There is so much hype and theory surrounding hiring, but perhaps the most important aspect to focus on is your job posting. It's the first thing any applicant sees and as they say, first impressions matter.

When it comes to talking about your company and the position you have available, write in a tone that is equal parts personable and professional. Put yourself in the applicant's shoes -- why should they want to join your team? The tone of voice you use for the posting is key to the type of people you will attract.

Our company recently released a job posting without heeding this study's advice. Upon adjusting and re-writing it to fit these tips, our flow of applicants went from a trickle to a steady flow. It's not to say that these tips will work for everyone, but knowing that they could be a make or break situation is pretty helpful.

LinkedIn compiled this research by reviewing 4.5 million job postings in the US and UK from 2016 to 2017. So, what are the key takeaways?

1. Keep your posting short.

By getting your posting across in less than 300 words, you have a higher chance of more applications per views. Their studies also show that more than 50 percent of job postings are viewed on mobile, which lends to a better experience. Make sure you don't skimp on important details, including compensation, qualifications, and daily responsibilities.

2. Post your job earlier in the week.

Most job applications are submitted on Monday when people are motivated for some change. In addition, over half of all the week's total job views and applications take place Monday thru Wednesday, so if you're thinking of announcing a new opening, veer away from Friday.

3. Use gender-neutral terms.

It turns out that your vocabulary directly affects who applies to your job. Make sure you are neutral when writing up your description so that you can get an equal pool of applicants. 

For example, refrain from using words like "superhero",  "rockstar", or "hacker" from the job title and stick with traditional descriptions like "engineer" or "project manager". Not only is the latter more friendly to any type of candidate, but it also will do better SEO-wise when a potential candidate searches for your job. 

In addition, aim to only include must-haves in your job requirements and limit the number of nice-to-haves. Studies have shown that men are more likely to apply for jobs when they meet 60 percent of qualifications, whereas women hesitate unless they meet 100 percent of qualifications.
