Depending on the website host you’re using, social panel can be purchased or it comes as a widget setting. If you want to purchase a social toolbar, it’s often offered by an independent company that’s an affiliate to the web host you’re using. Take your time to scout around for the best before making a purchase.
Your decision to purchase a social toolbar depends on what your site is for. Major social sites that have panel for twitter or panel for Instagram are often integrated in a social toolbar, so you don’t have to purchase them separately.
Usually, companies that sell social toolbars offer additional features such as RSS feed and mobile interactive function. Default widgets on a website only allow your readers to share your content to their social media sites. These companies usually offer 24/7 help and support forum where you can have a discussion with other customers.
If you’re looking for a more extensive reach and specific function, then purchasing a social toolbar would be a good choice, especially if you’re running a business via your website.
