The first relates to internal link structure. I’ve made the mistake you say you’ve seen so often. I have a primary keyword and have used that keyword in the main navigation, linked to a page optimized for that keyword. But I’ve also got a bunch of contextual links in posts pointing to that page, usually with the keyword in the anchor text. I now understand that those internal links aren’t helping much, at least from an SEO perspective. Am I better to remove that keyword and direct link from the menu and simply link the page from multiple posts and pages within the site. Or will I get better results leaving it in the main menu and changing the contextual links in the posts to point to a related page with a different keyword?
People want to speak their minds and weigh in on subjects they feel passionately about, so building a community into your site is a great way to start a conversation and increase traffic to your website. Implement a robust commenting system through third-party solutions such as Facebook comments or Disqus, or create a dedicated forum where visitors can ask questions. Don’t forget to manage your community to ensure that minimum standards of decorum are met, however.
