Hi
The calendar in Roller can cause a small problem for search engine spiders
since its possible to page backwards in dates by the calendar. Its
actually possible to page pack to the year zero...
Ex: http://rollerweblogger.org/page/roller/000104
A spider hitting such a "trap" will just continue to page backwards until it
"gets tired".
There are two dangerous problems with this:
- This can cause unnecessary stress on the server running Roller (ex; Yahoos
spider make big slurps and do actually not consider if the server can handle
it or not).
- At some point the spider will "get tired" because such paging will
generate a lot of similar pages (when there are no content all pages will be
similar) and the spider will then mark the site as "possible spam" due to
all the similar pages.
I would like to suggest that there might be added a small check which makes
the backward paging in the calendar only go back to when the first post was
made in the blog. This would cause the calendar to page back to the month
when the first post was added to the blog. To be able to page beyond that
month does not have any actual interest.
Kind regards
Trygve Lie
