I have a recently built website, very clean, no tricks used and built very strictly within Google's webmaster guidelines. I submitted it to google sitemaps for which there are no reported errors. The googlebot visits every two or three days and crawls every page. Using the site:mydomain.com operator since it was published I have seen varying amounts of results returned from around 100 and sometimes just the homepage.
That was until yesterday when I saw that ALL pages are now in the supplemental index! Has anyone an idea what might be going on?
And of course in all other search engines the site is indexed correctly and ranking reasonably well
Actually your thread title and your post are contradictory. You are saying in your post some of were pages were in the normal index to begin with and then went supplemental.
What your title says is what I've seen. I had a one page site (with the words 'coming soon' on for a few years (never got around to developing the content). I finally decided I would just put a blog on there since it was a PR4 (yes it had a couple of accidental links from other peoples sites). I put a lot of posts on in the first month and all of these new posts started as supplemental Last year the index didn't behave like this in that they would have started in the index and gone supplemental if the links disappeared.
I don't know what it means (and there are one ot two other explanations) but I thought it significant in terms of the new beaviour of the Supplemental Index.
