grammar and spelling check free online

It doesn’t matter what your job or position is. If you are not good at writing error-free articles, it influences your job and probably your personality. One of the biggest headaches for bloggers, copywriters, and online and offline workers is making many grammar and spelling mistakes and errors.

Yes, writing error-free articles is a tough job. But it doesn’t mean you cannot write quality content with fewer grammar and spelling mistakes. There are lots of ways to check grammar and spelling. If you don’t edit and proofread articles, how can you ensure that your literature is grammar and spelling-free?

There’s no method, right? So you should spell and grammar checks your content to get an excellent article that builds trust and credibility. What if one of your articles has misspells that change the core message of the document? You could waste valuable time and lose a customer or even an existing customer, right?

So in today’s post, I will show you how to improve your spelling and grammar with proofreading. This is especially applicable to you if English is not your mother language.

Why Should You proofread your articles?

I have been in the blogosphere since 2012 and have written many articles and documents. One fundamental question I got in earlier days is how I can check grammar and spelling errors and mistakes in my papers. I think you should also have this issue. In those days, I proofread manuscripts, essays, articles, dissertations, and online documents such as white papers and eBooks by myself without anyone’s help.

But what happened? I found hundreds of spelling errors, grammar mistakes, and a few changes that harm my article’s core message.

Whenever I proofread any blog post, I find many errors myself. The number of grammatical mistakes reduced daily as my English knowledge started improving because I wrote/updated blog posts daily.

That’s when I started to find a suitable method to proofread articles and blog posts. I found a few best ways to correct and check my grammar in that period.

4 Ways to Proofread Any Article

  1. Proofread Yourself: One of the most used methods of checking grammatical errors and finding misspells is self-proofreading marks. But, many people don’t use this method properly, so they end up having lots of grammar and spelling errors in the article. One problem with that is human brain needs to relax, unlike robots. You need to practice your brain to get the attention of the whole article and make proofreading marks properly. I will later explain how to proofread an article to fix spelling and grammatical mistakes accurately.
  2. Hire a Freelancer: Probably the best method to proofread a document. However, depending on the freelancer, you might end up paying a lot more than the content itself! If you have many articles to check their correctness and relevance, this is not the best method you must go with as they could cost hundreds of thousands of dollars. To your notice, you can hire a professional proofreader from Elance and oDesk. Also, there are lots of proofreading websites online. You can search on Google to find a few of them. Many of those sites have professional proofreaders who have a good knowledge of their languages. Also, you can find a few good Freelance editors from sites like Fiverr. But, they only proofread a few texts from the article. You need to pay extra fees to get more words checked.
  3. Use Online Proofreading tools: This is the most comfortable and cheapest way to check a document’s grammar and spelling mistakes. There are lots of Online Proofreading Tools. You must pick up one of those and upload your paper to the website. After a few minutes, the online proofreader will analyze your article to find the spelling, grammatical and punctuation errors. Many of those tools will suggest treatments for those blunders. You can choose what letters, words, and grammar suggestions are too right and go up with them.
  4. Use an Offline Proofreading Software: There are many auto-grammar and sentence correction software for Windows and Mac. Not only that, but you can also find a few grammar-checking apps for your Android and iPhone. This offline proofreading software has a database that includes millions of words and hundreds of grammatical rules. As many languages use to change and could add lots of new words every day, using offline software to proofread is not a 100% perfect choice.

I followed all of the above methods, despite hiring a freelance proofreader to check grammar and spelling mistakes in my blog posts.

At the end of the test, I found that online grammar checker tools (or proofreading tools) could save lots of my valuable time.

Many of my articles here at Pitiya exceed the 2000 word count. To name a few, Semrush review, Long Tail Pro review, Tumblr SEO tips and tricks, and Best SEO Tools (and the article you are reading) have lots of words and sentences. So I wanted to check my sentence for grammar errors.

In fact, English grammar matters in marketing and conversions. If no one can understand the message that you want to indicate, will anyone buy your products? Not anyone, right?

Also, Bing already uses grammar quality as a metric to rank web pages on SERPs. So you should improve your writing skills in English to increase organic traffic.

As I said, I have used many online proofreading tools. Many are free proofreaders, while others are premium or paid proofreading tools. However, paid versions to have robust features that make your error-full article a complete, quality one that even a 70-year-old grandma can read and understand. So use these proofreading tools to correct spelling and grammar errors.

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.
