Where Google Ads stood in March 2026

Google kept pushing automated campaign types as the standard choice. Advertisers who checked their inputs and guardrails regularly held on to better control over costs and the quality of their leads.

Why the inputs mattered so much

Automation magnifies whatever data you feed it. UK businesses with conversions counted twice, out-of-date negative keywords or weak landing pages ended up paying more for poorer results, often without noticing.

Picture an electrician whose form fires a conversion on every page reload. The bidding thinks those campaigns are flying and spends more on them, when the real enquiries haven’t changed.

A quick audit checklist

• Make sure every primary conversion action fires just once for each genuine enquiry or sale.
• Go through your search terms and add negative keywords, AI Max matches included.
• Compare cost per acquisition across campaigns and pause anything that isn’t making you money.
