Most business owners running Google Ads have no idea what their competitors are actually saying in their ads. They assume they need expensive tools to find out, or that the information simply is not available. Neither is true.
You can see every ad your competitors are currently running on Google, completely free, in under five minutes. The same information that used to require a paid intelligence tool subscription is now publicly available through Google’s own Ad Transparency Center. And once you know what your competitors are running, that information can directly improve your own campaigns, from the keywords you target to the ad copy you write to the offers you promote.
Companies that actively monitor competitor Google Ads see 25% higher click-through rates and 18% lower cost-per-click compared to those that do not, according to 2025 WordStream data. This guide shows you exactly how to do it, using free tools that are available to any Australian business owner right now.
If you are new to Google Ads and want to understand how campaigns are structured before diving into competitor research, our Google Ads foundations guide is worth reading first.

Method 1: Google Ads Transparency Center (Free, No Login Required)
The Google Ads Transparency Center is the single most powerful free tool available for competitor ad research, and most Australian advertisers have never heard of it.
The Transparency Center is a searchable database of every verified advertiser on Google platforms. It shows you every ad an advertiser is currently running, which formats they are using including video, image, and text, which regions they are targeting, and when the ads were last shown. It covers the entire Google ecosystem: Search, YouTube, Display, and Gmail.
It was originally designed for political ad accountability and regulatory compliance, but it has become one of the most useful competitive intelligence tools available to any marketer. It is completely free and requires no login or Google Ads account to access.
How to Use It
Go to adstransparency.google.com. You will see a search bar. You can search by advertiser name or by website URL. Searching by URL is usually more reliable because many businesses advertise under their parent company or agency name rather than their brand name.
Type in your competitor’s website domain, such as competitorbusiness.com.au, and you will see every ad they are currently running or have recently run across Google’s platforms.
From here you can filter by:
- Ad format: Text, image, or video
- Region: Australia specifically, or any other country
- Date range: To see how long specific ads have been running
The Google Ads Transparency Center allows advertisers to view active ads from any verified business, providing valuable insights into messaging, offers and creative strategies being used across the market.
What to Look For
When you pull up a competitor’s ads, you are looking for patterns and insights rather than individual ads to copy. Specifically:
What formats are they prioritising? If a competitor is running dozens of video ads but only a handful of text ads, they have clearly found success with video. If they are running only text search ads with no display or YouTube presence, their focus is on intent-driven search.
What offers and messages keep appearing? The ads a competitor runs consistently over a long period are the ones that are working for them. A promotional offer that keeps appearing month after month is almost certainly converting. A headline format that appears across multiple ad variations has been tested and retained.
What landing pages do they use? Click on any ad in the Transparency Center and you can see the destination URL. This tells you whether they are sending traffic to their homepage, a specific service page, or a dedicated landing page. A competitor consistently using a dedicated landing page for paid traffic has almost certainly found it performs better than a generic page.
What geographic targeting are they using? The region filter lets you see whether they are running Australia-wide campaigns or targeting specific cities and regions. If a Brisbane competitor is also running ads in Sydney and Melbourne, that tells you something about their growth plans and their confidence in their offer.
What the Transparency Center does not show you is performance data. You will not see metrics like spend, click-through rate, or conversions. Use it for creative intelligence, not benchmarking.
Method 2: Google Auction Insights (Free, Requires Active Google Ads Campaigns)
If you are already running Google Ads, you have access to a second free tool that gives you different and in some ways more valuable data: Auction Insights.
Google Ads Auction Insights provides first-party data about who you actually compete against in real auctions. This free tool shows impression share, overlap rate, position above rate, and top of page rate for each competitor.
The key difference from the Transparency Center is that Auction Insights only shows you competitors who are bidding on the same keywords as you, in the same auctions you are participating in. This makes the competitor list much more relevant and targeted.
How to Access It
In your Google Ads account, go to any campaign, ad group, or keyword. Click on the three-dot menu or find Auction Insights in the left navigation. You will see a list of competitor domains alongside four metrics:
Impression share: What percentage of available impressions each competitor is winning. A competitor with 80% impression share is showing up for almost every search. A competitor with 15% share is appearing occasionally.
Overlap rate: How often your ads and a competitor’s ads are showing in the same auction. A high overlap rate means you are competing directly for the same searches.
Position above rate: How often a competitor’s ad appears above yours when you both show up in the same auction.
Top of page rate: How often a competitor’s ad appears at the very top of the search results page.
Auction Insights provides a direct view of the advertisers competing for the same searches, helping identify who dominates impression share and where opportunities exist to improve visibility.
How to Use Auction Insights
Auction Insights is most useful for understanding the competitive intensity of your campaigns. If a competitor has a much higher impression share than you, they are either bidding more aggressively, have a higher Quality Score, or both. If a competitor consistently appears above you, understanding why, whether it is bid strategy, ad relevance, or landing page experience, can directly inform improvements to your own account.
Cross-reference the competitors you see in Auction Insights with what you find in the Transparency Center. If a competitor has high impression share and is consistently running the same ad variations over months, that combination tells you they have found a formula that is working.
Our article on Google Ads Quality Score explains how Quality Score affects your ad position and cost per click, which directly influences where you appear relative to competitors in the auction.
Method 3: Paid Tools for Deeper Intelligence
The free tools above cover the most important bases. Paid tools like Semrush and SpyFu add a layer of keyword-level intelligence that the free options do not provide.
Semrush Advertising Research: Enter a competitor’s domain and see the keywords they are bidding on, their estimated monthly ad spend, their top performing ad copy, and how their paid keyword strategy has changed over time. This is estimated data rather than actual figures, but it gives you directional insight into where competitors are investing.
SpyFu: Similar to Semrush but with a focus specifically on paid search competitor research. SpyFu shows you the keywords a competitor has been bidding on historically, which can reveal patterns and seasonal strategies that current data alone does not show.
Google Keyword Planner: While not a competitor intelligence tool specifically, Keyword Planner lets you see the estimated competition level and cost per click for keywords you are considering. High competition and high CPC on a keyword is indirect evidence that other advertisers are finding it profitable.
For a full breakdown of what Semrush and Ahrefs offer for both paid and organic research, our article on paid keyword research tools covers their features, pricing, and which is right for different business sizes. For context on what Google Ads management typically costs in Australia, our Google Ads management cost guide covers agency fees, ad spend benchmarks, and what to expect at different budget levels.
Keyword research tools help advertisers understand search demand, competition levels and potential advertising costs before investing budget into new campaigns.
How to Actually Use What You Find
Gathering competitor ad intelligence is only useful if it informs decisions. Here is how to turn what you find into action.
Identify Angles You Are Missing
Look at the offers and messages your competitors are leading with. Are they emphasising price, speed, guarantee, or expertise? If multiple competitors are all leading with the same message, there may be an opportunity to differentiate. If you see a message or offer that you could credibly match but are not currently using, test it.
Find Keywords They Are Targeting That You Are Not
Paid tool data and Auction Insights can reveal keyword gaps in your own campaigns. If a competitor is bidding on a term you are not and that term appears in multiple ad variations over time, it is worth investigating whether you should be targeting it too.
Use Long-Running Ads as Creative Inspiration
An ad that has been running for three months or more has almost certainly been retained because it is performing. This is your strongest signal about what messaging resonates in your market. Use it as inspiration for your own copy, not as a template to copy, but as evidence of what kind of language, offer, or approach works with your shared audience.
Identify Gaps in Their Strategy
Equally important is what your competitors are not doing. If none of them are running YouTube ads, there may be an opportunity to build brand awareness in a space they have vacated. If their ads are all focused on the same service but they offer others, those other services might be undercompeted keywords worth targeting.
Improve Your Landing Pages
Seeing where competitors send their paid traffic is one of the most underutilised insights from this research. If every competitor is using a dedicated landing page for a specific service but you are sending traffic to your homepage, that is likely a conversion rate problem worth addressing. Our article on why your Google Ads need a landing page covers exactly what a high-converting landing page needs and why it matters for both cost per click and conversion rate.
What Not to Do
Do not copy competitor ads directly. Beyond being poor practice, it is rarely effective. Your competitors’ ads work in the context of their brand, their offer, and their audience. Copying the words without the underlying strategy behind them is unlikely to produce the same results.
Do not assume long-running ads are definitely working. Most of the time, longevity is a strong signal of performance. But some advertisers are not monitoring their accounts closely enough to pause underperforming ads. Use longevity as one signal among several, not as definitive proof.
Do not chase every competitor keyword. If a keyword is in a competitor’s campaign but not in yours, that does not automatically mean it should be. Evaluate each opportunity on its merits for your specific business, your offer, and your margins.
Do not obsess over competitors at the expense of your own strategy. Competitor research should inform your decisions, not drive them. The goal is to understand the market landscape and find opportunities, not to reactively mirror everything your competitors do.
Understanding what your competitors are saying in their ads is only half the picture. The other half is making sure your ads match what searchers are actually looking for. This short explains how search intent drives engagement and conversions.
How Competitor Research Fits Into Your Broader Google Ads Strategy
Competitor ad research is most valuable when it is part of a systematic approach to managing your Google Ads account, not a one-off exercise. The competitive landscape in paid search changes constantly. Competitors enter and exit. Offers change. Budgets shift. What worked three months ago may not be the winning strategy today.
A monthly check of the Transparency Center and Auction Insights, combined with regular review of your own campaign performance, gives you the intelligence to stay competitive without spending more than you need to.
