So here are a few ways you can try to improve on this lack of activity by engaging with your followers...
Ask your followers to subscribe
You don't get if you don't ask. Post an update to your Facebook or Twitter account reminding your followers where to go to subscribe. It is also a good idea to show previous examples of your campaigns next to your signup form - just to show subscribers what they are signing up to and how this may interest them further.
Interact with your fans
Maybe recommend a product for a rainy Monday afternoon or simply show them a new product that you have in stock. This can help grow activity on your posts and also grow an awareness of your brand. It's also a great time to ask for feedback or reviews on product X.
Run a competition
A great way to gain exposure is to run a competition. You can give away a product or service you provide or even vouchers for high street stores. The competition could entail getting your followers to like or retweet your status to enter, this in turn will increase your overall reach. Just make sure you have a page on your website with the rules of the competition, details of the prizes and when the competition will close. Or if you are running the competition via Facebook or Twitter make sure you adhere to their rules and regulations.
Offer a discount
Create a discount code on your website and share it on your social networking sites, giving something back to your fans and attempt to encourage new customers. You could even create a welcome email that contains the discount code as this would encourage more people to subscribe to your newsletter.
Think ahead to any public holidays that are coming up, maybe you'd like to create a campaign themed around Hallowen or maybe try posting an update in the evening or over a weekend. This can be anything from announcing a new feature in your system to promoting a new blog post or how to guide.
By using a free application like Tweetdeck or Hootsuite, you can manage all your social media accounts under one roof. This also allows you to create social media updates in advance so you don't have to be sitting at the computer over the weekend. If you use Google Analytics you can see where most of your traffic originates from and at what time. This can be something to work from in the future if a certain time is more popular than others.
Share links to blogs or guides
Share links on Facebook and Twitter to any recent blogs or guides you have written, maybe you can post earlier blog posts to give them some attention. As mentioned above, if you use a social media dashboard application manager you can schedule your updates for the week ahead!
