It look to be supplemental index update cause noticeing many of supplemental pages for couple of my sites are out of supplemental hell and are in regular index.

Is there anyone here seeing the same?

I'm seeing a regular parade in and out of Supplemental on some sites. Hard to figure what they're playing with -- I posted elsewhere that one of my suspicions is a new measure of how frequently any query actually taps the url at all (recording impressions only, not clicks/CTR).

I still don't even know for sure that I am seeing right measure for pages in supplemental. As noticed elsewhere, site: results are very odd at times, and the same url with the same cache date sometimes shows as Supplemental in the site: query and still without the Supplemental Result tag in the regular search results.

Is it six or twelve months since some major change was made on any of those sites, perhaps?

I can see no change in my supplemental pages.

I wish I understood how Google's criteria for making a page supplemental. All my sites are affected, and in the oldest site (2002) about 1/3 of 400 pages are supplemental, but I can't see any logic to it.

For instance I have a supplemental page about a scenic attraction where the three-word name forms the page title. A search with KEYWORD1 KEYWORD2 KEYWORD3 brings up a relevant Wikipedia page, but this is followed by pages which have no relevance but just include the keywords seperately in the text. But a search using quotes "KEYWORD1 KEYWORD2 KEYWORD3" brings up my supplemental page as number 1. However as the average searcher is unlikely to use quotes, in practice the page will never be found. The name is admittedly rather obscure, but it exists, people search for it, and the page used to bring me traffic before it went supplemental - I just can't see Google's logic.

Roughly since 3 months I started adding new pages, set of internal links added on right nav in each page and a homepage text link.

I'm noticing that more and more of my pages are ending up in the supplemental index. I get spidered very quickly, the page is in the main index for a few days then is relegated to supplemental hell. What is very frustrating is that a lot of the older pages were very popular original content. There seems to be no logic when Google thinks my T&Cs page is more worthy than an original article
