Google's new algorithm: more spam prevention

Posted by David Khoirul

Google's algorithm and spam protectionGoogle is more sensitive to spam now. The search engine giant has launched new spam detection and prevention, which may impact in certain websites or blogs from ranking well in Google. No wonder I see slight changes today in my blog traffic.

Comparing to previous days, today's traffic on, and on some of my bahasa Indonesia blogs, drops from 20% to 60%, which may be caused by all the broken links here being considered as spam. In fact, those links are the results of blog migration last year, from WordPress to Blogger.

Matt Cutts, the guy behind Google's complicated algorithms, has confirmed this in a blog post at his personal weblog:

That change was approved at our weekly quality launch meeting last Thursday and launched earlier this week.

This was a pretty targeted launch: slightly over 2% of queries change in some way, but less than half a percent of search results change enough that someone might really notice. The net effect is that searchers are more likely to see the sites that wrote the original content rather than a site that scraped or copied the original site's content.
