Google Ads Glossary
Every Google Ads term defined in plain English. Bookmark this page — your complete reference for understanding PPC, bidding, targeting, and performance metrics.
A
Ad Auction
The real-time process Google runs every time a user searches a keyword to determine which ads appear and in what order. Your ad rank determines placement — not just your bid, but your Quality Score too.
See how we win auctions for home services →Ad Extensions (Ad Assets)
Additional information added to your Google Ad — call buttons, site links, location, promotions, callouts. Extensions increase real estate and improve CTR by 10–20% on average.
Ad Rank
Google’s score that determines your ad position. Calculated by: Bid × Quality Score × Expected Impact of Extensions. A higher Quality Score lets you outrank competitors with lower bids.
Ad Schedule (Dayparting)
Setting specific hours or days for your ads to run. Critical for service businesses — if your phones aren’t answered at 2am, you shouldn’t be paying for clicks at 2am.
Audience Segments
Groups of users defined by behavior, demographics, or intent. In-market audiences (actively researching your service) typically convert at 2–3x the rate of general audiences.
B
Bid Strategy
How Google automatically adjusts your bids. Options include: Target CPA (cost per acquisition), Target ROAS, Maximize Conversions, Maximize Clicks, and Manual CPC. Choosing the wrong strategy is one of the top reasons accounts underperform.
Learn our bid strategy approach →Broad Match
A keyword match type that shows your ad for searches related to your keyword, including synonyms and related terms. Highest reach but lowest precision. Requires robust negative keyword lists to avoid wasted spend.
Budget (Daily Budget)
The average amount you’re willing to spend per day on a campaign. Google may spend up to 2x your daily budget on some days but averages out over the month. Set at campaign level in Google Ads.
C
Call-Only Ads
Google Ads designed exclusively to generate phone calls — no landing page required. Ideal for HVAC, legal, and medical businesses where a phone call = a qualified lead. Typically 30–50% lower CPL for service industries.
See our call-only ad strategy →Click-Through Rate (CTR)
The percentage of people who click your ad after seeing it. Formula: Clicks / Impressions × 100. Industry average search CTR is 4–6%. A low CTR signals weak ad copy or poor keyword/intent alignment.
Conversion Rate (CVR)
The percentage of ad clicks that result in a conversion (call, form fill, purchase). Formula: Conversions / Clicks × 100. The single most important lever for improving ROI without increasing budget.
Conversion Tracking
The system that records when a user completes a desired action after clicking your ad. Without it, Google’s Smart Bidding algorithms have no data to optimize toward — making optimization nearly impossible.
Cost Per Acquisition (CPA)
The total cost to acquire one customer or conversion. Formula: Total Ad Spend / Total Conversions. Target CPA bidding tells Google your desired CPA and lets it automatically adjust bids to hit that goal.
Cost Per Click (CPC)
The amount you pay each time someone clicks your ad. Varies wildly by industry — from $1–3 for pet services to $15–50 for legal keywords. Your actual CPC is determined by the ad auction, not just your max bid.
Cost Per Lead (CPL)
Total ad spend divided by number of leads generated. The most common KPI for service businesses. CPL = Budget / Leads. Reducing CPL while maintaining lead quality is the core of what RYN does for clients.
See our CPL reduction case studies →D
Display Network (GDN)
Google’s network of 2M+ websites and apps where your image/banner ads can appear. Best for brand awareness and retargeting. Generally lower conversion rates than Search but much lower CPCs.
Dynamic Search Ads (DSA)
Ads where Google automatically generates headlines based on your website content. Good for large websites with many pages. Requires careful negative keyword management to avoid irrelevant matches.
E
Exact Match
A keyword match type that shows your ad only for searches that exactly match (or are very close variants of) your keyword. Highest precision, lowest volume. Ideal for high-value, high-intent keywords.
Enhanced CPC (ECPC)
A semi-automated bid strategy where Google adjusts your manual bids up or down based on conversion likelihood. A stepping stone between full manual and fully automated Smart Bidding.
F
Frequency Cap
A Display and YouTube setting that limits how many times one user sees your ad. Essential for retargeting campaigns to avoid ad fatigue and negative brand perception from over-exposure.
G
Geo-Targeting (Location Targeting)
Restricting your ads to specific geographic areas — cities, zip codes, radius around an address. Critical for local service businesses. Radius bidding (higher bids closer to your location) can dramatically improve lead quality.
Google Analytics (GA4)
Google’s free web analytics platform. Linking GA4 with Google Ads enables richer audience data, cross-channel attribution, and deeper conversion insights beyond what the Ads platform shows alone.
Google Partner
A designation for agencies that meet Google’s performance, spend, and certification requirements. Partners receive direct Google support, beta features, and training resources. RYN Digital is a certified Google Ads partner.
I
Impression Share
The percentage of eligible impressions your ads actually received. Lost impression share due to budget means you’re running out of money. Lost due to rank means your Quality Score or bids are too low. Both are fixable.
In-Market Audiences
Users Google has identified as actively researching a product or service category. Using in-market audience targeting as bid modifiers can reduce CPL by 20–40% for service businesses.
K
Keyword Intent
The underlying goal of a search query. Transactional intent (“hvac repair near me”) converts far better than informational intent (“how does hvac work”). Building campaigns around high-intent keywords is foundational to RYN’s strategy.
See our keyword strategy for home services →L
Landing Page
The web page a user arrives on after clicking your ad. Arguably more important than the ad itself — a weak landing page wastes every dollar you spend. Speed, clarity, social proof, and a single CTA are the pillars of a high-converting page.
Local Service Ads (LSA)
Google’s pay-per-lead product for local service providers. Ads appear above traditional PPC ads with a “Google Guaranteed” badge. You only pay when a customer contacts you directly. Powerful for HVAC, legal, and healthcare.
See our LSA strategy →M
Match Types
Controls how closely a search query must match your keyword to trigger your ad. The three types are: Broad Match (widest reach), Phrase Match (moderate control), and Exact Match (highest precision). Using the right mix is critical for budget efficiency.
Maximize Conversions
A Smart Bidding strategy where Google automatically sets bids to get the most conversions within your budget. Best used when you have at least 30–50 conversions per month for the algorithm to learn from.
N
Negative Keywords
Keywords that prevent your ad from showing on irrelevant searches. The most underutilized tool in Google Ads. A comprehensive negative keyword list can reduce wasted spend by 20–40% immediately.
Learn why negatives matter for HVAC →P
Performance Max (PMax)
Google’s newest campaign type that uses AI to serve ads across all Google channels — Search, Display, YouTube, Gmail, Maps. Powerful but requires quality creative assets and solid conversion tracking to perform well.
Phrase Match
Shows your ad for searches that include the meaning of your keyword. Middle ground between Broad and Exact. A good default for most campaigns — captures intent variations without the noise of Broad Match.
PPC (Pay-Per-Click)
An advertising model where you pay each time someone clicks your ad. Google Ads is the world’s largest PPC platform. PPC is typically the fastest way to generate leads for local service businesses — results in days, not months.
Q
Quality Score
Google’s 1–10 rating of your keyword’s relevance and expected CTR. Higher Quality Scores = lower CPCs and better ad positions. Three components: Expected CTR, Ad Relevance, Landing Page Experience. Improving QS is one of the highest-ROI optimizations available.
R
Remarketing / Retargeting
Showing ads to users who previously visited your website. Remarketing audiences convert at 2–5x the rate of cold audiences and typically cost 50–70% less per conversion. Essential for any campaign with significant traffic.
Responsive Search Ads (RSA)
The current standard Google Ads text ad format. You provide up to 15 headlines and 4 descriptions; Google tests combinations and auto-optimizes toward the best performers. Use keyword pinning strategically for maximum control.
ROAS (Return on Ad Spend)
Revenue generated per dollar spent on ads. Formula: Revenue / Ad Spend. A 3x ROAS means $3 earned for every $1 spent. Target ROAS bidding automates bids to hit a specific ROAS goal — requires solid revenue tracking to work correctly.
Calculate your potential ROAS →S
Search Impression Share (SIS)
The percentage of Search impressions you received out of all eligible impressions. SIS below 50% means you’re missing half your potential traffic. Target 70%+ SIS for core branded and high-intent keywords.
Search Network
Google.com and its search partner sites. Where text ads appear in response to active searches. The Search Network drives the highest-intent traffic available in digital advertising — users are actively looking for what you offer.
Smart Bidding
Automated bid strategies that use Google’s machine learning — Target CPA, Target ROAS, Maximize Conversions, Maximize Conversion Value. Outperforms manual bidding when sufficient conversion data exists (30+ conversions/month).
T
Target CPA (tCPA)
A Smart Bidding strategy where you set a target cost per conversion and Google automatically adjusts bids to meet it. Most effective when you have 50+ conversions/month. Under-conversion accounts should start with Maximize Conversions first.
Target ROAS (tROAS)
Tells Google to optimize bids toward a specific return on ad spend. Ideal for ecommerce or high-ticket services where revenue values vary significantly. Requires revenue conversion tracking (not just lead tracking) to function correctly.
V
View-Through Conversion
A conversion that occurs after a user saw (but didn’t click) your Display or YouTube ad, then later converted on your site. Indicates brand awareness impact but should be interpreted cautiously — often over-counted.
W
Wasted Spend / Search Terms Report
The Search Terms Report shows exactly what users typed before clicking your ad. Reviewing it weekly reveals irrelevant triggers to add as negative keywords. Most unmanaged accounts waste 25–40% of budget on irrelevant searches.
