At the beginning of this month, we had reported that, Google had blocked the widely used search engine rank checking tool 'WebPosition Gold'. Then, a few days later Matt Cutts and Googler JohnMu spoke about the reasons and the methods that Google employs to block such automated rank checking tools.

Now, according to Search Engine Roundtable, it seems that Google is hell bent on its resolution to evade and block scrapers, by deliberately changing the search results in an effort to confuse the scrapers.

According to Search Engine Roundtable, “It seems like Google may have implemented a feature that is transparent to searchers but can totally mess up rank checking tools. This is not just impacted WebPosition Gold, but all scraper based tools, including the SEO Firefox plug-in.”
