Smart Bidding harnesses machine learning algorithms to maximize conversions and revenue for Google Ads campaigns. Learn how and when to use Smart Bidding (with exact-match keywords, ample budget, A/B testing data, and conversion history) in this expert guide.
Do bid adjustments and conversion tracking eat up too much time in your marketing strategy? It might be time to let Google’s advanced machine algorithms take the wheel. Enter the world of Smart Bidding.
But what exactly is Smart Bidding and how do you know when to use it? We asked Dorsa Aerabi, a paid media expert and marketing manager here at HawkSEM. She shares her expert advice on the Smart Bidding process and when they offer the most return on investment (ROI) for your Google Ads campaigns.
Let’s jump straight in.
What is Smart Bidding?
Smart Bidding is a collection of bidding strategies on Google Ads that use artificial intelligence (AI), specifically machine learning algorithms, to inform your bid adjustments in real-time.
Sometimes referred to as “auction-time bidding,” Smart Bidding aims to achieve one of two broad business goals:
- Improve the quantity of conversions
- Improve the quality of conversions
Google’s algorithms assess historical data from your previous campaigns as well as audience data subsets to deliver the best possible bid value for your campaigns.
The best part? Smart Bidding is automated, meaning all this work happens behind the scenes without you having to adjust the bids yourself. Google has its own library of signals that power its algorithms.
Contextual signals that inform Smart Bidding
Your audience might browse the web at certain times of the day. Or, you might notice more conversions from people who use Chrome versus Microsoft Edge. These are just a few examples of contextual signals you can toggle on Google Ads to inform its bid adjustments.
But they don’t just refer to your audience’s attributes. Other examples of contextual signals include:
- Seasonality: Specific times of the year, like the holidays
- Price competitiveness: Adjustments based on how your price stacks up against competitors
- Website behavior: A potential customer’s browsing history, including previous visits to specific web pages
- Ad placement: Higher bids for audiences that see search ads on specific, higher-traffic, or conversion-heavy websites
- Location: Covers audiences’ physical locations as well as location intent within a search query
Long story short: thanks to these insights, you can maximize performance without having to spend hours collecting or analyzing it. Count us in!
Just make sure you give your campaigns the best possible chance for ROI by checking these boxes before you start your smart bidding journey.
When to use Smart Bidding search campaigns
We’ve seen the benefits of Smart Bidding, but is it always the right solution? Aerabi shares her ideal qualifiers for brands to use Smart Bidding to their highest advantage:
- When you have enough conversion history
- When you have a generous daily budget
- With exact-match keywords
- With A/B testing insights on your audience
Let’s break each of these down.
1. When you have enough conversion history
Google has a ton of back-end data at its disposal for its advanced machine-learning algorithms to make the best possible bids.
But what if your campaigns are brand-spankin’ new to the digital marketing scene? Aerabi says those algorithms may not have enough data to work with:
“For newer businesses or those new to Google Ads, it’s best to start with manual bidding to gather sufficient conversion data,” says Aerabi. “As your campaign gains more conversions and learnings, this is where we consider transitioning to Smart Bidding for better-automated optimization.”
Google recommends Smart Bidding for campaigns with a history of at least 30 conversions within the past month, ideally 50 for the target ROAS strategy. But if you work with a skilled, seasoned Google Ads agency like HawkSEM? Aerabi can work with much less:
“Generally speaking, if I see five to ten conversions within one month, I think that is a good time to opt into Smart Bidding,” says Aerabi.
2. When you have a generous daily budget
We love the Maximize Conversion Value strategy for its ROI potential. But Google’s algorithms have a tendency to be too aggressive too soon. How? They automate bid adjustments, meaning they might bid high for ostensibly high-value conversions that don’t stack up to your ROI goals. Talk about an influx of ad spend.
That’s why we’d recommend a budget of $10,000-15,000 per month before starting a Smart Bidding strategy. Still, you want to trade as much ROI as possible for those marketing dollars.
Aerabi says a close eye on bidding performance, historical data, and competition can help mitigate wasted ad spend:
“We recommend starting off with a more manual bidding strategy for businesses on a budget and based on the clients goals, performance, data, and competition,” says Aerabi. “We make an informed decision on whether or not it makes sense to test Smart Bidding.”
3. With exact-match keywords
If you’ve kept up with Google’s instructional content and tips articles, you might remember a recent article that favored broad-match keywords for Smart Bidding over exact-match. In Google’s words:
“Broad match gives you the most reach and conversions within your goals.”
Aerabi elaborates:
“Broad match with Smart Bidding [can] leverage the algorithm’s flexibility in identifying relevant searches and adjusting bids accordingly,” says Aerabi.
Eager to take Google’s advice, 62% of brands now use broad match for Smart Bidding campaigns.
But Aerabi has another ace up her sleeve:
“Introducing exact match keywords with Smart Bidding is one of the best strategies I have seen work, especially when you want to drive relevant traffic and have more control of keyword targeting and what search terms will look like,” says Aerabi.
In other words, if you want precise control and stronger ad quality, exact match with Smart Bidding is a match made in heaven.
4. With A/B testing insights on your audience
Every marketing strategy comes back to your audience, and Smart Bidding is no exception. If you’re new to ad campaigns, you might not have as much data on your audience as you’d like. But doesn’t Google Ads collect all that data for you already?
Maybe you can use Smart Bidding to collect intel on your audience before tweaking your strategy.
Aerabi says you can gather audience data from Smart Bidding by looking at conversion rates and details. However, it’s not an ideal approach:
“I don’t believe it’s designed to give data in this way since it optimizes bids based on historical data and not so much on demographic information.”
Plus, you’ll find yourself spending serious coin. The solution? Aerabi prefers A/B testing and leveraging Google Ads’ observation mode:
“A/B test different messaging to see what resonates best with your audience, or even implement tailored messaging for specific ad groups,” says Aerabi. “Additionally, using observation mode for in-market or affinity audiences in your campaigns can help provide insightful data on how these groups engage with your ads, without narrowing your reach.”
But here’s the kicker: your audience doesn’t exhibit the same behavior across every marketing platform. So, how do you cohere a marketing strategy that accounts for optimized tactics across every platform?
On top of extensive audience research, HawkSEM strategists turn to our proprietary tech, ConversionIQ. Its AI-generated insights and comprehensive analysis help us gather data for way more than a single group of Google Ads campaigns. It also feeds us data across customizable historical periods from multiple campaigns and marketing channels.
Ultimately, you’ll want to tailor your Smart Bidding efforts with the marketing objectives that mean the most to your brand. This is where Google’s Smart Bidding strategies play a crucial role.
Different types of Google Ads Smart Bidding strategies
As mentioned earlier, Smart Bidding can increase the number and quality of your conversions. But these results hinge on the type of strategy you select when you set up your Google Ads campaigns.
These five Smart Bidding strategies focus on different objectives, honing in on the goals you want to prioritize. We’ll also briefly cover two more automated bidding strategies that Aerabi uses in her paid search strategies. They’re similar to Smart Bidding strategies but technically don’t use auction-time bidding.
- Maximize conversions
- Target CPA
- Target Return on Ad Spend (ROAS)
- Maximize conversion value
- Automated bidding strategies
Let’s take a closer look.
1. Maximize conversions
Looking to pump up your leads and sales? Aerabi says this bidding method is your go-to:
“If there is budget flexibility and a goal to drive as many conversions as possible, we like to recommend starting with this bidding strategy.”
The Maximize Conversions strategy leverages historical campaign performance and audience signals to adjust bid amounts for the highest number of conversions possible with your given budget. You can also tweak this strategy to optimize for as many conversions as possible with a target cost per action (CPA).
Otherwise, the Smart Bidding algorithm will work with your ad budget.
2. Target CPA
Maybe you have conversions coming in, but they take a serious toll on your marketing budget. If your CPA is too high, you’ll spend a disproportionate amount of your budget on leads and conversions. With the Target CPA strategy, Google Ads works its magic to deliver customer actions (web visits, completed lead forms, purchases) within your target CPA.
Let’s say you currently pay an average of $25 per conversion, but you want to bring it down to $15. You’d set your target CPA to $15, and Google’s algorithms would work to get you conversions with that CPA as often as possible. Some criteria the algorithms assess include time of day, location, browser, device, and remarketing lists.
Another bonus? You can implement this strategy for one specific campaign, multiple, or a portfolio of campaign groups, depending on your budget and marketing needs.
3. Target Return on Ad Spend (ROAS)
Who loves ROI? You know we do—and so does Google when you select the Target ROAS bidding strategy.
Imagine you spend an average of about $100 for five conversions, which garner a total of $500 in revenue. In that case, your ROAS is 500%. Pretty sweet, right?
If you want to maintain those numbers, opt for the Target ROAS strategy. This way, Google will prioritize targets and set bids that generate a similar return.
But Google can’t make these predictions without enough data to work with. Meaning?
You need a history of 10-30 conversions with accompanying values within the last 7-30 days for Google’s algorithms to investigate. If you’re brand new to Google Ads, this strategy might not deliver the ROAS target you’re after because of insufficient data to inform bid choices.
4. Maximize Conversion Value
Consider two potential customers who see your ad: One might have certain signals similar to higher-value customers that make higher purchase orders or return purchases.
The other could be a serial browser. Similarly, you might place more value on a customer with a mobile device than a desktop, if the former is more consistent with your audience.
In the Maximize Conversion Value strategy, Google will assess audience signals like device, location, and shopping behavior.
Moreover, it’ll account for your brand’s input and conversion values, to bid higher on predicted higher-value conversions, and lower on lower-value conversions. You can also place set values on different types of conversions and have Google target them.
5. Automated bidding strategies
It’s easy to hone in on conversions and value in your paid search strategy. After all, who doesn’t want increased revenue and ROI? But a huge part of getting that revenue lies in brand awareness and niche authority.
This explains why our clients invest in SEO services to create informational, accurate, and authoritative content. The idea? To position themselves as reliable industry leaders to their audiences.
If you want to build brand awareness, you need to attract more people to your website. And that doesn’t always lead to a purchase. But it does set the stage for more conversions in the funnel down the line.
Here are Google’s two automated bidding strategies focused on brand awareness:
Target Impression Share
The Target Impression Share strategy adjusts bids to prioritize top SERP ad placement for specific keywords. If you struggle in a competitive niche and lose traffic to big competitors, Aerabi says this could be a useful strategy:
“In scenarios where a branded keyword faces significant competition, exploring Target Impression Share can be beneficial,” explains Aerabi. “This strategy aims to maximize ad impressions for the brand keyword, enhancing brand visibility and securing top ad placements.”
Then comes the power of clicks.
Maximize Clicks
Wondering how to supercharge clicks from your Google Ads account? The Maximize Clicks strategy lives up to its name. It focuses on maximal clicks for old and new campaigns within your given budget.
If you struggle with high cost-per-click (CPC) in your industry, this strategy is a sigh of relief. Google sets maximum CPCs on your behalf so you can reap the clicks without blowing through ad spend.
Just remember: if your audience is more active at certain times of day or year, you can’t target them with that criteria through the Maximize Clicks strategy.

Smart Bidding works best for ads backed with ample conversion attribution data, A/B testing insights, flexible budgets, and exact-match keywords.
