"I am most experienced working with the usual suspects; Instagram, Facebook, and Twitter. Although very effective, I have found a lot of success with other channels such as Pinterest and LinkedIn. These content-driven social sites have boosted our agency's campaign exposure, and increased the number of click-throughs onto many of our campaign landing pages."
"My social media knowledge is strong, and I have expertise in LinkedIn, Pinterest, Instagram, Twitter, Facebook, and more. Of all the channels, I find Instagram to be the most effective for the audience my current employer is targeting. I have worked hard to crack the code on IGTV as well as InstaStories, which have been quite lucrative for business."
