What Proofreading Services Involve.
Proofreading occurs at the end of the writing and document editing process, because 56% of polled readers said typos would keep them from buying a product.
Proofreading historically happens when the document is in final form (such as a PDF) and primarily looks for errors like formatting, end-of-line breaks, widows, and hanging words.
Our proofreading services are coupled with copy editing and include the following:
- Review for final grammatical or spelling errors.
- Fact checking.
- Fixing unclear wording.
- Checking links.

What Is Proofreading?
Is Professional Training Necessary For Proofreading?
Professional proofreading is not simply looking for typos, though it does include that. Professional proofreading also involves checking an editor’s edits to ensure they catch every error and that the document adheres to the given style guide. Simply scanning for typos does not require professional training and can be done by a colleague or friend. However, having a professional proofread your content gives it that extra level of polish.Proofreading Fundamentals
Proofreading’s fundamentals include:- Looking for sentence fragments
- Final formatting of line breaks and spaces between words and lines
- Checks for subject/verb agreement
- Check pronouns for common errors such as their/there or your/you’re.
