The free event is designed to increase visitor numbers and spread the benefit of the 3.3 million people who visit the district every year. The day includes a brochure and leaflet swap and a range of presentations and advice sessions in a separate seminar zone.
Tourism representatives from across Greater Lincolnshire will present updates along with presentations on the county's RAF100 programme - celebrating the centenary of the formation of the RAF - plus England's Historic Cities and the county's role in Mayflower 400.
Experts will help with social media, how best to use Google Adwords and Facebook, funding options for the tourism sector, insights into the latest Lincolnshire tourism research and details of a new hotel study.
The Expo will be the first event of its kind and brings together private, public and third sector organisations under the singular aim of maximising visitors to Greater Lincolnshire.
The visitor economy in South Kesteven was calculated to exceed £168m in value in 2016. The value of Lincolnshire's tourism industry overall has risen by more than £300 million over the last five years, reaching £1.37 billion in 2016.
Figures for 2016 show that the county attracted almost three million more visitors than in 2011.
