Search engines like Google Search use a page’s loading time as a signal when they compute that page’s ranking in their search engine results. Webmasters have a lot to tweak, from the server backbone to the scripts they use and embed, and the images and media they post; Everything has an impact on the page loading time. Social media buttons have become very popular with webmasters in recent years. The majority implements the buttons either with the help of plugins or by copying and pasting the code that social networks like Facebook offer directly.
The following solution has been created by Daniel Pataki. It is a solution for WordPress, if you use a different script or software you may need to modify the code accordingly.
The code consists of two parts. First CSS code that you need to add to your blog’s stylesheet, and then the code that displays the links to the social networking sites on the website.
You need the following sprite image that contains all four icons. This speeds up the loading time as only one image needs to be loaded instead of four separate ones. Place it in the /img/ directory of your theme folder or alter the background:url code to place it somewhere else.
The functionality should be available immediately. Users who click on a social networking icon are taken to the selected site where they can post about the web page that they have originated from. The page url is automatically included in the post.
Update: Have added rel=”nofollow” to all external links.
