Currency - Is the information dated and is the date appropriate for your topic? Look for published, copyright or last updated date.

Reliability - Is the information something you can trust? Who is the publisher and are there links to their sources?

Authority - Who is providing the information? Look for the author and their credentials.

Purpose and Point of View - Why is this information on the internet? Who is the intended audience, what is the purpose/bias?
