Correct spelling online is critically important. Especially if you are attempting to sell something. Incorrect spelling can leave a bad first impression and devalue your image. Matt Cutts recently posted about spell checking your website and offers some insight on the subject. I also wrote about a free Spell Checking tool that integrates into Internet Explorer and allows you to easily check your spelling inside any form while online. This is a great tool for forums, comments, and blogging. Although sometimes a misspelling can be a typo, your readers will never know the difference. If it’s important for you to come across as professional and intelligent then make perfect spelling a habit of yours.
