First of all website is the key for your business image, so paying attention to it, could win customers.
I'll point out 4 reasons why you should update your website.
MOBILE FRIENDLY
I bet you can't count people on your fingers who don't have smartphone. THIS makes a huge difference whether you can enter a website with smartphone or not. About 50% of internet traffic moves in smartphones. So take some time to seed this point.
SEO - search engine optimization
I hope you all know what this means...you type something to google and hope to find it on first page, i bet 80% of users even doesn't go to second page. SO let your webpage be optimized to be found always on first page. This means you should have quality content also.
Webpage SPEED
Who wants to wait 5-10 seconds while a page is opening? Me neither.
USERFRIENDLY
Make your website userfriendly. Don't hide buttons, dont make text too big or too small. Think like you are a visitor and how it should be to orientate there. If you have atlest one question about something you can find at webpage, your page is not userfriendly
