Seven per cent of charities do not have a website, according to research funded by the Economic and Social Research Council.
Carried out last year among 1,000 British charities, the research shows that the majority of those who have a website spend less than £5,000 on the original build and less than £5,000 per year on maintenance and upgrades.
Research author Anna Goatman, said online fundraising was generally a lower priority than providing information. No facility for accepting online credit card donations from users was available on 44 per cent of all sites surveyed. A fifth of respondents said that they were planning to implement such a facility in the next year. But 30 per cent said it would never happen.
William Hoyle, chief executive of the Charities Technology Trust, said: "Most charities have not found the web to be a source of vast numbers of new donors. As part of the marketing mix, however, websites can be the most cost-effective means of collecting income."
Of the respondents, 30 per cent were charities with an annual income between £1m and £5m. Smaller charities with incomes between £10,000 and £100,000 represented 10 per cent; 7 per cent had an income between £5m and £10m.
