Why Are My Google Ads Not Converting? A Diagnostic Checklist
When Google Ads spend money without conversions, the cause is usually tracking, irrelevant search terms, the wrong bidding setup or the landing page. Work through this checklist in order.
Table of contents
Short answer: when Google Ads spend money without conversions, check four areas in order: conversion tracking (is it counting the right things?), search terms (are you paying for irrelevant searches?), bidding and campaign setup (is the system optimizing for the right goal with enough data?), and the landing page and offer (does the page convince people who searched for exactly this?). Most problems sit in the first two.

Step 1: Check your conversion tracking
Before you change a single bid, make sure Google Ads is measuring the right things.
- Conversion actions exist for the outcomes you care about: purchases, form submissions, calls, bookings.
- Primary vs secondary goals are set correctly. If "page view" or "scroll" is a primary goal, Smart Bidding will chase cheap, meaningless actions.
- Each conversion fires once, not on every page refresh. Check for duplicates between Google Ads tags and imported GA4 events.
- Values are correct, especially for e-commerce.
- Calls are tracked (call extensions/assets, website call tracking) if phone calls are your main lead source.
- Offline conversions (sales from leads) are imported where possible, so Google can optimize for leads that become customers.
- Consent mode is set up correctly if you use a cookie banner, so conversions aren't silently lost.
Test by completing a real conversion yourself and checking it appears.
Step 2: Review the search terms report
This is where most wasted spend hides.
- Open the search terms report for the last 30 days, sorted by cost.
- Look for irrelevant searches: jobs, free, DIY, how-to, competitors' support lines, wrong locations, wrong services.
- Add them as negative keywords (at account or campaign level).
- Check match types: broad match without strong conversion data often matches loosely related searches.
- For Performance Max, review search term insights and add account-level negative keywords where available.
Make this a weekly habit. Even well-built accounts drift.
Step 3: Check bidding and campaign setup
- Bid strategy fits your data. Smart Bidding strategies like Maximize Conversions or Target CPA need conversion data. With only a handful of conversions a month, they can struggle.
- Targets are realistic. A target CPA far below your historical cost will throttle volume.
- Learning periods are respected. Don't change strategy, budgets or targets every few days.
- Location settings use "Presence: people in or regularly in your locations" rather than "interest", unless you deliberately want people searching from elsewhere.
- Ad schedule matches when you can answer calls.
- Networks: Search campaigns shouldn't accidentally include Display.
- Budget isn't spread too thin across many campaigns.
Step 4: Check your ads
- Ads match search intent. A search for "emergency plumber" needs an ad about emergency availability, not your company history.
- Ads qualify the click. Mention price ranges, minimums or service areas if they filter out poor-fit clicks.
- Assets (extensions) are complete: sitelinks, callouts, structured snippets, call and location assets.
- Ad strength and Quality Score are reasonable. Google's Quality Score reflects expected click-through rate, ad relevance and landing page experience.
Step 5: Check the landing page
If clicks are relevant but don't convert, look after the click.
- Message match: the headline repeats what the person searched for.
- Speed: the page loads quickly on mobile. Check Core Web Vitals.
- One clear action: call, book, buy, or enquire, visible without scrolling.
- Trust: reviews, accreditations, guarantees, real photos, clear contact details.
- Short forms: ask only for what you need.
- Mobile usability: buttons easy to tap, forms easy to fill, click-to-call works.
- Separate pages for different services rather than sending everyone to the homepage.
Step 6: Check the offer and the follow-up
- Price and offer are competitive for the market. Look at competitors' ads and pages.
- Leads are contacted fast, ideally within minutes.
- Calls are answered; track missed calls.
- Sales team feedback on lead quality is fed back into keyword and negative keyword choices.
Benchmarks to judge your results
LocaliQ/WordStream's search advertising benchmarks put the all-industry averages at roughly:
| Metric | Average |
|---|---|
| Click-through rate | ~6.6% |
| Cost per click | ~$5.40 |
| Conversion rate | ~8% |
| Cost per lead | ~$65–$70 |
Industries vary widely: legal services pay close to $10 per click and well over $100 per lead in the same data, while restaurants pay around $2 per click. Compare against your industry, not the overall average. See how much Google Ads cost for more benchmarks.
Common causes by symptom
| Symptom | Likely cause |
|---|---|
| Lots of clicks, zero conversions recorded | Tracking broken or wrong goal |
| Conversions recorded but no real leads | Wrong conversion action counted, or spam form fills |
| High CPC, low volume | Low Quality Score, narrow keywords, strong competition |
| Spend on irrelevant searches | Broad match, missing negatives, Performance Max without controls |
| Good CTR, poor conversion rate | Landing page, offer or message match |
| Performance dropped suddenly | Tracking change, site change, competitor, policy issue, budget cap |
If you use Performance Max, read Performance Max campaigns: are they worth it? for specific checks.
A worked example
A kitchen showroom spends $4,000 a month on Google Ads with almost no recorded conversions. The diagnosis:
- Tracking: the conversion tag fires on the contact page view, not the form submission, and phone calls aren't tracked. After fixing both, the account records 18 real enquiries in the next month.
- Search terms: about a fifth of spend goes to searches for "kitchen jobs", "IKEA kitchen planner" and DIY terms. Negatives cut that waste.
- Landing page: all ads go to the homepage. A dedicated "fitted kitchens in [town]" page with prices, photos and a booking form doubles the conversion rate.
Same budget, very different results, without touching bids. (Illustrative.)
Fixes ranked by typical impact
| Fix | Typical impact | Effort |
|---|---|---|
| Correct conversion tracking (forms, calls, offline sales) | Very high | Low–medium |
| Negative keywords from search terms | High | Low |
| Dedicated landing pages with message match | High | Medium |
| Location and schedule settings | Medium | Low |
| Bid strategy matched to data volume | Medium | Low |
| Ad copy and assets aligned with intent | Medium | Low |
| Offer improvements | Varies | Medium |
When to pause and rebuild
If tracking has been wrong for months, Smart Bidding has been optimising toward the wrong signals. After fixing tracking, consider resetting to a simpler bid strategy for a few weeks, rebuilding campaign structure around your profitable services, and only returning to automated bidding once accurate conversions accumulate.
The bottom line
Google Ads that don't convert can almost always be diagnosed. Fix tracking first, cut wasted search terms, match bidding to your data, then make sure your ads and landing pages speak directly to what people searched for. Do the search terms review weekly.

Frequently asked questions
Why am I getting clicks but no conversions on Google Ads?
Common reasons are broken or missing conversion tracking, irrelevant search terms from broad match or Performance Max, ads that attract the wrong people, landing pages that don't match the search, and weak offers or trust signals.
How long does it take for Google Ads to start converting?
Search campaigns can convert from the first day, but automated bidding usually needs a learning period of one to two weeks and enough conversion data. Judge a campaign on at least a few weeks and a meaningful number of clicks.
Should I use broad match keywords?
Broad match can work well with Smart Bidding and good conversion data, but it can waste money without them. Accounts with little data often start with phrase and exact match and expand later.
What is a good conversion rate for Google Ads?
It depends on industry and what counts as a conversion. LocaliQ/WordStream's benchmarks put the all-industry average for search at around 8%, with wide variation by industry.
Can Performance Max cause poor conversions?
It can if your conversion goals include low-value actions, your feed or assets are weak, or brand searches inflate results. Check channel and search term insights, exclude brand where appropriate, and feed it accurate conversion values.
