All the pages from this one site I have are indexed. In looking at my logs, I see that for some short period of time each day or two, the pages on this site are included/ranked well in the SERPS (I see the queries). But then I browse to that URL from the query (from the log) and my site is nowhere to be found. This has been happening over and over. So it seems the pages are spidered, then ranked, then filtered out after a short time...this process repeats...
I'd be happy if these pages would just stay in the SERPs instead of teasing me like this.
Anyone experiencing the same? What does it mean?
