Symbols & Numbers

+Keyword (Broad Match Modifier) was a keyword syntax that allowed you to lock specific words in a search query while leaving others flexible. It offered a perfect balance between reach and control until Google killed it to force more advertisers into broad match. You will still see old-timers mourning its loss in forums.

A

Absolute Top Impression Share measures the percentage of times your ad appeared as the very first result above the organic listings. It is a vanity metric for most, but a critical KPI for brand defense campaigns where you cannot afford to be second. If you aren’t hitting 90%+ here on your own brand name, you have a problem. 

Account-Level Negative Keywords allow you to block specific terms across every single campaign in your account at once. This is the most efficient way to prevent your budget from being wasted on obvious junk like “free,” “job,” or “scam” without managing hundreds of individual lists.

Actual CPC is the amount you actually pay for a click, which is usually one cent more than the rank of the advertiser below you. It is almost always lower than your Max CPC bid, assuming the auction is functioning correctly.

Ad Customizers allow you to dynamically inject price, countdowns, or inventory levels into your ad text based on the user’s context. They create a sense of urgency and relevance that static ads cannot match, usually resulting in a higher click-through rate.

Ad Rank is the hidden score that determines where your ad appears on the page. It is calculated by multiplying your bid by your Quality Score. If your Quality Score is terrible, you have to pay a significant premium just to show up.

Ad Rotation is a setting that determines which ad variation shows when you have multiple options in an ad group. Google strongly prefers “Optimize,” which lets their machine learning pick the winner, often before you have statistical significance. The “Rotate Indefinitely” option was removed to prevent you from testing manually.

Ad Schedule (Dayparting) allows you to adjust bids or turn off ads completely during specific hours or days. Use this if your data proves that clicks at 3 AM are fraudulent or if your sales team isn’t around to answer the phone.

Ad Strength is Google’s automated grading system for your creative, ranging from “Poor” to “Excellent.” It is largely a measure of how well you followed Google’s advice to add more headlines, not a prediction of actual conversion performance. You can often ignore it if your ROAS is healthy.

AdWords was the original name of the platform before it rebranded to Google Ads in 2018. If a consultant or agency still calls it “AdWords” in their sales pitch, their knowledge is likely about as current as the name.

Alpha / Beta Structure is an advanced campaign structure where you separate high-performing “Alpha” keywords into their own exact match campaigns with dedicated budgets. It minimizes waste and maximizes control over your top revenue drivers.

Assets (formerly Extensions) are additional pieces of information like phone numbers, sitelinks, or images that appear alongside your ad text. They increase the physical size of your ad on the screen, which generally improves click-through rates and Quality Score.

Attribution Model determines how credit for a conversion is assigned to the different clicks in a user’s journey. Google has deprecated first-click, linear, and time-decay models to force everyone into “Data-Driven Attribution,” which uses their black-box AI to assign value.

Audience Segments allow you to target or bid differently for groups of users based on their behavior, interests, or demographics. Layering these onto your search campaigns provides data on who is clicking, even if you don’t restrict your targeting to them.

Auction Insights is a report that shows who you are competing against and how often they outrank you. It is the only real look you get at your competitors’ activity and budget strength.

Automated Rules are simple “if this, then that” scripts you can set up to manage bids or budgets when you aren’t at your desk. They are useful for preventing budget blowouts over the weekend or pausing ads when inventory hits zero.

Auto-Apply Recommendations is a setting where Google automatically implements their suggestions to your account without your approval. You should turn this off immediately, as the suggestions prioritize Google’s revenue over your efficiency.

Average Position was a metric that told you exactly where your ad ranked on the page (e.g., 1.4 or 3.2). Google removed it in 2019 to obscure competition data, replacing it with the vague “Top” and “Absolute Top” impression share metrics.

B

Bid Strategy is the method you choose for how to pay for clicks, ranging from manual control to fully automated AI. Choosing the wrong one for your budget level—like using Target CPA with zero conversion history—is the fastest way to kill a campaign. 

Broad Match is the default match type that lets Google show your ad for any query it thinks is remotely related to your keyword. It is designed to maximize spend and requires a massive negative keyword list to be profitable.

Broad Match Modifier (BMM) (See +Keyword).

C

Call-Only Ads are mobile ads that initiate a phone call immediately upon clicking rather than visiting a website. They are effective for service businesses but expensive if you don’t have a team ready to answer the phone instantly. 

Change History is a log of every edit made to the account, including who made it and when. It is the first place you look when performance tanks overnight to see if someone broke the bidding strategy.

Click-Through Rate (CTR) is the percentage of people who see your ad and click on it. It is a primary factor in Quality Score; a low CTR usually implies your ad copy is boring or your targeting is wrong.

Close Variants are search queries that Google treats as identical to your keyword, including misspellings and synonyms. Google has aggressively expanded this definition, meaning “Exact Match” is no longer actually exact.

Conversion is the specific action you want a user to take, such as buying a product or filling out a form. If you are running ads without tracking conversions, you are just setting money on fire.

Conversion Action Sets allow you to group specific conversion goals for different campaigns. This ensures your lead generation campaigns optimize for form fills while your e-commerce campaigns optimize for purchases.

Conversion Rate is the percentage of clicks that result in a conversion. It is a measure of your landing page’s effectiveness, not your ad’s effectiveness.

Converted Clicks was an old metric that counted the number of unique clicks that led to one or more conversions. It was retired in 2016 in favor of simply counting “Conversions,” which can tally multiple actions per click.

Cost Per Acquisition (CPA) is the average amount you spend to get one conversion. This is your bottom-line efficiency metric for lead generation.

Cost Per Click (CPC) is the price you pay for a single visitor. It fluctuates based on competition, Quality Score, and your bid strategy.

Customer Match allows you to upload lists of email addresses or phone numbers to target existing customers or exclude them from campaigns. It is one of the highest-ROI targeting methods available because the intent is already verified.

D

Daily Budget is the amount you tell Google you are willing to spend per day, though they can legally exceed it by up to 100% on any given day. They claim it averages out over the month, but it makes cash flow management annoying. 

Data-Driven Attribution (DDA) is Google’s default attribution model that uses machine learning to assign credit to touchpoints. It requires a certain volume of data to work accurately; otherwise, it is just guessing.

Demand Gen Campaigns are the replacement for Discovery Ads, focused on visual placements across YouTube, Gmail, and the Discover feed. They are designed to create awareness rather than capture immediate intent.

Display Network (GDN) is a massive network of millions of websites where you can show banner ads. It is notoriously full of low-quality inventory and accidental clicks, so it requires aggressive exclusion lists.

Discovery Ads were a visual ad format that appeared in Google feeds. They have been sunset and rolled into Demand Gen campaigns.

Drafts & Experiments allow you to split-test changes to a campaign without risking the entire budget. You should use this for testing new bid strategies or landing pages before rolling them out completely.

Dynamic Search Ads (DSA) use your website’s content to automatically generate headlines and target search queries. They are excellent for capturing long-tail traffic you didn’t think to bid on, provided your SEO structure is solid.

E

Enhanced CPC (eCPC) is a semi-automated bid strategy that adjusts your manual bids up or down based on the likelihood of a conversion. It is a stepping stone between manual bidding and full automation. 

Exact Match is a keyword match type that targets specific queries and their close variants. It offers the tightest control over spend but has lost precision as Google expanded the definition of “close variant.”

Expanded Text Ads (ETA) were the standard ad format consisting of three headlines and two descriptions. Google discontinued the creation of new ETAs in 2022 to force advertisers into Responsive Search Ads (RSAs).

F

Final URL is the actual web address a user lands on after clicking your ad. It must match the domain of your Display URL, or your ad will be disapproved. 

First-Page Bid Estimate is Google’s prediction of what you need to bid to appear anywhere on the first page of results. If your max bid is below this, you are effectively invisible.

G

Google Ads Editor is a desktop application that allows you to make bulk changes to your accounts offline. It is an essential tool for professionals who need to manage large accounts without waiting for the slow web interface to load. 

Google Merchant Center is the platform where you upload your product feed for Shopping campaigns. If your data here is messy, your Shopping ads will fail regardless of your bid strategy.

Google Tag (gtag.js) is the code snippet required on your website to track conversions and build remarketing lists. Without it, you are flying blind.

H

Headline is the bold, blue text at the top of a search ad that catches the user’s attention. You have 30 characters to make a promise or solve a problem.

I

Impression is counted every time your ad is displayed on a screen. Impressions without clicks are just “brand awareness,” which doesn’t pay the bills. 

Impression Share is the percentage of eligible searches where your ad actually appeared. Losing impression share due to budget means you need to spend more; losing it due to rank means you need to improve quality or bids.

In-Market Audiences are groups of users who Google believes are actively researching or planning to buy a specific product. They are generally high-intent and good targets for prospecting.

Invalid Clicks are clicks that Google identifies as accidental or fraudulent (bots). Google filters these out and refunds the cost, though they often miss sophisticated click fraud.

K

Keyword Insertion is a feature that dynamically updates your ad text to include the user’s search query. It boosts relevance but can result in grammatically nonsensical ads if not configured carefully. 

Keyword Planner is Google’s internal tool for researching search volume and bid estimates. Take the volume numbers with a grain of salt, as they are often grouped broadly.

L

Landing Page Experience is a component of Quality Score that judges how relevant and user-friendly your site is. Sending traffic to a slow homepage instead of a specific product page will tank this score. 

Local Service Ads (LSA) are a separate ad unit for service providers like plumbers and lawyers that appear above standard search ads. They require a background check and verification from Google.

Location Intent determines whether you show ads to people physically in a location or just people interested in that location. The default setting targets both, which often wastes budget on irrelevant international traffic.

Lookalike Audiences (now “Similar Segments”) were groups of users who shared characteristics with your existing customers. Google sunsetted “Similar Audiences” in 2023, replacing them with “Optimized Targeting” and automated audience expansion.

M

Manual CPC is a bidding strategy where you set a static maximum price for every individual keyword. It offers the ultimate control but requires daily management to remain competitive. 

Maximize Clicks is an automated bid strategy designed to get as much traffic as possible within your budget. It ignores conversion quality, so it is often used for brand awareness or filling remarketing pools.

Maximize Conversions is a smart bidding strategy that spends your daily budget to get the highest quantity of conversions possible. It does not care about the cost per conversion, so it will happily spend $100 to sell a $50 item if you don’t set a target CPA.

Maximize Conversion Value is a smart bidding strategy that targets the highest total revenue. It is ideal for e-commerce but requires accurate revenue tracking to work.

N

Negative Keyword is a term you explicitly add to prevent your ads from showing. Managing these is 90% of the work in a successful search campaign. 

Negative Keyword List is a shared library of negative keywords that can be applied to multiple campaigns. It saves time and ensures consistent blocking of bad traffic across the account.

O

Optimization Score is a percentage score Google gives your account based on whether you have adopted their automated recommendations. It is a sales tool for Google, not a performance metric for you; do not obsess over getting it to 100%. 

Optimized Targeting is a setting in Display and Demand Gen campaigns that allows Google to find users beyond your selected audience signals. It is aggressive and often spends budget on low-quality traffic if not monitored.

P

Performance Max (PMax) is a “black box” campaign type that runs ads across all Google inventory (Search, Maps, YouTube, Display) from a single campaign. It offers very little data transparency but can drive high volume if you feed it good creative and audience signals. 

Phrase Match is a match type that targets queries including the meaning of your keyword, respecting the order when it matters. It has absorbed the functionality of the defunct Broad Match Modifier.

Placement is a specific website, app, or YouTube channel where your ad appears. In Display campaigns, you should review these regularly to exclude spammy mobile apps and kids’ YouTube channels.

Portfolio Bid Strategy allows you to group multiple campaigns under a single automated bidding goal. It is useful for aggregating data from smaller campaigns to help the AI learn faster.

Product Group is a subset of your inventory in a Shopping campaign that you bid on together. Granular product groups allow you to bid more aggressively on your best sellers.

Q

Quality Score is a diagnostic metric (1-10) that estimates the quality of your ads, keywords, and landing pages. A higher score lowers your cost per click.

R

Recommendation Tab is a section of the Google Ads interface that suggests changes to improve your Optimization Score. Most “recommendations” are just ways to increase your spend or broaden your targeting. 

Remarketing List for Search Ads (RLSA) allows you to target past website visitors when they search for keywords on Google. You can bid higher for these users because they are more likely to convert.

Responsive Display Ads (RDA) allow you to upload images and text assets that Google automatically combines to fit any ad slot size. They are efficient but offer zero control over the final visual design.

Responsive Search Ads (RSA) are the default search ad format where you provide up to 15 headlines and 4 descriptions, and Google mixes and matches them. They rely on machine learning to find the best combination for each user.

Return on Ad Spend (ROAS) is the revenue generated for every dollar spent on ads. It is the primary efficiency metric for e-commerce businesses.

S

Search Impression Share (See Impression Share). 

Search Partners are non-Google websites (like Ask.com or local directories) that use Google’s search engine to show ads. Traffic quality here is generally lower than https://www.google.com/search?q=Google.com, and you should segment your data to check if it’s wasting money.

Search Query Report (SQR) (now “Search Terms Report”) shows the actual terms users typed before clicking your ad. Mining this report for negative keywords is the most critical weekly task for a PPC manager.

Shopping Campaign is an ad campaign that displays product images and prices from your Merchant Center feed. It captures users with high purchase intent who want to see the product before clicking.

Single Keyword Ad Group (SKAG) was a strategy of putting one keyword in one ad group to maximize relevance. It is largely obsolete now that match types are looser and RSAs require more data to optimize.

Smart Bidding is the umbrella term for Google’s automated bid strategies (Target CPA, Target ROAS, etc.) that use machine learning to set bids at auction time. It beats manual bidding in most accounts that have sufficient conversion data.

Smart Campaigns are simplified, automated campaigns designed for small businesses with no marketing experience. They offer almost no control or data and should be avoided if you are serious about performance.

T

Target CPA (tCPA) is a bid strategy where you set a desired cost per conversion, and Google adjusts bids to hit that average. It is the standard for lead generation. 

Target Impression Share is a bid strategy that automatically sets bids to ensure your ad appears at the top of the page a specific percentage of the time. It is useful for brand terms but can get very expensive very quickly.

Target ROAS (tROAS) is a bid strategy where you tell Google the return you need (e.g., 400%), and it bids accordingly. It requires consistent conversion value data to function.

U

Universal App Campaign (UAC) (now just “App Campaigns”) is an automated campaign type for promoting mobile app installs. You provide the creative and the budget, and Google finds the users across Play, Search, and YouTube. 

V

View-Through Conversion counts users who saw your ad, did not click, but converted later. It is useful for measuring the impact of Display and Video ads, but easy to overvalue.

Y

YouTube Ads are video advertisements served on YouTube, managed through the Google Ads interface. They are powerful for branding but traditionally harder to convert directly than Search.
