Google unveiled an algorithm update last week (called the "Farmer update" for reasons to be explained below) which has caused wide-spread panic among websites and webmasters.
The impact, according to Google, affects 12% of all search results in the United States.
Here's the scoop:
In an ongoing effort to make sure SERPs aren't dominated by low-quality content farms, Google rolled out its latest update to scrub search results.
This from the Google blog:
"But in the last day or so we launched a pretty big algorithmic improvement to our ranking—a change that noticeably impacts 11.8% of our queries—and we wanted to let people know what’s going on. This update is designed to reduce rankings for low-quality sites—sites which are low-value add for users, copy content from other websites or sites that are just not very useful. At the same time, it will provide better rankings for high-quality sites—sites with original content and information such as research, in-depth reports, thoughtful analysis and so on."
Notice the phrase "sites which are low-value add for our users" and "copy content from other websites or sites that are just not very useful."
There are a ton of websites that copy content from other websites. Some of these websites are referred to as "scrapper" websites because the "scrape" (or copy) content from other websites.
As noted by Econsultancy, eHow, Associated Content (purchased by Yahoo), Business.com, Mahalo, ezinearticles.com, hubpages.com, buzzle.com, articlesbase.com and others, are taking a hit by this update.
In addition, some SEOs are seeing drops in websites that are competitors to Google Maps/Places because they offer maps or business listings.
Will this hurt your website? Keep an eye on your traffic; pay attention to your Google Analytics report and watch your overall keyword rankings.
In addition, website owners should continue to build quality inbound links and write good, quality content for their website. Make sure your Google Maps listing is completed and up-to-date.
More to come, I am sure.
