Evening all!
I've got an established site (+15 years) that's been doing well (touch wood) in the SERPs for a while now.
On part of my site, I have a section where I post advice and articles where I try and add a new post every month. However, the past few weeks, I noticed a problem and cannot work out why it's happening.
Basically, I add a new page and within 1 day, I see it indexed on Google. However, a day later, it's gone. Searching for the page manually doesn't bring anything up, either. I'm not blocking it with robots.txt or anything and I cannot find any reason for this to be happening. There're also no messages on GWT. Is it just an anomaly and maybe the pages will come back at some point or could there be a more serious issue here?
