Congratulations! You’ve been tasked with writing a job description for a role you know nothing about.

We know what you’re thinking, and we’re not supposed to use that language on our blog. If you’re reading this, you’ve probably created plenty of job descriptions in the past, so you know the basics.

But you also know they can always be better.

Learning how to write a job description takes time, effort and practice, but the process is much easier when armed with the right data.

Lucky for you, we gathered cold hard facts from a sample of the top performing job descriptions across our seven markets to determine what the best job descriptions have in common, and how they could be even better.


Essential Elements of A Job Description

There are a lot of elements to consider when writing a job description. To keep things simple, we decided to focus on the 12 most important factors contributing to the success (or failure) of any job description, regardless of industry, job type or company.

  1. Clear Title
  2. Company Description
  3. Responsibilities and Duties
  4. Qualifications
  5. Perks and Benefits
  6. Average Word Count
  7. Average Time on Page
  8. Compensation Information
  9. Opportunities for Improvement
  10. Bullet Points/Formatting
  11. Typos
  12. Call-to-Action


Data Breakdown

These statistics are taken from a sample of the top performing job descriptions across seven major tech markets. Take note from these 10 categories and you’ll be on your way to job description victory.


1. Clear Title

The best job descriptions consistently have clear titles.

built in

92.86% of the job descriptions we reviewed featured a clear title, while 7.14% used vague or ambiguous terminology that wasn’t specific to the role.

With 42.9% of job seekers looking for career opportunities on job boards that use search engine optimization (SEO) techniques, you’ll want to make sure your title is clear, concise and industry specific so the search engines serve your job posts to candidates. If your job can’t be found, it can’t be applied to.


2. Company Description

The majority of job descriptions include information about the company.

built in

68.57% of our sample included a description of the company, whereas 31.43% did not.

This section may take a few extra minutes to write, but it’s worth the effort, as 23% of candidates say that a company description is the most important part of a job description. Consider writing a templated version that can be repurposed whenever you need to write a new job post.


It’s more common to include the company description at the beginning of the post.

built in

Of the job posts that featured a company description, 83.33% were placed the at the beginning of the post and 16.67% were placed at the end.

Rather than taking this as a hard rule, consider testing slight variations of your formatting to determine what works best for you. Including the company description is more important than where you place it.



3. Responsibilities and Duties

Including responsibilities is essential for top job descriptions.

built in

Of the top performing job descriptions, 90% included clear responsibilities and duties.

That’s not surprising given that 49% of people rank job details as the most important part of the job description. In fact, it’s somewhat of a surprise that 10% of the descriptions we reviewed didn’t include this information.

Responsibilities and duties are essential in order for a candidate to understand the role. They also set expectations for the hired employee and can be used as a baseline for performance reviews down the line.


Bullet points are much more common than paragraphs for the responsibilities section.

built in

Of the job descriptions with a section for responsibilities and duties, 87.30% were presented via bullet points while 12.70% were in paragraph form.

Bullet points are easier to scan than long form copy, and may seem like the preferred choice, but given the volume of responsibilities many job descriptions include the format often lacks the desired effect. This is another easy opportunity to test different formats to see what works best for you.



built in

The top performing job descriptions we reviewed included an average of eight distinct responsibilities.

You want to be thorough and clear about the responsibilities tied to this job, and eight is a perfectly reasonable amount, but you don’t need to provide every single detail. Unless there’s good reason, responsibilities like carry laptop to and from meetings and maintain positive attitude can be omitted. If you write too many, job seekers will lose interest. Write too few and the role will appear unclear and you’ll also lose the interest of great candidates.


4. Qualifications

built in

Interestingly enough, our sample of job descriptions also included an average of eight distinct qualifications per job post.

As with responsibilities, you’ll want to strike a balance between providing enough details to inform applicants about the role without being excessive. Whether you go with bullets or paragraphs, keep them short, sweet and easy to understand.


In addition to mandatory skills, many companies included preferred skills.

built in

34.29% of reviewed job descriptions included a section for preferred skills and qualifications in addition to mandatory qualifications, whereas 65.71% only included the mandatory qualifications.

Before you include a list of preferred qualifications, determine how important they are and if it’s worth losing applicants who don’t apply because they don’t meet these criteria. If you do use this approach, make them clear. Cutesy phrases like ‘Bonus Points’ and ‘Show Us What You Got’ may sound fun, but they can be confusing. Make sure the candidate understands how important these qualifications really are.



There were about half as many preferred skills as mandatory skills and responsibilities.

built in

Job descriptions with preferred qualifications contained an average of four additional preferred skills.

This section is lower priority and should have fewer points. If you have more preferred than mandatory qualifications, you may need to take a second stab at defining the role. Make sure to weigh the importance of this section and consider if these should actually be included or if they should simply be taken into consideration during the interview process.


5. Perks and Benefits

More companies did not included perks and benefits, but that isn’t to their advantage.

built in

Of the top performing job descriptions, 42.86% included information on perks and benefits, while 57.14% did not.

This one is surprising, as perks and benefits are essential information. Not including them is a huge mistake, with 61% of people expecting to see benefits packages in job descriptions. Again, this is a section that can be created as a template and used across multiple job descriptions.



6. Average Word Count

Here’s the breakdown of the average word count for the entire job description.

built in

Of the top performing job descriptions we reviewed, the average word count was 457.

The total sample breaks down as follows:

  • 7.14% of job descriptions are between 1-250 words.
  • 54.29% of job descriptions are between 251-500 words.
  • 37.14% of job descriptions are between 501-750 words.

Based on our findings, it’s best to keep your job description in the 250-500 word count rage, but it’s okay to go a little over. This is supported by an earlier study that found a similar trend with the majority of job posts having between 200 and 500 words.



7. Average Time on Page

There seems to be a correlation between average word count and average time on page.

built in

From those top performing examples, the average time a person spends reading a job description page is 1 minute and 41 seconds.

According to an earlier study, the average candidate spends 49 to 76 seconds reading a job description. An average read time of 1:41 represents an increase of 33% on the low end and 106% on the high end. It’s clear that job descriptions which adhere to best practices are much more engaging than their lower performing counterparts.  


Here’s the breakdown of average time on page by word count:

  • 1:29 with a word count between 1-250 words
  • 1:39 with a word count between 251-500 words
  • 1:44 with a word count between 501-750 words

When comparing these results to the average word count, we can can see that the job descriptions with the best time on page were in the 251-750 word count range.


8. Compensation Information

Salary data was uncommon, which is surprisingly uncommon considering job seeker expectations.  



Of the top performing job descriptions, only 1.43% included compensation information, whereas 98.57% did not. For the sake of our study, we did not consider terms like ‘competitive salary’ or ‘high paying’ to as compensation information.

This is surprising given that 74% of job seekers expect to see salary on job descriptions and 61% name compensation as the most important part of the job description. People want to know how your company compares to competitors, and they certainly don’t want to spend five or six weeks interviewing only to find that what you’re offering doesn’t meet their needs.


9. Opportunities For Improvement

Even the best job descriptions have areas that can be improved upon. To that end, we’ve highlighted a few takeaways that would have made this sample even better. Remember to always have your hiring manager or someone who has held this position review the post before publishing it. They might have industry specific information or tips for improvement.



10. Bullet Points/Formatting

We totaled the average number of bullet points per job description to help you adjust different sections without going overboard with bullets.

built in

We averaged the total number of bullet points from our sample, and on average, and entire job description contains 12 bullet points.

81% of people skim what they read online, and bullet points break down content into easily digestible bits.

Remember that the average word count for the entire job description is around 457 for our samples, so it’s important to keep bullet points short and sweet. Lengthy sentences make the bullet points defective, and it’s better to stick with paragraphs if that’s your preference.



11. Typos

Percent of job descriptions with obvious typos

built in

15.71% of the job descriptions we analyzed included obvious typos. We define obvious typos as something a simple spell checker could catch.

Similar to how many recruiters disregard applicants with typos on their resume or application, candidates may come away with a negative impression of your company for not doing its due diligence. Remember to always have someone else read your job description before posting. A second set of eyes is often all it takes to spot errors or typos.


12. Call To Action

By far the majority of job descriptions did not include a call-to-action. Needless to say, we strongly recommend including CTAs.  

built in

Only 20.00% of the job descriptions included a clear Call-to-Action (CTA). For our purposes, we define a clear CTA as information that makes it clear how to apply.

To be blunt, what is the purpose of a job description if candidates don’t know where/how to apply? If you take the time to write a great job description, candidates will read it. But if they get to end and don’t know what to do next, you risk losing out on a great candidate. This is one area that you should customize to the location the job is being posted. Make sure they know where to click or who to email to get the process started.
