Thanks for your help Adam although i am confused by 'we do not move a
site's pages from our main to our supplemental index in response to any
violations of our Webmaster Guidelines'.
Sorry if i have missed the obvious but why do you move it to the
supplemental index?
Your guidelines suggest it may be because the URL has too many
parameters to crawl however if its impossible to crawl how did it end
up in the supplemental list (it must have been crawled.)
Do you mean quality backlinks to the site generally or to the specific
page that was supplemented? If its the later then how do i get a
quality backlink to a page on say 'privacy policy' or any other unique
-to-the-site topic.
'see a fresher supplemental index in the coming quarters.'
does this mean even more pages will be supplemented?
Is there any chance you could introduce a user friendly search facilty
for the supplemental indexes as most of our customers would never think
of using a 'site' command .
