The problem with perfect is that it never happens(period). There is always room for updates, maintenance, and improvement. Think of your web presence as a machine that has to be maintained. That is what it is. You can add parts to your machine. We can add forms for your clients to populate their data. We can add analytics to find what works and what doesn’t. We can add SEO to improve advertisement placement. Your machine is what you make it and can be as powerful as you want.
And, it can always be improved.
