ChildLine has redesigned its web site to make it more appealing and accessible to children seeking advice and information.
The new site contains a child-friendly search engine that allows children to find information using their own words, including misspellings and colloquialisms.
It also features interactive elements such as a quiz and a multiple choice cartoon discussing bullying.
The charity hopes the internet initiative will also make it more accessible to boys, who at present only make up a quarter of its callers.
Carole Easton, chief executive at ChildLine, said: "Children are turning to the internet more and more for information. We hope that by improving the web site we can reach out to more of those boys who need our advice but don't feel comfortable calling our helpline."
The charity has also teamed up with AOL to produce a safety leaflet and last year set up a chatroom enabling children to support each other.
