In a blog post today on Google’s official blog, the search giant is announcing some major algorithm changes to its search engine that is perhaps the most unnoticeable change, but one that is going to improve the quality of search results from Google.

Google is targeting content farms, low quality websites whose main goal is to rank well in search traffic with useless content that is usually copied from websites with the original content.

In the blog post Google did not outline the exact changes but they did throw around some numbers, saying that it should only impact 11.8% of search queries in Google. Google’s code changes will only roll out in the U.S. with plans to roll out worldwide over time, but it will affect the ranking of many sites on the web.

“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,” says the two Googlers in the blog post.

The upcoming changes are sure to have many up in arm, complaining that their website is unfairly ranks, but in most cases Google will have a fair rank of the owners website.

It’s no objection that Google’s search engine is the best in the world, but this most popular search ending has been plagued by the SEO practices of content farms, allowing these sites to rank at the top in most common searches. It will be a huge step for Google to put an end to these content farms. It is an important step for making their millions of users feel safe and getting the highest quality web search results that they deserve.
