1st Party Data

Information collected directly from your audience or customers, including data from behaviors, actions, or interests demonstrated across your website or app. This data is crucial for PPC advertisers to understand their audience, personalize ads, and improve targeting for better campaign performance.

3rd Party Data

Data purchased or acquired from outside sources that did not have a direct relationship with the user it's being collected from. In PPC, this data is used to augment audience targeting and improve ad relevance by incorporating broader insights on consumer behaviors and preferences.


While not a traditional PPC term, hashtags are used in social media advertising to increase the discoverability of posts or ads. By including relevant hashtags, advertisers can reach a wider audience interested in specific topics, trends, or conversations, enhancing engagement and campaign reach.


Ad Auction

An automated process that determines the relevance and validity of ads to be displayed in response to a user's search query.

Ad Ad Copy

The text portion of a PPC ad that aims to capture the attention of the target audience and persuade them to take a desired action. Effective ad copy is crucial for high campaign performance, as it directly influences click-through rates (CTR), quality score, and overall conversion rates.

Ad Extensions

Additional information added to Google Ads, such as phone numbers, links to specific parts of a website, or user reviews, designed to enhance the ad's usefulness.

Ad Group

A collection of related ads within a campaign that share common targets and themes.

Ad Rank

A value that determines the position of an ad on a search engine results page (SERP), based on the ad's bid amount and quality score.


Bid Adjustment

A feature in PPC campaigns that allows advertisers to increase or decrease their bid amounts based on specific criteria, such as device type, location, time of day, or audience characteristics. Bid adjustments help optimize ad spend by targeting more aggressively in scenarios where conversions are more likely and saving budget in less favorable conditions.

Bid Strategy

The approach selected for setting bids on ad campaigns, which can range from manual bidding to various forms of automated bidding.


Click Fraud

The practice of repeatedly clicking on a PPC ad to artificially inflate traffic numbers or deplete a competitor’s advertising budget. Click fraud is a significant concern for advertisers, as it can lead to wasted ad spend and skewed campaign data. Various tools and strategies are employed to detect and prevent click fraud.

Click-Through Rate (CTR)

A metric that measures the number of clicks advertisers receive on their ads per number of impressions.

Conversion Rate

The percentage of users who take a desired action (like making a purchase) after clicking on an ad.

Conversion Tracking

The process of monitoring and recording actions taken by visitors after clicking on your ad. These actions, defined as conversions, can include making a purchase, signing up for a newsletter, or filling out a contact form. Conversion tracking is vital for understanding the effectiveness of PPC campaigns and for optimizing towards specific marketing goals.

Cost Per Click (CPC)

The cost incurred each time a user clicks on an ad.


Display Ads

Visual-based ads (including images and videos) displayed on networks of websites, not search engine results pages.

Dynamic Search Ads (DSA)

A type of ad in Google Ads that automatically generates ad headlines and landing pages based on the content of a website. DSAs are useful for capturing traffic on searches that are not covered by existing keywords, offering a way to fill in the gaps of keyword-based campaigns.


Engagement Metrics

Data that indicates how users interact with a website, including metrics like time on site, pages per session, and bounce rate. High engagement metrics can signal to search engines that a website provides valuable content and a positive user experience.

External Links

Hyperlinks that point from one domain to an entirely separate domain. These are used to provide readers with additional information or to cite sources. While external links can enrich content quality, their relevance and the authority of the linked domains can also influence a site's SEO.


Frequency Capping

A feature in PPC advertising that limits the number of times an ad is shown to the same user over a specific period. This prevents ad fatigue, ensuring that ads remain effective and do not overwhelm or annoy potential customers. Frequency capping helps advertisers maintain a balance between visibility and user experience, optimizing the impact of their ad campaigns.



The practice of delivering ads to users based on their geographic location. Geo-targeting allows advertisers to tailor their messaging and offers to local audiences, improving relevance and the effectiveness of ad campaigns. This is particularly useful for businesses with physical locations or those serving specific areas.


Geofencing is a location-based digital marketing strategy that involves setting up virtual boundaries or "fences" around a specific geographic area using GPS or RFID technology. When a mobile device enters or exits this predefined area, it triggers an action, such as sending a push notification, displaying targeted advertisements, or collecting data for analytics purposes.

Geofencing is used by businesses to engage with potential customers in real-time, based on their physical location. This strategy is particularly effective for local advertising, promoting in-store events, or offering location-specific discounts. It allows businesses to create highly personalized and contextually relevant marketing messages, enhancing the customer experience and increasing the likelihood of conversion.

In the context of PPC and digital advertising, geofencing can be used to tailor ad campaigns to users within a certain vicinity, making ads more relevant and timely. This precision targeting helps maximize the impact of ad spend by focusing on users most likely to respond positively based on their location.

Google Analytics

A powerful web analytics service offered by Google that tracks and reports website traffic. It's an indispensable tool for PPC advertisers, providing detailed insights into user behavior, campaign performance, and the effectiveness of their advertising efforts. By integrating Google Analytics with PPC campaigns, advertisers can track conversions, understand how users interact with their website after clicking on an ad, and measure the return on investment (ROI) of their advertising spend. Through its comprehensive reporting features, Google Analytics allows advertisers to analyze the paths users take to complete a conversion, identify which ads and keywords are driving the most valuable traffic, and optimize their campaigns for better performance. This data-driven approach helps in refining targeting strategies, improving ad copy, and ultimately, achieving better alignment with business goals. Google Analytics is essential for PPC success, as it offers the insights needed to make informed decisions and maximize the impact of digital advertising campaigns.


Impression Share

The percentage of impressions that your ads receive compared to the total number of impressions that your ads could get. Impression share is a crucial metric in PPC advertising, helping advertisers understand their visibility in comparison to competitors. It is calculated by dividing the number of impressions received by the total eligible impressions in the market. A high impression share indicates strong ad visibility, while a low impression share suggests there's room for improvement in campaign settings, bid strategies, or ad relevance.

Interest Targeting

A method in PPC advertising that allows advertisers to target users based on their interests, hobbies, and past interactions with certain types of content. This targeting option uses data from users' browsing history, app usage, and interactions on social media platforms to show ads that are more likely to be relevant to their interests. By leveraging interest targeting, advertisers can reach a more specific audience that is likely to be interested in their products or services, resulting in higher engagement rates and potentially higher conversion rates.



A word or phrase that a user enters into a search engine, which advertisers can target to display their ads.

Keyword Density

The percentage of times a keyword or phrase appears on a web page compared to the total number of words on the page. Over-optimizing can lead to penalties for keyword stuffing, whereas a balanced approach can improve a page's SEO.

Keyword Research

The process of finding and analyzing actual search terms that people enter into search engines. The insight from keyword research can inform content strategy and help websites align with user intent.


Landing Page

The webpage users are directed to after clicking on an ad.

Landing Page Optimization (LPO)

The process of improving elements on a website to increase conversions. In the context of PPC, LPO focuses on enhancing the pages that users land on after clicking an ad. This includes optimizing the content, design, call-to-action (CTA) buttons, and user experience to align with the expectations set by the ad, thereby improving the chances of converting visitors into customers.

Local SEO

Optimizing a website to increase traffic, leads, and brand awareness from local searches. Common tasks include claiming a business listing, managing local reviews, and optimizing a site's content for local search phrases.


Manual Bidding

A bid strategy in PPC advertising where the advertiser sets bid amounts for different keywords or ad placements manually, rather than relying on the advertising platform's automated systems. Manual bidding gives advertisers granular control over their bid amounts, allowing them to allocate budget based on their assessment of the value of each click. While it requires more time and attention, manual bidding can be highly effective in optimizing campaign performance, especially in campaigns where the advertiser has deep insights into the value of different keywords or audiences.

Match Types

In PPC advertising, match types determine how closely a user’s search query must match an advertiser’s keyword for the ad to be considered for the auction. The main types of keyword match options include broad match, phrase match, and exact match. Each match type offers different levels of control over who sees your ad:

Broad Match: The default match type that reaches the widest audience. Ads may show on searches that include misspellings, synonyms, related searches, and other relevant variations.

  • Phrase Match: Ads show on searches that include the meaning of your keyword, providing more control than broad match.
  • Exact Match: Ads show on searches that match the exact term or are close variations of that exact term, offering the highest level of control.

Understanding and effectively using match types can significantly impact the reach and effectiveness of PPC campaigns, allowing advertisers to fine-tune their targeting for better results.


Negative Keywords

Words or phrases added to a PPC campaign to prevent ads from being triggered by certain search queries. Negative keywords help refine targeting, reduce wasted spend, and increase campaign relevance by ensuring ads are shown only to users interested in the specific services or products being advertised.


Optimization Score

A metric used in PPC platforms like Google Ads that estimates how well your advertising campaigns are set to perform. Expressed as a percentage, the optimization score ranges from 0% to 100%, with a higher score suggesting that a campaign is more likely to achieve its objectives based on Google's recommendations. This score offers insights into potential improvements across bids, keywords, and ad creatives, guiding advertisers on how to optimize their campaigns for better performance.


Pay Per Click (PPC)

An advertising model where advertisers pay each time a user clicks on one of their online ads.


Quality Score

A metric used by Google Ads and other PPC platforms to evaluate the quality and relevance of your keywords and PPC ads. It influences your ads' positions on the SERP and the cost per click (CPC). Factors affecting Quality Score include the relevance of each keyword to its ad group, landing page quality, and the click-through rate (CTR) of the ad itself.



A strategy that shows ads to users who have previously visited your website, as they browse other websites within the display network.

Remarketing Lists for Search Ads (RLSA)

A Google Ads feature that allows advertisers to customize their search campaigns for users who have previously visited their website. This strategy enables advertisers to tailor their bids and ads when these past visitors search on Google, using keywords related to the products or services offered by the advertiser. RLSA can significantly enhance the effectiveness of search campaigns by focusing on an audience already familiar with the brand, thereby increasing the likelihood of conversion.

RLSA campaigns work by segmenting website visitors into lists based on their browsing behavior, which advertisers can then use to adjust their search advertising strategies. For example, an advertiser could increase bids for users who have visited their site but did not make a purchase, or show different ads to users based on the specific pages they visited. This approach allows for a more personalized and targeted advertising experience, optimizing ad spend by concentrating efforts on users who have shown a high intent to purchase.

The use of RLSA is a powerful tactic in PPC advertising, bridging the gap between user interest and action. By leveraging past interactions with their site, advertisers can create highly relevant ads that meet the specific needs and interests of their audience, improving overall campaign performance and ROI. This strategy not only re-engages potential customers but also provides a customized experience that can lead to increased brand loyalty and higher conversion rates.



Search Ad

Text-based ads displayed on search engine results pages in response to a user's search query.

Search Engine Marketing (SEM)

A form of Internet marketing that involves promoting websites by increasing their visibility in search engine results pages primarily through paid advertising.


Targeting Options

The settings that allow advertisers to show their ads to specific audiences based on various criteria like demographics, interests, and behaviors.


URL Tracking Parameters

Parameters added to the end of a URL to track the effectiveness of PPC campaigns across different platforms. These parameters can provide detailed information about how users interact with your ads, including which campaign, medium, or keyword drove them to your website. URL tracking parameters are essential for understanding the ROI of your PPC campaigns and for making data-driven decisions to optimize performance.


Vanity URL

A URL that is designed to be easy to remember and read. Vanity URLs are often a branded short link that redirects to a longer URL. They're used for marketing purposes because they're more memorable for users and can improve click-through rates. Vanity URLs can also be used to track the effectiveness of various marketing campaigns or platforms.


Wasted Spend

A term in PPC advertising that refers to money spent on clicks that do not convert into desired outcomes, such as sales or leads. Wasted spend indicates inefficiencies in a PPC campaign, often resulting from broad keyword targeting, poorly crafted ads, or irrelevant landing pages. Identifying and minimizing wasted spend is crucial for optimizing campaign ROI, involving strategies like refining keyword match types, improving ad relevance, and enhancing landing page experiences to better match user intent.


X-device Tracking

In PPC advertising, x-device tracking refers to the ability to track user interactions with ads across multiple devices, such as smartphones, tablets, and desktop computers. This tracking provides a cohesive view of how individual users engage with ads, regardless of the device they use. Understanding cross-device behavior is crucial for optimizing PPC campaigns, as it allows advertisers to attribute conversions accurately and tailor their strategies to reach audiences more effectively across their device usage patterns.
