Keep up to date.

The pace of change, especially online, is huge. Whilst you most certainly cannot chase every new thing that comes out, you need to ensure you keep up to speed with developments and ideally keep ahead of the competition. Maybe that means recording a Google Hangout or a simple video or even a podcast. These do not have to be inexpensive and are not hugely time consuming. What they do however, is make you credible and visible and support SEO.
