If you would like to increase the exposure of your blog WordPress Connect 
it the perfect plugin for you. It comes with a unique set of tools through 
which you can reach the largest social networking community on the planet 
that would engage and then share and discuss your content. It will enable 
you to build up a fan base and to connect with a wider and a more relevant 
audience. Now your blog readers with a Facebook account can post comments, 
create discussions and like your posts and pages.
The plugin integrates Facebook Social plugins with WordPress. It provides 
tools to add the Facebook Like Button and Facebook Comments automatically 
to every post and page. Of course, the user has a full control over settings 
such as width, font, color scheme, etc.
WordPress Connect also provides fully customizable WordPress Widgets for the 
following Facebook Social Plugins
<ul>
<li>Activity Widget</li>
<li>Comments Widget</li>
<li>Facepile Widget</li>
<li>Like Box Widget</li>
<li>Like Button Widget</li>
<li>Live Stream Widget</li>
<li>Login Widget</li>
<li>Recommendation Widget</li>
<li>Send Button Widget</li>
</ul>
The widgets can be added to your blog just as easy as any other WordPress 
Widget, i.e. through the widgets page (under Appearance on your Dashboard).
Since 2.0, all WordPress Connect widgets are rendered in the XFBML mode (i.e 
no iframes) to provide full functionality the iframe versions may lack.
A big addition since 2.0 is a simple yet powerful <a href="http://wp-connect.tomasvorobjov.com/api/" title="WordPress Connect API" rel="nofollow ugc">API</a> 
for plugin and theme developers who can now specify default settings for WordPress 
Connect to reflect the needs of their plugin/theme. The API provides an easy 
way to include any widget (such as the Like Button of Comments) anywhere in 
the theme, e.g. to add the Like Button to the header or Comments to the 
footer.
Requirements
<ul>
<li>PHP 5.2.0 or newer</li>
<li>WordPress 3.0 or newer</li>
</ul>

The “original” share buttons automatically transmit data of your visitors to the social network sites as soon as they visit your website. They do not need to click on a share button for this and therefore have no choice, if they want their data to be send. The German computer magazine c’t has developed “Shariff” <code>(ʃɛɹɪf)</code> that follows the General Data Protection Regulation (GDPR – Regulation (EU) 2016/679). This plugin adapts the Shariff concept and provides an easy to use solution for WordPress. We currently support 29 services in 25 languages: Bitcoin, Buffer, Diaspora, Facebook, Flipboard, LinkedIn, mailto, Mastodon, MeWe, Odnoklassniki, Patreon, PayPal, PayPal.me, Pinterest, Pocket, Printer, Reddit, RSS, SMS, Stumbleupon, Telegram, Threema, Tumblr, Twitter, VK, Wallabag, Weibo, WhatsApp, Xing.
For more information about the Shariff project check out the original <a href="https://github.com/heiseonline/shariff" rel="nofollow ugc">GitHub project</a> and read about the project itself <a href="http://ct.de/shariff" rel="nofollow ugc">c’t information page</a> (in German).
You can automatically add share buttons to posts, pages, the main blog page, product sites and many more as well as use it as a widget or add the shortcode <code>[shariff]</code> manually to your pages or themes.
