Google’s ad preview tool: where to find it and how to use it

Branded creative office supplies with glowing bulb

The Ad Preview and Diagnosis tool lives inside Google Ads under Tools > Troubleshooting > Ad preview and diagnosis, and it shows exactly what your ad looks like for a specific search term, location, language, and device, without ever recording an impression. That last part matters more than most advertisers realise: this is a genuine risk-free way to check delivery. It won’t touch your budget, your click-through rate, or your Ad Rank data in any way.

Beyond the visual check, the tool returns diagnostic messages that explain why an ad isn’t showing where you expect it to. That’s the real value: it doesn’t just show you a picture, it tells you what’s broken.

Here’s what it covers in one pass:

Location, language, and device simulation — see your ad exactly as a shopper in Manchester on a mobile browser would see it, or swap to Warsaw on desktop.
Diagnostic feedback — messages covering budget exhaustion, low Ad Rank, targeting mismatches, and policy issues.
Zero impact on live metrics — no impressions logged, no budget spent, no effect on your account’s real performance data.

At Radka Advertising, this tool sits at the centre of how we quality-check every campaign before it goes live for a client, precisely because it lets us catch problems while they’re still free to fix using Valiz campaign validation tooling.

How to use the ad preview tool step by step

Opening the tool is straightforward once you know where Google has tucked it away. From your Google Ads account, click the wrench icon (Tools & Settings) in the top navigation, then look under the Troubleshooting column for Ad preview and diagnosis. Google also maintains a direct anonymous access point for quick checks outside a logged-in session, plus an in-account diagnostic endpoint that pulls live account context into the simulation.

Once you’re in, running a preview takes four decisions and one click.

Enter your search term exactly as a customer would type it, not just your target keyword in isolation.
Set the location down to city or postcode level if you’re running local campaigns, since delivery can vary street by street in dense markets.
Choose the language that matches your ad group’s targeting, not necessarily your own browser language.
Select the device — desktop, mobile, or tablet — because rendering and eligibility can differ across each.
Click Preview and read the result alongside any diagnostic message beneath it.

The tool also supports Share this search, a bookmarkable URL that reproduces the same simulated result for a colleague or client. That’s a far better habit than manually searching Google.com to “just check” your ad is live. Manual searches record real impressions, and if you never click your own ad, Google’s system may start showing it to you less over time, which quietly distorts the exact metric you were trying to verify.

Pro Tip: Save your most common geo/device combinations as bookmarked preview searches. If you run campaigns across the UK and multiple Eastern European markets, a handful of saved links turns a five-minute manual check into a ten-second one.

How to use the ad preview tool step by step — overview diagram

What do the diagnostic messages actually mean?

The preview tool doesn’t just show or hide your ad. It names the reason, and each reason points to a different fix.

“Ad showing” — your ad is eligible and rendering for that exact search context. No action needed.
“Not triggered: budget exhausted” — your daily budget has already been spent for that campaign; check pacing or raise the cap.
“Low Ad Rank” — your bid, ad quality, or landing page relevance isn’t clearing the auction threshold for that query.
“Campaign paused” — the campaign or ad group is switched off, sometimes accidentally left that way after testing.
“Policy violation” — the ad has been disapproved or limited, often for restricted content or a landing page issue.
“Keyword not in account” — the search term you entered simply isn’t in any active ad group’s targeting.

Ad Rank itself is built from your bid, the expected quality of your ad and landing page, Ad Rank thresholds for that auction, the competitive context of the search, and the expected impact of extensions and other ad formats. A low bid can sometimes be outweighed by strong quality signals, and vice versa, which is why two advertisers bidding the same amount can get very different delivery.

Diagnosis shown	Probable cause	Corrective action
Ad showing, but poor position	Ad Rank borderline against competitors	Improve landing page relevance or raise bid modestly
Not triggered: budget exhausted	Daily budget capped too low for demand	Increase budget or adjust ad scheduling
Not triggered: low Ad Rank	Weak bid/quality combination	Review keyword relevance, ad copy, and Quality Score
Not triggered: policy violation	Disapproved ad or landing page issue	Check Policy Manager and resolve the flagged element
Not triggered: keyword not in account	Search term outside current targeting	Add as a keyword or broaden match type

Pro Tip: Before troubleshooting anything at keyword level, check your account status first. A billing hold, an unfinished verification step, or a suspension will block every ad from serving regardless of how well your keywords or bids are set up.

When should you use the preview tool instead of a manual search?

The preview tool earns its place in four recurring scenarios: pre-launch verification before a campaign goes live, geo and device validation across markets you can’t physically visit, checking how extensions and creative assets render together, and troubleshooting a specific “why isn’t my ad showing” complaint from a client.

Pre-launch checks catch broken targeting or policy issues before a single pound is spent.
Multi-market validation lets you confirm an ad renders correctly in, say, Poland or Romania without booking a flight or borrowing a VPN.
Extension and creative QA confirms sitelinks, callouts, and images are actually eligible to show, not just configured.
Delivery troubleshooting turns a vague complaint into a specific diagnostic message you can act on.

The tool has real limits, though. It’s a simulation, which means it can’t fully replicate live real-time bidding dynamics or the personalisation Google applies based on an individual searcher’s history. If the tool shows your ad, that’s a strong signal of eligibility, not a guarantee of exactly how it will render for every real user at every moment.

That’s also precisely why searching manually is the wrong instinct. A manual search on Google.com logs a real impression whether or not you click, and repeated searches with no clicks can nudge the algorithm to show your ads less often to that account or device over time. You end up degrading the very signal you were trying to inspect.

Pro Tip: Pair the preview tool with Auction Insights. The preview confirms technical eligibility; Auction Insights tells you where you stand competitively against the advertisers you’re actually up against.

Official diagnosis tool vs visual mockup generators

Not every check needs a full diagnostic run. Sometimes you just need a clean image to show a client before copy is even finalised, and that’s a different job entirely.

The official Google tool and independent mockup generators solve different problems. One tells you whether an ad will actually serve; the other shows you what it will look like once it does. Confusing the two leads to wasted time, either running diagnostics for a simple layout question or asking a mockup tool to answer a delivery question it was never built to answer.

Criteria	Official Ad Preview & Diagnosis tool	Visual mockup generators
Best for	Diagnosing why an ad isn’t serving	Client-facing visual layouts and sign-off
Risk to account metrics	None, no impressions recorded	None, but no real auction data either
Accuracy for real-world delivery	High, reflects actual eligibility signals	Illustrative only, not auction-tested
Ease of use / setup	A few clicks inside Google Ads	Usually instant, no login required

Independent mockup generators, such as the Google Ads mockup tools built by marketing specialists like Andrew.marketing, are popular for exactly this reason. They produce polished, shareable visuals and let you preview several ad variants side by side, which is genuinely useful for presentations. What they don’t do is simulate the auction, so treat their output as a design reference, never as proof your ad will actually serve.

If the question is “will this ad show for this search,” use Google’s own tool. If the question is “does this ad look good and on-brand,” a mockup generator gets you there faster.

The pre-launch checklist worth running every time

A short, disciplined checklist before launch catches the mistakes that cost real budget in the first hour a campaign goes live.

Confirm keyword triggers by running previews on your top five search terms, not just your broadest match keyword.
Verify location and language settings match your actual target markets, especially if you’re running campaigns across the UK and Eastern Europe simultaneously.
Check device layouts on both mobile and desktop, since headline truncation and extension display can differ.
Inspect ad extensions and final URLs, confirming sitelinks and callouts are eligible to show and every link resolves correctly.
Check budget and campaign status to rule out a paused ad group or an exhausted daily cap before assuming a targeting fault.

A few quick sanity checks round this out:

If sitelinks aren’t appearing in preview, check their approval status individually. A single disapproved sitelink can sometimes suppress the whole set.
Confirm final URLs haven’t been left pointing at a staging environment.
Re-run the preview after any bid or budget change; delivery eligibility can shift within minutes.

How Radka Advertising builds the preview tool into campaign QA

Every campaign we launch runs through the same rhythm: draft the copy, preview and diagnose it against each target market, quality-check extensions and landing pages, then hand off for launch or send it back for one more pass. For clients running across the UK and Eastern European markets at once, that market-by-market preview step catches language and geo mismatches that a single “does it look right” glance would miss entirely.

When a client asks why an ad hasn’t appeared for a specific search, we don’t guess. We run the exact search term, location, and device through the diagnosis tool and hand them the actual reason, not a theory.

We also lean on Share this search links during client review. Instead of describing what a search result looks like in Warsaw versus London, we send the client the live simulated view, and they see precisely what we saw. It’s a small habit, but it removes a lot of back-and-forth from campaign sign-off. You can see how this discipline plays out across different industries in our case studies.

Pro Tip: Bundle your saved preview links by market before a multi-country launch. A folder of five bookmarked searches for five markets turns a scattered review call into a five-minute walkthrough.

Why we prioritise the official diagnosis tool over guesswork

The conventional advice you’ll find in most PPC guides treats the preview tool as a nice-to-have, a box to tick after the real work is done. We’d argue it’s closer to the opposite: it’s the cheapest insurance policy in the entire launch process, because every diagnostic message it returns is a problem you get to fix before it costs you a single click.

Where mockup generators earn their place is earlier in the process, during design and client sign-off, when the question is aesthetic rather than technical. Using one to confirm delivery would be like judging whether a shop is open by looking at a photograph of its shopfront. The photograph might be accurate, or it might be from last year. The official tool is the one checking the door right now.

What actually separates agencies that avoid costly launch surprises from those that don’t usually isn’t tooling sophistication. It’s whether checking delivery became a habit or stayed a one-off task nobody remembered to repeat after the first campaign.

Get campaign checks and troubleshooting handled for you

Running preview and diagnosis checks manually works well when you have the time to do it market by market, campaign by campaign. Where Radka Advertising adds real value is when that checking needs to happen across multiple countries, languages, and ad accounts without eating a full day of your week. As a full-service agency, we build preview and diagnosis checks directly into campaign QA, so low Ad Rank issues, blocked extensions, and targeting mismatches get caught before launch, not after your first client complaint.

If you’ve run a preview and found a diagnostic message you’re not sure how to fix, our campaign audit service is built for exactly that. For businesses juggling UK and Eastern European markets at once, we also handle the bilingual side of ad copy and geo-targeting that preview checks alone can’t fix. Book a diagnostic review through our main services page and get a second set of eyes on your account before you spend another pound.

FAQ

Where is the ad preview tool in Google Ads?

It sits under Tools & Settings > Troubleshooting > Ad preview and diagnosis inside your Google Ads account, alongside an anonymous access point for quick checks.

How do I preview an ad without affecting my campaign stats?

Use the official Ad Preview and Diagnosis tool rather than a live search. It simulates results without recording an impression, so your budget and metrics stay untouched.

What are Google’s ad tools used for?

Google Ads includes several tools for planning, monitoring, and troubleshooting campaigns, with the Ad Preview and Diagnosis tool specifically built to check whether and why an ad is or isn’t showing for a given search.

How can I tell if someone is running Google Ads?

Searching manually for a competitor’s ads is unreliable and can distort your own account’s ad-serving signals over time, since repeated searches without clicks affect what the algorithm shows you. A more reliable route is checking Google’s Ads Transparency Center rather than relying on manual searches.

Should I use a mockup generator or the official diagnosis tool?

Use the official tool when you need to know whether an ad will actually serve; use a mockup generator only for visual layout checks and client presentations, since mockups carry no auction accuracy.
