What Should You Actually Look At When “Spying” on a Competitor’s Ads?
“Spying” sounds more dramatic than it actually is, this is entirely legal, public, and genuinely useful competitive research, not anything covert. Knowing what to actually look at when spying on a competitor’s ads turns a vague curiosity into a genuinely useful research process.
Where to Actually Find Competitor Ads, for Free
Before looking at anything specific, start with the source, official ad libraries that publicly show any advertiser’s currently running ads.
- Meta Ad Library shows every ad currently running across Facebook and Instagram for any advertiser, searchable by business name
- Google’s Ads Transparency Center shows ads a given advertiser is currently running across Google’s network
- Both are free, official, and require no special tools or subscriptions to use
Look at Which Ads Have Been Running the Longest
This single signal tells you more than almost anything else available for free.
- An ad still active after weeks or months is very likely a genuine performer, businesses do not keep paying for ads that lose money
- A pattern of short-lived ads that get quickly replaced suggests those specific creatives or offers were not working
- This “still running equals probably working” logic is one of the most reliable free signals in competitor ad research
Study the Actual Hook and Opening Line
The first few words of an ad’s copy, or the first seconds of a video ad, carry disproportionate weight in whether anyone engages at all.
- What specific problem or emotion does the opening line address
- Is the hook built around urgency, curiosity, a specific number, or a direct benefit statement
- Compare this against your own current ad copy’s opening line honestly
Examine the Offer, Not Just the Creative
The visual and copy matter, but the actual offer underneath is often the real story.
- What specific discount, guarantee or incentive is being presented
- Is pricing shown directly, or is the ad designed purely to drive a click for more information
- A consistently repeated offer across multiple ads suggests it is the one converting best
Check the Landing Page an Ad Actually Leads To
Clicking through to see where an ad sends traffic reveals whether the messaging carries through consistently.
- Does the landing page match the ad’s specific promise, or does it feel disconnected
- What is the actual call to action on that page
- Note load speed and mobile experience, since this affects conversion regardless of how strong the ad itself is
What This Research Should Actually Change
The point of this exercise is not copying a competitor outright, it is understanding what a market is currently responding to and identifying a genuine gap you can fill better, a stronger offer, more specific proof, or a hook addressing something competitors are missing entirely.
A Practical Weekly Habit Worth Building
- Check your two or three closest competitors’ ad libraries once a week
- Note any new ad and any ad still running from your last check
- Compare against your own current campaigns honestly, not defensively
Where This Fits Into Broader Ad Strategy
This kind of ongoing competitive awareness is a genuinely useful input into performance marketing strategy, it should inform, not replace, your own testing and the conversion tracking work that actually tells you what is working for your specific business.
FAQs
Is it legal to look at a competitor’s running ads?
Yes, completely. Meta Ad Library and Google’s Ads Transparency Center are official, public tools showing any advertiser’s currently active ads.
How do I know if a competitor’s ad is actually working?
An ad that has been running for weeks or months without being replaced is a strong signal it is performing, since businesses generally stop paying for ads that lose money.
Should I copy a competitor’s ad if it’s clearly working well?
No, direct copying rarely works and can raise ethical and legal concerns. Use the research to understand what resonates, then build a genuinely differentiated offer or hook of your own.
