Key takeaways
- Audit tracking first. If conversions are wrong, every bidding and reporting decision built on them is wrong too.
- Then review structure, search terms, bidding strategy, ads and landing pages in that order.
- Optimization score is a prompt list, not a goal. Apply suggestions that fit your business and ignore the rest.
- Record changes and judge them over a full cycle, not a few days.
01
Is conversion tracking measuring the right thing?
Start here because Smart Bidding optimises toward the conversions you report. Check that each conversion action reflects a real business outcome, such as a qualified form or a booked call, not a page view or a click on a phone number you never answer. Look for duplicates, misfiring tags and conversions imported from the CRM that disagree with the ad platform.
Google's conversion tracking guide explains the tag and import options. If sales close offline, bring that data back so bidding can learn from revenue rather than raw leads.
02
What should you check in structure, queries and bidding?
Look at how campaigns and ad groups map to intent. Mixed intent in one ad group makes ad copy vague. Review the search terms report for irrelevant queries, add negatives, and note wasteful match types. Quality Score components, namely expected click-through rate, ad relevance and landing page experience, point to where relevance is weak, though Google calls Quality Score a diagnostic tool rather than a KPI to optimise.
Smart Bidding needs conversion tracking and enough conversion data to learn, and Google recommends judging results over a month or longer, so avoid frequent setting changes. Check the bidding strategy matches the goal and that targets are not set so tight that spend stops.
- Conversion actions map to qualified outcomes
- No duplicate or misfiring tags
- Campaigns split by intent and location
- Search terms reviewed; negatives maintained
- Bid strategy matches goal and data volume
- Budget limited campaigns identified
03
How do you audit ads and landing pages?
Read the ads as a buyer. Each ad group should have copy that answers the query and a clear next step, with assets such as sitelinks and callouts that are accurate. Then open the landing page on a phone: does it match the promise, load quickly and make the action obvious?
Landing pages often hold the biggest gain. Fixing a form or message mismatch lifts every click you already pay for.
| Area | Check | Typical leak |
|---|---|---|
| Tracking | Tag firing, import, duplicates | Optimising to junk conversions |
| Structure | Intent and location split | One ad group for everything |
| Queries | Search terms, negatives | Irrelevant broad matches |
| Bidding | Strategy vs. goal and volume | Tight targets starving spend |
| Ads | Relevance, assets, claims | Generic copy |
| Landing page | Message match, speed, form | Visitors leave without acting |
04
How should you treat optimization score and make changes?
Google describes optimization score as an estimate of how well an account is set up to perform, with recommendations to raise it. Treat it as a checklist to evaluate, not a target. Some suggestions, like broad match or higher budgets, may not suit your goals.
Change a few things at a time, log them with dates and review after a full conversion cycle. Rapid edits make it impossible to know what worked.
