WordPress SEO is a new plugin by Joost de Valk that finally makes search engine optimization in WordPress seem like a built in feature. I used All-in-One SEO pack for a long time, but was never 100% satisfied with the plugin, especially the interface.
Joost’s plugin not only features a great interface, it actually handles the functions I was using three plugins to do before. WordPress SEO features XML sitemap building that works better than the standalone plugin I was previously using, and it also enables you to add content to your RSS feeds.
The plugin has very detailed options that allow you to control every aspect of your site’s SEO. You can set defaults for page titles and meta descriptions, choose what you want to limit from the search engines with a comprehensive indexation page, and even add SEO-friendly breadcrumbs.
The best part, in my opinion, is the options panel you see on pages and posts (pictured above). There you can override any default content in your title and description, but it even includes a preview of what the URL will look like in Google search results.
The plugin is still in beta, but I’ve already started using this on all my new sites, and I can’t wait to see what kind of updates Joost comes up with in the future.
