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 to your job and probably the personality. One of the biggest headaches of bloggers, copywriters and online, offline workers is that making lots of grammar and spelling mistakes and errors.

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

There’s no any method, right? So you should spell and grammar check of your content to get an excellent article which builds the trust and credibility. How if one of your articles has misspells which change the core message of the document? You could waste your 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 am in the blogosphere since 2012 and have written lots of 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 used to 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 also a few changes which harm the core message of my articles.

Every time I proofread any blog post, I found lots of errors myself. The number of grammatical mistakes reduces in every day as my English knowledge started improving because I write/update blog posts every day.

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

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 to you how to accurately proofread an article to fix spelling and grammatical mistakes.
  2. Hire a Freelancer: Probably the best method to proofread a document. But, it is not an inexpensive process as some proofreading services charge anywhere from $50 to $1000 or even more than that for punctuation, grammar, and spell-check. If you have lots of articles to check their correctness and relevance, so 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 from sites like Fiverr, you can find a few good Freelance editors too. 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 need to pick up one of those and upload your paper to the website. After a few minutes, the online proofreader will start analyzing your article to find the spell, 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 lots of 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 test what I found is that online grammar checker tools (or proofreading tools) could save lots of my valuable time.

Many of my articles here at ProBlogTricks 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 of them are free proofreaders while others are premium or paid proofreading tools, but paid versions have robust features that make your error-full article a complete, quality article that even a 70-year-old grandma can read and understand. So use these proofreading tools to correct spelling and grammar errors.

How to proofread your Article/Blog Post? Best Tips to Remember…

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 to create 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 wrote 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 you have finished correcting, upload content to your online proofreader or use the grammar checking add-on. (I use the Grammarly tool)
  • Don’t approve every suggestion they provide. Remember these online tools and proofreading software work as algorithms command. So some words and tenses could be correct, even proofreaders show them as errors. E. I: Many proofreader programs find that “ProBlogTricks” is a plural noun. But, it’s a singular word.
  • After carefully proofread the article using a grammar and spelling checker tool, recheck the article again manually to make sure there aren’t any inadvisedly missed or added words.

Many bloggers suggest to write the post in a single day and proofread the blog post in another day. Then publish the blog post on a later day. I too recommend this method as more time you dedicate to write 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 the way you present it significantly affects the way people judge it (and the way they judge you).

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

As search engines 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 in increasing search traffic so fast but also build the trust between you and readers plus enhance the credibility of your brand. Neil Patel, the co-founder of KISSmetrics and the owner of QuickSprout hires professional proofreaders to check grammar and spelling errors in his articles. But, you shouldn’t hire proofreaders to correct grammatical errors 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 the suggestions they provide 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.
