The NGFB and WPSSO plugins have been updated with additional features — three new methods have been added to the
SucomUtil class to process special inline variables. The
%%sharing_url%% variables can be used within any settings value, and will be expanded when the header meta tag array is generated. The handling of content and excerpt text has also been improved to strip encoded HTML tags, which WooCommerce can save in its excerpt (aka Short Description) text.
The NGFB and WPSSO SSB plugins also include a small fix to add the blog ID to the CSS stylesheet file name, allowing multiple blogs to share the same cache folder.
Plugins that add social sharing buttons should be fairly light and fast — they generally don’t need to fetch much information about a page, like an SEO or SMO / SSO plugin does. Here are some example “execution time” metrics from the P3 (Plugin Performance Profiler) plugin, using WP Test Data, and several popular social sharing plugins (along with the WordPress Core and Twenty Fourteen theme for reference). The plugins were configured to include the Facebook, Google+, Twitter, and Pinterest sharing buttons at the bottom of single posts and pages.
Several websites have reviewed WPSSO in the past few months, and the reviews are all very positive…
“If you want to make every tweet, like, share, pin, and +1 count, then you should definitely start using WPSSO on your WordPress site.” — indexwp.com
The WPSSO and NGFB plugins for WordPress are licensed based on the WordPress Site Address. Typically, a Development, Staging, and Production website – for example – would require 3 licenses. In the spirit of helping our fellow developers, we are offering a free license for every license purchased – on all past and future purchases. So, for example, if you purchased a license for example.com (or www.example.com), you can also register dev.example.com using the same Authentication ID. This allows developers to purchase a license, develop a customer’s website, and then change the Site Address upon delivery, without having to purchase an additional license for the production website.
There is a huge variety of available plugins for WordPress — 30,326 plugins as of today — and if you’ve tried more than a few, you’ll have noticed a marked difference in their quality as well (functionality, user interface, stability, etc.). If you know your way around PHP, you should take a moment to browse the source code of a plugin before installing it. You’ll notice quite a difference there as well. ;-) You can view WPSSO’s source code directly from WordPress.org’s SVN repository. If you do, please excuse the lack of comments — it’s on my To-Do list. ;-)
I’ve always kept an eye on performance, and used WordPress’s object and transient caches when possible, along with disk based caching when appropriate. NGFB and WPSSO are fast, but until recently, I’d never compared their performance to other plugins. As I prepare WPSSO v2.4.4 for release later this week, I took some time to double-check its performance and that of a few other plugins as well.
