We submit a sitemap to google and can see this being indexed in webmaster tools. We have 5140 entries, and have broken this up to 10 child site maps of 500 each. This all seems to be working well.
Google, however is not indexing all entries of three of the child site maps (all others seem to be nicely indexed). The number of entries indexed has remained static for the last 6 weeks.
We would now like to determine which url's are not being indexed by google, to try and see if there is a content issue or otherwise.
Is there any way to determine which url's are not being added to the index other than manually go through all 500 entries using 'site' on google?
