The ads, advertisers and stores behind every tool, in one archive
Each tool here answers one question about one ad, one brand or one number.
Spytrend is an ad intelligence platform for Facebook and TikTok advertising: a full five-year archive of ads, AI-classified into 33 business categories, with every advertiser assembled into a single card — all ads, pages, domains and countries in one place.
- From a lookup to the advertiser. The advertiser lookups each return one slice of an advertiser. In Spytrend those slices sit together on its card: every ad with its launch date, days running and countries, beside its pages and domains.
- From a target number to the ads that stayed live. A calculator tells you the ROAS or CPA a campaign has to beat. In Spytrend you can filter a category to the ads that have run for months, the ones their advertisers kept paying for.
- From one creator to the ads in its niche. The creator checks score one account against accounts of its size. In Spytrend you can search the brands in that niche and see the ads they keep paying for.
- From a store to the ads that point at it. The Shopify detectors read the theme and apps behind a store. In Spytrend you can search that store’s domain and see the ads that link to it, with how long each one has run.
- From one transcript to any video ad. On paid plans, any video ad in Spytrend can be transcribed, translated or voiced in one click.
- From a draft to the copy that keeps running. The writing tools help you draft and fit ad copy. In Spytrend you can read the copy of ads that have run for months in your category, the words their advertisers kept paying for.
Spytrend adds 10 million new ads a day and records how long each one ran.
Why the archive, not one lookup
A lookup gives you a single data point: the age of one ad, the countries of one brand, one ratio from your own account. Deciding what to run next takes the pattern across a whole category, meaning which advertisers keep paying for which angles and for how long, and that pattern only shows up when thousands of ads sit side by side.
How to start
A free Spytrend account opens the ad library; paid plans add fresh ads and every filter. A good first search is a brand or a domain you already checked with one of the tools above.
FAQ
A tool settles one question. The archive takes the next one.
In Spytrend, search a brand or a domain and read every ad behind it, with how long each one has run and who pays for it.
