Optimize Ongoing Google Search Campaign

My Google Ads Search campaign is already active and driving some clicks, yet I know it can perform far better. The single, clear objective is to increase overall website traffic from an international audience, so every tweak must push toward higher-quality visits at a lower cost per click.

Here is what I need done:

• A quick but thorough audit of the current Search Network setup: keyword structure, match types, ad extensions, negatives, bidding strategy, and conversion tracking.
• Actionable recommendations followed by hands-on implementation of approved changes.
• Brief before-and-after metrics summarising improvements in impressions, clicks, CTR, and average CPC.

All changes should stay within the existing budget and respect current brand voice. A concise report at the end of the optimisation round will be enough; I do not need lengthy slide decks, just clear data that proves the uplift.
