Seems like my blog has disappeared from google again! Since this happened the first time (see here) I regularly check to see if my pages appear in google by doing a search for “site:luckhurst.wordpress.com”. Yesterday this returned all my posts but today it’s down to 3 pages. This would explain why I’m getting no search hits showing up in my blog stats 
Last time I though it was because the privacy option on my blog had got changed but I have checked this and it is still set to the correct value. Hopefully if I keep posting this will sort itself out but it’s a bit disappointing as I was getting a regular (albeit low) number of hits a day.
Update: 2 days later and we’re back in business! Google search has all my pages back again – weird.
When I first moved to WP, it took Google a long time to index me. All OK now. Maybe this was just a temporary glitch.
It’s happened a couple of times now and it does only appear to be temporary. Both times it’s back to normal after a couple of days.
