people clicking those ads are usually further along in their buying decision. Someone searching for a high-end product already has interest, so converting them into buyers is more realistic than with cold audiences. The cost per click may be high, but if even one sale covers months of ad spend, the campaign still makes financial sense. Expensive products just need longer sales cycles and strong landing pages. Have you tried running paid ads for a high-ticket product before?
