So, I'm an 'avid' user of google webmaster tools and analytics. I'm building an e-commerce site, all with original product descriptions and a base of 'useful' industry-relevant content. I generated and submitted a new sitemap yesterday with some new content. Next to the sitemap in google webmaster tools, yesterday I had approx '600 urls in web index'. Today... 5. 5!?
There is no canocial issue, the site is configured properly to go to the non-www version, there are no 'spammy' links (probably no links at all at this stage...) and no duplicate or spammy content.
What has happened? To add further confusion, doing a site: search on google churns out 5.8k results, so it's still 'in the index', and monitoring certain keywords tells me that most of them still rank and rankings havent been changed... what is webmaster tools telling me by saying there are 5 urls in the web index?
