How to Steal Competitor Traffic with Custom Intent Audiences

If you want to know how to steal competitor traffic with custom intent audiences, the short version is this: you build a custom segment inside Google Ads using your competitors’ branded search terms and website URLs, then show ads to those people on YouTube, Display and Demand Gen while they are still deciding. It is one of the few targeting methods that lets you get in front of somebody who is actively researching a rival, without bidding on trademarked keywords in Search. Done properly, it turns their marketing spend into your pipeline.

Custom intent audiences were renamed custom segments a few years back, but most advertisers still use the old name. The mechanics are the same, and they have quietly become one of the cheapest sources of qualified traffic in the account.

What a Custom Segment Actually Does

A custom segment tells Google: find me people who behave like this. You feed it two kinds of signal, keywords and URLs, and Google builds an audience of users whose recent searches, browsing and app usage match that behaviour. According to Google Ads Help, these segments can be built from search terms people have used, websites they have browsed, and apps they have installed.

The competitor angle is obvious once you see it. If somebody searched “acme crm pricing” last week, or spent time on your rival’s features page, they are mid-research and they have money in hand. You are not interrupting a stranger, you are joining a conversation that has already started.

• Keyword signals: competitor brand names, product names, “[competitor] alternative”, “[competitor] reviews”, “[competitor] vs”.
• URL signals: competitor homepages, pricing pages, comparison pages, and the review sites where they get listed.
• App signals: useful if your category has a well-known app your rivals own.

Important caveat: Google does not target the exact people who visited those URLs. It uses the URL to understand the type of person interested in that content, then finds a lookalike pool. That is why signal quality matters more than signal quantity.

Where You Can (and Cannot) Run Them

Custom segments are available across Display, YouTube, Demand Gen, Discovery and Gmail placements, plus Performance Max as an audience signal. In Search campaigns they work as an observation layer or a targeting layer, but they do not let you appear for competitor brand queries on their own, you still need keywords for that.

This distinction trips people up constantly. If your goal is competitor brand search, that is a trademark and bidding conversation with its own rules. If your goal is cheap, high-intent reach at a fraction of Search CPCs, custom segments on YouTube and Display are where the value sits. Our breakdown of Search Network vs Display Network covers when each channel earns its budget.

Building a Competitor Custom Segment: Step by Step

1. List 8 to 15 real competitors. Direct rivals first, then the aggregators and review sites your buyers use (Capterra, Yelp, Houzz, whatever fits your category).
2. Pull their branded search terms. Brand name, brand plus pricing, brand plus reviews, brand plus alternative, brand plus login. Login queries are surprisingly good in B2B because they signal active users who may be unhappy.
3. Collect specific URLs, not just homepages. A pricing page or a product comparison page tells Google far more about intent than a homepage does.
4. Open Tools, then Audience Manager, then Custom Segments. Name it something you will recognise in six months, like “Custom Intent, Competitor Pricing Pages, Q1 2026”.
5. Choose the intent option. Select “people who searched for any of these terms on Google” rather than the broader interest option. It is narrower and considerably more valuable.
6. Check the estimated reach. Anything under roughly 50,000 weekly impressions will struggle to spend. Anything over several million usually means your signals are too generic.
7. Layer, do not stack blindly. Add geographic limits, and consider excluding existing customers and recent converters so you are not paying to reach people you already own.

Keep competitor segments in their own campaign or at minimum their own ad group. Mixing them with general prospecting makes the reporting useless, and you will never know which lever actually worked.

The Message Has to Change, Not Just the Targeting

Targeting a rival’s audience with your generic brand video is a waste of impressions. These people already know the category, already have a frontrunner, and are looking for a reason to either commit or reconsider. Speak to that specific moment.

• Lead with the comparison: “Still comparing quotes?” outperforms “We are the leading provider” by a wide margin in our experience.
• Name the friction: setup fees, long contracts, slow support, minimum order quantities. Whatever your competitors are quietly bad at.
• Give a switching incentive: free migration, contract buyout, first month waived, free site audit.
• Keep it short on YouTube: a 6 second bumper plus a 15 second in-stream sequence usually beats one 30 second spot on cost per view.

The copy principles that work in Search still apply here, and our guide on writing ad copy that drives clicks is worth reading before you write a single headline. Specificity beats cleverness almost every time.

Send Them Somewhere Built for Comparison

Competitor-audience traffic converts badly on a homepage. These visitors are in evaluation mode, so they want a side-by-side, a price, and proof that switching will not ruin their week. Build a dedicated comparison or alternatives landing page and keep the path to conversion short.

If you are running an ecommerce store, the checkout itself is usually where the leak is, and tightening it up costs nothing in media spend. Our walkthrough on customising the WooCommerce checkout page for higher conversions covers the field-by-field detail. For service businesses, even simple layout changes help, and you can handle most of them with our notes on customising a WordPress theme without knowing how to code.

What Results Look Like, Realistically

Expectations matter here because custom segments rarely produce last-click miracles. On Display, competitor-intent segments commonly run a click-through rate between 0.3% and 0.9%, with CPMs in the $3 to $12 range depending on category. YouTube in-stream cost per view for a tight competitor segment tends to land between $0.02 and $0.08.

The honest read is that most of the value shows up as assisted conversions, brand search lift and remarketing pool growth. Give a competitor campaign at least 4 to 6 weeks and 100 to 200 conversions worth of data across the account before you judge it. Layering it with remarketing to win back lost visitors is usually what closes the loop, because the first touch rarely converts cold.

Two housekeeping items save real money. Add exclusions for your own site visitors and current customers, and run a placement exclusion list monthly so you are not funding app inventory and made-for-advertising sites. The same discipline applies as with negative keywords protecting your ad budget.

Common Mistakes That Kill Competitor Campaigns

• Mixing generic category keywords into the segment. Adding “crm software” to a list of brand names dilutes the intent and balloons reach.
• Using competitor logos or names in creative. Trademark policy and basic legal caution both say do not. Say “alternatives to the big providers”, not the brand.
• Judging on last-click only. Turn on view-through and use a data-driven attribution model before you declare the campaign dead.
• Too many segments, too little budget. Five separate competitor audiences on $20 a day each will never exit the learning phase.
• Ignoring privacy shifts. Signal loss is real, and Google’s own Privacy Sandbox changes are reshaping how browsing-based audiences are built, so first-party data should always sit alongside these segments.

Once the structure is stable, test the variables one at a time. Our notes on A/B testing Google Ads and on using audience targeting to refine search campaigns pair well with this playbook.

Frequently Asked Questions

Can I target my competitor’s website visitors directly with Google Ads?

No, you cannot target the actual individuals who visited a competitor’s site, since that data belongs to them. What you can do is add competitor URLs as a signal in a custom segment, and Google will find users whose browsing and search behaviour resembles that audience.

Are custom intent audiences and custom segments the same thing?

Yes, custom segments is the current name for what used to be called custom intent and custom affinity audiences, merged into one tool. The interface consolidated them, so you now build one segment and choose whether to weight it toward search intent or broader interests.

How much budget do I need to test a competitor custom segment?

Plan for at least $30 to $50 per day for 30 days, roughly $900 to $1,500 for a fair test. Below that, Google struggles to gather enough conversion data and the campaign stalls in the learning phase for weeks.

Is it legal to bid on a competitor’s brand name?

In most markets, including the US, bidding on a competitor’s trademark as a keyword is permitted, but using their trademark in your ad text generally is not. Google will review complaints, so keep the brand name out of headlines, descriptions and video creative.

Do custom segments work in Performance Max?

Yes, you can add a custom segment as an audience signal in a Performance Max asset group, which helps the algorithm find the right pool faster. It is a suggestion rather than a hard restriction, so the campaign will still expand beyond that audience over time.
