There are a few practices with websites that I would call "website management 101." This applies to any business, small or large, that has a website - which means, it applies to just about everyone!
1) Update your content.
Photos, blogs, and social media need updates ranging from daily to seasonally, depending upon the channel. You don't want these critical assets to appear stale or seem outdated.
I like to do this seasonally with website management for my clients as both outdoor and indoor photos often naturally reflect seasonal changes. You don't want to have a snowy photo in the middle of summer. It causes a disconnect, and the user may wonder if you've done any work in the last 6 months.
2) Think about the most important points you want to convey to your customer.
Once you've decided on these points, take them and make sure this aligns with the first impression for your website visitors. First impressions are everything with websites and influence how a user feels about your business - there's lots of data out there to back this up.
Depending upon your industry, you can convey the points you want to convey to the user. You can do this by showcasing your best work in the first photo, posting testimonials on your homepage, and highlighting your recent work.
Testimonials are also something to keep updated as your client list and business expands. They're great to have on hand for your website, social media, flyers, and more.
3) Use your site.
Test your website out to see how it's functioning and ask yourself - are pages all working, do images look crisp, is all written content free of typos.
Do this on both desktop and mobile. You might think a website looks amazing on a desktop computer but notice that it's in complete disarray on a mobile device. No matter what device your visitor is using, it's important to provide an easy-to-navigate website and user experience through consistent and detail-oriented website management.
