I am tracking the large WebmasterWorld thread on the topic of WebPosition Gold no longer working on Google's search pages. It seems like WebPosition Gold is releasing an update today, that will address the issue that is preventing the scraping of the Google results, which stops the tool from building Google ranking reports.
WebPosition Gold employee, Scott, said in message number 3726633, yesterday:
I have an update going out today which should improve things for WP users...
That clearly implies that they have reworked the program to properly pick up the Google search result pages and document rankings again.
Member, pageoneresults, feels this fix won't last too long. He feels Google will counter WebPosition Gold's update with a slight change themselves, which may cripple the software from documenting your Google rankings.
Clearly, Google is not happy with people using these tools. But it doesn't seem to be the top concern for Google at this moment.
