SearcheEngineLand posted about it here. You can read it straight from Google's Webmaster Central Blog here. Google says they are after keyword stuffing and link schemes. As examples of the type of content that will be effected they posted a screenshot of an article with hundreds of tags added to it as keyword bait. They also posted up a screenshot of a spun article with irrelevant backlinks implanted in it. From the sounds of it, it looks like this is going to heavily impact the majority of link building services that surround the forums. Is spun content going to be whipped out or just irrelevant content surrounding your links. What's your thoughts?
