On Twitter, Google’s Matt Cutts announced that Google penalized another guest blog post network:
Today we took action on a large guest blog network. A reminder about the spam risks of guest blogging: //t.co/rc9O82fjfn— Matt Cutts (@mattcutts) March 19, 2014
He also said that users of the network will be penalized:
@n2tech when we take action on a spammy link network, it can include blogs hosting guest posts, sites benefiting from the links, etc.— Matt Cutts (@mattcutts) March 20, 2014
Although the tweet did not name the network, it seems that it was MyBlogGuest.com. The website does not rank for its own brand name, which is usually a sure sign that a website has been penalized.
If you use guest blogs to advertise your website, make sure that the links in your blog posts use the nofollow tag. If you publish guest blog posts on related websites that can send visitors to your site, you can continue to do so. Just make sure that you do not use guest blog posts just to get links.
