Campaign: "Search – Solar – IDF"

Overall, the number of conversions increased by +25%, while costs decreased by -18%. Distribution also improved, with impressions up +28,5% and clicks up +16%. However, last week’s -12% budget cut for the campaign led to a roughly 20% drop in impression rate.
The ad group "Battery SPC – Solar – IDF" showed concerning performance during the week of June 2, 2025, with conversions down -20% and click-through rate (CTR) down (-29%), despite a +27% increase in impressions. While the addition of new keywords allowed for more traffic coverage, the headlines and descriptions now need to be updated as well.
In contrast, the ad group "Battery ERU – Solar – IDF" saw significant performance improvements, with conversions up +200% and conversion rate up +77%, for a +16% increase in cost. These results are largely attributed to the addition of negative keywords and new targeted keywords.

Campaign: "Search – Panels & Installations – IDF"

The number of conversions increased from 1 to 5 during the week of June 2, 2025, compared to the previous week — despite a drop in both clicks and impressions.
These positive results are largely attributed to changes in the keywords for the "DSA - Solar - IDF" ad group, including the addition of negative keywords such as "how do photovoltaic panels work" and "solar panel for electric fence", along with new exact-match keywords.
Additionally, the landing page change made last week appears to have been effective, as it is helping drive more conversions.

Other notable metrics

The budget reduction and pausing of an ad group in the "Search – Panels & Installations – IDF" campaign appear to have had a positive impact on performance, with conversions increasing to 3 from 1 the previous week.
Additionally, distribution metrics remained stable despite a -20% drop in costs.

Strategic Opportunities

Here are my strategic recommendations for account-level campaign adjustments:
Campaign "Brand – CFE":
Stop using the Maximize Clicks bidding strategy in favor of Maximize Conversions. Create a dedicated portfolio bidding strategy for this campaign, with a target CPA of 40€ and a maximum CPC of 2€.
Campaign "Brand – JS – FR":
Lower the maximum CPC to 1.10€ for the Broad Match ad group, and to 1.00€ for the Exact Match Brand ad group.
