SERP accuracy

[LBCsm]

I'm tracking SERP's from a proprietary AutoIT script (for those interested, see AU3 code below).

Results aren't spot on though. For instance, one of my sites are ranking #9 (as what I see when I visit google.com/ncr myself and is shown by SERP tools like Firefox plugin Rank Checker etc.), however the AU3 code gives a #7 result.

What methods can be used to get more accurate SERP rankings? I tried different user-agent's however this doesn't seem to make a difference. I'm not necessarily looking for replies based on the code, but more in general what methods can be used to get more accurate SERP's.

Thanks!

$url = "http://www.google.com/search?q=" & $parsedkeyword & "&hl=en&start=" & $index

Local $oHTTP = ObjCreate("winhttp.winhttprequest.5.1")
If @error Then Return -1

$oHTTP.Open("GET", $url)
If @error Then Return -1

$oHTTP.SetRequestHeader("User-Agent", "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10 (.NET CLR 4.0.20506)")

$oHTTP.Send()
If @error Then Return -1

$oReceived = $oHTTP.ResponseText
If @error Then Return -1

StringRegExp($oReceived, '<a href="([^"]+)" class=l[^<>]*>.*?</a>', 3)

Hmm, try to use a proxy to view your ranks, google.com/ncr isn't accurate.

Thanks. You mean a US (or which country has to be queried) based proxy to be able to query google.com instead of querying from abroad appending /ncr?
