This client came to me for ranking and boosting sales, it took me 6-7 months to maintain his acos under 20% and boost sales double to what he was having previously,Below is attached screenshot,

Well, i don't claim I do this overnight or in a week, PPC is an ongoing process and takes a lot of time and requires patience too, but the right strategies do make strong impacts on sales,

These screenshots are of those 8 figure accounts I have been managing in the past, besides that, I have managed many minor and major products too and revived dead listing too via PPC only, with No GAs at all.
