Google and Freshness

We want to update our pages continually.

hi guys

since we want to feed Sitemaps with our 10.000 pages site in 14 languages, an since not all pages are updated frequently, we want do develop a system in order to update pages "artificially" every week.

We are wondering which factor would have more importance:

-page date
-page size
-change in styles
-...?

SOme questions:
-Would google consider a page "fresher" if we change the text in the header one week to bold, the week after to italic, and so on?
-If we change i.e. one picture in every page every week?
-if wee add some code in the page so the size of the page increases in Kb from one week to another and then again we reduce it?

What else do you suggest?
It is a normal html static site.
We use DW and Contribute.
It has to be an automated solution.

Cheers

First thing to do that is extremely easy is to insert a date function from your programming language.

Even if you have a long date format, the size of the file will change slightly (may vs februrary).

I'm not sure how important file size is.

You could even do something like randomize a comment.
"today is 15th"
"welcome, today is the 15th"
"You are viewing [page] on the 12th"
