I'm starting a blog on wordpress and I wonder what I should do before posting. I want to avoid problems with security, when changing theme, or having to fix something in each entry when I have published 100? I hope you can help me to complete the list: Security: Login Lockdown: limit login attemps Sucuri security: malware removal and website monitoring iTheme security Backup: Manually: Cpanel + Filezilla Automated: using some plugin and saving it in Dropbox Themes: Should I buy a premium theme? free themes can have malicious code, not updated... is it a high risk using wordpress? Any reliable application to analyze themes? Also a stupid question. If I use a free theme in one of my blogs hosted in the same hosting plan and I am hacked, could it affect my other blogs? Initial on-page SEO: Wordpress SEO by Yoast .htaccess redirect from without www to with www tags h1, h2? any plugin? SEO friendly URL: do you think homepage-url/post-name-with-keyword is the best choice? It is simple, and this can avoid duplicate content. I can also make changes in the categories. optimizing images size? Any tip or plugin?
