Google is still one of the best places to start advertising online. It remains the world’s most popular search engine, and its ad platform now reaches people across Search, YouTube, Gmail, Discover, Maps, millions of partner websites and apps, and, increasingly, Google’s AI-powered search experiences.
In this guide, we cover what Google Ads is, how it has changed, and the best practices and tips that make campaigns succeed in 2026.
What is Google Ads?
Google Ads is Google’s own advertising platform. Its biggest advantage is intent: you can reach people at the moment they are already looking for the kind of product or service you sell, so your ads are relevant to them rather than an interruption.
Despite constant change in the ad tech landscape, Google Ads remains a core part of almost every online advertising strategy.
How Does Google Ads Work?
Businesses can market themselves on Google in two ways: SEO, which is free but slow to build, and paid advertising.
Google Ads is the paid advertising service. Advertisers bid in an auction for placements, and Google decides which ads to show based on the bid, ad type, ad quality, relevance, and expected impact. Depending on the campaign type, ads can appear on the search results page (including within AI Overviews and AI Mode), on YouTube, Gmail and Discover, in Google Maps, in Shopping results, or on websites and apps across the Google Display Network.
Results depend on strategy. Budget affects how far and how often your ads reach people, but ad quality, targeting signals and conversion data are what win customers—especially now that most bidding and targeting is driven by Google’s AI.
How Effective Are Google Ads?
Google is by far the most-used search engine. Google says it now handles more than 5 trillion searches a year—roughly 14 billion searches a day. According to StatCounter, Google held 89.94% of the global search engine market across all platforms in September 2026, and 78.12% on desktop, where Bing is its strongest competitor.
Because Google Ads is built on what people search for, it doesn’t just drive traffic—it also shows you what customers want, in their own words.
Performance benchmarks remain strong. WordStream’s 2026 Google Ads benchmarks (based on more than 13,000 search campaigns between April 2025 and March 2026) found these averages across industries:
- Click-through rate: 6.64%
- Average cost per click: $5.42
- Conversion rate: 8.18%
- Average cost per lead: $66.69—down year over year for the first time in five years
These numbers vary widely by industry, so treat them as a reference point rather than a target. And because every click costs money, reaching the right audience with the right message matters more than ever.
How Google Ads Evolved in 2026
The core principles haven’t changed: relevance, strong creative and good data still win. What has changed is how much of the work Google’s AI now does, where ads can appear, and how much control advertisers get over that automation. Here are the biggest developments since our last update.
Paid Search and AI Max for Search
Search ads still appear as sponsored results above and below the organic results, and advertisers still win placements through a keyword auction. The big shift is AI Max for Search, which Google introduced in beta in 2025. AI Max uses broad match and “keywordless” technology to find relevant queries beyond your keyword list, can customize ad text based on your landing pages and assets, and can send users to the most relevant page on your site.
In September 2026, Google began automatically upgrading eligible Search campaigns to AI Max. Dynamic Search Ads (DSA) are being phased out: new DSA campaigns can no longer be created, and remaining DSA campaigns are scheduled to migrate in February 2027 (Google Ads & Commerce Blog). New AI Max reports show which search terms, headlines and landing pages served together, so you can see what the automation is doing.
Ads in AI Overviews and AI Mode
Google’s AI-powered search experiences are now ad inventory. Ads in AI Overviews expanded in 2025, and Google has been rolling out ads in AI Mode, including new formats announced at Google Marketing Live 2026 such as Conversational Discovery ads and Highlighted Answers. As of September 2026, campaigns using exact and phrase match keywords are also eligible to serve in AI Mode. For advertisers, this means clear, benefit-led landing pages and assets matter even more—Google’s AI uses them to decide when and how your ad appears.
Performance Max (P-Max)
Performance Max is a fully automated campaign type that runs across all of Google’s inventory: Search, Shopping, YouTube, Display, Gmail, Discover and Maps. You provide headlines, descriptions, images, videos and audience signals, and Google builds and serves the best combinations.
The main complaint about P-Max used to be the “black box.” That has improved a lot. Since our last update, Google has added channel performance reporting, a full search terms report, campaign-level negative keywords (up to 10,000 per campaign), brand exclusions, and asset-level reporting and testing. P-Max is still best for advertisers who want to scale quickly with less manual management—but you can now see and steer far more of it.
Demand Gen
Demand Gen, the successor to Discovery campaigns, is Google’s campaign type for visually engaging ads that create and capture demand. It runs across YouTube (including Shorts and in-stream), Discover, Gmail, Google Maps and—since 2026—the Google Display Network.
Demand Gen offers a social-media-style experience with image, carousel and video-first creatives, lookalike and custom audiences, channel-level reporting and controls, and conversion-focused bidding. It is a strong fit for ecommerce, apps and lead generation.
Display Campaigns Are Moving into Demand Gen
In May 2026, Google announced it is retiring standalone Display campaigns in favor of Demand Gen. A migration tool began rolling out in June 2026, new standalone Display campaigns are being phased out, and remaining campaigns will be migrated automatically through 2027. The Display inventory itself isn’t going away—it now lives inside Demand Gen, and you can still run Display-only campaigns there using channel controls.
Smart Bidding Exploration
Smart Bidding Exploration lets Target ROAS (and increasingly Target CPA) campaigns use more flexible targets to find new, converting searches they would otherwise miss. Google has steadily expanded it in 2026, including to Shopping and Performance Max.
Gemini-Powered Tools
Gemini is now built into Google Ads. Highlights include Ask Advisor, an AI assistant that can analyze performance and help build and optimize campaigns; Asset Studio, for generating and editing images and videos; AI Brief, where you describe your brand voice and guardrails so Google’s AI follows them; and AI-powered insights and dashboards created from plain-language prompts.
NEW: Channel Prioritization and Budget Allocation
On October 14, 2026, Google introduced two optional controls that give advertisers more say over where their budget goes across Google’s channels. They are rolling out gradually to Search, Shopping, Performance Max and Demand Gen campaigns over the coming months, so availability may vary by account.
- Channel Prioritization: You set each channel to “High priority” or “Low priority.” Google funds high-priority channels first and sends the remaining budget to low-priority channels, while staying within your Target CPA or Target ROAS. In Search campaigns, Google Search, Search Partners and the Google Display Network can be placed in different tiers. In Performance Max and Demand Gen, Google-owned channels (such as Search, YouTube, Discover, Gmail and Maps) are grouped together. All channels default to High priority.
- Budget Allocation: For Low-priority channels, you can set an optional cap as a percentage of the campaign’s average daily budget. For example, a 5% allocation on a $1,000 daily budget means Google will aim to keep spend on that channel at or below $50 per day. Setting 0% stops spend on that channel. Google is clear that this is “best effort,” not a hard cap, and the limit resets daily.
- Where to find it: Account settings > Channel Prioritization. You can set an account-level default for each campaign type and override it at campaign level. Shared budgets and the Google Ads API are supported.
- What changes in February 2027: Search campaigns with Display Expansion will move to channel prioritization automatically, replacing the old setup in which up to 50% of budget could go to Display. To keep your current configuration, Google recommends setting the Display Network to Low priority with a 50% budget allocation.
Our take: This is one of the most meaningful control updates Google has shipped in years—especially for advertisers who want P-Max or Demand Gen reach without letting lower-intent placements take over the budget. Use it carefully, though. For campaigns that are already hitting their CPA or ROAS targets, restricting channels can limit the options Smart Bidding has to work with. Start with Low priority on channels you’re unsure about, apply modest caps, and measure the impact before going further. Google also says channel prioritization on its own will generally have little effect on Target CPA or ROAS campaigns that aren’t limited by budget—budget allocation caps are the lever there.

Google Search Ads Best Practices
Search ads appear at the top and bottom of the search results page, labeled “Sponsored.” They remain one of the most effective ad formats because:
- They can appear as soon as you win the auction—SEO can take months or years to deliver the same visibility.
- They appear above and below organic results, and can now also show in AI Overviews and AI Mode.
- They match what people are actively searching for.
- They are often the first thing users see.
Responsive search ads let you add up to 15 headlines (30 characters each) and 4 descriptions (90 characters each), and Google tests the combinations for you. To make the most of them:
- Speak your audience’s language. Use the terms your customers actually use, including industry terms they know.
- Include a call to action (CTA). Tell people exactly what to do next.
- Solve a problem or answer a question. Show how you meet the need behind the search.
- Leverage user intent. For example, a real estate ad might ask, “Looking to Buy a House?”
- Keep it simple and positive. Avoid jargon, negativity and anything that could feel insulting.
- Be genuine and make realistic promises. Overpromising hurts conversion rates and trust.
- Give Google enough variety. Write distinct headlines—benefits, features, offers, proof—so AI-generated combinations stay strong. Pin only where you must.
Your description should follow the headline with specific product information and the main benefits to the customer.
Display Inventory Now Lives in Demand Gen
Display ads appear across websites, apps and videos that users browse—Google says its Display ads reach over 3 million websites and over 650,000 apps, plus Google properties such as Gmail and YouTube. Because display ads reach people who aren’t necessarily searching for you, success depends on audience selection and creative. With Display moving into Demand Gen, keep these essentials in mind:
- Target the right audiences. Use customer lists, your website and app visitors, custom segments and lookalikes rather than broad demographic targeting alone.
- Make creative that works everywhere. Put your main message up front, design for mobile first, and create visually appealing ads in multiple formats. For responsive image assets, Google recommends 1200 × 628 px (1.91:1, minimum 600 × 314), 1200 × 1200 px (1:1, minimum 300 × 300) and 900 × 1600 px (9:16, minimum 600 × 1067), up to 5,120 KB each. Add video wherever you can.
- Use channel controls. In Demand Gen—and with the new Channel Prioritization controls—you decide how much of your budget goes to the Display Network versus YouTube, Discover and Gmail.
- Keep the message consistent. The ad and the landing page should tell the same story.
Google Ads Best Practices for Copy
Ad copy includes all the text in your paid ad: headlines, descriptions and the copy on the page the ad leads to. Some rules to follow:
- Make it easy to understand.
- Focus on the customer, not your business.
- Write about benefits, not just features.
- Avoid negative or overly technical language.
Keep landing page copy short and clear, too. Remember that ad copy is sales writing, not blog writing—it should sell outcomes. And with AI Max and Performance Max generating text from your assets and website, the quality and clarity of everything you write now shapes the ads Google creates on your behalf. Use brand guidelines (or AI Brief) to keep generated copy on message.
Google Ads Best Practices for Keywords
Keywords are still essential, even as Google expands beyond them. Knowing which searches lead to customers is the key to profitable campaigns.
- Think like your customers. Build lists around the problems and phrases real buyers use.
- Use the right match types. Broad match paired with Smart Bidding is now Google’s default recommendation for reach; phrase and exact match give you tighter control over high-value terms.
- Manage negative keywords. Review search terms reports regularly and exclude irrelevant queries—now possible in Performance Max too.
- Use professional research tools. Keyword Planner and third-party tools reveal volume, competition and new opportunities.
- Test continuously. Use experiments to compare match types, AI Max settings and keyword groupings over time.
Google Ads Best Practices for Landing Pages
A landing page is the page your ad sends users to, and it works like a sales letter. Your homepage can work for brand campaigns, but users searching for something specific should land on a page built for that need.
A good landing page has one purpose and one desired action—making a purchase, signing up for an email list, creating an account or another business goal. To make it effective:
- Make the offer and its value clear immediately.
- Make every piece of text matter to the reader and cut the fluff.
- Keep the CTA simple and visible.
- Show proof: reviews, results, guarantees.
- Make sure it loads fast and works well on mobile.
- Keep the offer consistent with the ad.
Landing pages also matter more for automation now. AI Max and Performance Max read your site to write ad text and choose final URLs, so clear, well-structured pages help Google show the right message to the right person.
Using Google Ads Assets (Formerly Extensions)
Assets—called “ad extensions” until Google renamed them in 2022—add extra information to your ads, increasing visibility and trust. The most common types are:
- Sitelinks
- Callouts
- Structured snippets
- Images
- Calls
- Prices
- Promotions
- Locations
- Lead forms
Many assets can now be generated automatically, and Google increasingly pulls promotions, images and videos from your website. Adding your own assets still gives you more control—and usually a competitive edge.
Google Ads Best Practices for Sitelinks
Sitelinks take users deeper into your site and appear below your ad text. Point them to high-value pages, such as specific products, offers or pricing—not generic pages like “About Us.” Test different sitelink text and URLs, and compare their performance in the Assets report in Google Ads.
Google Ads Tips
- Testing is everything. Small changes to targeting, keywords, headlines and copy can make a big difference. Use Google Ads Experiments—and now P-Max asset experiments—to test with statistical confidence.
- Feed the algorithm good data. Set up accurate conversion tracking with enhanced conversions, consent mode and first-party data. Better data means better automated bidding.
- Measure incrementality. Use conversion lift studies and channel-level reporting to understand what your campaigns actually add.
- Maintain relevance everywhere. Keep the message consistent from headline to landing page.
- Fill out all ad options. Use all available headlines, descriptions, images, videos and assets.
- Control the automation. Use brand guidelines, negative keywords, brand exclusions and the new Channel Prioritization controls to guide Google’s AI instead of switching it off.
Final Thoughts on Google Ads in 2026
Google Ads remains a dynamic and highly effective platform, but it is changing faster than ever. AI now handles much of the targeting, bidding and creative work, which makes your strategy, data and creative inputs more important, not less. Keep testing, stay relevant, use the new controls to steer automation, and consistently deliver value to your audience.
