Job boards have evolved considerably over the years both in facilities for job seekers but also for recruiters. CV searches are now a common way for recruiters to find suitable applicants for a vacancy. They'll log on to a site and list the job title, key words and criteria (such as location). The job board engine will then analyse all the vacancies on the site and create a shortlist based on − you guessed it − relevance against the key words. So, if you want your CV to appear at the top of the search then you know what to do.
Don't confuse key words with jargon. Most industries and roles have their own jargon words and acronyms. It's sometimes tempting to put them in your CV to show that you know what you're talking about. Don't be tempted. Don't assume that words used in your organisation will be understood in another or indeed by an HR professional who may look at your CV first. Using lots of jargon in a CV shows a lack of communication skills and the inability to speak to different audiences. Jargon is not the same as key words which are generic terms and can be used across the recruitment landscape.
Keywords are therefore a vital component of your CV. And as technology moves onwards and upwards it's important to play technology at it's own game, and give your CV the best opportunity to be top of the pile.
