PPC Spying: How to Analyse Your Competitors’ Google Ads

Why Should You Analyse Competitors’ PPC Campaigns?

Your competitors are spending money on Google Ads right now. Some of that spend is generating strong returns. Some of it is wasteful. By analysing their campaigns, you can learn from their successes and avoid their mistakes without spending a cent of your own budget on testing.

Competitor PPC analysis reveals which keywords are worth targeting, which ad messages resonate with your shared audience, and which landing page approaches drive conversions. It is essentially free market research that shows you what is already working in your industry. Think of your competitors as an involuntary R&D department.

This is not about copying competitors blindly. It is about making informed strategic decisions based on real market data. When you understand the competitive landscape, you can position your SEM campaigns to stand out rather than blend in. The businesses that conduct regular competitor analysis consistently outperform those that operate in a vacuum.

In the Singapore market specifically, where many industries have a handful of dominant advertisers, understanding what those advertisers are doing gives you a massive advantage. You can identify gaps in their strategy that represent opportunities for your business.

What Tools Can You Use for PPC Competitor Research?

Several tools make competitor PPC analysis straightforward. Here are the most effective ones, ranked by usefulness:

Google Ads Transparency Centre

Google’s own tool lets you see any advertiser’s active ads across Google Search, YouTube, and the Display Network. It is free and shows ad creatives, run dates, and targeting regions. Search for a competitor’s name to see every ad they are currently running. This is your starting point because the data is directly from Google and completely accurate.

SEMrush

SEMrush’s Advertising Research module reveals a competitor’s paid keywords, estimated monthly ad spend, ad copy history, and traffic share. You can also see which keywords they have started or stopped bidding on over time. The historical data is particularly useful for spotting trends and seasonality patterns.

SpyFu

SpyFu specialises in competitor keyword research. It shows every keyword a competitor has ever bought on Google Ads, along with their ad variations and estimated budget. The historical data going back years is particularly useful for spotting seasonal patterns and long-term strategy shifts.

Ahrefs

While primarily an SEO tool, Ahrefs provides PPC keyword data and shows which paid keywords drive the most traffic to competitor sites. Its content gap analysis works for PPC keyword opportunities too, showing you keywords your competitors bid on that you do not.

Google Auction Insights

Available directly in your Google Ads account, Auction Insights shows which competitors appear alongside your ads and how often. It reveals impression share, overlap rate, and position above rate. This is the only tool that uses your actual auction data rather than estimates.

How Do You Analyse Competitors’ Keywords?

Start by identifying which keywords your top three to five competitors are bidding on. Most PPC research tools provide this data sorted by estimated traffic value or search volume. For a foundational understanding of keyword strategy, see our guide on keyword advertising.

Look for three types of opportunities:

Keywords you share. Both you and your competitors bid on these. Compare your ad positions, Quality Scores, and CPCs. If a competitor consistently outranks you on a shared keyword, study their ad copy and landing page to understand why. The answer is usually better ad relevance, a higher Quality Score, or simply a bigger bid.

Keywords they target that you do not. These represent gaps in your campaign. Evaluate each one for relevance and commercial intent. If a competitor is spending consistently on a keyword you have missed, it likely converts for them. Test the most promising ones with a small budget before committing fully.

Keywords they have stopped bidding on. If a competitor dropped a keyword after months of spending, it probably did not convert well for them. This saves you from making the same expensive mistake. Why pay to learn something your competitor already learned the hard way?

Create a spreadsheet tracking competitor keywords by search volume, estimated CPC, and competitive density. This becomes your keyword expansion roadmap, prioritised by the intelligence your competitors have already paid to generate. Update it monthly as the competitive landscape shifts.

What Can You Learn from Competitors’ Ad Copy?

Ad copy analysis reveals what messages your market responds to. Study competitors’ ads systematically rather than glancing at them casually. The patterns you uncover will inform not just your PPC ads but your entire marketing messaging.

Pay attention to:

• Headlines: What benefits or features do they lead with? Do they use numbers, questions, or direct offers? Which emotional triggers are they pulling?
• Descriptions: How do they differentiate themselves? What objections do they address? Do they mention pricing, guarantees, or social proof?
• Calls to action: What specific actions do they ask for? Free quotes, consultations, instant pricing, free audits? The CTA reveals their conversion strategy.
• Extensions: Which ad extensions do they use? Sitelinks, callouts, structured snippets, and call extensions all provide additional real estate and information. Competitors using more extensions typically have higher CTRs.
• Offers and promotions: Are they leading with discounts, free trials, or guarantees? If every competitor offers “free consultation”, you need a different hook to stand out.

The ads that have been running longest are usually the best performers. If a competitor has used the same headline for six months, it is almost certainly their highest-performing variation. Note the patterns across multiple competitors. Common themes indicate proven messaging that resonates with your shared audience.

Then ask yourself: where is the gap? If every competitor talks about price, lead with quality. If they all focus on speed, emphasise thoroughness and results. Differentiation wins clicks as much as bid amounts do.

How Do You Analyse Competitors’ Landing Pages?

The ad is only half the equation. The landing page determines whether clicks become conversions. Click through your competitors’ ads (use incognito mode to avoid skewing their data) and evaluate their landing pages critically.

Assess these elements:

• Headline alignment: Does the landing page headline match the ad promise? Disconnect here is the number one conversion killer.
• Page structure: How is information organised? What do they prioritise above the fold? Is the CTA visible without scrolling?
• Social proof: Do they feature testimonials, reviews, client logos, or case studies? How specific is the proof?
• Conversion mechanism: What do they ask for? Short form, long form, phone call, live chat, WhatsApp? In Singapore, WhatsApp CTAs often outperform traditional forms.
• Trust signals: Certifications, awards, guarantees, security badges? Government badges like PSG and IMDA approval carry significant weight with Singapore business owners.
• Page speed: Use PageSpeed Insights to check their performance scores. If their pages are slow, you have an easy advantage.

Do not copy competitors’ landing pages. Instead, identify what they do well and what they miss, then build pages that outperform theirs. If every competitor uses a long-form sales page, a clean, concise page might stand out. If none of them offer a compelling guarantee, adding one could be your differentiator.

Competitor Analysis for Singapore-Specific Markets

The Singapore market has unique competitive dynamics that affect how you should interpret competitor data.

Small market, high visibility. Singapore’s search market is relatively small compared to the US or UK. This means a few dominant advertisers can capture the majority of impressions. Identifying who those dominant players are and where they have gaps is more important here than in larger markets where there is room for everyone.

Seasonal patterns. Singapore businesses see predictable seasonal shifts. Chinese New Year, the Great Singapore Sale, year-end budget cycles for B2B, and school holiday periods all affect search behaviour and competitor spending. Track how your competitors adjust their campaigns around these events so you can plan accordingly.

PSG and grant messaging. Many Singapore businesses advertise PSG grant eligibility or other government incentives. If your competitors are using this messaging and you are eligible too, you need to match it. If they are not mentioning it, including it in your ads gives you a unique angle that can significantly improve click-through rates.

Multi-channel presence. Check whether your competitors are also investing in organic SEO. Competitors who rank well both organically and in paid ads are harder to displace. For those competitors, you may need to focus on keywords where their organic presence is weaker while building your own long-term SEO strategy to compete across both channels.

Setting Up Ongoing Competitor Monitoring

A one-time competitor analysis gives you a snapshot. Ongoing monitoring gives you a strategic advantage. Set up systems to track competitor changes automatically so you are never caught off guard.

Set up Google Alerts for competitor brand names. You will be notified whenever they are mentioned online, including new campaigns, PR coverage, and customer reviews. This context helps you understand their broader strategy beyond just PPC.

Schedule monthly PPC audits. Block two hours each month to run through your competitor analysis tools, check for new keywords, review ad copy changes, and visit updated landing pages. Document everything in a shared spreadsheet so you can spot trends over time.

Use Auction Insights reports. Pull these from Google Ads monthly and track changes in competitor impression share, overlap rate, and position above rate. A sudden increase in a competitor’s impression share often signals a budget increase or new campaign launch that you need to respond to.

Monitor ad copy rotations. When a competitor tests new ad copy, note it. If the new copy replaces the old one permanently, it performed better. If they revert, it did not. You are getting free A/B test results without spending a dollar.

How Do You Turn Competitor Insights into Action?

Research without action is just entertainment. Here is how to translate your competitor analysis into campaign improvements that generate revenue:

Build your gap keyword list. Take the keywords your competitors target that you do not, filter for commercial intent and relevance, and add them to your campaign plan. Test with a small budget first to validate performance. For a detailed approach, read our guide on improving your Google Ads conversion rate.

Write better ads. Use the patterns from competitor ad copy as a starting point, then improve on them. If competitors emphasise price, lead with quality and results. If they are generic, be specific. Differentiation wins auctions as much as bid amounts do.

Upgrade your landing pages. Apply the best practices you observed across competitor pages while fixing the gaps they leave. Faster pages, stronger social proof, and clearer value propositions give you the conversion rate advantage.

Set up ongoing monitoring. Competitor strategies change. Set a monthly cadence to review competitor ads, keywords, and landing pages. This keeps your campaigns responsive to market shifts rather than static.

Frequently Asked Questions

Is it legal to spy on competitors’ PPC campaigns?

Yes. Analysing publicly visible ads, keywords, and landing pages is standard competitive research. Google’s own Transparency Centre is designed to make ad information accessible. You should not attempt to access competitors’ private accounts or click on their ads to waste their budget, as click fraud is both unethical and illegal.

How accurate are third-party PPC spy tools?

Tools like SEMrush, SpyFu, and Ahrefs provide estimates, not exact figures. Their keyword data and traffic estimates are directionally accurate but should be treated as approximations. The real value is in relative comparisons and trend identification rather than exact numbers. Use multiple tools to triangulate and get a more complete picture.

How often should I analyse my competitors’ PPC campaigns?

Conduct a thorough competitor analysis quarterly, with lighter monthly check-ins on ad copy changes and new keywords. In highly competitive or fast-moving industries like legal, finance, or education in Singapore, monthly deep dives are worthwhile. Set calendar reminders so it becomes a consistent practice rather than an afterthought.

Should I bid on my competitors’ brand names?

It can be effective for capturing high-intent traffic, but the clicks tend to be expensive due to low Quality Scores. Test with a small budget and a dedicated landing page that clearly differentiates your offer. Monitor conversion rates closely. If the cost per acquisition is sustainable, scale it up. If not, redirect that budget to non-branded keywords.

What should I do if a competitor starts bidding on my brand name?

First, make sure you are bidding on your own brand name. Brand keywords are cheap and prevent competitors from stealing your traffic. Second, check that your organic listing for your brand is strong. Third, consider whether bidding on their brand name in return makes economic sense. Often, simply protecting your own brand is the most cost-effective response.
