Buying competitor keywords

How buying competitor keywords actually works - bidding on rival brand names, the legal lines, Google's ad-text rules, the cost reality, and when it's worth it.

Updated

Before you start

  • A live Google Ads account with at least $1k/mo in spend (lower budgets get crushed by smart-bidding auctions on brand terms)
  • A clear comparison page or competitor-alternative landing page (bidding on competitor brand without a landing page = expensive bounce)
  • Legal sign-off on bidding policy (some industries have stricter trademark enforcement)
  • Daily budget capacity for $10-50 CPCs on contested brand terms

The playbook

7 steps

0/7

  1. Pick the right competitor brands to attack

    Not every competitor brand is worth buying. The winners share three traits: (1) high brand search volume (~1k+ monthly searches in your geo), (2) the competitor's product is genuinely substitutable with yours, (3) your conversion rate from a comparison page is provably high. Bidding on a brand whose customers won't switch is expensive theater.

    Expected outcome

    A short list of 3-5 competitor brands worth bidding on, ranked by search volume × substitutability.

  2. Build a dedicated comparison landing page per brand

    Generic 'we're better than X' pages convert at ~1%. A dedicated /vs/competitor-name page with a side-by-side feature table, honest tradeoffs, and a tailored CTA converts at 4-8%. The landing page is the entire economic argument - it's why the campaign is worth running.

    TipInclude their logo on your comparison page (legally permitted under nominative fair use in the US). Removing it makes the page feel evasive.

    Expected outcome

    A live /vs/<brand> page per target competitor with side-by-side comparison and clear CTA.

  3. Create a separate campaign per competitor brand

    Don't lump competitor brand bids into a generic non-brand campaign. Separate campaigns let you control budget, write brand-specific ad copy, and measure ROAS per competitor. Use exact and phrase match - broad match on competitor brand terms burns budget on irrelevant queries.

    # Campaign structure:
# Campaign: COMP-<brandname>
# Ad group: <brandname> exact
#   Keywords: [competitor brand], ["competitor brand"]
# Ad group: <brandname> + intent
#   Keywords: [competitor brand alternative], [competitor brand vs]
# Daily budget: starts at $50-100, scale on ROAS

    Expected outcome

    One campaign per target competitor with exact/phrase match keywords and bespoke ad groups.

  4. Write Google-compliant ad copy

    Google's policy: you can bid on a competitor's trademark, but you cannot include their trademark in your ad text (in most regions). Your headline cannot say 'Better than HubSpot' - it can say 'A modern alternative for marketing teams'. The landing page can use their name freely; the ad copy cannot.

    Expected outcome

    Ad copy that bids on the brand keyword but avoids the trademark in headlines and descriptions.

  5. Set realistic max CPC and ROAS expectations

    Brand-name keywords are expensive. Expect CPCs 3-10x your non-brand average. Conversion rates from competitor brand traffic are often LOWER than non-brand (these searchers wanted the competitor, not you) but the LTV of a converted defector is often HIGHER (they explicitly chose you over an incumbent). Budget for 90 days before judging ROAS.

    Expected outcome

    A documented CPC ceiling and 90-day ROAS target per competitor campaign.

  6. Monitor for trademark complaints and escalation

    Two things happen when you start bidding on a competitor's brand: (1) Google may pause your ads if they file a trademark complaint, (2) they may retaliate by bidding on YOUR brand. Plan for both. Defensive brand-bidding (on your own brand) often needs to start the day you launch competitor brand-bidding.

    Expected outcome

    A monitoring routine that catches trademark suspensions and tracks defensive brand-bidding metrics.

  7. Scale the winners, kill the losers fast

    After 90 days, the per-competitor ROAS picture clarifies. Some competitor brand campaigns will print money (10x+ ROAS - their customers genuinely wanted to leave). Others will burn budget (sub-1x ROAS - their customers are loyal). Kill the losers within 90 days; scale the winners aggressively.

    Expected outcome

    A pruned campaign portfolio focused on the 1-2 competitor brands that actually convert.

Pitfalls

What goes wrong

  • Bidding on competitor brands without a comparison page

    Sending competitor-brand traffic to your homepage is the single biggest waste in this playbook. The visitor searched for a specific product; landing on your generic homepage gives them no reason to switch. Comparison pages are non-negotiable.

  • Putting competitor trademarks in ad headlines

    Google will suspend the ad and, if you keep doing it, the entire account. Use the competitor name on the landing page freely; keep it out of the ad text.

  • Forgetting to defend your own brand

    Buying competitor keywords without defending your own brand is asymmetric warfare in their favor. The week you launch competitor bidding, also turn on a defensive brand campaign on your own name.

  • Treating brand-bid ROAS like non-brand ROAS

    Brand-bid campaigns have different economics: lower conversion rate, higher LTV per converted user, longer payback window. If you judge them by the same ROAS bar as non-brand campaigns, you'll kill winners before they prove out.

  • Ignoring auction-price escalation

    When two competitors both bid on each other's brand names, the auction prices spiral. Within 6-12 months a $2 CPC can become $20. Have a CPC ceiling and walk away when it's breached - or negotiate a mutual ceasefire (it happens more than you'd think).

Limits

When this playbook won't work

  • Your competitor has stronger brand affinity than your product can disrupt (Apple bidding on Samsung doesn't convert defectors)
  • Your industry is regulated and trademark enforcement is strict (pharma, legal, financial services in some jurisdictions)
  • Your competitor's brand search volume is low (<500/mo in your geo) - not enough traffic to justify the campaign overhead
  • You don't have a comparison page and aren't willing to build one - this playbook fails without it
  • Your sales cycle is 6+ months (B2B enterprise) - attribution back to a brand-bid click is too fuzzy to optimize against

The legal reality of bidding on competitor brand names

Bidding on competitor trademarks is legal in the United States. The 2009 Rosetta Stone v. Google and 2011 Network Automation cases established that purchasing a competitor's trademark as a keyword is not infringement, provided your ad doesn't create consumer confusion. The EU has more variable rules - some jurisdictions are stricter on what the ad copy can say.

Google's policy enforcement is separate from legal status. Even where it's legal, Google may restrict your ad text if a trademark holder files a complaint. The most common restriction: you cannot use the competitor's trademark in the headline or description. The landing page is unaffected.

Nominative fair use - the legal doctrine that lets you refer to a competitor by name on your own website (e.g. 'Shuttergen vs Arcads') - is broadly recognized in the US. Your comparison page can legally use the competitor's name, logo, and product references provided you're truthful and don't imply endorsement.

When in doubt, ask legal. This playbook is general guidance, not legal advice. If your industry has trademark-litigious incumbents, get sign-off before launching.

The auction-cost spiral problem

When you bid on Competitor X's brand, Competitor X is told (via their own Auction Insights) that you're showing on their brand terms. Their natural response is to bid harder on their own brand to defend, AND to start bidding on YOUR brand in retaliation. Within 3-6 months, both brands' CPCs on each other's terms can quadruple.

The escalation has a ceiling - your unit economics. When the blended CAC from brand-bidding exceeds your customer LTV, the campaign stops paying. Some categories (CRM, project management, marketing automation) saw $50+ CPCs on competitor brand terms by 2026 - economically untenable except for the largest players.

Mutual ceasefires happen quietly. When two competitors both notice CPCs spiraling without share-shift, the strategy teams sometimes agree to pull back on each other's brand terms. It's not collusion; it's recognizing that the auction is destroying value for both sides without creating share-shift. If you're seeing CPC escalation without conversion-rate gains, consider whether a backchannel conversation makes sense.

FAQ

Frequently asked

Is it legal to bid on competitor keywords?
In the US, yes - bidding on a competitor's trademark as a keyword is legal under the Rosetta Stone v. Google precedent. EU rules vary by jurisdiction. Google may restrict your ad text if a trademark complaint is filed, but the bidding itself is permitted.
Can I use my competitor's name in the ad copy?
Generally no - Google's trademark policy lets the trademark holder restrict use of their name in your ad headline and description. You can use it freely on your landing page under nominative fair use, just not in the ad text itself.
How much does it cost to bid on competitor brand keywords?
Typically 3-10x your non-brand CPCs. Categories with active brand-bidding wars can hit $20-50 CPCs on contested brand terms. Budget for $50-100/day per competitor at minimum, and expect 90 days before ROAS clarifies.
Will my competitor retaliate if I bid on their brand?
Usually yes. Within 30-60 days you should expect them to start bidding on your brand. Launch defensive brand campaigns on your own name the same week you launch competitor bidding.
What's the conversion rate on competitor brand traffic?
Lower than non-brand traffic typically - these searchers wanted the competitor, not you. But LTV per converted user is often higher because they explicitly switched. Comparison landing pages are essential for converting at meaningful rates (4-8% vs 1% on a generic homepage).
Should I bid on every competitor's brand name?
No. Pick 3-5 competitors with high brand search volume AND high substitutability with your product. Bidding on every competitor in the category dilutes budget and creates retaliation surface without proportional return.
How do I know if buying competitor keywords is working?
Measure per-campaign ROAS over 90 days, not 30. Track blended CAC including the lower conversion rate on brand traffic. Compare LTV of converted defectors against your normal customer base. If LTV × conversion rate > CPC × clicks-to-convert, it's working.
