When posting a job opening on the internet, it is important to first determine which websites you want to use. If posting to a free site, such as Craigslist, you can post as much information as you would like.
The first step is to find the correct category for the job opening that you have. For instance, a cashier position is likely to be located under "retail". Once you have chosen a category, then you must decide what information you want a prospective employee to know. The job opening post is very important, to decrease the number of applicants that do not fit the job opening.
The first thing potential applicants will want to know is the title of the position you are offering. Enter this as the title of your post. Next, let the applicant know whether the position is full-time or part-time. Most people are looking only for one or the other, and will not apply if the required work hours do not suit their needs.
The most important part is the body of the post. Tell the readers in detail exactly what the job opening duties are. This gives the applicants a good idea ahead of time what you will expect from the person you hire. Also include any education requirements, as well as any desired experience. If there are certain physical requirements, such as standing or sitting all day, make sure you include that information. Do not sugarcoat your description, as this will only get a lot of applications from people who can't or don't want to do the job that needs to be done. Be as specific as possible.
Now the potential applicant has a good idea of what the job will entail. Now is the time to start giving additional information. Applicants are also very interested in the compensation available. You do not have to be specific, but it is important to post a general pay scale, and to let potential applicants know whether the company offers any benefits. Finally, you need to give specific instructions on how to apply for the job opening. Leave a phone or fax number with a contact name if that is what you prefer. If you are listing an e-mail address, make sure you have the applicant type in certain words in the subject line so you will know that this email pertains to the job opening. If you wish to have the applicant come in person to your place of business, make sure you have posted the company name, address, and phone number so your applicants can find you. It's also a good idea to have predetermined times during which you will accept applicants. This ensures that people are not coming in during peak times of the day.
Remember to be honest and detailed regarding the job opening to avoid an overabundance of applicants that will not fit the job opening you have available.
