Not responsive and mobile friendly
If we told you that primary usage from midnight until 9:00 twas mobile from 9:00 to 17:00 it was desktop and from 17:00 to midnight it was tablet would you be surprised? Your website NEEDS to be able to render on all types of devices and all sizes.
Hard for people to contact you
Contact info should be on every page - you want them to reach you, make sure it's easy to do. We mean REALLY easy.
Slow loading images
You have on average 8 seconds before people leave, make sure you use your time wisely - looking at a blank screen is not going to work.
Too little fresh content
Did you tell Google you exist?
The whole reason you have a website is to be found - yet so many of my clients come to us without having done these steps.
