That's why it's necessary to always stay abreast of developments in the SEO world, so that you can see these algorithm updates coming or you can determine what to do once they’ve been released. The WordStream blog is a great resource for SEO updates, but we also recommend Search Engine Land and Search Engine Roundtable for news on updates. Glenn Gabe of G-Squared Interactive is also a great resource for analyzing the causes and impact of algorithm updates.
Guest posting: If you are thinking of seriously increasing your organic traffic, then you should guest post. This is a way to get backlinks and Google loves this. It shows how relevant your work is.
