We sat down with an SEA expert to explore what data really matters and how to interpret it in the context of business growth.
When it comes to Search Engine Advertising (SEA), not all data is equally valuable. If you're running Google Ads or another paid campaign, it's tempting to focus on easy-to-access metrics like clicks and impressions. But to measure success meaningfully, especially in the SaaS world, you need to look deeper.
So what should you measure? Below are the most important metrics and what they actually tell you:
| Metric | Meaning | Ideal Scenario |
| Impressions | How many times has it been seen |
High impressions with relevant audience exposure |
| CTR | How many clicks per impression |
High CTR resulting in quality clicks |
| Conversion Rate | How many clicks became conversions | High conversion rate with relevant conversions |
| Lead Quality (MQL/SQL) | How valuable your leads are | A High percentage of MQLs become SQLs |
| Acquisition Cost (AC) | How much you pay per customer | Low cost per quality lead/customer |
| Funnel Progression | How leads move through your funnel | Predictable progression and sales |
The key is to avoid vanity metrics and focus on relevance.
Vanity metrics are numbers that look impressive but don't actually correlate with core business growth. Think of high impression counts that generate no sales as an example; it is a number that looks pretty and promising, but doesn't have an output.
Launching a SEA campaign is just the beginning. Whether your ads are running smoothly or need tweaks, most marketers check their ad dashboard daily, but very few know what to look for.
The moment your ad goes live, you’re flooded with numbers. But rather than obsessing over sheer volume, focus on relevance. It's not just about being visible, it’s about being visible to the right audience, at the right moment.
High impression counts might make you feel like your ad is performing, but without a solid Click-Through Rate (CTR), they’re meaningless.
One important metric that should always be taken into account when looking at impressions is the CTR, which tells you how often people actually click when they see your ad.
CTR = (Clicks / Impressions) × 100
A high CTR indicates:
Your ad matches user intent.
Your copy and creative are compelling.
You’re targeting the right keywords.
In turn, a high CTR without conversions can be dangerous. It may mean you’re paying for irrelevant traffic. That’s why CTR should always be interpreted alongside post-click data.
Clicks are only useful if they lead to meaningful actions. In SaaS, this often means trial signups, demo requests, or newsletter subscriptions. But even those conversions don’t tell the full story. You need to assess conversion quality.
Conversion Rate = (Conversions / Clicks) × 100
Let’s say your ad brings in 200 clicks and 40 demo requests: a 20% conversion rate. Good on paper. But if only 5 of those demos come from your target market, the real value of that traffic is low.
What to look for instead:
Are conversions aligned with your Ideal Customer Profile (ICP)?
Are leads completing meaningful actions (e.g., attending a demo, starting a trial)?
Are they moving further down your funnel?
In SaaS, not all conversions are created equal; your goal should be to focus on qualified leads. That's where Marketing Qualified Leads (MQLs), Sales Qualified Leads (SQLs), and Sales Opportunities come into play. SEA shouldn’t just generate conversions; it should fuel your funnel.
"A demo request is not a win. A qualified lead that fits your ICP, engages with your content, and converts to a sale: that’s a win."
Understanding lead quality means tracking lead behaviour after the click:
Do they engage with your emails or attend webinars?
Are they exploring your pricing page?
Are they located in target regions or verticals?
Only when leads progress through these steps can you truly say your SEA campaign is successful.
Your SEA strategy must align with your entire sales funnel. Each element, from creative to landing page to follow-up, plays a role in conversion and qualification. A strong SEA campaign supports every funnel stage:
Ad relevance → Clicks from the right audience
Landing page clarity → Higher conversion rates
Lead qualification → More MQLs and SQLs
Sales alignment → Faster close rates and higher CAC efficiency
If your SEA efforts don’t support your full funnel, you’re just throwing money at clicks.
SEA is powerful but only if measured meaningfully. If you obsess over surface metrics, you’ll miss the signals that truly indicate growth. Focus on the full journey from impression to revenue.
"It’s not about how many clicks you get. It’s about how many become customers and how efficiently they get there."
