Do you know that people would stop reading your document,books,novels,articles and business proposal. If filled with error. The benefits of proofreading document is; to check the word usage, punctuation, grammar, capitalization style, avoid repetition of words, phrases, or ideas and spelling error.
Not to be rude, but you should have proofread this post.
Proofreading is the process of examining the final draft of a document or text — after it has been edited — to ensure there are absolutely no errors. A proofreader will review for spelling errors, punctuation errors, typos or incorrect use of regional English (i.e. ensuring that you’re using American English or British English when necessary).
For important proofreading, you will want to hire an experienced freelancer with the the ability to find even the smallest grammatical errors that others might normally dismiss. Hiring a proofreader is particularly helpful if you’re not confident in your writing, or if English is not your first language.
While proofreading can be done electronically — for example, using track changes in Microsoft Word — it is just as often done on a printed version (also referred to as a “hard copy”) or PDF. In this case, you’ll need to familiarize yourself with proofreaders’ marks, a collection of symbols and shorthand to indicate corrections.
