What your rivals' long-running ads tell you

Where to find them, legitimately

You do not need paid tools to start. Two public libraries do most of the work.

• [Meta Ad Library](https://www.facebook.com/ads/library/). A public, searchable library of ads running on Meta's apps, including Facebook and Instagram. Search for the advertiser, filter to active ads, and look at when each one started running.
• [Google Ads Transparency Center](https://adstransparency.google.com/). A searchable repository of advertisers and the ads they have served on Google platforms. You can filter by date and by the location an ad targeted, which matters if you sell only in the UK.

One rule matters more than any technique: never click a competitor's paid ads to see where they lead. Every click costs them money and muddies their data, and it is not how you would want to be treated. The libraries show you the creative and, often, the destination. Visit the landing page directly by typing its address if you need to see it.

What to record for each ad

A screenshot folder gets unreadable fast. A simple sheet with one row per ad works better. For each long-running ad, note:

• Start date as shown in the library, so you can sort by longevity.
• Hook: the first line or first frame. What problem, desire or claim does it lead with?
• Format: static image, carousel, short video, user-made style video, product catalogue.
• Offer: discount, free delivery, bundle, free sample, none at all.
• Angle: price, quality, speed, ethics, status, convenience, gifting.
• Proof: reviews, star ratings, press, guarantees, founder story.
• Landing page: home page, category, product page, or a dedicated campaign page.

Do this for each of the three rivals you compare yourself with most often. If you are unsure who they are, our guide on choosing which rivals to compare helps.

Reading the patterns

Once you have a few dozen rows, sort by start date and look at the oldest survivors together. You are looking for repetition, not for a single clever ad.

• If several long-running ads share a hook, that hook probably speaks to a real buying reason in your category.
• If a rival's long-runners carry no discount while their newer ads all do, they may be testing whether offers are needed at all, or they may have found that a full-price message holds up.
• If one format dominates the survivors, that format is likely cheap for them to produce and effective enough to keep. Ask whether you could make it too.
• If all the long-runners point to product pages rather than the home page, that tells you where they think the conversion happens.

Also look at what nobody says. If all three rivals lead with price and none leads with quality or after-sales care, that gap may be your opening. It may also mean the rivals tested those angles and dropped them. Treat it as a hypothesis to test, not a discovery.

How longevity can mislead you

Long-running does not always mean winning. Keep these caveats in front of you:

• Forgotten ads. Smaller advertisers sometimes leave an ad live because nobody has looked at the account. Low spend can keep a weak ad alive.
• Brand and retargeting ads. Some ads run for ages because they target people who already know the brand. They work, but for a different job than winning new customers.
• Budget is invisible. The libraries do not tell you how much was spent on a given ad, so you cannot rank ads by spend from public data alone.
• Seasonal reruns. An ad paused and restarted may show a fresh start date, hiding its real history.

The safest reading is the pattern across many survivors, from several rivals, checked against what you know of your own customers.

Turning it into your own brief

Do not copy. Copying a rival's ad invites comparison on their terms and, if you lift their words or imagery, trouble. Learn which buying reasons your market responds to, then say them in your voice with your proof.

A useful brief has three parts: the buying reason the long-runners share, the proof you can offer that they cannot, and two or three hooks to test against each other. Our recipe for turning longest-running ads into a creative brief walks through the sheet and the brief step by step, and the guide to reading rivals' ads goes deeper on format and angle.

Next step

Before you spend on new creative, check the pages your ads send people to. An Intel loop compares your store with up to three competitors you choose and quotes the evidence for every score. The competitor ad watch loop will keep this sheet for you; it is in build and not on sale. Until it ships, use the sheet above and size a test budget with the ad spend tool.
