How to Do Google Ads Competitor Analysis (The Way Agencies Actually Do It)

Most advertisers know their CPCs went up. They don’t know who drove them up.

That’s the real cost of skipping competitor analysis in Google Ads — not just leaving money on the table, but making budget, bidding, and messaging decisions in a vacuum. Before you can fix your campaigns, you need to understand the competitive environment those campaigns are running inside.

This guide covers exactly how to do that — using the tools inside Google Ads, the third-party tools worth paying for, and a few methods that most advertisers never think to use.

Start With Auction Insights — The Competitive Data You Already Have

Before you buy any third-party tool, go to your Google Ads account and pull the Auction Insights report. It’s the most honest competitive dataset you have access to, and it’s criminally underused.

You’ll find it at the campaign, ad group, or keyword level. Navigate to any of those views, click the “Auction insights” tab, and Google will show you which competitors are appearing in the same auctions you are — and how you stack up against them on six metrics.

The ones that actually matter:

• Impression Share — what percentage of eligible auctions you showed up in (vs. them). If a competitor has 85% impression share and you have 40%, they’re dominating auctions you’re losing before the click even happens.
• Overlap Rate — how often you and a specific competitor appear in the same auction. High overlap with a well-funded competitor is a signal to look hard at your bid strategy and budget.
• Position Above Rate — how often a competitor’s ad appeared above yours when you both showed. If one competitor is above you 70%+ of the time, you’ve got a bid gap, a Quality Score gap, or both.
• Top of Page Rate — what share of the time their ads hit the top positions (above organic results). This tells you how aggressive their bidding is.

The move most people skip: segment Auction Insights by device and by time. A competitor might be dominating on mobile but weak on desktop. That’s an opportunity. If you’re being outgunned Monday through Friday but the competitor drops off on weekends, you can adjust your ad scheduling to take impression share when they’re not fighting for it.

For a deeper look at how impression share signals competitive pressure, this breakdown of Google Ads impression share metrics is worth reading alongside your Auction Insights data.

How to Actually Spy on Competitors’ PPC Strategies (The Right Tools)

Auction Insights tells you who you’re competing against and how often. It doesn’t tell you what keywords they’re bidding on, what their ads say, or what landing pages they’re sending traffic to. For that, you need third-party tools.

Here’s how we actually use them:

SEMrush (or Ahrefs)

Type a competitor’s domain into SEMrush’s “Advertising Research” tab and you’ll see their estimated paid keyword list, their ad copy history, and their monthly PPC traffic trends. This isn’t perfect data — it’s modeled from clickstream panels — but it’s directionally accurate enough to be genuinely useful.

What to look for: keywords where the competitor has been running ads consistently for 6–12 months. Consistency is a signal. If they’ve been bidding on a term for a year, it’s working for them. That’s a term you need to be on too — or one you need to understand why you’ve avoided.

Also look for keywords they’re not running. Large competitors often leave long-tail, high-intent terms uncovered because their campaigns aren’t managed tightly enough. Those gaps are where you can pick up qualified clicks at lower CPCs.

SpyFu

SpyFu is particularly good for competitive ad copy research. You can see the actual ad headlines and descriptions a competitor has run over time, including variants they’ve tested and retired. If you’re about to write RSAs for a competitive keyword and you want to know what messaging the market has already been exposed to, SpyFu’s ad history is a fast way to get context. (For more on RSA strategy, this guide on writing high-converting Google Ads copy covers a testing framework we’ve used across hundreds of accounts.)

Google’s Own Ad Transparency Center

This one is free and almost nobody uses it. Go to adstransparency.google.com, search for a competitor’s brand name, and you’ll see the ads they’re currently running across Google’s network. It won’t show you keywords or bids, but it shows live creative — which is useful when you want to know how they’re positioning their offer right now, not six months ago.

Manual Google Searches (Yes, Really)

Don’t underestimate the value of just Googling your target keywords in an incognito window. Look at who’s in the top four ad positions. Look at their headlines, their descriptions, their sitelinks and callouts. Take screenshots. Do this across your 20 highest-priority keywords and you’ll have a picture of the competitive ad landscape that no tool can fully replicate — because you’re seeing it the way your potential customer sees it.

Decoding Competitor Keywords — What to Steal, What to Ignore, and What to Block

Competitor keyword research has three outputs. Most people only use the first one.

1. Keywords to add to your own campaigns. If three of your top competitors are all bidding on “enterprise project management software free trial” and you’re not, that’s a gap. Use strategic keyword research to validate search volume and intent before adding, but competitive coverage data is a legitimate shortcut to finding terms worth testing.

2. Messaging insights. The keywords competitors bid on reveal how they’re thinking about their customer. If a competitor is heavily targeting “QuickBooks alternative” or “Salesforce replacement,” they’re positioning against a category leader. That’s a strategic direction you either want to mirror or actively counter.

3. Negative keyword opportunities. If your search terms report (which you should be reviewing weekly) shows you’re matching to competitor brand names you didn’t intend to target, that’s a negative keyword problem. Conversely, if you’re running broad match campaigns and your ads are showing for a competitor’s brand, you’re burning budget on low-converting traffic unless you’re explicitly running a competitor campaign strategy.

On that last point: bidding on competitor keywords is its own tactical decision with real tradeoffs. We’ve written a detailed honest framework on whether you should bid on competitor keywords in Google Ads — it’s worth reading before you go down that road.

Reading Competitor Ad Copy Like a Strategist, Not a Copywriter

When most people look at a competitor’s ads, they’re asking “what did they write?” The right question is “what are they trying to prove, and to whom?”

Ad copy reveals positioning strategy. Here’s what to look for:

What proof points do they lean on? If every competitor is leading with price (“starting at $X/month”), and you’re not the cheapest option, you know not to compete on price. You also know there’s likely an opening to lead with quality, speed, or outcomes — something the category isn’t saying.

What objections are they trying to pre-empt? “No contracts,” “setup in 24 hours,” “cancel anytime” — these headline choices tell you what objections the market has. If multiple competitors address the same concern, it’s a real objection you need to address too, either in your ad copy or on your landing page.

What CTAs do they use? “Get a free demo” vs. “Start free trial” vs. “See pricing” signal different funnel stages and different conversion philosophies. If all your competitors are pushing demos and you’re pushing a free trial, you might be out of step with what buyers in your category expect — or you might have a real differentiation point. Context matters.

What do their sitelinks say? Sitelinks are underrated competitive intelligence. They show you what a competitor thinks matters enough to feature: case studies, integrations, pricing pages, specific use cases. If a competitor has six sitelinks pointing to industry-specific use case pages and you don’t have that content, you’re probably losing relevance signals.

Analyzing Competitor Landing Pages — The Research Most Advertisers Skip

Click the ad. Go to the landing page. Do this for your top five to ten competitors across your most important keywords. It takes thirty minutes and it’s one of the highest-leverage research activities you can do.

What you’re evaluating:

• Message match — does the landing page headline match the ad headline? Many competitors fail here, which is a conversion rate opportunity you can exploit by being tighter on relevance.
• Offer structure — are they offering a demo, a free trial, a download, or just a contact form? If every competitor is gating behind a demo request, a self-serve signup or a free resource might convert better for you because it removes friction.
• Social proof — what logos, testimonials, and review counts are they showing? If they have 500 G2 reviews and you have 12, that’s a trust gap you need to address before spending more on clicks.
• Page speed — run their URL through Google’s PageSpeed Insights. If their mobile page is slow and yours is fast, you have a Quality Score and conversion rate advantage you should be protecting.

For a detailed framework on what separates high-converting landing pages from the ones that bleed your budget, this guide on Google Ads landing page best practices covers the elements that actually move conversion rates.

Turning Competitive Intelligence Into Campaign Decisions

Here’s where most competitor analysis efforts die: in a slide deck that nobody acts on.

The point of all this research is to change what you bid on, how much you bid, what your ads say, and where you send traffic. If it doesn’t change any of those four things, it was a research exercise, not strategy.

Concrete outputs from a proper competitor analysis:

Bid adjustments: If Auction Insights shows one competitor consistently outranking you on your highest-converting keywords, that’s a signal to either raise bids on those terms or improve your Quality Score (ad relevance + landing page experience + expected CTR). Throwing budget at a keyword you’re losing on Quality Score grounds is a waste. Fix the score first, then invest more aggressively.

Keyword list expansion or pruning: Add the high-intent terms competitors are covering that you aren’t. Remove or add negatives around terms where you’re showing up in irrelevant competitive contexts. If you want a systematic approach to building this into your audit process, this step-by-step Google Ads account audit framework includes competitor analysis as a core audit component.

Ad copy testing: If you’ve identified a message angle that no competitor is using, that becomes a test hypothesis. Pin it in a headline variant, run it against your control for four to six weeks with enough volume to get statistical significance, and measure CTR and conversion rate — not just impressions.

Budget reallocation: If a competitor is clearly dominating a keyword cluster you care about and you’re significantly underfunded to compete there, you have two choices: find the adjacent terms they’re ignoring and own those, or bring in enough budget to compete directly. Trickling spend into a competitive auction you can’t win is how you get expensive non-converting clicks.

Frequently Asked Questions

What is the best free tool to spy on competitors’ Google Ads?

Google’s own Auction Insights report is the most reliable free tool — it’s based on real auction data from your account. The Google Ads Transparency Center is a close second for seeing live competitor creatives at no cost. For keyword-level competitive data, most tools (SEMrush, SpyFu, SimilarWeb) require a paid subscription, though many offer limited free lookups.

How often should I run a Google Ads competitor analysis?

Do a full competitive audit quarterly. Check Auction Insights monthly — or weekly if you’re in a high-velocity market where competitors change strategies frequently (e.g., SaaS, finance, legal). When you see a sudden spike in CPC on a key term, check Auction Insights immediately. Something changed in the competitive landscape.

Can I see exactly what keywords my competitors are bidding on?

Not exactly — Google doesn’t publish that data. What third-party tools like SEMrush and SpyFu give you is modeled estimates based on traffic pattern analysis. It’s directionally accurate but not a perfect readout. Treat it as a starting point for your own keyword research validation, not ground truth.

Is it legal to bid on competitor brand names in Google Ads?

In most markets, yes — bidding on a competitor’s branded keywords is generally legal under trademark law, as long as you don’t use their trademarked name in your ad copy. Google enforces trademark policies on ad text, not on keyword targeting. That said, the ROI case for competitor keyword campaigns isn’t always there. Our honest framework on bidding on competitor keywords covers when it makes sense and when it doesn’t.

What’s the difference between Auction Insights and third-party PPC spy tools?

Auction Insights only shows you competitors who appeared in the same auctions as your active keywords — so it’s limited to your current keyword coverage. Third-party tools show you the broader landscape of what a competitor is bidding on across all their campaigns, including keywords you’re not currently targeting. You need both to get a complete picture.

How do I know if my competitors are increasing their Google Ads spend?

Auction Insights is your best proxy. If a competitor’s impression share or Top of Page Rate is climbing month over month, they’re likely increasing budget or bids — or both. You can also track their estimated traffic trends in SEMrush over time. A competitor whose paid traffic estimate is growing 20% quarter over quarter is investing more heavily. Plan accordingly.

If You’re About to Hire an Agency, This Is What They Should Be Doing

Competitor analysis isn’t a one-time onboarding deliverable — it’s an ongoing input into your campaign strategy. Any agency worth hiring should be pulling Auction Insights monthly, reviewing competitor ad copy quarterly, and building competitive keyword gaps into their keyword strategy from day one.

If the agency you’re evaluating can’t tell you who your top three auction competitors are within the first week, or can’t explain how they’ll use that intelligence to shape your campaigns, that’s a gap worth probing.

If you want a second opinion on how your current campaigns stack up competitively — or you want to know what your market looks like before you start spending — we offer a free Google Ads audit that includes a competitive landscape review. You’ll get a real analysis, not a sales pitch dressed up as one.
