Websites come and go, many end up neglected or personal circumstances force a sale as the owner looks to cash out. Buying and selling of websites has become more common over time... but what if I don't want the entire site? Most sites are bought with an idea or goal in mind, many are dismantled and have their traffic redirected etc...
How viable would it be to sell a website on a page by page basis?
Technology exists to redirect a visitor and tell the search engines a page has moved so why has nobody jumped on the buying and selling of individual already published and established web pages?
The value of links can be passed on with proper redirects and the redirect can be included in the terms of a sale. SEO and link structure can be improved upon on the new site as older sites often have many issues... so why has this type of selling not flourished yet? What obstacles would be faced? It would possibly cut down on the number of pages being produced and would ensure the best of the best never just vanish into oblivion.
