This is a fantastic WordPress plugin that allows you not only to control important aspects of your site's SEO, but also lets you specify how you would like your site to display in search engine listings.
We have used the WordPress SEO by Yoast plugin for many years both personally and professionally and taught hundreds of business owners at our WordPress training seminars, workshops and training guides how to install and use this essential WordPress plugin.
We also feature a comprehensive and detailed step-by-step screenshot tutorial on how to configure and use this plugin in our own WordPress training plugin here at WordPress.org, and have published a preview of this detailed step-by-step tutorial on our blog. See it here: [ link deleted, please do not post links in reviews ].
Over the years, we've explored many excellent plugins for WordPress SEO for various different sites that we have built, but we keep coming back to the WordPress SEO by Yoast plugin.
