WordPress SEO by Yoast
Improve your WordPress SEO: Write better content and have a fully optimized WordPress site using Yoast’s WordPress SEO plugin.
WordPress out of the box is already technically quite a good platform for SEO, this was true when I wrote my original WordPress SEO article in 2008 (and updated every few months) and it’s still true today, but that doesn’t mean you can’t improve it further! This plugin is written from the ground up by Joost de Valk and his team at Yoast to improve your site’s SEO on all needed aspects. While this WordPress SEO plugin goes the extra mile to take care of all the technical optimization, more on that below, it first and foremost helps you write better content. WordPress SEO forces you to choose a focus keyword when you’re writing your articles, and then makes sure you use that focus keyword everywhere.
