Being an early user of computers (1973) and having coded my first website in 1998, I’m regularly asked how often a website “should” be updated.To keep up with current trends or near-current trends, it’s important to write “update website” on your marketing plan every year. That doesn’t mean you spend $5K to update it! Instead, look at polishing the text a bit every year and tweak or revamp the look every two years.
Sometimes, updates are small. In 2001, I removed music from my home page that was popular in 1999 but had become annoying. In 2003, I added a logo created by a pro and removed pop-ups. I also updated all my marketing collateral (printed materials) to match my website.
Mid-size changes might look like adjusting the dimensions of a website to reach across the entire screen, creating a border around the pages, or updating the font.
