Good Page Titles, Descriptions, and Keyword Tags are all good things to pay attention to. Use All-in-one SEO and you can fine-tune your posts. Google likes websites to have a privacy policy and a site map. It's always good to have a privacy policy these days and the site map makes it easier for search engine crawlers to find every category in your blog. Other than that, if you have a stale blog, meaning it is not updated with quality, relevant content at least weekly, that would hinder your page rank. So post at least weekly with something meaningful with at least 300-500 words and use the All in one SEO to make sure the post title, description, and keywords are relevant to the post.
