I have read through most online articles about tweaking Wordpress for SEO, and done most of the things they suggest such as disabling duplicate content, changing perma-links, adding meta tags, writing detailed and keyword rich titles and descriptions, but wanted to make sure this was all the best way to go. I am ranked number one on several of my keywords, but would like to try and rank for others as well. I have read a lot on this site, and I'm under the impression that the more pages you have indexed in google, the better. Should I have my duplicate content (author, date, category archives) enabled to make my site bigger, or will the duplicate content hurt more than help?
