Google Ads
The world's dominant paid-search platform and the anchor of most US B2B and B2C paid-media stacks.
What Google Ads is
Google Ads (formerly Google AdWords, rebranded in 2018) is Google's paid advertising platform, spanning Search Ads (the sponsored results at the top of Google Search), Display Ads (image and video ads across the Google Display Network of 2M+ sites), YouTube Ads, Shopping Ads (Google Shopping), and Performance Max (automated cross-channel campaigns).
By revenue, Google Ads is the largest advertising business in history — roughly $250B/year in Google's advertising revenue. For most US businesses, some portion of Google Ads is table stakes: even brand-defensive campaigns bidding on the company's own name typically return positive ROAS.
Who uses Google Ads
Google Ads is used by essentially every US business that markets online, from local plumbers running $500/month Local Service Ads campaigns to Fortune 500 companies running eight-figure monthly programs. Its accessibility is the point: the platform is free to use; you only pay for the media placement, priced by auction.
What Google Ads costs
Free to use. Media costs are auction-priced and vary dramatically by category: from $0.50/click for low-competition keywords to $50+/click for high-value legal, insurance, and financial-services keywords. Typical US SMB campaigns run $1,000–$10,000/month in media spend; enterprise campaigns scale to seven figures monthly. Agency management fees typically add 10–20% of media spend, often with a floor.
Where Google Ads sits in the growth-vendor context
Google Ads shows up on shortlists in The Wall's Demand Gen pillar. Buyers who consider Google Ads typically also evaluate Meta Ads Manager, LinkedIn Campaign Manager, The Trade Desk — the shortlist question is usually not whether Google Ads is a good product (it generally is, or it wouldn't be on the list), but whether its center of gravity fits the company's shape.
Frequently asked
What is Google Ads used for?
Google Ads is used for paid search advertising (sponsored results on Google Search), display advertising (banner ads across websites), YouTube advertising, and shopping ads (product-listing ads on Google Shopping). Almost every business that markets online uses some portion of it.
How much does Google Ads cost?
The platform is free to use. Media costs are auction-priced: from ~$0.50/click for low-competition terms to $50+/click for high-value legal or financial-services terms. Typical US SMBs run $1,000–$10,000/month in media spend; enterprise budgets reach seven figures monthly.
Should I hire a Google Ads agency?
For accounts under ~$5,000/month in media spend running simple campaigns, DIY is often the right call — the account setup takes a day and ongoing management is a few hours a week. Above $5,000/month, or when campaigns involve complex negative keyword lists, product feeds, or attribution across long sales cycles, a specialist agency usually pays for itself.
What is Performance Max?
Performance Max is Google's AI-driven campaign type that runs a single unified campaign across Search, Display, YouTube, Shopping, Gmail, and Maps. Google's algorithms decide the mix. Powerful for straightforward direct-response goals; a black box for advertisers who need channel-level visibility.
What is the difference between Google Ads and Google Local Service Ads?
Google Ads is pay-per-click across the web. Google Local Service Ads (LSAs) is a separate product limited to specific service categories, priced per qualified lead instead of per click, requiring background/license verification, running above traditional Search Ads.
