Google Ads is the fastest way to buy demand and the fastest way to waste money, and the difference between those two outcomes is mostly structural. Accounts that perform are usually not cleverer than accounts that do not — they are organised so that optimisation is possible.
The auction, briefly
You do not pay your bid. Position is determined by Ad Rank, which combines your bid with expected click-through rate, ad relevance and landing page experience. This is why the highest bidder does not automatically win, and why improving relevance lowers what you pay for the same position.
It also explains something that confuses new advertisers: a competitor bidding less than you can appear above you. Their ad and landing page are simply more relevant to that query.
Campaign types, and what each is for
| Type | Use it for | Watch for |
|---|---|---|
| Search | Capturing existing intent | Broad match spending on loosely related queries |
| Performance Max | Automated reach across inventory | Limited visibility into where spend actually goes |
| Shopping | Retail product discovery | Feed quality determines everything |
| Display | Reach and remarketing | Placement quality; exclusions matter |
| YouTube | Demand generation | Measurement is harder; expect assisted rather than last-click |
For most businesses starting out, Search is where the money should go. It captures people who have already declared what they want, which is the cheapest demand there is.
Fix measurement before touching spend
Optimising against inaccurate conversion data does not produce a neutral outcome — it actively makes things worse, because automated bidding will confidently allocate budget toward the wrong signal.
- Confirm conversions fire once, on the right action, and are not double-counting
- Separate genuine leads from low-value actions like newsletter signups
- Assign values to conversions so bidding can distinguish between them
- Check that offline outcomes — the enquiry that became a sale — feed back where possible
Where budgets leak
- Broad match without a negative keyword list that is actually maintained
- Bidding on your own brand when you already rank first organically and face no competitor bids
- Sending every ad to the homepage instead of a relevant page
- Campaigns running in locations you cannot serve
- Ad schedules ignoring when your team can actually answer the phone
The landing page is part of the campaign
A meaningful share of poor Google Ads performance is not a Google Ads problem. If the page loads slowly, does not match the promise in the ad, or buries the action, no amount of bid management fixes it.
