I have an ecommerce site that is over a year old. I just checked www.your cache.com and went from being fully indexed to -1 again on all data centers. Usually this happens every few months. I was just reindexed a few days ago, 2 days later -1 again! Not the best time of year to be in this position. Any ideas? girlstuff
Google shuffles its feet sometimes when its indexing sometimes. I'd suggest getting more links to your site, preferrably one-way type links (no reciprocal). You'll get indexed in no-time.
Do you have any server problems? Is your site always up? Is the content unique? Would be easier to give a better answer if you posted the site.
