Here’s a start:
Security
Is the name of the game… Monitoring security and ensuring full recovery is quite a monumental task. It’s also very vital. You’re at war with an unforeseen force that stops at no end to steal sensitive data that may be contained within your site, or insert malicious scripts and code that can be used as spam and get your site pulled offline. So, you either need an employee who understands and knows how to proactively combat these breaches, or you need someone to do it for you. Hiring a professional ensures your own peace-of-mind in knowing your site is being kept safe, and, if anything were to happen you’ll have the right resource to step in and provide the solution you need to make sure things remain uncompromised and operation continues on smoothly.
Updates
Any CMS platform you’re on will introduce major updates a couple of times a year, while minor updates roll out as needed (and are generally pretty frequent). While these updates will be available to you, it’s up to your team to actually implement them. There are also updates for themes and plugins, which are much less predictable. Many of these plugins have vital security updates that have optimized their codebase to speed up your site and more succinctly secure your CMS. The longer you wait to initiate these updates, the more “out-of-date” your plugins become, leading to issues, if not immediately, surely down the road… In short, you’re not monitoring the existence of these updates, they’ll never happen. And that’s just not smart.
Backups
Hey, you’re site just went down. Or, hey, your intern just crashed the whole site while navigating the backend code of the site. What’s your plan? Don’t have one? Whoops. Your site should have a backup plan in place, because, it will inevitably need to be accessed and acted upon at some point. A site with lots of content updates might want a database backup once a day (at minimum) and a full backup weekly. Sites with fewer updates might not need backups as frequently, but should still have regularly scheduled, full-site backup that is stored off-site in the event of a catastrophic experience.
Tracking and reporting
Generating a stats report isn’t very difficult. But it can be a whole mess of gibberish and endless analytical bits of nothing if you don’t know how to harness the power of “what’s inside,” and put it to use. This information provides answers to what’s working and what isn’t with regard to the operative functionality of your website. If you’re not making things easier and more engaging, you’re going to lose your audience. And if (and when) that happens, you lose.
Maintain. Improve. Engage. Repeat.
