Google removes page from index after a day or two

[andhradude]

Hi,
Issue 1:
Google indexes a page in my website and I can see that via cache and also users will come thru google search result. After a day or 2 it removes that page from index.
Here are my observations.
As long as it stays in the home page ( as latest ) it indexes. Once it moves to inside page it removes from indexing. But still the page is accessible via header tab ( call it Picture Gallery ).
I tried google site maps too. That too never helped.

Issue 2:
Google indexes index page of a section ( call it articles ) i.e available in header tab. But never indexes the links that are present in that section.

I tried Google Site Maps, and also mod rewrite function to convert article.php?catid=12 to /why_this_page_is_not_indexed_12.html
But no use. those pages never got indexed.

Please help!

Thanks in advance.

How long has this site been up?

I find their filters take time to hit the pages, often times it depends on where in the month the rankings appeared.

This is site is up for 2 years. It is having PR 4.

Our site is only four months old, but similar.

new pages will be added then dropped, but get aded again when crawled again.

Basically when the freshbot finds a page for the first, that only keeps it in the index a day or two.

Not much to worry about in this, other than you will need to keep new pages linked from a main page longer to get them truly indexed sooner.
