All you have to do is look at some of your friends’ Facebook posts or in the comments section of a news site like Yahoo to know that there’s no shortage of people writing on the Internet who lack an understanding of basic grammar. While nobody likes the pushy grammar police, if you want to be taken seriously, you should make an effort to reduce mistakes in your writing.First of all, write your posts in MS Word (or whatever you use) and spell check. When you see that little red line, take the time to fix that word it's underlining. The little green line is a grammar mistake. It’s not 100 percent accurate, but it might point you in the right direction.
Aside from spelling, the most common mistakes I see on the Internet are punctuation mistakes, especially the apostrophe. Plural words don’t use an apostrophe. I like dog’s is a mistake. The apostrophe is used to indicate possession (my dog’s nose) or a contraction (I can’t swim). Sometimes this is confusing, because it’s is a contraction while its is a possessive pronoun.
Other punctuation marks, such as the comma, are a lot more complicated, not to mention all the endless grammar and formatting rules. If you are serious about your blog and your writing, then take some time to do some research. A good website to check rules of speech is Writer’s Block. Maybe read a lesson a week and apply it to your writing.
The most important thing is to simply read what you have written before you publish it. It takes a long time to develop perfect grammar. Like most things in life, it is a process and awareness is the first step.
