One of my pages suddenly disappeared from Google search results

I wish to know; other than writing directly to Google, is there any way that a page that suddenly dissapeared from Google can be reindexed?

It is strange, just a page dissapeared.

This kind of thing happens pretty often. It can be:

1. not enough real PR for Google to keep that page in their main index
2. a duplicate content situation that causes your URL to be filtered out on that search
3. a penalty that pushed your page down into the deeper regions of the search results
4. a bug at Google, in which case the page usually re-appears in a few days

I hope so, I was modifying the page daily to make efforts to improve my content, bounce rating, etc., and suddenly, from spot 5 I totally dissapeared... I cannot even find it with "domain name + keyword". Strangely, another page (unrelated) appeared on page 5...

I asked on Google Webmaster tools for the page to be reincluded... but the form askes for the main domain name, hope they don't mix things up.

Not saying that your page shouldn't be important to you, but I think that sending reinclusion requests for every glitch you see in Google is going to make it impossible for Google to provide any sort of meaningful support at all. If I had a page disappear, I'd give it some time and I'd investigate possible causes myself. And I'd give it some more time.

Daily? Possibly also you overdid it with page changes. Google doesn't like it when you change a page too much. Possibly Google can't even sort out all your changes. Re page changes, think about them a lot before you change anything. And again, give them some time to settle once you've made a change.
