Aha! My little experiment in practical search engine content discovery is accomplished. Namely, I put a page up about something very obscure on the 20th June, and waited until search engines found it.
Google, for example, has only just stumbled upon it – apparently when I updated some other pages yesterday, it rummaged around my site (good to know it’s in the ‘check for changes daily’ category!) and discovered it then. (Note how it doesn’t have the ‘cached’ date for the page like it does for the Misc page that links to it.) Perhaps it’s due to how it sees the ‘freshness’ of my site?
