1. WP SpamFree
WP SpamFree allows you to eliminate automated spam bots from controlling your comments, by using javascript and cookies that stops the bots from processing the automated spam. This virtually eliminates the need to type out annoying CAPTCHAS for your commenters. However, nothing is as full proof as the CAPTCHA method, as annoying as it may be. Thus, I’ve also recommended the WP-reCAPTCHA plugin as an alternative.2. Ultimate Google Analytics
Ultimate Google Analytics allows you to automatically sync your Google Analytics account with your website. This plugin helps you manage your visits, page views-by date and location; and track links. This is very helpful in understanding and analyzing who frequents your site, where they came from, where they linked to from your site. Very useful if you are managing a blog with ads, in which advertisers are paying per page view, etc. Which leads me to my next essential plugin:3. All in One Adsense and YPN

Publisher Network account, as well, doubling your advertising options. It will automatically create the ad codes in your posts, once you provide the publisher/channel IDs. Everyone enjoys the benefits of the lucrative advertising empire (except those unfortunate internet perusers unaware of Firefox’s Adblock add-on).
