How to reverse-engineer your competitor's paid ad strategy

Executive overview

Most advertisers launch campaigns based on guesswork. Your competitors have already run the experiments — and lost the money doing it. Tools like SEMrush and AdClarity expose what they spent, where they spent it, which ads they kept running, and which they killed.

Use competitor ad data to inherit their wins and skip their mistakes before your campaign goes live.

Reading search ad data in SEMrush

• Enter a competitor domain to see keywords, monthly ad spend, and estimated traffic
• Figures are estimates, but reliable enough for benchmarking and directional decisions
• View spend trends over time to spot acceleration or retreat from a channel
• Hover the ad icon on any keyword to see the exact ad copy being run
• Check the destination URL to study the landing page structure and offer

What competitor search ads reveal

• Branded keywords show what a competitor defends and at what CPC premium
• High-spend, competitive terms (e.g. "CRM" at $35 CPC) signal strategic priorities
• Bidding on competitor brand names is a common acquisition tactic worth noting
• Low-CPC, tangentially related terms (e.g. "email signature generator") signal top-of-funnel acquisition plays targeting future buyers
• Landing page analysis exposes offer type, CTA, and funnel design — a closed page with a single CTA reveals conversion strategy

Using AdClarity for display and social ads

• AdClarity (separate subscription from SEMrush) shows display, social, and video ads with spend and impression data
• Top-level stats include total impressions, estimated spend, budget split across channels, and ad-buying method (programmatic vs. direct)
• The advertiser expenditure trends chart shows spend by channel over time — the most actionable view
• A sharp drop in display spend signals a channel or creative approach that likely failed
• Consistent social spend signals a channel that's working; low video spend signals it hasn't been prioritised or tested and cut

What Meta's ad library misses

• Meta's ad library shows only live ads, with no spend or impression data
• AdClarity shows historical ads, spend per ad, impressions, run duration, and channel placement
• Knowing an ad ran for five months at $48k versus twelve months at $178k tells you which creative to take influence from
• Campaign reports inside AdClarity group all creative from a single campaign, giving a full picture of messaging and format choices

Patterns to look for across competitor ads

• Consistent visual or messaging style over time suggests a winning formula worth studying
• Channels with sustained spend are proven; channels that spike and drop are likely tests that failed
• Repeated offers or CTAs across landing pages confirm what's converting
• UGC-style creative appearing repeatedly on TikTok or social signals format preference and audience fit
