Why?

When someone decides to follow you on Twitter, you gain a chance to engage with that person over time. Each time you engage with your followers, you create new opportunities for them to share content, make purchases or tell others about their positive experiences.

Below are a few simple questions you’ll want to ask yourself when getting started:

1. Who do I want to follow my business? Think about the different groups of customers that you would like to purchase your product or service. Make sure your targeting selections line up with these groups.
2. How much am I willing to pay for each new follower? The cost per follower on Twitter is not fixed - it depends on the size of the audience you're targeting, your bid, and other advertisers' demand for that audience. A bid of $2.50 - $3.50 is recommended based on historical averages, but you'll receive real time bid guiddance in your campaign setup. 
3. How many new followers do I want to gain? Set a goal to help you decide on a budget. This might be a regular daily gain or a specific number by a certain date. For example, if you want to gain at least 10 followers a day, then you would set your daily budget to $30 and your bid to $3.00.

When?

Because follower campaigns boost your follower growth, they are best used when you are more likely to be discoverable to people who are existing or prospective customers on Twitter. A robust follower base amplifies the performance when you run other goal based campaigns.

• Drive purchases, leads, downloads, and signups: By choosing to follow you, Twitter users are demonstrating an interest in your product. You have an opportunity to connect with them in meaningful ways to drive actions.
• Increase brand awareness and word of mouth sharing: When you Tweet valuable content, Twitter makes it easy for your followers to share it with their friends through Retweets, driving increase reach and awareness.
• Drive web traffic: Once you acquire a paid follower you have the opportunity to engage with them everyday, for free, with your organic Tweets. Your followers are the mostly like to see your Tweets and spend time on your website.

Twitter’s cost-per-action pricing ensures you only pay for the specific actions you are looking to drive. 

When you run a Followers campaign, you will only be charged for the follows you acquire from that campaign. All other actions and engagements (impressions, replies and Retweets for example) are free.

The cost you pay per follower in your Followers campaign will depend on the budget and bid you set for your campaign, as well as the targeting you select. A bid of $2.50 - $3.50 is recommended based on historical averages, but you'll receive real time bid guiddance in your campaign setup. More on Twitter Ads pricing.

Details:

When setting up your Followers campaign you can select between automatic or target bidding as your bid type. We suggest selecting the target bid option since this will give you the flexibility to successfully bid on follows from users who are especially likely to follow your account, while staying near or below your target costs per follow. When you setup your campaign and input your bid, think of your target bid as how much you're willing to pay per follow.

It's important to think carefully about the value each follow brings to your business. The recommended bid is a good indicator of the amount you will need to bid for your campaign to reach its goal. You will never be charged more than your bid and advertisers are often charged less.  However, if your bid is not competitive relative to other advertisers, your campaign may not serve.

In addition to controlling the amount you pay per action, you also have complete control over the amount you spend overall. After setting your bid, you are prompted to enter a total budget for the campaign and, optionally, a daily budget as well. When your overall budget is reached, you campaign will stop serving until you increase the budget. When your daily budget is reached, your campaign will stop serving until the next day.
