These simple steps could help your site a lot. As with most SEO I can't prove it was 100% these changes that got the results however I haven't done any backlink building for ages (I have been promoting the site and focusing on traffic instead) and there are no other reasons I can think of for such a huge SERP boosting.
Just thought I would share these tips as the warrior forum has helped me a lot. I hope I can help some people too.
