There are many different ways to get connected to advertisers, including sites that act as the middleman.
Use PaidPerTweet
PaidPerTweet connects advertisers with millions of users, from celebrities to bloggers and everyday people. For a fee, advertisers can select a user to issue a tweet from their account. Fees range from $1 a post to $5,000 a post. For example, comedian George Lopez charges $2,000 a tweet. "Camibeth33," a self-described social media junkie, charges just $1 a tweet to reach her 9,000 followers.
Reach Out to Brands Directly
While PaidPerTweet can connect you to advertisers, there is no guarantee anyone will select you out of the millions of users. That's why it makes sense to skip the intermediary and reach out to brands yourself. For example, if you tweet often about beauty products and style trends, connect with growing brands to see if they'd want to get their products in front of your followers. Many times, a groundswell of normal people can launch a brand more successfully than hiring a celebrity spokesperson, as the regular person has more credibility and authenticity.
Post Great Content and Sit Back
If you post great content regularly and build your audience, chances are, brands will come to you. List in your profile that you are PR friendly, and you will likely receive messages from companies asking you to post reviews of their products in return for free trials or a fee.
