Spy tools

A spy tool is a searchable archive of other people's ads. The vendor runs crawlers and devices that load publisher sites, subscribe to push feeds or trigger pop inventory in many countries, and records what shows up: the creative, the headline, the traffic network, the country, the first and last date it was seen, and where the click led. Following that redirect chain is what makes these tools useful to affiliates, because it exposes the prelander, the offer and often the affiliate network behind the campaign.

The practical question it answers is "what is already running, and for how long?" An ad that has been seen for weeks across several countries is probably profitable for somebody, because nobody keeps paying for a losing campaign. For a nutra buyer about to launch on native or push, that means seeing which offers, angles and advertorial formats are live in a given country before spending on a test.

What a spy tool does not show is anyone's actual numbers. Longevity and ad frequency are proxies for profitability, not proof.

Choose by the traffic you buy, then by data quality, then by price.

1. Coverage of your traffic type. Spy tools are usually sold per ad format. AdPlexity sells separate products for native, push, mobile, desktop and more; Anstrex sells native, push and pops as separate products too. Pay only for the format you actually buy. A native buyer gains nothing from a pop database.

2. Coverage of your networks and countries. Within a format, check whether the networks you buy from are crawled, and whether your target countries are. A tool strong on US and Western Europe native may be thin on the tier 2 and tier 3 countries where many nutra COD offers run. Ask for a demo or use the trial, and search for campaigns you already know exist in your geo. If the tool cannot find them, it will not find your competitors either.

3. Depth of the redirect chain. Seeing the creative is the easy part. What you need is the prelander and the landing page behind it, ideally with the affiliate network or offer identified. Check how often the tool gets past the tracker to the actual lander, and whether it lets you download that lander.

4. Freshness and history. A tool that updates daily and keeps long history lets you see how long an ad has run, which is the main signal. A stale database shows you last quarter's winners.

5. Search and filtering. Filter by network, country, affiliate network, keyword and date range. You will run the same searches every week, so saved searches and alerts save real time.

6. Price against how often you will use it. Spy tools are a fixed monthly cost with no link to your results. For a solo buyer testing one format, one product for a month or two during research is often enough; a team running several formats every week justifies more.

Treat what you find as a study of angle, structure and format, not as copy to lift: test the idea in your own geo, with your own prelander, before assuming it works.

Once coverage is settled, the differences that matter in daily use are:

• Lander access. Whether the tool follows the click to the real prelander and offer page, and how it deals with campaigns that show different content to crawlers. Some vendors advertise special handling for cloaked pages; that is exactly the behaviour ad platforms ban, and a copied lander may also carry the original affiliate's tracking.
• Longevity data. First seen, last seen, and how many days in between. This is the core signal.
• Affiliate network and offer detection. Filtering by network (for nutra, the big COD networks) turns a pile of creatives into a map of which offers are being pushed.
• Country depth. Number of ads per country in your geo, not the global total. Vendors quote headline counts; what matters is your slice.
• Export and team features. Favourites, shared folders, spreadsheet export.
• Update frequency. Daily or near-daily crawling for fast-moving formats like push.

Spy tools are flat monthly subscriptions per product, with no usage metering and, often, a discount for annual payment. As of September 2026, AdPlexity lists its native product at $249 a month and push at $149 a month, with about 20 percent off on yearly billing, and says it does not offer a free trial. Anstrex lists native at $79.99 a month and push and pops at $89.99 a month each.

Because each format is sold separately, the cost adds up quickly for a team that buys several formats. A buyer running native and push on AdPlexity would pay $398 a month on monthly billing. The honest way to budget is to subscribe for the research phase of a new geo or format, then cancel until the next one, unless you use the tool every week.
