i have 6 years of experience in dfp(small business), new campaign setup, new creative upload, specialized in 3rd party tags, html tags, troubleshooting tags, testing tags, previewing tags, checking if it goes live or not, etc. If its dfa tag, we can just use one url from the tags file. If its other than dfa tag, we have to upload full tag. we have to time stamp for accurate counting. i have the real time experience. if there is any discrepancy, i have good knowledge on how to fix it. I am tulasi ram from india(Bangalore). i dont bother about money, but want to help you on ad ops work.(day to day).
