Key Ad Performance Metrics to Track
Core Metrics for Ad Analysis
Tracking the right metrics can be the difference between a campaign that thrives and one that drains your budget.
- Impressions: This metric counts how many times your ad is displayed, giving you a sense of your campaign's reach. If you're pulling impression data from competitor sites, you can also uncover insights about market share and brand visibility trends.
- Click-through rate (CTR): CTR measures the percentage of people who click on your ad after seeing it. With industry benchmarks hovering around 0.90%, this metric helps you gauge how compelling your ads are.
- Cost-per-click (CPC): CPC shows how much you're paying for each click. Lower CPCs indicate you're spending wisely, while higher costs might suggest rising competition or targeting inefficiencies.
- Conversion rates: This metric tells you how many clicks actually lead to sales or sign-ups. Testing different ad elements through A/B testing can reveal what resonates most with your audience.
- Cost-per-acquisition (CPA): CPA calculates how much you're spending to secure a new customer. For instance, WordStream reports that the average CPA for Facebook ads across industries is $18.68. Keeping an eye on CPA helps you refine your sales funnel and craft offers that reduce costs.
- Return on ad spend (ROAS): Unlike overall ROI, ROAS focuses specifically on the returns generated by your ad campaigns. It helps you decide which campaigns deserve more investment and which might need reworking - or scrapping.
These metrics not only shine a spotlight on your campaign's performance but also provide a foundation for analyzing your competitors.
Competitor Analysis Through Metrics
Looking beyond your own data can reveal valuable insights into the broader market landscape. Comparing your performance metrics with those of competitors can sharpen your strategy and help you avoid common pitfalls. For instance, the average business reportedly wastes 76% of their PPC budget on ineffective tactics, often because they fail to monitor competitor activity.
- Ad placement analysis: This involves tracking where competitors place their ads and how often they run campaigns. Such insights can help you pinpoint the best times to launch your own campaigns and spot opportunities they might be missing.
- Keyword competition data: By analyzing which companies are targeting the same keywords, you can refine your approach. For example, one e-commerce client saved 40% on CPCs during Black Friday by focusing on long-tail keywords while competitors stuck to broader terms. They also shifted to desktop targeting when others poured resources into mobile, yielding 25% more conversions.
- Creative content patterns: Keeping tabs on competitor messaging can reveal shifts in strategy. In one case, a client noticed a drop in conversions despite maintaining strong ad positions. Competitor analysis showed that rivals had pivoted to messaging about "recession-proof" solutions, prompting the client to adjust their own campaigns.
"Monitoring competitor websites isn't about following the next move; it's about anticipating that move."
– Sandro Shubladze, CEO and Founder, Datamam
- Landing page analysis: Scraping competitor landing pages can expose gaps in their strategies, such as funnel structures or offer tactics you can improve upon.
US Formatting Standards for Metrics
When it comes to interpreting and sharing data, consistent formatting is key. Using standard US formatting ensures clarity and avoids confusion across teams and stakeholders.
- Currency formatting: Use a dollar sign followed by commas for thousands. For example, write $1,000.00 for exact figures or $1,000 for rounded values. Always repeat the dollar symbol when listing multiple amounts to maintain clarity.
- Date formatting: Stick to the month-day-year format (MM/DD/YYYY). For example, use 03/15/2025 or March 15, 2025. Slashes (/) are commonly used for numeric dates.
- Number formatting: Add commas to separate groups of three digits for numbers over 1,000. For example, write 125,000 impressions. Percentages should include decimals where appropriate, such as a 2.45% conversion rate.
- Time formatting: Marketing reports typically use the 12-hour clock with AM/PM designations, like 2:30 PM EST. Only use the 24-hour format for specific contexts like military or scientific reporting.
- Percentage displays: Place the percent symbol directly after the number without spaces, like 15.7% CTR or 3.2% conversion rate. Be consistent with decimal places, usually sticking to one or two depending on the level of precision needed.
These formatting conventions are especially useful when integrating scraped data into analytics tools or sharing reports across teams. Consistency reduces misunderstandings and ensures accurate interpretation of your metrics.
Tools and Methods for Scraping Ad Data
Common Scraping Tools Overview
Web scraping tools come in all shapes and sizes, from simple browser extensions to advanced platforms designed for enterprise-level use. For developers familiar with Python, BeautifulSoup and Scrapy are long-standing favorites. BeautifulSoup is great for parsing HTML and XML documents, making it ideal for scraping static elements on web pages. However, it struggles with JavaScript-heavy sites.
Scrapy, on the other hand, is built for larger-scale projects. It offers features like request management and data export right out of the box. That said, it comes with a steeper learning curve and requires regular updates to keep up with website changes.
If you’re looking for no-code solutions, platforms like Octoparse (starting at $75/month), ParseHub (starting at $189/month), and Web Scraper (around $50/month) provide user-friendly, visual interfaces. These tools are effective for simple data extraction tasks but can hit a wall when dealing with dynamic content loading or anti-bot mechanisms.
Interestingly, the web scraping market is expected to grow to $2.49 billion by 2032. This growth is fueling innovation, especially in AI-driven scrapers that can adapt to changing website structures without manual tweaks. But even with these advancements, scraping still comes with its fair share of challenges.
Solving Scraping Challenges
Modern websites, especially advertising platforms, are armed with advanced defenses to block scraping attempts. One of the biggest hurdles is CAPTCHAs, which often require manual intervention to bypass.
"We can bypass CAPTCHA while scraping by raising our trust score. In simple terms, we have to mimic the requests' configuration of normal human behavior on a web browser."
- Johann Saunier
Another common obstacle is infinite scroll, which is used by around 65% of e-commerce sites. While tools like Playwright can automate scrolling, they require custom coding to work effectively. Then there’s selector drift - when platforms update their structure, scrapers can start returning empty or incorrect data, forcing teams to constantly monitor and adjust their tools.
Additionally, proxy rotation is a must when scraping multiple platforms or large datasets. Without it, IP bans can bring your operations to a halt. To scrape successfully, you need a well-rounded approach that includes session management, behavior simulation that mimics real users, and the ability to adapt quickly to website changes.
InstantAPI.ai for Ad Data Collection
These challenges make it clear that a more automated and adaptable solution is needed.
That’s where InstantAPI.ai comes in. It removes the usual headaches of web scraping, like coding selectors or managing proxies. All you need to do is define a JSON schema, and the platform takes care of the rest. InstantAPI.ai handles over 1 million scrapes each month with a 99.99% success rate.

The 9 Best Ways to Scrape Any Website in N8N
Adding Scraped Data to Analytics Systems
Once you've extracted ad data using tools like InstantAPI.ai, the next step is preparing it for analytics. This involves cleaning, validating, automating collection processes, and ensuring compliance with U.S. regulations. Each step plays a vital role in maintaining the accuracy and reliability of your ad performance insights.
Cleaning and Validating Scraped Data
Raw scraped data often contains errors or inconsistencies. To ensure accurate analysis, you’ll need to clean and validate it. Start by removing duplicate entries, standardizing terminology (e.g., unifying terms like "CTR" and "Click-Through Rate"), and filtering out anomalies that could distort your results. Address missing data by filling in gaps, excluding incomplete records, or applying adjustments.
Validation is equally important. For example, ensure dates follow the MM/DD/YYYY format, monetary values include proper dollar signs and decimals (e.g., $1,234.56), and percentages stay within the 0–100% range. Range checks can catch unrealistic values, like negative clicks, while referential integrity rules confirm that campaign IDs in your data match those in your database.
Poor data management can lead to costly mistakes. Duplicate entries are common, as ad platforms may display the same campaign across different sections. Missing metrics are another issue, often caused by campaigns with low spending or temporary platform updates. By thoroughly cleaning and validating your data, you minimize these risks and ensure reliable insights.
API-Based Data Collection Automation
To streamline data collection, integrate InstantAPI.ai’s /scrape endpoint into your analytics workflow. Set up automated HTTP requests to handle extraction, transformation, and loading of data, ensuring consistent and clean JSON output. This automation eliminates the need for complex parsing and simplifies troubleshooting when issues arise.
Monitoring is key to maintaining automation. Set up alerts for unusual drops in data volume, uncategorized campaigns, or errors caused by platform changes. These notifications help you address problems quickly, preventing gaps in your analytics that could impact decision-making.
InstantAPI.ai’s pay-per-use model makes automation affordable, especially when monitoring multiple campaigns or market segments. At $2.00 per 1,000 pages, you only pay for what you use, avoiding unnecessary fixed costs. With automated data collection in place, the next priority is ensuring compliance with U.S. regulations.
US Regulatory Compliance for Ad Data
When collecting ad data in the U.S., compliance with laws like CCPA/CPRA, the FTC Act, TCPA, and COPPA is essential. Focus on gathering aggregate metrics, respect robots.txt files, and use official APIs whenever possible. Avoid scraping personal data without consent, and seek legal guidance to stay aligned with privacy laws.
While web scraping itself isn’t inherently illegal, processing certain types of data - like names, email addresses, or browsing histories - can trigger legal obligations. To reduce risks, prioritize collecting aggregate metrics such as impressions, click-through rates, and ad spend. If your scraping encounters personal data, ensure you have proper consent and document your legal basis for processing it.
Practical steps for compliance include adhering to rate limits and respecting robots.txt directives. Using official APIs when available not only reduces legal risks but also shows good faith in following platform policies. Additionally, consulting legal experts can help you navigate the evolving landscape of privacy regulations across different states, ensuring your ad data collection practices remain above board.

Next, examine call-to-action (CTA) strategies. Research shows personalized CTAs can boost conversions by 42%, so identifying effective CTAs in competitor campaigns can inform your own strategies.
Pay attention to ad placement and timing patterns. For instance, HubSpot often focuses its ads on LinkedIn to reach B2B professionals and decision-makers. Noticing shifts in ad frequency or messaging might hint at a competitor’s new product launch or market expansion.
Don’t overlook visual elements. Study the images, videos, and designs competitors use to reinforce their brand. For example, LinkedIn ads targeting recruiters often feature professional visuals paired with messages about efficient hiring and cost savings - content that resonates with their audience.
Consistent formatting is critical during analysis. Ensure dates, currency values, and percentages follow standardized formats (e.g., MM/DD/YYYY or $1,234.56). This consistency is essential when sharing insights or integrating data into analytics tools.
By analyzing these elements, you can uncover gaps in the market and identify strategies that resonate with your audience.

FAQs
How can web scraping be used to track online ad performance when APIs fall short?
Web scraping offers a practical way to collect ad performance data, especially when APIs are unavailable, overly restrictive, or come with high costs. Unlike APIs, which often impose usage limits or provide delayed updates, web scraping allows you to pull real-time data directly from websites. This approach makes it easier to keep tabs on metrics like ad placements, competitor campaigns, and performance trends.
One of the biggest advantages of web scraping is its ability to handle dynamic pages, infinite scroll, and larger datasets without being tied down by API restrictions. This means businesses can track ad performance more thoroughly and adjust their strategies based on timely, actionable data.
What legal factors should marketers consider when using web scraping to track ad performance?
Is Web Scraping Legal in the United States?
In the U.S., web scraping is typically allowed as long as you're gathering publicly available information that isn't protected by copyright, behind login barriers, or restricted by other access controls. However, it crosses into legal gray areas if it involves bypassing security measures, accessing confidential or proprietary data, or disregarding a website's terms of service.
To ensure you're on the right side of the law, it's essential to carefully review the terms of service for any site you intend to scrape. Avoid collecting any data that's sensitive or protected. And if you're uncertain about the legality of your approach, it's always wise to consult a legal professional to confirm your practices comply with current laws and regulations.
