Is there any way to check page position in Google serach (I don't mean browsing, just in one request ). There seems to be a problem with Google SOAP Search API for a long time as I know.
You can always try with functional testing tools. Like selenium or canoo web test.
What you have to do is to loop throw pages (add keywords in google search input box and then simulate clicks on the links to next pages in google search).
And on every page you just have to check if your page title, description or link is on the page.
Only problem is that you can check (its google's limit) only 100 pages (1000 results overall for keyword(s))
