When searching and using information from the Internet, ask these questions first:

Is it current?
How recent is the information?
How recently has the website been updated?
Is it current enough for your topic?

Is it reliable?

What kind of information is included in the resource? (Is there data to back it up?)
Is content of the resource primarily opinion? If so, is it balanced to discuss both sides?
Does the creator provide references or sources for data or quotations?

What kind of authority exists?
Who is the creator or author?
What are their credentials?
Who is the published or sponsor?
Are they reputable?
What is the publisher’s interest (if any) in this information?
Are there advertisements on the website?

What is the purpose of the information? (whose point of view?)
Is this fact or opinion?
Is it biased?
Is the creator/author trying to sell you something?
