PPC Brand Defense
Quick Answer
If a competitor is bidding on your brand keywords in Google Ads, your five-step response is: detect them in AdSpyder’s Google Ads Spy, classify the bidder type, decide your counter-strategy, monitor ongoing activity, and measure impression-share recovery. In India, the May 2026 Delhi High Court ruling in Hindware vs Google changed this permanently: even invisible backend keyword use is now confirmed trademark infringement under the Trade Marks Act, 1999, and Google has been stripped of its safe harbour defence. Every registered Indian trademark holder now has clear legal grounds to act.
You spend months building demand around your brand name. Customers search for you specifically — that is your highest-intent traffic. Then a competitor buys your brand name as a Google Ads keyword, and their sponsored result appears above yours.
Most brands discover this months after it starts. By then the traffic has leaked, revenue has gone elsewhere, and the competitor’s Quality Score on your brand keyword has grown stronger.
In May 2026, the Delhi High Court changed the stakes permanently for Indian brands. What was a grey-area PPC tactic is now a legally established act of trademark infringement — and liability applies to the competitor doing the bidding, not just the platform. This guide gives you the complete action plan: how to detect it, how to classify who is doing it and why, how to respond based on attacker type, and how to use the Hindware ruling if you are an Indian brand with a registered trademark. Every step is backed by real data from AdSpyder’s ad intelligence platform.

The Ruling That Changed Brand Bidding Law in India: Hindware vs Google, May 2026
On May 22, 2026, Justice Mini Pushkarna of the Delhi High Court delivered a 163-page judgment in Hindware Ltd. v. Google LLC [CS(COMM) 591/2017] that permanently restrained Google LLC and Google India from using “HINDWARE” or any deceptively similar variation as an advertising keyword — and ordered Google to pay ₹30 lakh in nominal damages.
The case began in 2013 when Hindware — a coined, registered trademark with 40% market share in Indian sanitaryware — discovered that competitors Cera Sanitaryware and Grohe India had bought its trademark as a Google Ads keyword. Competitor sponsored ads appeared above Hindware’s organic listing. Cera and Grohe eventually settled. Google alone contested the case for nine years, arguing it was a neutral intermediary. The court disagreed on every substantive ground.
Four findings every brand manager needs to know:
1. Invisible keyword use equals trademark infringement
The keyword trigger never appears in the visible ad. The court held this does not matter: backend keyword use qualifies as trademark use under Section 29(6) of the Trade Marks Act, 1999. A competitor does not need to write your brand name in their ad headline for infringement to exist. The invisible traffic diversion is the infringement.
2. Google lost its safe harbour protection
Google argued Section 79 of the IT Act shields it as an intermediary. The court stripped that protection on two grounds: Google’s Keyword Planner actively suggests trademarked terms to advertisers during campaign setup, and Google earns revenue from every click on trademarked keywords. That is active participation, not passive hosting.
3. The advertiser is liable too — not just the platform
The ruling is not limited to platforms. The competitor who placed the keyword bid also infringed Hindware’s trademark. If a rival is bidding on your registered brand keyword in India, they face direct legal liability — not just a Google policy complaint that the platform can ignore.
4. The precedent is binding and immediate
This Delhi High Court ruling sets binding precedent within its jurisdiction and is highly persuasive across other Indian High Courts. Prominent founders including Nithin Kamath of Zerodha and Anupam Mittal of Shaadi.com have publicly stated this ruling opens legal recourse they had been denied for years.

Outside India
In most other jurisdictions, Google permits brand keyword bidding at the keyword level — using a competitor’s trademark as a bid trigger is generally allowed. Using the trademark visibly inside ad copy is where restrictions apply. The Hindware ruling is specific to India under the Trade Marks Act, 1999. The strategic advice in this blog applies globally; the legal escalation options apply to Indian registered trademark holders specifically.
How Widespread Is Competitor Brand Bidding? The Data
Most PPC managers assume brand bidding is rare — something that happens to Netflix, not to them. AdSpyder analyzed 8.5 million Google Search ads across 25 of the world’s most-searched brand keyword auctions. One in eight of those ads came from a different advertiser, not the brand being searched.

The 5 Brand Hijacking Patterns in Paid Search — With Ad Counts
Not all brand hijacking looks the same. AdSpyder’s analysis of 164M+ Google Search ads reveals five distinct attack patterns. Each needs a different detection method and a different response.
Direct Competitor Conquesting
What it looks like: A competitor’s ad appears on your brand keyword — “Switch from [Your Brand]” or “[Your Brand] Alternative — Better Pricing”. Across 25 of the world’s biggest brand-keyword auctions, 13.1% of all ads come from non-brand advertisers — roughly 912,951 ads in AdSpyder’s sample.
Detection: Search your exact brand name in AdSpyder’s Google Ads Spy. Any advertiser domain that is not yours is a conquesting candidate.
“Official Site” Impersonation
What it looks like: An ad carries “Official Site” or “Official Store” in the headline but the destination domain is not the brand’s real domain. Common in finance, software licensing, and consumer electronics. 3.39 million Google Search ads use “Official Site” or “Official Store” phrasing — a further 5.27 million use “official” in any context. That volume far exceeds the number of genuinely official brand presences; the gap is where impostor activity lives.
Detection: Search “[your brand] official site” in AdSpyder. Any ad whose destination domain is not yours is an immediate red flag — and under the Hindware ruling, grounds for legal action in India.
“Alternative to” and “Better Than” Positioning
What it looks like: Competitors run ads explicitly framing themselves as the better substitute — “Alternative to [Brand]”, “[Brand] vs Us”, “Cheaper than [Brand] for Teams”. 393,000+ Google Search ads use “alternative to”, “alternatives to”, or “better than” phrasing. Adobe faces this from Filmora; Shopify from Ecwid; Grammarly from Outwrite.
Detection: Search “alternative to [your brand]” and “better than [your brand]” in AdSpyder. These ads target users who already know you and are considering switching.
Coupon / Affiliate / Discount Redirect Hijacking
What it looks like: Coupon aggregators, voucher sites, and unauthorized affiliates bid on your brand keyword with copy like “[Brand] Promo Code” or “[Brand] 50% Off”. They capture the click, drop the user on a page with competitor affiliate links, and earn commission regardless of where the user converts. 475,331 Google Search ads use “compare prices” phrasing. This is particularly insidious because the coupon site often holds a legitimate affiliate contract with you — making it a compliance problem as much as a competitive one.
Detection: Search “[brand] coupon”, “[brand] promo code”, “[brand] discount” in AdSpyder. Compare destination domains to your affiliate programme’s approved list.
Review and Comparison Site Bidding
What it looks like: Review platforms and comparison engines bid on “[Brand] reviews”, “[Brand] vs Competitor”, or “[Brand] pricing” to capture research-stage traffic. Their pages typically carry paid placements for competing products. 3.33 million Google Search ads use “review” or “reviews” phrasing — 2.02% of the entire 164M+ archive. This is the highest-volume hijacking pattern by ad count because it spans every category.
Detection: Search “[brand] reviews” and “[brand] vs” in AdSpyder. Check whether the review site lists you fairly or exclusively promotes competitors.

Your Industry Determines Your Hijacking Risk Level
Brand hijacking is not evenly distributed. AdSpyder analyzed 25 of the world’s largest brand-keyword auctions — 8.5 million ads — and the risk pattern is clear: your industry archetype determines your exposure more than how aggressively you currently defend.
| Industry | Sample Brands | Non-Brand Ad Share | Primary Hijacker Type |
|---|---|---|---|
| Streaming | Netflix, Disney+ | Up to 72% | VPN providers, rival streaming services |
| Travel / OTA | Booking.com, MakeMyTrip | Up to 70% | Meta-search engines, regional OTAs |
| Electronics | Samsung | 54% | Resellers, price-comparison sites |
| Apparel / Footwear | Nike, ASOS, SHEIN | 5% – 48% | Multi-brand retailers, competitor shops |
| Design / Productivity SaaS | Adobe, Shopify, Canva, Grammarly | 4% – 15% | “Alternative to” competitor ads |
| Indian eCommerce | Flipkart, Myntra | ~4% | Coupon sites, limited direct competition |
| Marketplaces | Mercado Libre, Agoda, eBay | 0% – 3.4% | Near-zero — platform dominance as natural defense |

What this means practically
If you are in SaaS, travel, streaming, or consumer electronics, brand hijacking is already happening at scale in your category. Waiting to discover it through a sudden impression-share drop or a customer complaint means it has been going on for months. Even lower-risk categories like Indian eCommerce still face coupon-site bidding. The risk is lower, not zero.
The 5-Step Brand Keyword Defense Action Plan
Work through these in order. Do not jump to counter-bidding before the classification step — the right response depends entirely on who is bidding and why.
1
DETECT — Find Out Who Is Bidding on Your Brand
You cannot defend what you cannot see. Start with a systematic detection pass, not a one-time manual Google search in Incognito.
Why a manual Google search is not enough: results vary by location, device, time of day, search history, and auction conditions. A competitor bidding in Mumbai may not appear in a search from Delhi. A campaign running on mobile may not show on desktop. You only see a single slice of a dynamic auction.
With AdSpyder: Go to AdSpyder’s Google Ads Spy and search your exact brand name. The results show every advertiser whose ads appeared on that keyword across 164M+ indexed ads. You see:
- The advertiser’s domain
- Full ad headline and body copy
- The destination landing page URL
- First-seen and last-seen dates
- Country and market the ad appeared in
- Position in the SERP
Extend the search to your brand + “review”, brand + “pricing”, brand + “alternatives”, brand + “vs”, brand + “coupon” to catch all five attack patterns.
Evidence tip: Document everything before moving to Step 3. Screenshot or export the list of advertiser domains, ad copy, and first-seen dates. Under the Hindware ruling, first-seen and last-seen dates from AdSpyder constitute part of the evidence package for an Indian trademark complaint or legal filing.
2
CLASSIFY — Not Every Brand Bidder Needs a Cease-and-Desist
The right response to a coupon site is completely different from the right response to a direct competitor. Run each flagged domain through AdSpyder’s Domain Analysis to see their full ad portfolio, then classify each one:
| Bidder Type | How to Identify It | Urgency |
|---|---|---|
| Impostor / look-alike | Uses “Official Site”, cloned landing page, suspicious domain | CRITICAL |
| Direct competitor | Same industry, “alternative to” or “vs” copy, links to their product page | HIGH |
| Unauthorized affiliate | Coupon/deal site not in your programme, or affiliate violating brand-bidding policy | HIGH |
| Authorized affiliate violating policy | In your programme — but their agreement prohibits brand keyword bidding | MEDIUM |
| Comparison / review site | G2, Capterra, editorial site with your brand in title | MEDIUM |
| Marketplace reseller | Amazon, Flipkart — sends traffic to a listing page for your actual product | LOW |
3
DECIDE — Match Your Response to the Bidder Type
🚨 Impostor — Act Within 24 Hours
- File a Google Ads trademark complaint through Google’s Ads policy help pages. Attach the AdSpyder export as your evidence file.
- In India: send a legal notice simultaneously to both the advertiser and Google under the Hindware vs Google precedent. Invisible keyword use is confirmed infringement — you do not need the brand in the visible ad to act.
- If the landing page clones yours, file a DMCA takedown with their hosting provider and a domain abuse report with the registrar.
⚔️ Direct Competitor
- Run or strengthen your own brand campaign with exact-match brand keywords. You will almost always have a higher Quality Score for your own brand name — meaning you pay less while holding top position.
- Sharpen your brand ad copy. Lead with a specific offer, your USP, and a direct CTA. A bland “Official Site” headline can lose to a well-written competitor ad even at a lower Quality Score.
- Consider counter-bidding on their brand keyword. This creates a mutually-assured-bidding dynamic — many competitors back off when they see their own name being targeted in return.
- In India: if the competitor uses your registered trademark as their keyword, the Hindware ruling gives you direct legal grounds to file a trademark complaint and send a legal notice — without needing your name to appear visibly in their ad copy.
🔗 Unauthorized Affiliate
- Send a written cease-and-desist to the site owner. State clearly that brand keyword bidding is not permitted without written authorization.
- File a Google Ads trademark complaint if their ad copy uses your brand name visibly.
- If they are earning commissions through a network you are on, flag the affiliate manager for policy violation and deny commission on disputed transactions.
📋 Authorized Affiliate Violating Brand Bidding Policy
- Check your affiliate agreement. Most explicitly prohibit brand keyword bidding. A direct reminder is usually enough for established affiliates who want to keep the relationship.
- If they persist, suspend or terminate their affiliate account.
⭐ Comparison / Review Sites
- Engage editorially: claim your listing on each platform, respond to reviews, push for a stronger position in their rankings.
- Use AdSpyder’s Landing Page Analysis to see exactly where they send your brand searchers. If they consistently push competitors over you, treat them as a medium-urgency case and maintain 95%+ brand impression share so your ad always appears above theirs.
🛒 Legitimate Marketplace Reseller
- Generally: tolerate it. The marketplace is selling your product — the conversion still reaches you.
- If their bid pushes you below position 1, increase your own brand campaign bids. You should win on Quality Score alone.
4
MONITOR — Set Up Ongoing Brand Keyword Surveillance
A one-time audit is not a defense. Competitors start and stop brand bidding campaigns constantly. New entrants appear. Old ones return after a cease-and-desist lapses. Brand keyword monitoring needs to be a repeating workflow.
With AdSpyder: Add each identified violator domain to a Competitor Tracking project. There are currently 8,663 active tracking projects monitoring 3,687 competitor domains across AdSpyder (AdSpyder platform data, May 2026). When you run subsequent Ad Library searches for your brand keyword, you will see whether those domains are still active and whether new ads have appeared.
Cross-platform: Brand hijacking rarely stays on one platform. Run the same brand-name search on Meta, Bing, YouTube, and LinkedIn using AdSpyder’s respective ad spy tools. The same competitor often runs parallel campaigns across platforms.
Coming soon: Brand Keyword Alerts
AdSpyder is building a real-time Brand Keyword Alert feature that will notify you the moment a new competitor ad appears on your brand keyword — across platforms. Instead of a weekly scan, you get notified the day it happens. This closes the detection gap that causes most brands to discover brand bidding only after significant traffic has already leaked.
5
MEASURE — Track Recovery in Google Ads
Once you have acted on Steps 1–4, confirm that your defense is working by tracking these metrics inside your Google Ads account:
| Metric | Where to Find It | Target |
|---|---|---|
| Brand Impression Share | Campaigns → Competitive Metrics | 95%+ |
| Absolute Top Impression Share | Campaigns → Competitive Metrics | 90%+ on exact brand match |
| Branded CPC trend | Keyword report — filter brand terms | Stabilises or drops as competition reduces |
| Auction Insights — Overlap Rate | Campaign → Auction Insights | Decreases for known violators after enforcement |
Note: AdSpyder does not connect to your Google Ads account and does not display CPC or impression share. The measurement step lives entirely in your Google Ads UI. AdSpyder’s role is in Steps 1, 2, and 4 — competitive intelligence, classification data, and ongoing monitoring. Both tools are needed for the complete picture.
Taking Legal Action in India: What the Hindware Ruling Enables
Before May 22, 2026, an Indian brand facing competitor brand keyword bidding had two realistic options: file a Google Ads trademark complaint (often slow and uncertain), or pursue litigation with no guarantee the court would find invisible keyword use to constitute infringement. Both options changed with the ruling.
| Action | Before Hindware Ruling | After Hindware Ruling |
|---|---|---|
| Google Ads complaint | Uncertain; Google’s India policy did not investigate invisible keyword-use complaints | Google faces legal exposure for non-action; complaint carries significantly greater leverage |
| C&D to competitor | Grey area — advertiser could argue invisible keyword use is not trademark infringement | Invisible keyword use is confirmed infringement; C&D carries binding legal weight |
| Court injunction | Contested legal basis; typically multi-year proceedings | Binding precedent; interim injunction applications on much stronger footing |
| Platform demand letter | Google could invoke Section 79 IT Act safe harbour to dismiss liability | Safe harbour stripped where platform actively suggests trademarked keywords |
Important caveat
The Hindware ruling is a single-judge Delhi High Court order. It sets binding precedent within its jurisdiction and is highly persuasive in other Indian High Courts — but it is not a Supreme Court ruling and may be challenged on appeal. Consult a qualified IP attorney before formal legal action. This blog does not constitute legal advice.
What the ruling confirms beyond litigation: if you are an Indian brand with a registered trademark and a competitor is bidding on your brand keyword in Google Ads, you now have a documented legal basis to demand that Google restrict those bids. That demand carries consequences the platform can no longer dismiss as it previously could.
