Been using an xml sitemap on a new site (6 months) for about 2-3 months now, the site had 55000 pages and 44000 indexed prior to submiting a sitemap. Admitedly there were some pages indexed that I did not want indexed and are now not indexed.

Here is my head scratcher.

Since submiting the site map I noticed a gradual reduction of indexed pages using the site:www.d o m a i n.co.uk search from 44k down to 22k over a 2 month period. This has now bottomed out and is now on the climb so I am not to conserned as I know there were pages indexed that I were not supposed to be.

However the Sitemap statistics in the Google webmaster tools is suggesting I have 42999 pages indexed when infact the site:www.d o m a i n.co.uk search is showing 24,100.??

PS the site has just had an increase of 80k products in the last 2 days, hence the 125126 pages now in the site map.
