Hi,
I just read all the details about your job posting moments ago. From your job description, I came to understand that you need a pixel setup for Facebook to track website visitors.
I wanted to give you a shout out as I have 4 years of experience working as a Google/Facebook Certified Specialist having worked with hundreds of clients across the world in various industries.
Recently I have completed the Optimization of Facebook Ad for one of my Freelancer clients and I assure you that you will track each and every website visitors and retarget them with the help of Facebook Conversions.
Looking forward to your reply
Thanks
Piyush
