Set the “Show Excerpts to Non-Members?” advanced option to allow a search engine/search bot to crawl and index your private content so that your site can still rank for keyword searches — allowing you to attract new members or preserve search engine traffic for an existing website or blog.
WordPress is, out-of-the-box, one of the most search-friendly platforms you can use as the basis for your website. The PMPro plugin functions within the confines of WordPress and therefore inherits all of the built-in SEO benefits. You can enhance your site’s SEO using additional WordPress plugins, such as the All in One SEO Pack. These additional WordPress plugins will function seamlessly with PMPro — no technical skills or advanced integration required!
