The history of Google Ads can be summarized in one word: evolution. From its humble(ish) beginnings in 2000, the platform has become a force to be reckoned with. It relentlessly revolutionizes how businesses engage with their target audience, unlocking remarkable opportunities for connection and growth.

Understanding the evolution of Google Ads is immensely helpful for modern marketers, as it offers valuable insights into the platform’s development and the shifting landscape of online advertising and how even the giants of Google have had to adapt. The platform has been forced to adapt to technological advancements and user behavior, such as the rise of mobile devices, the proliferation of data-driven targeting, the increasing emphasis on user experience, and, most recently, the introduction of artificial intelligence. 

This knowledge empowers marketers to level up their advertising game, harness new tools and ad formats, and stay one step ahead of the competition in the cutthroat world of digital advertising.

Let’s look at some of the biggest moments in Google Ad’s evolution from 2000 to 2023.

The Google Ads Timeline

October 2000 – Google Introduces Ads

The introduction of ads by Google in 2000 marked the beginning of the search engine’s foray into the world of online advertising. It provided businesses a platform to promote their products and services through text-based ads and search results. This development laid the foundation for the advertising platform, setting the stage for enormous advancements to come.

December 2002 – Google Shopping (“Froggle”) is Introduced

An early Google Ads evolution was the creation of Google Shopping – initially known as “Froggle” – which forever changed how people searched for and purchased products online. Users could now search for products directly and compare prices and availability across different online retailers. Businesses started showcasing their products to interested consumers more visually appealingly.

November 2005 – Conversion Tracking is Introduced Within Google Ads

This new process in Google Ads meant that advertisers could now track user actions once they clicked on their ads. This data-driven feature provided valuable insights into campaign performance and return on investment (ROI), which let advertisers optimize their strategies.

November 2005 – Google Analytics is Launched

The introduction of Google Analytics was a major milestone in the Google Ads timeline. The integration between Google Ads and Google Analytics gave advertisers a comprehensive understanding of their customers’ journeys from ad click to website interaction, further enhancing the effectiveness of Google Ads.

October 2008 – Display Ads Roll Out

Google expanded its advertising capabilities with visual ad formats, including image and video ads. These ads could be displayed on a wide range of websites across the Google Display Network, which encompasses some of the most popular websites, including and YouTube. This expansion offered advertisers new opportunities to engage with their target audiences through visually compelling advertisements, not just text-based ads.

May 2010 – Broad Match Modifier (BMM) Keywords is Introduced

With Broad Match Modifier (BMM) keywords, Google increased flexibility and control of keyword targeting in Google Ads. BMM allowed advertisers to specify essential terms within a keyword phrase using a “+” symbol, ensuring that ads would be triggered for searches containing those terms in any order. This opened up targeting for savvy digital marketers, allowing Google’s algorithm to find relevant search terms the marketer hasn’t thought to capitalize upon yet.

April 2012 – Google Analytics is Upgraded to Universal Analytics

This advertiser-side upgrade introduced cross-device and cross-platform tracking, which enabled a more comprehensive understanding of user behavior and engagement across different devices and touchpoints. Google Analytics now aligned more closely with the evolving digital landscape. Now you could target a consumer whether they were on their cell phone or desktop computer.

October 2012 – Google Rebranded “Froggle” to Google Shopping and Introduced a Pay-To-Play Model

Google Shopping transitioned from a free comparison service to a pay-to-play model requiring merchants to bid for visibility and placement within Google Shopping search results. Google Shopping now:

  • Aligned more closely with the current advertising ecosystem
  • Encouraged merchants to invest in Google Ads to promote their products
  • Further integrated advertising and e-commerce on the platform

February 2013 – Enhanced Campaigns Rolled Out, Making Cross-Device Targeting an Option

This small but important change recognized the increasing prevalence of multi-device usage and was a significant step towards continuing to enable Google to optimize ad targeting across different devices better. Now, advertisers could combine desktop and mobile targeting into a single campaign.

April 2013 – Universal Analytics Becomes Available for All Customers

With Universal Analytics, businesses of all sizes could gain better insights into their audiences’ behaviors and make data-driven decisions to optimize their Google Ads campaigns.

May 2013 – In-Market Audiences is Introduced (First Called “In-Market Buyers”)

Google Ads now had an even more powerful targeting tool for advertisers. In-market audiences enabled advertisers to reach users actively researching and showing purchase intent for specific products or services. Advertisers could focus their efforts on audiences more likely to convert, improving the efficiency and effectiveness of their campaigns. This success proved that Google’s automation tools can help advertisers find their ideal customers, assisting advertisers to take a small step towards intent targeting away from relying only on keywords.

August 2014 – Google Changes Match Type for Keywords, Applying Close Variants

A major push in the evolution of Google Ads, close variants broadened the scope of keyword matching, allowing ads to be shown for searches that included variations or misspellings of the targeted keywords. With this, ad visibility increased significantly. Advertisers could now capture relevant traffic – even with slight variations in search queries.

October 2014 – Custom Affinity Audiences is Introduced

Building on the success of in-market audiences, Google rolled out custom affinity audiences to help advertisers reach relevant customers. Now, thanks to these audiences, advertisers could define audience segments based on their specific interests, behaviors, or preferences. They could now tailor campaigns to reach highly relevant and engaged audiences for better results.

May 2016 – Google Introduced Smart Bidding

The introduction of smart bidding in 2016 marked a significant advancement in bid management within Google Ads. Smart bidding leveraged machine learning algorithms to automate the process, optimizing real-time bids based on various signals and conversion data. This automation allowed advertisers to maximize the value of their ad spend and improve campaign performance by automatically adjusting bids to achieve their desired goals.

March 2017 – Exact Match Includes Close Variants

This change in search keywords allowed ads to be triggered for searches with the same meaning as the exact match keyword – even with slight variations. Targeted ads began to capture even more relevant traffic.

October 2017 – Budgets Can Spend 2x Daily Instead of Just 1.2x

The increase in daily budget flexibility allowed advertisers to spend up to twice the daily Google Ads budget on certain days, beyond the previous limit of 1.2 times. This gave advertisers more control over their ad delivery, allowing for better use of advertising budgets. They could take advantage of spikes in demand or specific promotional periods without being constrained by daily budget limits.

November 2017 – Custom Intent Audiences is Introduced

Google continued to focus on the importance of audience targeting. Custom intent audiences enabled advertisers to reach users who had already demonstrated purchase intent based on recent search activities. This feature brought about new tailored audiences and ads that could increase the relevance of campaigns.

May 2018 – Responsive Display Ads Become the Default Display Ad Type

The now-default responsive display ads automatically adjust their size, format, and appearance to fit available ad spaces across different websites. This update ensured that advertisers’ display ads would be visually appealing and well-optimized, regardless of the placement or device used by the viewer. It also opened up more placements across the web, so you were no longer limited by the ad sizes you provided Google. Google could create new ads to fit within any ad placement, helping you reach your ideal audience no matter where they were on the web.

May 2018 – Smart Shopping Ads are Launched

Smart shopping ads utilized machine learning algorithms to optimize ad delivery and placement across various Google networks, such as Search and Gmail. This maximized the reach, conversion rates, and return on ad spend for advertisers because it leveraged Google’s advanced targeting and optimization capabilities.

July 2018 – Responsive Search Ads Introduced

Google Ads introduced increased flexibility and automation to streamline the ad creation process. Responsive search ads allowed advertisers to provide multiple headlines and descriptions, and Google’s machine learning algorithms would automatically test and optimize different combinations to find the most effective ad variations. 

February 2019 – Phrase Match and BMM Keywords Start Matching for Words They Consider to Have the Same Meaning

This common-sense change allowed advertisers to capture relevant traffic and reach their target audience even when the specific keyword variations were not explicitly included in their keyword list. 

October 2019 – Max Conversion Value Bid Strategy is Rolled Out

The new bidding option focused on maximizing the total conversion value generated from ad campaigns by leveraging historical data and machine learning algorithms to automatically set bids and allocate budget based on the potential value of each conversion. 

February 2021 – BMM Keywords is Deprecated, and Phrase Match Becomes What BMM Was

In 2021, Google deprecated BMM (Broad Match Modifier) keywords and transitioned their functionality to phrase match keywords. Doing so helped simplify the keyword matching options within Google Ads, aligning them with advertiser feedback and industry trends. Phrase match keywords became more flexible, matching searches with the same meaning as the keyword phrase while maintaining a higher degree of control compared to broad match keywords.

June 2021 – ETAs are Deprecated

Expanded Text Ads (ETAs) were the standard ad format that allowed advertisers to provide a few headlines and descriptions. Now, all advertisers were forced to create Responsive Search Ads, which leveraged automation and machine learning to optimize ad variations and improve performance. 

November 2021 – Performance Max is Rolled Out to All Advertisers

In keeping with the move toward automation and audience targeting, Performance Max ads leverage machine learning to optimize ad delivery across multiple Google placements, such as YouTube, Search, Display, Shopping, and Discover. By using Performance Max, advertisers would be able to reach a broader audience across the entire Google ecosystem.

July 2022 – tROAS And tCPA Targets Layered Onto Max Conversion and Max Conversion Value Strategies, Simplifying Bid Strategies, Removing the tROAS and tCPA Options as Standalone Strategies

A more simplified ad strategy consolidated bid management options and eliminated the standalone tROAS and tCPA strategies. It provided advertisers with streamlined bid capabilities and an easy way to change between maximize conversion value and target return on ad spend (tROAS) or between maximize conversions and target cost per conversion (tCPA). This easy change helped limit the dreaded “learning” phase, which can impact campaign efficiency.

September 2022 – Smart Shopping Ads Deprecated in Favor of Performance Max Ads

Further building on automation models, Google consolidated ad formats and strategies within Performance Max campaigns, offering advertisers a holistic, automated solution that optimized ad delivery. Google left standard shopping campaigns and Performance Max ads as the only two options for e-commerce advertisers looking to run ads with an automated shopping feed.

February 2023 – Google Introduces YouTube Shorts Advertising for Top Spending Clients (In Beta)

YouTube shorts are short-form vertical videos that capture users’ attention in a mobile-friendly format. By offering advertising options specifically for top spending clients, Google aims to attract high-value advertisers and capitalize on the popularity of short-form video content. 

March 2023 – Google Starts Rolling Out a New Ads Interface That Groups Audiences, Keywords, and Content Targeting All In One Tab

This change streamlines the user interface, making navigating and managing their targeting options easier for advertisers. By consolidating these features into a single tab, Google aims to improve the efficiency and effectiveness of campaign optimization.

May 2023 – Google Marketing Live

The introduction of GA4 (Google Analytics 4) in 2023 addresses privacy concerns and the evolving landscape of data tracking. GA4 replaces the previous version of Google Analytics and focuses on privacy-centric and consent-based tracking methods. It shifts away from relying solely on cookie-based tracking and incorporates event-based tracking and machine learning (ML) capabilities to provide advertisers with valuable insights while respecting user privacy preferences. Within Google Marketing Live, Google also introduced the Generative Search experience, new Demand Generation ad type (which appears to be similar to a Performance Max ad type without search placements), and new optimizations for Performance Max ads that provide advertisers with better insight into performance.

July 2023 – GA4 is Introduced to Eliminate Cookie-Based Tracking Because of Privacy Concerns

The introduction of GA4 (Google Analytics 4) in 2023 addresses privacy concerns and the evolving landscape of data tracking. GA4 replaces the previous version of Google Analytics and focuses on privacy-centric and consent-based tracking methods. It shifts away from relying solely on cookie-based tracking and incorporates event-based tracking and machine learning (ML) capabilities to provide advertisers with valuable insights while respecting user privacy preferences. 

August 2023 – Google Removes Similar Audiences 

In order to meet new privacy demands, Google deprecated similar audiences in favor of “Optimized Targeting” which acts akin to a similar audience, except it also includes first-party lists. The change to Optimized Targeting is a sign of the future of ads and marketing. As third-party cookies become less and less reliable, advertisers will need to rely on first-party data and other signals to reach their target audiences. This will require a more sophisticated approach to targeting, but it also presents an opportunity for advertisers to build stronger relationships with their customers.
