If you are a blogger, then you should remember that your words represent who you are. It is important to present yourself well, and that is why it is necessary to avoid common grammar mistakes. In fact, avoiding common grammar mistakes is an important part of building your online reputation as a blogger. I would like to list a few grammar mistakes that can be easily avoided:

-Improper use of it’s and its. It’s is a contraction of it is or it has. Its is a possessive pronoun that shows ownership. Use it’s only if it can be substituted with it is or it has.
-Improper use of that, which, and who. Only use which when referring to things. Use who when referring to people. That usually refers to things; however, in some cases, it may refer to a class or type of person. Generally, you should use which only for non-restrictive clauses, and that for restrictive clauses. Some argue that if a sentence already uses the word that, then you may substitute that with which. Try to remember that which adds a useful, but not grammatically necessary, piece of information. If you want to make sure that you should use which, it might help to imagine by the way following every which.
