So, what's the deal with the term 'SEO Blog'? Tad Chef (writing for SEOptimise.com) seems to think that topic-relevant links to other websites are a great way to rank for those topics. Now, I could be cynical and suggest that his article Linking Out Instead of Link Building to Rank in Google is just an attempt to encourage more people to link to SEOptimise.com... but I actually happen to agree with it. For me the key part of the article is that outbound links encourage owners of those links to 'return the favour' by way of a mention in a blog or a tweet.
Links out to relevant sites and pages are a "good thing" for everyone, so I'd encourage them in principle. But just in case they have any direct influence on rankings, I'll add another link to SEO Blog! I hope you enjoy the read, but come back here soon :)
