It's a Must for Web Writers

Learn the difference between "its" and "it's." Using the wrong word can quash your credibility.

"Its" is a possessive ("It wagged its tail"). "It's" is a contraction ("It's [it is] snowing outside.") If you'd rather not learn the grammar, just remember this: his, hers, its. They're all possessives; none of them has an apostrophe.
