The best way to maintain your website’s performance is to constantly update it. Knowing which parts of your website need to be updated to maintain performance and planning for those eventualities will help you avoid massive website overhauls in the future.
As you spend time evaluating predictive analytics tools and judging which CRM has the most to offer in the way of supporting your business objectives, make sure you’re devoting just as much time and attention to the central component of your online strategy, the platform that your website is built on.
It's possible that if your website is dealing with frequent security breaches and UX issues, its showing symptoms of no longer being supported. This is how you catch an unsupported CMS, and save your website with a migration.
When deciding on the right CMS platform, ensuring that you choose the right platform depends more on how customized you need your website to be, and less on the set of features your platform should have.
