Google shifts its emphasis to quality of content.
According to the article, it goes back to Google’s guide on content creation:
“Content is key. Good content — clear, concise, informative — is better than bad content.
Use plain English. Write for real people.
Keep links to a reasonable number. Make your content readable.”
Lovely extract from the article:
“Really, it all goes back to one idea: Create quality content, and you won’t have to worry about it riding the Google update rollercoaster.”
