Dynamic text depending on query parameters

Hello, it would be great to make text variable depending from query parameters in URL. For example the H1 Title of my website is « Restaurant » if the user write this URL : www.restaurant.com And my H1 title is « Restaurant London » if the user write this URL : www.restaurant.com/?location=london It would be allow us to create better and dynamic landing pages for Google Ads. Unbounced is one of the leaders in landing page creation and they offer this functionality. Thank you for your votes Pierre
