Nodes in keywordspace don’t die with the businesses that created them. The popularity of domains and links and words and phrases are permanently altered by the existence of the business. It’s a digital footprint like how a real-world business leaves a physical footprint. Some footprints are harmless - just a memory of activity that once happened. Other footprints cause lasting harm, like contaminated soil. Abandoned formerly-popular domains create a kind of long-tail info-environmental impact, just like an abandoned warehouse can become a real-world hazard. Maybe we need a digital superfund process.
