Anyone know why they would do this? My site has been up for 9 months and ranked well for many many keywords due to quality content. We moved my site to another server and know it seems I only have 4 pages indexed in yahoo? Why would this happen and how can i get it back to how it was before?
How long was your site down for. If it was down for a while maybe some bots visited your pages and got no reply. Probably not the answer but all i could think of. If it is the case just wait and you will be reindexed and re ranked in due time.
