Reference
Every term you need to understand your Google Ads performance. Written for SaaS teams, not PPC nerds.
Ad Group
A set of related keywords and ads inside a campaign. Think of it as a folder that groups ads targeting similar searches. In SaaS, you'd typically have separate ad groups for different features or use cases.
Ad Rank
Google's score that determines where your ad shows up. It's based on your bid, ad quality, and expected impact of assets. Higher Ad Rank = higher position on the page.
Bid Strategy
How you tell Google to spend your money. Manual CPC means you set every bid. Smart Bidding (like Target CPA or Target ROAS) lets Google's algorithm adjust bids automatically based on conversion data. For SaaS, Smart Bidding works best once you have 30+ conversions per month.
Broad Match
The loosest keyword match type. Google shows your ad for searches it considers "related" to your keyword. Dangerous in SaaS -- "project management software" can match "how to manage my time." Use with caution and strong negative keyword lists.
CAC (Customer Acquisition Cost)
The total cost to acquire one paying customer. Includes ad spend, agency fees, sales team cost -- everything. Not the same as CPA. Your Google Ads dashboard won't show you this number. You have to calculate it yourself.
Example: Rule of thumb: your CAC should be at most 1/3 of your LTV.
CPA (Cost Per Acquisition)
What Google Ads shows you as the cost per "conversion." If your conversion is a demo request, your CPA is the cost per demo. CPA is a Google Ads metric. CAC is a business metric. A €50 CPA on demos doesn't mean your CAC is €50 -- because not every demo becomes a customer, and there are costs beyond ad spend.
Click-Through Rate (CTR)
Percentage of people who see your ad and click it. A high CTR means your ad copy resonates. But CTR alone means nothing -- a 5% CTR on garbage traffic is worse than a 1% CTR on qualified buyers.
Conversion
Any action you define as valuable. In SaaS, this could be a demo request, free trial signup, or purchase. The problem: most SaaS companies set the wrong action as their conversion. A form fill is not a customer.
Conversion Rate
Percentage of clicks that become conversions.
Example: SaaS benchmarks: 2-5% for landing pages, higher for brand searches, lower for competitive keywords.
CPC (Cost Per Click)
What you pay each time someone clicks your ad. SaaS B2B keywords typically range from €2-€8. High CPC isn't bad if those clicks become customers.
CRM (Customer Relationship Management)
Software that tracks your leads and deals (HubSpot, Salesforce, Pipedrive). Critical for SaaS PPC because connecting your CRM to Google Ads enables offline conversion tracking -- the single most impactful thing you can do.
Display Network
Google's network of 2M+ websites where your ads can appear as banners. Mostly low-intent traffic for SaaS. Useful for retargeting, dangerous for prospecting.
Exact Match
The tightest keyword match type. Your ad only shows when someone searches for your exact keyword (or very close variants). More expensive per click, but much higher conversion rates. The default choice for high-intent SaaS keywords.
GCLID (Google Click ID)
A unique ID Google attaches to every ad click. This is how offline conversions work -- your CRM stores the GCLID, and when a lead becomes a customer, you send the GCLID back to Google so it knows which click generated revenue.
Impression
One instance of your ad being shown. Means nothing by itself. You can have a million impressions and zero customers.
Impression Share
Percentage of total available impressions your ad captured. If your impression share is 40%, you're missing 60% of potential searches.
Example: Low impression share usually means your budget or bids are too low.
Keyword
The word or phrase you bid on to trigger your ad. In SaaS, high-intent keywords include "[category] software," "[competitor] alternative," and "[category] for [use case]."
Landing Page
The page someone sees after clicking your ad. Not your homepage. A dedicated page that matches the ad's promise and has one clear CTA. Bad landing pages kill even the best campaigns.
LTV (Lifetime Value)
Total revenue you expect from a customer over their entire relationship with you.
Example: A SaaS customer paying €500/month who stays 24 months has an LTV of €12,000. Your CAC should be at most 1/3 of your LTV.
Negative Keywords
Words you tell Google to NOT show your ads for. Essential in SaaS: "free," "jobs," "salary," "tutorial," "login," "open source." Without negatives, you're paying for clicks from people who will never buy.
Example: Check your search terms report weekly and add new negatives.
Offline Conversion
A conversion that happens outside your website -- in your CRM. When a lead books a demo (on your site) and becomes a paying customer (in your CRM) 30 days later, that's an offline conversion. Importing these into Google Ads is the most underused lever in SaaS PPC.
Performance Max (PMax)
Google's AI-driven campaign type that runs ads across Search, Display, YouTube, Gmail, and Discover simultaneously. Powerful with enough data (50+ monthly conversions) and CRM tracking. A budget black hole without it.
Phrase Match
Middle-ground keyword match type. Your ad shows when someone's search includes your keyword in order, with words before or after.
Example: "project management software" matches "best project management software for teams." Good balance of reach and control.
Pipeline
In SaaS sales, the total value of deals in progress. Google Ads should be measured by pipeline generated, not leads generated.
Example: A €100K pipeline from €10K in ads is a 10x return.
Quality Score
Google's 1-10 rating of your keyword + ad + landing page relevance. Higher Quality Score = lower CPC and better ad position. Improve it by matching your ad copy to your keywords and your landing page to your ad.
Remarketing (Retargeting)
Showing ads to people who already visited your website. In SaaS, this is critical because buyers research for weeks before deciding. Remarketing keeps you visible during their consideration period.
Example: Usually the highest-ROI campaign in any SaaS account.
ROAS (Return on Ad Spend)
Revenue generated divided by ad spend. For SaaS, measure ROAS on actual closed revenue, not lead value.
Example: You spend €10K and generate €30K in revenue -> ROAS is 3x.
RSA (Responsive Search Ad)
Google's default search ad format. You provide up to 15 headlines and 4 descriptions, and Google's algorithm tests combinations.
Example: Best practice: include your main keyword in at least 3 headlines and your CTA in at least 2.
Search Terms Report
The actual queries people typed before clicking your ad. Different from keywords -- keywords are what you bid on, search terms are what people actually searched. Review weekly to find wasted spend and add negative keywords.
Smart Bidding
Google's automated bidding strategies that use machine learning. Includes Target CPA, Target ROAS, Maximize Conversions, and Maximize Conversion Value.
Example: Garbage in, garbage out -- if you're tracking the wrong conversions, Smart Bidding optimizes for the wrong thing.
SQL (Sales Qualified Lead)
A lead your sales team has qualified as worth pursuing. This is what you should optimize for in sales-led SaaS, not MQLs or form fills. If Google Ads doesn't know what an SQL looks like, it can't find more of them.
Target CPA (tCPA)
A Smart Bidding strategy where you tell Google your target cost per conversion. Google adjusts bids to hit that target on average.
Example: Works best with 30+ conversions per month and accurate conversion tracking.
Target ROAS (tROAS)
A Smart Bidding strategy where you set your target return on ad spend. Requires value-based conversion tracking -- each conversion must have a monetary value attached. The most sophisticated bidding strategy for SaaS.
