Expiration Date: Food and Web Content Both Go Bad
Search Engine Optimization - by: Dan Jeffers - 2013
This link goes to a website displaying a week's groceries for families in different parts of the world. Each has a different mix of fresh vegetables, dry foods, and processed food. Great Britain and the United States don't come off too well, we seem to eat a lot of stuff that comes out of packages--probably with expiration dates in the far future. Ideally, the food would look more like this image from Australia:
Lots of fresh fruits and veggies, some meat that is also fresh, with bottles and boxes of stuff in the background.
If This Were Your Website, You'd Want Fresh Content
Well, not everybody wants that. Some content stays good forever--longer than a package of Twinkies. But most people like to see content that's recent and relevant to current conditions. We wouldn't want to see old dusty boxes of food products that aren't even being made anymore.
On the other hand, think about what this collection would look like if we leave it out for a month or so. The veggies would be squishy and rotted, the meat would be covered in maggots. The boxed and bottled foods in the back might still be edible, but nobody would really want them. The smell of the garbage would likely permeate the packaging, and would certainly ruin the experience.
Web Content Needs to be Managed
Posting web content is only one part of the equation. Older content needs to be moved off the front page and into the refrigerator. Really old content will only survive in the freezer. Or discarded. Some content goes bad quickly, some may last for a long time. But if the dated content is on the front page, the whole experience is ruined.
