Google Ads for B2B SaaS

Google Ads is the most important paid acquisition channel for most B2B SaaS companies. It captures intent. People who type "alternative to Salesforce" or "best CRM for small business" are further down the funnel than someone who scrolls through LinkedIn or Twitter. That intent makes Google Ads efficient when you run it well, and expensive when you run it poorly.

This guide is for marketing teams at small B2B SaaS companies that want to build a Google Ads program from scratch, or fix one that is not working. It covers what is different about B2B SaaS, what to do in your first 90 days, and where Hero Marketer fits. It assumes that you know how the Google Ads auction works.

A short reminder: Ad Rank decides which ads show. Ad Rank uses your bid and the quality of your ad and landing page at auction time. It also uses the search context and the expected effect of your assets, such as sitelinks. Quality Score is a diagnostic. Google does not use Quality Score in the auction. For other terms, see the Glossary.

What is different about B2B SaaS​

A few characteristics that shape how Google Ads works specifically for B2B SaaS:

Higher CPCs​

B2B SaaS keywords are expensive. A click on "CRM software" might cost $20 or more. That is because:

  • The lifetime value per customer is high (often thousands of dollars each year), so advertisers can afford to pay more.
  • Competition is dense in most SaaS categories.
  • Buying intent is high. People who search do not browse for fun.

A $20 CPC sounds scary. But it is fine if your customer is worth $5,000 in lifetime value and converts at 2 percent.

Longer sales cycles​

A click rarely converts directly to revenue in B2B SaaS. A click might lead to a free trial, then a sales call weeks later, then a deal months after that.

This complicates measurement. Your Google Ads dashboard will show clicks and immediate conversions (sign ups, demo requests). The actual revenue impact is downstream and shows up in your CRM or revenue tools, not in Google Ads.

You have to bridge this gap. The honest way: track sign ups or demo requests in Google Ads, then connect downstream revenue to those leads in your own analytics or CRM. The lazy way: optimize on sign ups alone and hope they correlate with revenue. The lazy way works at first. Eventually you will need to bridge the gap.

Smaller markets​

A B2C product might address tens of millions of consumers. A B2B SaaS product might address a few thousand specific buyer roles at a few thousand specific companies.

Smaller markets mean:

  • Lower keyword volumes. "CRM" gets searched a lot. "CRM for sales engineering teams at Series B startups" does not get searched much.
  • Diminishing returns set in faster. Once you have captured the demand, more budget does not produce more conversions. It just bids prices up.
  • Targeting can be sharper with smaller markets. You can afford specific, intent rich keywords, not broad, untargeted ones.

Brand matters more​

In B2B SaaS, the buyer often researches several vendors before choosing. They will type your competitors' names into Google. You want to show up there.

This is the "alternative to X" pattern. It is one of the highest converting strategies in B2B SaaS. Google lets you use a competitor's name as a keyword. Keep the competitor's name out of your ad text, because Google can restrict it when the trademark owner complains.

Your first 90 days​

A reasonable plan if you start from zero.

Days 1 to 7: setup and first campaign​

  • Set up conversion tracking. At minimum, track sign ups or demo requests as conversions. Without conversion data, you cannot see what is working.
  • Build your first campaign. Start with one cluster, ideally a high intent one (for example, "alternative to [competitor]" or "[your category] for [your customer type]").
  • Set a daily budget that is large enough for about 50 clicks a week. The formula is your cluster's average CPC × 50 ÷ 7. At a $10 CPC, that is about $70 a day. If that is too much, pick a cheaper cluster.
  • Launch.

If you use Hero Marketer, the campaign wizard builds the first campaign: keywords, ad copy, and 4 sitelinks. The wizard recommends a monthly budget from the cluster. You can change it before you launch. For the 50 clicks a week amount above, type the daily amount times 30.4, for example about $2,128 a month for $70 a day. To change the budget after you publish, ask Hero AI. Set up conversion tracking in Google Ads yourself, because Hero Marketer does not set it up. See Create your first campaign.

Days 8 to 30: learn​

  • Do not change anything for the first 7 to 14 days. Let Google's algorithm learn.
  • Watch the search terms report. Look for queries that should not have triggered your ads. Add those as negative keywords. In Hero Marketer, each campaign page has a Search terms tab. You can also ask Hero AI which search terms waste spend.
  • Watch CTR and conversion rate. CTR below 1 percent suggests ad copy does not match queries. Conversion rate below 0.5 percent suggests the landing page does not match the ad promise.

Days 31 to 60: refine​

  • Add a second campaign for a different cluster. Now you have two keyword clusters to compare.
  • Iterate on ad copy. Replace the headlines that perform worst. Write new headlines from the ones that work.
  • Test sitelinks and callouts if you have not tested them yet. They cost nothing to add.
  • Look at conversion data. Do clicks convert? At what cost? Compare the cost to your target CPA.

Days 61 to 90: scale or kill​

By day 90 you should know:

  • Which cluster converts best at what cost.
  • What ad copy patterns work.
  • Whether your target CPA is achievable in this category.

Then either:

  • Scale. Increase budget on what works. Add more campaigns that target adjacent clusters.
  • Kill. If no campaign hit your target CPA after 90 days of iteration, Google Ads might not be the right channel for your product right now. That is a real outcome worth knowing.

Common traps​

A few mistakes lean SaaS teams make. This guide helps you avoid them.

"Set it and forget it"​

Google Ads is not a channel you set up once and leave alone. The algorithm learns, your competition changes, and search behavior shifts. A campaign that worked six months ago may not work now. Plan for ongoing maintenance, not one time setup.

The wrong optimization metric​

If you optimize for clicks, you will get clicks. They might not be the right clicks. Always judge results on conversions, or better, on revenue if you can connect the data. This is also true when a new campaign bids with Maximize Clicks.

Broad keywords without negatives​

Broad match keywords without negative keyword lists waste budget on irrelevant queries. Start new keywords as Exact match. Add Phrase match when you want more reach. Use Broad match only on a Smart Bidding campaign that has about 15 or more conversions in 30 days. Review the search terms every week, and add negative keywords as Phrase match.

Neglected landing pages​

Your landing page determines conversion rate. Even great ads with great targeting will not convert on a poor landing page. Spend at least as much time on landing pages as on ad copy.

Everything done by hand​

Some teams build and manage campaigns by hand for hours every week, for their own product or for several clients. This mechanical work takes time from decisions. Tools can do the mechanical parts. Hero Marketer's campaign wizard and Hero AI do the repetitive work, so you spend your time on review and decisions.

Where Hero Marketer fits​

Hero Marketer helps B2B SaaS teams run Google Ads. It has four parts:

  • Hero AI. Hero AI answers questions about your Google Ads account. It finds why a metric moved and recommends the next change. A change occurs only when you click Approve and apply on the card that shows the change.
  • Daily checks. Hero Marketer checks each connected account for 17 kinds of problems, such as broken conversion tracking and search terms that waste budget. Daily checks cost 0.25 credits a day for each connected account.
  • Automations. Automations are optional and off by default. An automation that you turn on acts without approval each time, within daily caps. You can revert each action with one click.
  • The campaign wizard. The wizard builds and publishes a Search campaign from one seed keyword: keyword clusters, ad copy from your product context, and 4 sitelinks.

Hero Marketer does not replace you. You still decide what to change and what to approve.
