BACKGROUND
Lebara Mobile is an Australian market leader in SIM cards for national and international calls. The client operates seasonally, with peak season between November and February, and off-peak during winter.
FACTS
It’s important to emphasise that we didn’t increase the spend on brand terms. In fact, the spend of brand terms was halved during this period. We didn’t change the proportion of cost between the brand and general keywords. The majority of promotions were based on our client’s decisions; we provided the analyses, advising which product to focus on.
How we did it
Step 1.
As their brand name is extremely competitive, we needed to use the brand name as a keyword as well. We remarketed to these visitors of the brand campaign through the Display Network, which proved very effective. We attracted new visitors and captured traffic via Similar Audience, Shopping campaigns and General/competitor keywords, retargeting them with Search, Shopping and Display Network.
Step 2.
We restructured the campaigns. On the Search Network, we created more ad groups for each specific phrase. We used cross exclusions, omitting the irrelevant phrases.
Step 3.
We broke down the Shopping campaign by products. Through this we increased the bid of specific products which were highlighted in the current promotion.
Step 4.
On the Display Network we created different remarketing lists to monitor what was performing best. We targeted devices separately because we believed people converted differently depending on device.
Step 5.
We broke location targeting into states and major cities, to improve the ease with which bid adjustments could be made.
RESULTS

Cost and all conversion value trends:

All conversion value/cost trends:

Between July 1st – September 30th and May 1st – June 30th, there was an additional 1,726.45 conversions: a 140.79% growth.

We could decrease the cost/conversion by 49.54% during this period which meant this metric reduced from $32.31 to $16.25.

We increased the conversion rate by 115.62%; from 2.22% to 4.80%.

All conversion value per cost increased from 2.98 to 5.60, which is an incredibly impressive increase of 88%. This means that for every dollar spent the return at the end of this optimisation period was 88% greater.
