Ah, lala. I wonder if these days, the optimization of SEO is really needed, or rather, really useful. After all, these days, thee focus gets more and more about content and smart utilization of a webpage space than any real search engine special optimization. Sure, you may give emphasis to some keywords, but it is also to be found more easily by users. So, it is directly for search engines? Also, the focus is more on quality of the content, than the backlink. Once again, backlinks helps, but if you try to game too much the system, you will be more left aside than anything. Basically, you have to do subtle things to win and get highers in the SERP. What I want to communicate is, I feel like that now, SEO persons are more doing a mix of a web developer and of a PR person than anything directly related to the search engine itself. They will advice you to make a clearer and better structured website, to give clearer headlines, sometimes shorter headlines, and then to talk better to what people care about.
