Anstrex for Native Ads: Spy on Profitable Taboola & Outbrain (2026)

When I launch a new offer on Meta, I open the Facebook Ad Library, type a keyword, and see every competitor running it. TikTok gives me almost the same thing, even sorted by highest CTR over the last seven days. Native advertising gives me none of that. Taboola, Outbrain, Yahoo Gemini, and RevContent run across the open web, not inside one company's walled garden, so there is no button that shows you who is winning.

That gap is exactly why a spy tool earns its keep. In my agency we run Anstrex Native, which pulls ads from 27 native networks into one searchable index for about $70 a month. This is the workflow I use to find competitor ads that are already profitable, and the filters that keep me from wasting time on the 95% that aren't.

Why native advertising has no free ad library

Native ads are a category, not a single platform. "Native" describes ad placements that match the look of editorial content, and dozens of separate companies sell that inventory: Taboola, Outbrain, Yahoo Native, MGID, Newsbreak, Mediago, RevContent, and more.

Marcel Sattler, founder of native-advertising.net, has deployed more than $100M across Taboola, Outbrain, Newsbreak, MGID, Yahoo Native, Mediago, and RevContent since 2015, and the single biggest blind spot he hit in the early years was creative. On Meta you copy a winning angle in five minutes. On native there is no shared library, because no single company owns the inventory the way Facebook owns its own feed.

So when you launch a fresh offer on Taboola, you are guessing at headlines, images, and advertorial structure unless you pay for a third-party tool that crawls all the networks at once. That tool is the substitute for the ad library Taboola and Outbrain still don't offer.

Anstrex Native vs Push: pick the right product first

Before you pay for anything, know that Anstrex sells more than one product, and buying the wrong one is a $70/month mistake. There is Anstrex Native, Anstrex Push, and a dropshipping product, and they index completely different traffic.

For media buyers running Taboola, Outbrain, and the rest, the only one that matters is Anstrex Native. Anstrex Push covers push notification ads, and the dropshipping tool covers pop and product feeds. If you sign up and search Taboola creatives inside the Push product, you'll find nothing useful.

The pricing starts around $70 a month. That is steep when you're just starting and haven't spent a dollar on traffic yet. But once you're trying to scale native, one competitor advertorial you can model is worth far more than the subscription. If you want help deciding whether you're even at the stage to pay for it, book a strategy call before you subscribe.

The first search is useless. The filters are everything

When you type a broad keyword like "skin" into Anstrex, you get a wall of ads. You'll see the image, the headline, the brand, the ad network, the country it runs in, and sometimes the tracking technology behind it. It looks impressive and it is almost worthless, because most of those ads are losers that nobody paused yet.

The raw feed is noise. The value comes from filtering it down to ads that have proven themselves with real money. Here are the two filters I set on every single search.

Filter 1: ad age of 10+ days (or 3 weeks)

The most powerful signal in the tool is how long an ad has been running. Anstrex shows you the date an ad was first seen and the date it was last seen, and that spread tells you whether someone is making money.

No sane media buyer keeps an unprofitable ad live for more than three weeks. So I set a minimum age filter:

• 10+ days running is my baseline for "worth a look."
• 3+ weeks running is near-certain proof the ad is profitable.
• 1 day old gets ignored. A brand-new ad is an untested guess, and copying a guess just imports someone else's risk.

This single filter does most of the work. An ad that survived 21 days on Taboola passed a test you'd otherwise have to pay to run yourself.

Filter 2: Ad Strength score

Anstrex also assigns an internal "Ad Strength" value to every creative. The higher the number, the stronger the tool rates the ad based on its own signals. I use it as a secondary sort after the age filter, not as a replacement for it. Age tells you the ad is profitable; Ad Strength helps you rank which profitable ads to study first.

What Anstrex does not give you is spend or revenue. Unlike TikTok's library, which sorts by highest CTR, six-second view rate, or reach over 7 and 30 days, no native spy tool shows you the money behind an ad. That's why ad age is the closest thing to a profitability proxy you'll get.

Rip the whole funnel, not just the ad

The ad itself is the least valuable part of what Anstrex hands you. The ad gets you a click. The advertorial and landing page get you the sale, and that's where the real intelligence lives.

When you find an ad that passed the 10-day filter, click through to the page. On a clip ad I pulled, the destination was a short branded advertorial with an embedded video, and after the video the visitor could buy the product. The ad had run from April 1st to May 6th, which is a 35-day lifespan and a strong profitability signal on its own.

You can rip the whole thing: the headline, the advertorial structure, the offer page layout. I'm not giving legal advice, and you have to confirm any creative element is allowed in your country, but as a best practice you study the parts that are clearly working and rebuild them in your own voice. A 35-day-old advertorial is a battle-tested template, not a blank page. If you're modeling these for an ecommerce offer, our ecommerce play starts from exactly this kind of teardown.

Search by competitor, not just by keyword

Keyword search is the obvious entry point, but the highest-leverage move in Anstrex is searching by competitor. The tool lets you search by creative text, translated text, landing page URL, domain, and publisher domain, among many other fields.

In my agency, when we already know who our competitors are, we don't fish with broad keywords. We search their brand name and their domains directly to pull every ad and advertorial they're running on native. That tells us their exact angles, which networks they favor, and how long each ad has survived.

A few search angles that consistently pay off:

1. Competitor brand name to reverse-engineer a known player's entire native funnel.
2. Landing page or domain to map every offer running off a single advertiser's site.
3. Publisher domain to see which placements competitors trust enough to keep buying.
4. Translated text to mine winning angles from foreign-language markets you can adapt.

I ran a German-language search to test this and pulled a five-day-old advertorial with a shocking headline. Five days is borderline, so I'd watch it rather than copy it, but the German example proves the same teardown works across Taboola, Outbrain, and every other network in any market the tool indexes.

Skip the arbitrage ads (unless that's your game)

One warning that saves a lot of wasted time: a large share of what you'll see in Anstrex is search arbitrage and AdSense arbitrage, not real product offers. Those ads often look scammy on purpose, and they don't run on CPA or KPI-based models, so they're useless as a model for a DTC or affiliate offer.

If you're running a real product or a lead-gen campaign, learn to spot and ignore the arbitrage ads fast. They're optimizing for ad-network revenue, not for a sale, so their headlines and pages follow rules that won't transfer to your funnel. Filtering them out is part of why the raw feed feels so noisy before you set your filters.

Where to go from here

A spy tool tells you what's working. It doesn't build your funnel, write your advertorial, or manage your bids across 27 networks, and a $70/month subscription is the cheapest part of scaling native. The expensive part is turning those competitor teardowns into campaigns that actually clear profit.

That's the part we run for clients every day across Taboola, Outbrain, MGID, Yahoo Native, and the rest.
