See which ads competitors run, where they appear, and how long they have been live.
Ad intelligence software helps marketers inspect how competitors buy media, which messages they repeat and where campaigns appear. Coverage varies sharply by channel: some products specialize in Google Ads history, others in display and native placements, while broader digital-intelligence platforms track advertising across several ecosystems. Creative archives, landing-page visibility, publisher data and historical change tracking are the practical dividing lines.

For paid search research
#1 of 5 in Ad Intelligence
Semrush Advertising Research covers competitors in paid search. Marketers can inspect paid keywords, position changes, competing domains, ad copies and landing pages associated with search campaigns; its value is strongest when ad research needs to connect directly with keyword planning and organic-search work, because the same platform also exposes search visibility and competitor-domain information outside the paid channel.
For cross-channel ad context
#2 of 5 in Ad Intelligence
Similarweb's Ad Intelligence covers digital advertising across paid search, display and social environments, with views into creatives, publishers and distribution. It pays off when advertising needs to be read alongside broader website and market behavior, not as an isolated creative library. Teams can move from a competitor's media activity into traffic and audience research within the same data environment.
Google Ads history
#3 of 5 in Ad Intelligence
SpyFu lets marketers research the paid keywords a competitor has appeared on and inspect historical Google Ads activity. Its PPC competitor reports identify overlapping advertisers, while ad-history views show changes in copy and keyword use over time.
Digital market advertising
#4 of 5 in Ad Intelligence
Sensor Tower combines advertising intelligence with its wider digital-market datasets across apps, web and gaming. Its advertising research helps place competitor campaigns in the context of app publishers, digital audiences and category movement, extending beyond search keywords.
Display and native ads
#5 of 5 in Ad Intelligence
Adbeat specializes in competitive display and native advertising research. It surfaces competitor creatives, publishers and placements, landing pages and campaign activity, showing both ads and their distribution; this complements paid-search tools when the main question concerns banners, native units and sites carrying competitor campaigns.

Depending on the product, it can show paid keywords, ad copy or creatives, landing pages, publishers, placements and changes over time. Coverage is not identical across products, so a tool that is strong for Google Ads research may provide little help with native placements or mobile-focused advertising ecosystems.
Ad intelligence can show that an ad appeared and, in some products, how long or widely it was observed. That is not the same as seeing the advertiser's conversion data or profit. Use longevity and repeated deployment as clues, not as proof of campaign performance.
