A survey of 25 local authorities, which included county councils, shire districts and unitary authorities, showed that councils have paid less attention to web provision for companies than they have for citizens.
The study by local authority IT managers group Socitm will be expanded to a nationwide survey.
"Based on the pilot sample, web provision for business is behind that now available for citizens," said Martin Greenwood who is managing the research for the Working with Business National Project, an e-government initiative funded by the Office of the Deputy Prime Minister.
"We also found information for business is fragmented across most websites. This makes it more difficult to track down the information than if it was brought together in one section."
