In building an ideal audience, you must constantly keep every subscriber up to date with news and important resources from your blog. You wouldn’t expect readers to keep coming back checking out the latest posts on their own because you want active subscribers, not just the stop-by visitors.
When it comes to gathering collections of people (as many as you want them), social media is excellent for this. Once you’ve set up a landing page and, probably, a popup form on your blog, you will need to start collecting subscribers.
You have all these platforms like Facebook, Twitter, YouTube, RSS feeds and email at your disposal to leverage and you can continue having as many followers transitioned into subscribers as possible for your business blog. Social media is particularly great for this, yet you wouldn’t be targeting there.
If you really want to build a large following through social media, you should be focusing on Facebook, Pinterest and Twitter. These are the most prominent platforms to achieve that.
