How Good Writing Affects Your Business

You already have social platforms with a huge following and website videos that get a good number of views. With all the high-tech tools that you have and trendy marketing tactics in place, do you really have to invest time and money in good ol’ grammar?

Turns out, a company’s language efficiency — or lack thereof — is more important than you think. In fact, 59% of polled UK consumers admit to avoiding businesses with blatant spelling and grammatical errors in their websites or marketing materials.

Here are 5 ways poor grammar can affect your business:

Lowers your search rankings. Google only puts the most relevant pages on its search results. Business pages that exude authority and the closest text match relevance top its list. If your content is riddled with misspellings and grammatical errors, you’re likely to end up at the bottom. Here are 3 other ways to get a higher website ranking in Google.
Diminishes your credibility. Credibility is currency in business. It takes years of hard work to build and a poorly conveyed message to break. Grammatical errors in written and verbal communications will instantly make your authority hit the floor. The key to always put your best foot forward? Keep the best grammar checker app in your pocket.
Pulls the plug on prospects. Imagine doing research about a company. You check their official business website and read through the content, only to be greeted with misspellings, misused punctuation marks, and sentence fragments. Poor grammar shows sloppiness and can quickly cast doubts in your reliability as a business. It’s a quick way to turn prospects away.
Misleads or confuses people. Whether you’re closing a deal with a client, pitching a proposal to an investor, or negotiating with an investor, you need to word all your business documents accurately. When you don’t keep your grammar in check, you run the risk of getting into mix-ups.
Sidetracks readers. You should always give your readers a good read. For one thing, people have a shorter attention span if your content is uninteresting or poorly written. For another, grammatical errors can take away from what your message. Even worse, people might share your poorly written content, thus drawing flak to your brand.

How to Strengthen Your Communications and Content Further

Remember that grammar checkers are just tools for polishing the content you already have. To maximize it, you need to submit relevant and engaging content first.
This is where having a Content Writer Virtual Assistant or Content Creation team comes into play.

You need content writing specialists to research, write, and edit your communications and content for multiple platforms. Grammar checkers will keep your team in check and ensure everyone follows the same branding style and tone consistently.

Hire a content writer from 20four7VA or build your content marketing team as your business grows. There are many free grammar checkers made to scale and 20four7VA offers scalable virtual staffing solutions to grow with your team.

Grammar is important to both professionals and entrepreneurs. It can boost your authority in your niche, strengthen your ties with clients, and help you capture the essence of your band. Work with content specialists to create your brand content. Then, find the best grammar checker software or app that best suits your business.
