Recently, a German travel client used more than 3900 keyword constraints in order to influence its overall performance. A keyword constraint is the maximum/minimum CPC or maximum/minimum position rule for each individual keywords. Soon, 90% of the daily budget was used to fulfill these constraint targets and only 10% of the budget was actually used to optimize keywords and increase real performance.
By taking away the majority of constraints, the complete daily budget was available to have the keyword market develop and to use the data generated from Efficient Frontier's portfolio optimization technology. Monitoring the performance very intensely, the following development was encountered.
When looking at Efficient Frontier's simulations this step became even more obvious. When the constraints were taken away, uplifts can be expected immediately. In this case, we saw an ROI increase of 96% (day to day) and 45% (week to week) just by taking away keyword limitations and letting the invisible hand of the optimizer take over. Since then, the free market environment has allowed the performance to improve continuously.
So if ROI is your key objective, resist the need to seek the top SERPs positions and liberate your keywords from their constraints to improve performance and ROI.
