Site forces quality changes for submitted articles.
One of the sites frequently mentioned as being targeted in Google’s recent quality crackdown is EzineArticles.com.
It should come as no surprise that today the site instituted new rules and checks for quality.
The site lets people submit articles that are free to reprint. The author gets a number of benefits, but backlinks are one of the biggest. As a result, many authors submit quick articles with little substance solely to get the backlink.
The new quality guidelines include increased quality checks, no article submission through the API and Wordpress Plugin (which was probably being abused), and a new 400 word count minimum (because longer garbage is better than short garbage.)
Will Google accept after-the-fact changes to site quality? My guess is it takes a while to change a reputation.
