Competitor keyword bidding in Google Ads: when it works and when it wastes money
Bidding on competitor brand names in Google Ads is legal and common in B2B SaaS. Done correctly, it captures prospects actively evaluating alternatives. Done wrong, it's expensive clicks from users who already chose the competitor and aren't switching. Here's the framework for when competitor bidding makes sense.
Bidding on competitor brand keywords — showing your ad when someone searches a competitor's name — is legal in Google Ads in most markets. Google allows it as long as you don't use the competitor's trademark in your ad copy. For B2B SaaS, competitor bidding works when executed correctly and wastes significant budget when executed broadly. The difference comes down to the query intent.
When does competitor keyword bidding generate pipeline?
"Alternative to [competitor]" and "[competitor] vs [category]" queries. Someone searching "alternative to HubSpot" or "HubSpot vs Salesforce" is explicitly in evaluation mode — they're not committed to HubSpot, they're researching options. This is the highest-intent competitor traffic available. A well-positioned ad for "HubSpot alternative for small teams" showing for these queries reaches buyers at exactly the right moment. Conversion rates on comparison-intent competitor queries are typically 2–3x higher than bare brand-name competitor queries.
When does competitor keyword bidding waste budget?
Bare brand name queries — someone searching just "HubSpot" or "Salesforce." This is almost certainly someone who uses that product or is looking for help with it, not someone evaluating alternatives. They have strong brand loyalty or support intent. Your ad disrupts them, they don't click (or if they do, they don't convert). Quality Score on bare competitor brand terms is also low because your landing page is irrelevant to the query — which means high CPC and poor placement. Not worth it unless you have data showing meaningful conversion from these terms.
What ad copy rules apply to competitor bidding?
You cannot use the competitor's trademark in your ad copy or display URL in most jurisdictions. You can reference the competitor in your landing page content (comparison pages are standard practice). Your headline should position your product, not attack the competitor: "CRM Built for AI-Native Teams" rather than "Better Than HubSpot." Your landing page should be a direct comparison page explaining why your product is different — not a generic homepage that doesn't address the comparison intent.
What budget and bidding approach works for competitor keywords?
Start with a small test budget ($10–20/day) on comparison-intent queries only. Exact match or phrase match on "[competitor] alternative," "[competitor] pricing," "switch from [competitor]." Exclude the bare brand name using negative keywords if needed. Monitor cost-per-conversion against your standard Search campaigns — if competitor keyword CPA is more than 2x your regular Search CPA after 30 days and 50 clicks, the traffic quality isn't worth the premium. Competitor keywords almost always have lower Quality Scores and higher CPCs than your own category keywords.
