LucidSW, you can read the information here. [bit.ly ].
Also, I like your idea to attain higher QS and set them to Auto.
I am using manual bidding now. However, started with Auto "Automatic bidding to try maximize clicks for your target budget", and it although gave top position but no conversion happened and wasted money on that.
Even though with manual bidding, conversions aren't happening but there is a control on spending.
The reason why I asked the question earlier because this controlled spending is making ads appear in low positions, which in turn gives impressions with no clicks and lesser CTR.
Now, I am sorting all keywords which have lower ad positions and bidding high on them to gain top ad position also making sure those keywords are having QS >=4. Keywords with QS <=3 have been left out..
Is there any other strategy that works while bidding manually?
