Organize your permalinks. You need to make your links easy for the search engines to find your important information. You should learn proper SEO to do this. In the meantime, you can use WordPress's included permalink form to clean up links before publication. Cut words down to only the most important ones. Also, try cleverly adding your keywords to your descriptions.
It's important that you are the only one with your WordPress password. Also, only use plugins from sites of good repute. If your site becomes compromised, you will have to begin again; therefore, it is important to do everything you can to keep your site secure.
