Description
CyberSEO Lite is a simplified version of CyberSEO Pro – the most advanced but easy-to-use auto-blogging and content curation plugin for WordPress. CyberSEO Lite is intended to import RSS and Atom feeds and automatically convert the content into WordPress posts at your site. The plugin is equipped with unique and very powerful software tools that you may find in premium solutions only.
At the current moment, CyberSEO Lite is the only open-source freeware plugin which is able to extract full text articles from shortened feeds, translate the articles from/to over 100 languages with Google Translate and Yandex Translate services, spin it with 3rd-party content spinners* and more. All these features are 100% free and available right after activation of the plugin. No catches, no hidden fees, no limitations!
* Important notice regarding 3rd-party content spinners
In accordance with the WordPress policy, the content spinning scripts can not be hosted at www.remarpro.com. Thus you have to manually download the spinners.zip archive from this page, unpack it and upload the contained spinners.php file into the /wp-content/plugins/cybersyn folder of your site.
Don’t worry, it’s a freeware GPL script, so it’s not a premium (paid) module. Just download it, unpack and upload it into the same folder at your site where cybersyn.php is located, and the content spinning feature will become instantly available.
