How to Do Google Ads Competitor Analysis (Free and Paid Tools)

Competitor analysis in Google Ads means studying how rival advertisers bid on keywords, structure their product feeds, set pricing, and use display and shopping campaigns so you can find gaps, improve your own campaigns, and increase ROAS.

This guide covers the free Google tools built into your Ads and Merchant Center accounts, plus the best third-party tools for deeper research. It also covers Google Shopping-specific tactics, since Shopping competitor analysis works differently from standard search campaign analysis.

Why Google Ads Competitor Analysis Is Different for Shopping Campaigns

Google Shopping ads are generated automatically from your product feed. There are no manual ad copy fields, no keyword lists to bid on directly. This means Shopping competitor analysis focuses on five distinct areas rather than just keywords and bids.

Identify product gaps and opportunities. By examining which products rivals feature in their Shopping ads — including variations, bundles, and seasonal items you can find catalogue gaps. If a competitor consistently shows for “waterproof hiking boots” but never for “waterproof hiking boots for wide feet,” that variation is an untapped opportunity.

• Product categories rivals are most visible in
• Product variations competitors are ignoring
• High-margin niches with low ad competition

Uncover high-performing keywords in product feeds. Shopping ads do not use keywords in the traditional sense, but product titles, descriptions, and attributes act as keyword signals. Competitors ranking well for high-intent Shopping queries have optimized these fields deliberately. Analyze the structure of their product titles common patterns include Brand + Product Type + Key Attribute + Size/Color/Material and identify which search terms their feed content targets.

Benchmark campaign performance. Without competitive context, your metrics are hard to evaluate. A 55% impression share might sound reasonable until you discover the category leader is running at 89%. Competitor benchmarking tells you whether your results are strong or just average.

Discover pricing and creative inspiration. Shopping ads are highly visual. The product image, title, price, and star ratings are all visible before a click. Analyzing how competitors present products, what promotions they highlight, and how they structure pricing gives you direct input for your own campaigns.

Improve targeting and ROI. Understanding which products competitors invest in and which they ignore helps you allocate ad budgets more effectively. Prioritize spending on products where you have a pricing or quality advantage.

How to Analyze Competitor Product Titles and Descriptions

This is the most impactful area of Google Shopping competitor analysis. Since Shopping ads are generated directly from your product feed, your product title is your ad headline. Getting this right is where eCommerce stores win or lose auction placement.

Why product titles matter more than bids. Google’s Shopping algorithm matches your product to search queries based on how well your feed content aligns with what a user typed. A competitor with a perfectly structured product title will often outrank a higher bidder with a vague title. Analyzing competitor title structure is arguably more valuable than analyzing competitor bids.

Step 1 Search your core product keywords on Google Shopping

Open an incognito browser window and search for your main product type. Note the top 5–10 Shopping results. For each result, record the full product title as it appears in the ad.

Step 2 Identify the title pattern they are using

Most high-performing Shopping titles follow a structured pattern. Common formats include:

• Brand + Product Type + Key Attribute + Size/Color/Material
• Product Type + Brand + Model Number + Key Feature
• Brand + Gender + Product Type + Use Case

A top-ranking title might read “Nike Men’s Air Zoom Pegasus 41 Running Shoes – Wide Fit” rather than “Nike Running Shoes.” The former hits more search query variations and signals specificity to Google’s algorithm.

Step 3 Count character usage

Google displays approximately 70 characters of a product title in Shopping ads on desktop, and fewer on mobile. Top competitors tend to front-load the most important attributes in the first 70 characters. Check how much of their title appears before the cutoff and whether the most searchable term appears early.

Step 4 Check for promotional language in descriptions

Product descriptions, which Google uses for query matching but does not display, often contain additional keywords. Use Google’s Ad Transparency Center or third-party tools like SEMrush’s Product Listing Ads feature to access full descriptions where available.

Step 5 Build your attribute audit

Look for these attributes in competitor titles and note which they consistently include:

• Brand name: always front-loaded for branded searches
• Gender or age group: Men’s / Women’s / Kids’
• Material: 100% Cotton / Stainless Steel / Gore-Tex
• Color: when it is a significant search driver
• Size or dimensions: especially for furniture, clothing, and electronics
• Condition: New / Refurbished
• Use case: Running / Hiking / Office

After auditing 10 or more competitor titles, build a spreadsheet of the attributes they include. Identify which attributes appear in top-ranked titles but are missing from yours — those are your immediate feed optimization opportunities.

How to Do Google Ads Competitor Analysis Using Free Google Tools

Google offers a suite of free tools that, when used together, give you a comprehensive view of the competitive landscape. Here is how to use each one specifically for competitor analysis.

Google Ads Keyword Planner

Keyword Planner is primarily a search campaign tool, but it serves a specific purpose in competitor research: understanding the search demand your product feed needs to capture.

To access it, log into your Google Ads account and go to Tools > Planning > Keyword Planner.

The “Get search volume and forecasts” option shows search volume, competition level, and estimated top-of-page bid ranges for any keyword. For example, if you sell t-shirts, enter that term and set your target location to see monthly search volume and competition in your area. A High competition rating with a high bid range means many advertisers are actively investing in that keyword.

Tip: Look for keywords with lower competition but higher monthly search volume. These represent opportunities where you can appear without overpaying.

Discover New Keywords — Analyze a Competitor’s Website

The “Discover new keywords” option doubles as a free competitor analysis tool. You can input a competitor’s website URL to find out which keywords Google associates with their site.

Enter a keyword along with your competitor’s website URL, and Keyword Planner returns that keyword’s search volume plus other keywords your competitor is using, including their volume and competition scores.

To pull a competitor’s full keyword list directly, use the “Start With a Website” option. It returns all keywords Google has indexed for that domain. You can download the list as a CSV for deeper analysis.

You can also use this workflow to build a negative keyword list. Select any irrelevant terms your competitor ranks for that you do not want triggering your ads, and add them as negatives to your Shopping campaigns.

Auction Insights Benchmark Your Campaign Against Competitors

Auction Insights is available only if you are already running Google Ads campaigns. It is one of the most direct free tools for understanding how your campaign stacks up against specific competitors in the same auctions.

The report gives you four key metrics:

Impression Share: How often your ads appear compared to how often they were eligible. If your impression share is significantly lower than a competitor’s, they may be outbidding you or running more targeted campaigns. An impression share of 60–70% is generally considered healthy, but competitive niches can make this harder to achieve.

Overlap Rate: How frequently your ads appear alongside a specific competitor’s ads in the same auctions. A high overlap rate means you are consistently competing for the same audience. This helps you identify who your true competitors are, not just who ranks for similar keywords.

Outranking Share: How often your ad ranks higher than a competitor’s — or appears when theirs does not. If a competitor consistently outranks you, it may indicate higher bids, better ad quality scores, or more precise targeting.

What Is a Good Outranking Share in Google Ads?

Outranking share does not have a universal benchmark — it depends on your niche and the specific competitor. What matters is the trend over time. If your outranking share against a key competitor drops sharply, it typically signals they have increased their bids or improved their quality scores. Monitoring this metric weekly lets you respond before your impression share erodes significantly.

Strategic Use of Auction Insights

Track changes in impression share over time to spot shifts in competitor activity. If a competitor’s impression share suddenly increases, they may be increasing budget or expanding targeting, which will often drive up your cost-per-click.

Auction Insights can also tell you why you are losing impression share. If you are losing to budget, competitors are outbidding you. If you are losing to rank, their ads may have higher quality scores or better relevance. Use this to decide whether to raise bids or improve landing page and feed quality first.

One important note: do not be distracted by large multi-product retailers like Amazon appearing in your Auction Insights data. They bid on related keywords at scale but are rarely your direct competition. Focus on smaller, niche competitors whose product range overlaps directly with yours.

Google Merchant Center for Shopping Competitor Analysis

If you run a WooCommerce or eCommerce store, Google Merchant Center (GMC) is where your product feed lives. The analytics in Google Merchant Center Next include several tools specifically built for competitive research.

Competitor Overlap Analysis. Under Analytics > Products > Competitors in Google Merchant Center Next, you can see the percentage of times your ads appear alongside specific competitor ads, discover competitors you were not aware of, and identify which brands are most visible in your product categories.

Price Comparison Insights. The Pricing tab compares your product prices against the average market price. If your prices are significantly higher than competitors, this report flags it and shows the percentage gap. For products where your pricing is competitive, the report can surface which items would benefit from increased ad spend.

Popular Products Report. This shows which products are currently trending on Google Shopping. Use it to spot products that competitors are promoting heavily and to adjust your own campaigns toward high-demand items.

Can I Use Competitor Brand Keywords in Google Ads?

Yes, you can bid on a competitor’s brand name as a keyword in Google Search campaigns. Google’s policy generally allows this, provided your ad copy does not use the competitor’s trademarked name in a misleading way. You can appear when someone searches for a competitor’s brand, but your ad text itself should not directly reference that brand name unless you have specific rights to do so.

In Google Shopping campaigns, keyword bidding works differently since you do not choose keywords directly. Your product feed content and Google’s algorithm determine which searches trigger your ads.

If a competitor is bidding on your brand name, you can check this through Auction Insights. If their ads appear when users search for your brand, consider increasing bids on your own branded terms to protect that traffic.

How to Check Competitors’ Google Ads Budgets and Spend

You cannot see the exact amount a competitor spends on Google Ads Google does not expose this data. However, you can estimate competitor ad spend through several methods:

• Auction Insights impression share: If a competitor has a very high impression share across many terms, their budget is almost certainly substantial.
• Third-party tools: SEMrush, SpyFu, and Ahrefs all provide estimated monthly ad spend based on traffic modeling. These are estimates, not exact figures, but they give a useful relative benchmark.
• Keyword Planner bid ranges: Top-of-page bid data tells you what advertisers are paying for specific keywords, giving you a floor estimate for what a competitor present in those auctions must be spending.

How to Analyze Competitors’ Google Ads Using Third-Party Tools

Free Google tools cover the basics. For deeper research especially on competitor keywords, ad copy history, and display ads  third-party tools provide significantly more detail.

1. SEMrush PPC Toolkit

SEMrush is one of the most widely used tools for paid search competitive research. Its Advertising Research feature shows which keywords competitors are bidding on, estimated traffic volumes, ad positions, and historical ad copy. The Market Analysis feature gives you a broader view of competitor positioning and spend trends. The Keyword Magic Tool helps identify high-traffic keywords where competition is lower.

2. Ahrefs Site Explorer

Ahrefs is primarily known for SEO, but its Site Explorer includes paid search data. You can see which keywords drive paid traffic to a competitor’s site, view their top-performing ads over time, and identify which landing pages generate the most paid search clicks.

3. SpyFu PPC Research

SpyFu specializes in competitor paid search intelligence. It shows a competitor’s ad history, their top-performing ads, which keywords they are targeting, and estimated budget ranges. Its Keyword Overlap feature identifies shared keywords between your campaign and a competitor’s, surfacing gaps you may be missing.

4. iSpionage

iSpionage focuses on keyword monitoring and ad copy analysis. You can track which keywords competitors are bidding on, review their ad copy for messaging patterns, and evaluate CTR and ad position trends over time. It is particularly useful for identifying when competitors change their bidding strategy.

5. AdBeat

AdBeat focuses primarily on display advertising but also covers Google Ads. It shows the top-performing creatives competitors are running, ad spend trends, and which networks their ads perform best on. If display advertising is a significant part of your competitors’ strategy, AdBeat provides visibility that most search-focused tools miss.

How to Spy on Competitors’ Google Display Ads

For display ads specifically, you have several options:

• Google’s Ad Transparency Center (adstransparency.google.com) a free tool that shows ads any advertiser is currently running across Google’s network, including display and YouTube. Search by advertiser name to see their active creatives.
• AdBeat and SpyFu both offer display ad tracking with historical creative data.
• Manual SERP research search for your core product keywords in incognito mode and note which display ads appear in retargeting across other sites after visiting competitor pages.

Frequently Asked Questions

How do I find out what keywords my competitors are bidding on in Google Ads?

Use Google Ads Keyword Planner’s “Start With a Website” option and enter a competitor’s URL. It returns the keywords Google associates with that domain. For paid keyword data specifically, third-party tools like SEMrush, SpyFu, and Ahrefs provide estimated keyword lists from competitor campaigns with traffic and bid range data.

What is Auction Insights in Google Ads?

Auction Insights is a free report inside Google Ads that shows how your campaigns perform relative to other advertisers competing in the same auctions. It provides impression share, overlap rate, outranking share, and position above rate metrics. It is only available if your campaign has enough impression volume to generate statistically meaningful data.

What is the outranking share in Google Ads?

Outranking share measures how often your ad ranks above a specific competitor’s ad, or appears in an auction where their ad does not. A higher outranking share against a competitor means your ads are more consistently visible than theirs in shared auctions. This metric is most useful when tracked over time to detect changes in competitor bidding behavior.

How do I check if a competitor is bidding on my brand name in Google Ads?

Run a search for your brand name in Google while logged out or in incognito mode and check if competitor ads appear in the results. You can also run Auction Insights for your branded keyword campaigns if a competitor consistently appears in those reports, they are bidding on your brand terms.

Can I see how much a competitor is spending on Google Ads?

No exact spend data is publicly available. Third-party tools like SEMrush and SpyFu provide estimated monthly ad spend based on keyword traffic modeling. These estimates are directionally useful but not precise. Auction Insights impression share data gives an indirect signal of budget scale.

What is the best free tool for Google Ads competitor analysis?

For most advertisers, the combination of Google Ads Keyword Planner (competitor keyword research), Auction Insights (head-to-head campaign benchmarking), and Google Merchant Center Next’s Competitors report (for Shopping campaigns) covers the core use cases without any additional cost.
