Top tips to remember when proofreading an article

I think now you have picked up an excellent proofreading tool/service. The next step is to follow a strategic and proven way to proofread your articles. Here are some tips for creating an error-free report.

  • First, write your story. Don’t check for grammatical errors and spelling mistakes at first. You can find them later.
  • After you write the article, get an interval yourself. I usually take one hour or so as it releases the tiredness and helps me feel better.
  • After several hours, you can start proofreading the article manually. Check for contextual and writing style errors. After correcting, upload content to your online proofreader or use the grammar checking add-on. (I use the Grammarly tool)
  • Don’t approve of every suggestion they provide. Remember, these online tools and proofreading software work as algorithm commands. Some words and tenses could be correct, but even proofreaders show them as errors.
  • After carefully proofreading the article using a grammar and spelling checker tool, recheck the article manually to make sure there aren’t any inadvisedly missed or added words.

Many bloggers suggest writing the post in a single day and proofreading the blog post in another day. Then publish the blog post on a later day. I also recommend this method, as the more time you dedicate to writing a post, it will become a quality post.

Conclusion on online proofreading tools

Proofreading is the final stage of the editing process. Content matters a lot, but how you present it significantly affects how people judge it (and how they judge you).

If your blog post or article is filled with weird characters, strange words, and tons of grammatical mistakes, people wouldn’t understand the core message you want to tell them.

As search engines have started using grammar and spelling qualities as ranking factors, and they matter a lot in conversion rate optimization, you shouldn’t ignore the importance of having quality and error-free articles on your website.

Error-less content will not only help increase search traffic so fast but also build trust between you and readers and enhance your brand’s credibility. Neil Patel, the co-founder of KISSmetrics and the owner of, hires professional proofreaders to check grammar and spelling errors in his articles. But, you shouldn’t hire proofreaders to correct grammatical mistakes in your articles.

With the help of these free online Proofreading tools, you can create error-free articles efficiently. But, you shouldn’t always go with their suggestions, as some of them could be incorrect.

So what’s your favorite online proofreading tool? Do you believe that proofreading tools always provide correct suggestions? Share your thoughts in the below comment form.
