I am having more than 400 Campaign with ₹2 Cr Monthly Budget, I lost my Search Imp. Share from 90% to 10% , and CTR from 25% to 10%, these matrics were going down drastically.
It was very difficult to know which campaign should be optimized because the number of campaigns are huge.
I took various steps to get my lost SIS and CTR, I failed and failed upto 3 weeks, no hope.
but finally i used below metrics and have made below rules on campaign level.
After applying below rules, I finally got my SIS and CTR back to normal.
1. Ad CTR >=20%–All Time Data—Resume
2. Ads with CPUL >=2000 & Ad CTR<=19.99%—All Time Data—Pause
3. KW CTR >=20% –All Time dData—Resume
4. Adgroup CTR>=20% & CPUL<=1000—All Time Data —Resume
