hi there, we usually use unbounce. Mostly medical and legal sites. We're not allowed to show them to other clients, but i can show you several that we've made outside unbounce like
[login to view URL]
[login to view URL] << event already ended
[login to view URL]
[login to view URL]
[login to view URL]
[login to view URL] << MLM site
in addition, we also handle SEO and FB ads budgeting + banner design ( example: tvhobby has over 31 different ads targeting 31 different demographics and interest groups, we monitor their performance rate and switch it with a new one when it drops )
