The Liverpool Convention Bureau and Visit England campaign increased web traffic to www.visitliverpool.com by 120% within 54 days of broadcast, while the number of Facebook 'likes' and Twitter followers grew by 40%, according to data from the Liverpool City Region Local Enterprise Partnership.
The 10-second ad, which formed part of Visit England's national Great campaign, ran for a month in April and featured Liverpool's skyline, St George's Hall and the Museum of Liverpool. It was aired in the Granada region. An online version of the commercial on the Visit Liverpool website has been viewed 100,000 times.
Carol O'Reilly, manager at the Liverpool Convention Bureau, said: "TV advertising is obviously a powerful tool and we are delighted to have featured so heavily in this campaign with Visit England.
"Not only has this exposed the wider Liverpool City Region to those unfamiliar with the destination, it has reinforced the city's status as one of the leading places to visit in the UK for both business and leisure visitors."
