As an advertising copywriter with 6 years of industry experience, I have had my fair share of writing for several successful online and offline campaigns. I believe that brevity is the key to memorability, so your requirement of catchy ads for LinkedIn is something that interests me. I will tackle the different ads (text, sponsored and InMail) by writing customized content for the medium and the target audience.
If you think that I match your proposition, do write back.
Looking forward,
Yuveline
