The five best WordPress plugins for a new website

It's no secret that WordPress is a marketer's best friend. This simple, free little piece of software can do just about anything from building the foundation of a blog to providing a way to make sales directly to your readers. I love it. But WordPress by itself is not necessarily a “complete” software tool. You'll need to make a few tweaks and upgrades if you really want to make something solid out of it.

  1. All in One SEO – This should be number one when building a new WordPress website. It allows you to quickly and easily create titles, descriptions, and keywords for your post, index all your categories and tags, and generate keyword-rich URLs. In short, it ensures that your content gets seen on Google.
  1. XML Sitemap - Google likes to see sitemaps on websites with more than two or three pages of content. For a blog, a manual sitemap would take a long time and probably be inaccurate most of the time. XML Sitemap Creator generates a new sitemap every time you write a post and submit it not only to Google but also to the other major search engines.
  1. Ultimate Analytics - Google Analytics is the most powerful free online tracking tool. If you want to know where your visitors are coming from, what they're looking at, and how long they stay on your site, you need an Analytics account. This plugin places the tracking ID for your account on every page of your blog, so you'll continue to get the data you need no matter how big your site grows.
  1. WP Ecommerce – If you are planning to sell something on your website, you can easily add a shopping cart that integrates with PayPal or Google Checkout with this free plugin. You can sell items directly from your website with a redirect to the payment processor of your choice. It doesn't get much easier than that.
  1. AddtoAny/TweetMeme – AddtoAny is a tool that allows users to use a social bookmarking service like Facebook, Digg or StumbleUpon to share your posts. TweetMeme is a "retweet" button that allows instant retweeting with shortened URLs. I recommend you add both to your WordPress to maximize your content sharing.

Simply put – you must be willing to play with some of the features and toolsets available for WordPress. The possibilities are nearly endless when you do this, and it's fun to see what you can accomplish with simple, free software.
