Website Builder can act as your hub, the place where your friends and contacts can see your posts, photos, videos and more. With the option to link to your Facebook, Twitter, Instagram, Pinterest, LinkedIn, YouTube and Google+ on your website, your visitors can be everywhere you are on the web. Being able to cover multiple platforms gives you the opportunity to reach more people, while creating appropriate content for each of your socials (like posting all of your photos on Instagram, and tweeting about your most recent business venture on Twitter). By centrally locating all the links in one place – your new website – you are giving your website visitors a seamless experience. Linking to your social media in your website gives you an advantage in communicating with your visitors; the more they can connect with you and do so in the forum that’s most comfortable to them, the more they’ll engage with your site, and thus you or your business.
These services can host your content on their servers free of charge, but in exchange for that zero cost, your online destination will have a less-than-elegant domain, such as jeffreylwilson.tumblr.com. That might be fine for a personal blog, but it will look too low-rent for a business that wants people to trust it enough to pay for whatever it's selling.
