On every sales page, the google cache button links to:
cachehttp://
It should ofc be:
cache:http://
:) typo
Even better would be to link to:
site:http://
Because cache doenst really mean much, except things being buffered by google, and yes they are also indexed.
site:http:// are all the actual indexed pages, cached or not does not matter.
Indexed means it will be found by searching google, so cached pages will ofc also be found, but you will miss out on a lot of indexed links from a sales point of view, because it takes longer to get cached, but eventually most indexed pages will be cached (up to some point)
