As well as looking good, your website is there to do a job, so it needs to be kept in good working order. Electronic items such as mobile phones receive automatic updates to improve functionality, fix glitches, get rid of bugs and protect against viruses, however websites work differently and need constant support and maintenance.
Hosting companies, WordPress and other plugin providers issue regular updates to their product functionality and features to ensure that the product evolves. Your website needs to be looked after and monitored to avoid becoming vulnerable and a potential target for hackers and scammers. All your hard work could be lost, and this can cost your business in many different ways.
