What Our Proofreading Services Involve.

Proofreading occurs at the end of the creation 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:

  1. Review for final grammatical or spelling errors.
  2. Fact checking.
  3. Fixing unclear wording.
  4. Checking links.

Every EditorNinja subscription includes copy editing, proofreading, and light line editing to correct for clarity and consistency of copy.

With an EditorNinja subscription, you also receive a primary editor who handles the bulk of your content. You also have a backup editor who gets to know your brand, so we can guarantee that your content gets edited in a timely fashion.

Most documents are returned in one to two business days once they begin editing. Longer documents take a bit longer.

You can always get more content edited per day by adding additional editing lanes or buying a bundle of words in advance to use over time.

If you have a lot of content (80+ pieces per month), let’s talk about a custom arrangement.

We ask every customer to join a shared Slack channel that includes anyone from your side plus the account manager, managing editor, and your primary editor from EditorNinja.

This gets all of us out of email and makes communication asynchronous and seamless.

Proofreading is often maligned as “just looking for typos,” but when copy is not proofread it is infinitely more likely to have errors that kill conversions.

Proofreaders make $10-$100 an hour depending on how experienced they are.

EditorNinja has professional editors who are trained to be expert proofreaders and copy editors. You pay one monthly price and get your content edited.

No more worrying about people management or paying freelancers on time. We take care of all of that.

What Is Proofreading?

Proofreading is the final step of the editing process, where an editor reads through a fully edited piece to identify any last mistakes. At EditorNinja, we cover this with our double QA process, where the editor makes a copy of their edited piece, accepts all of their changes, and uses machine learning and the human eye to catch any final mistakes before sending it back to their managing editor for final QA. The managing editor receives the edited piece and applies their own QA process.

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:
  1. Looking for sentence fragments
  2. Final formatting of line breaks and spaces between words and lines
  3. Checks for subject/verb agreement
  4. Check pronouns for common errors such as their/there or your/you’re.
Proofreading sometimes blurs in with copy editing, but they are two distinct parts of the editing process. Proofreaders will often read a document out loud to ensure it reads naturally, as this also helps catch any errors.

How Much Does A Proofreader Cost? (Proofreader Salary)

According to Payscale, the average annual salary for a proofreader ranges from $26,000-$70,000 in the United States.  Salary varies based on experience and the company you work for. A freelance proofreader can expect to make between $12-$30 per hour based on types of clients and turnaround speed, with an average of $18.67 in 2022. According to our data, 65% of freelance editors, including proofreaders, bill by the word instead of by the hour or the project, as billing by the hour penalizes them for working quickly and by the project penalizes them for taking on more significant projects.
