Digital advertising for SaaS companies

Most first-time SaaS media buyers get the channel mix roughly right and the sequence badly wrong. They open LinkedIn Campaign Manager in month one because LinkedIn is where B2B buyers live, burn $12,000 across eight weeks, hand sales 40 leads that get marked unqualified, and conclude that paid does not work in their category. The demand was there the whole time. It was sitting in Google, in the shape of 300 people a month typing a competitor’s name with the word alternatives attached, and nobody had bid on it.

Channel choice is the smaller decision. What follows is what each of the nine buyable channels costs to test honestly, what it gives back, and where it belongs in the queue.

What has to be true before you buy any media

Three things, none optional: a conversion event that sales agrees is a real lead, a landing page that is not your homepage, and a written definition of a qualified lead that both teams have actually read.

Skip any of the three and the first quarter goes on arguing about whose numbers are right rather than which channel works. The standard version of this argument: marketing reports 180 conversions, sales says it spoke to 22 people worth speaking to, and both are correct because they are counting different objects.

The tracking decision matters more than the creative decision at this stage. If your conversion event is a form submission on a gated PDF, every bidding algorithm you touch will spend the rest of its life finding people who enjoy downloading PDFs. That single choice wastes more SaaS budget than weak targeting, weak copy and weak landing pages put together, which is why it opens the list of PPC mistakes that drain accounts.

The nine channels a SaaS company can actually buy

These are the channels with enough B2B software inventory to matter. Everything else, from billboards to conference app takeovers, is a brand expense dressed as performance.

Google Search

Buy this first and argue about it later. Search is the only channel where the buyer has already written down their problem, which is why brand terms convert at four to eight times the rate of anything else you will run. Non-brand splits into three tiers worth very different money: competitor comparison terms, category terms, and problem terms. Competitor terms convert hardest and cost least per acquisition in most SaaS categories. Category terms such as project management software carry $12 to $25 clicks and close in the low single digits. Problem terms rarely pay unless you have a self-serve product. First readable signal lands in two to three weeks at $5,000 a month.

Microsoft Ads

The efficiency play nobody runs early enough. Import your Google campaigns, cut bids 20 percent, and watch cost per click drop by a third or more on the same keyword set. Volume is roughly a tenth to a quarter of Google in most B2B software categories, so this does not replace anything, it just makes the blended number better. The audience skews older, more corporate and more likely to sit inside a Windows-managed environment, which flatters enterprise-facing products. Minimum viable test is $1,500 a month because the CPCs are lower and you still reach lead volume. Signal in three weeks.

YouTube and Demand Gen

Verdict: run it second or third, and only for retargeting and lookalike expansion until you have a video that holds attention past 15 seconds. Google folded the old Discovery format into Demand Gen, which now serves across YouTube, Discover and Gmail from one campaign. Cost per completed view sits in the cents. Cost per qualified lead looks fine and lies, because view-through conversions inflate it. Budget $6,000 a month for six weeks and judge it on incremental branded search volume, not on the platform’s conversion column. Demand Gen is the channel most likely to take credit for demand that Google Search already captured.

LinkedIn

The most oversold channel in B2B and still the right answer for enterprise ACVs. Targeting by job title, company size and named account list is genuinely better than anywhere else. Clicks cost $9 to $16, gated downloads land at $250 to $700, and demo requests routinely cost four figures. The economics only work above roughly $20,000 ACV, and they only work at all if you stop judging it on last-click cost per lead, since LinkedIn creates demand that converts later in Google. Budget $9,000 a month for a fair test and expect six weeks before creative learning settles. The detail lives in LinkedIn Ads for SaaS.

Meta

Undervalued for self-serve and PLG products, near useless for enterprise. CPMs are a fraction of LinkedIn’s and the targeting is worse, so the play is broad reach plus retargeting rather than precision. Products with a free tier, a consumer-adjacent use case or a prosumer buyer do fine here: think design tools, scheduling, form builders, anything Canva or Calendly shaped. Products selling to a security review committee do not. Test at $3,000 a month, keep the offer to a free trial rather than a demo, and expect four weeks before the algorithm settles.

Reddit

Cheap, hostile and excellent for developer tools. Subreddit targeting puts you in front of a genuinely self-selected audience for $0.80 to $3 a click, which is a tenth of LinkedIn. The catch is that Reddit punishes advertising that sounds like advertising, so the creative has to read like a person who uses the product. Conversation ads and promoted posts in narrow subreddits outperform interest targeting by a wide margin. Test at $2,000 a month. Watch the comments daily, because an unanswered critical comment under a promoted post does more brand damage than the campaign does good.

Review marketplaces

G2, Capterra, TrustRadius and Software Advice sell clicks from people who are already building a shortlist, which makes them behave like search rather than display. Cost per click runs $5 in quiet categories and $40 in crowded ones such as CRM or project management. The leads are real and they decay fast: a Capterra lead contacted in an hour converts several times better than one contacted the next day. Budget $2,500 a month minimum, and do not switch it on until you have the SLA in writing. Buying review-site traffic without a follow-up commitment is the most reliably wasted money in SaaS advertising.

Newsletter and podcast sponsorships

The channel that works best and measures worst. A well-chosen niche newsletter with 20,000 engaged subscribers costs $2,000 to $6,000 a placement and can outperform a quarter of LinkedIn spend, but the tracking is a vanity URL and a promo code, so attribution is partly faith. Buy three placements in the same publication before judging it, since one-off sponsorships almost always underperform. The tell that it worked: branded search volume and direct traffic rise in the 72 hours after the send. Best fit is a defined community around a job function, which is why Lenny’s Newsletter and similar operator publications command the rates they do.

Programmatic ABM platforms

6sense, Demandbase and Terminus sell intent data plus display inventory against a named account list. Platform contracts commonly start near $60,000 a year before media, which prices out anything below roughly $40,000 ACV and a defined target account list of a few hundred names. What you get is account-level intent scoring and air cover, which shortens cycles and improves meeting acceptance rates. What you do not get is a defensible cost per lead. Judge these on account engagement lift and pipeline velocity across a quarter, and be suspicious of any dashboard that claims display drove an enterprise deal.

Why Microsoft Ads is the most underbought channel in B2B software

Because it looks small and the reporting interface is unloved. Neither is a reason to skip 30 to 50 percent cheaper clicks against the same commercial intent.

The mechanics are unglamorous. Microsoft Advertising serves Bing, Yahoo, DuckDuckGo and, more usefully, the default search built into Windows and Edge across managed corporate devices. That distribution is the whole argument: the people using the browser their IT department configured are disproportionately the people who buy enterprise software. Microsoft’s own LinkedIn profile targeting layered on top of search campaigns is a genuine advantage you cannot buy in Google, letting you bid up company size or industry on a category keyword.

The honest limitation is volume. If Google Search delivers 400 clicks a month on your non-brand set, Microsoft will deliver 40 to 100. That will not change your growth curve. It will improve your blended CPL by five to fifteen percent for an afternoon’s work, which is a better return than most optimisation projects. Import, then prune: the imported campaigns bring negative keyword gaps with them, and Microsoft’s search partner network needs watching for junk placements.

The order to switch channels on

Start with the demand that already exists, prove the unit economics on it, then buy progressively colder audiences with money that channel generated. The sequence matters more than the mix because each step funds and informs the next one.

Two exceptions to this order are real. A category-creating product with no existing search demand should skip to LinkedIn and communities, because there is nothing to capture. A pure PLG product with a sub-$100 monthly price should weight Meta and Reddit far earlier, since the click economics of enterprise search never clear at that ACV. Everyone else follows the sequence, and the SaaS advertising strategy playbook covers how to adjust it for a hybrid motion.

What the sequence looks like at three budget levels

Budget determines how many channels you can honestly run, not how ambitious your plan is. Spreading $8,000 across five channels produces five underpowered tests and no conclusions.

The $30,000 tier is where most SaaS paid programs break, because it is the first point at which the account is too complex for a part-time owner and too small for a specialist agency retainer to look cheap. That is the decision point covered in choosing a SaaS PPC agency, and the honest answer is often a contractor rather than either extreme.

Three signs a channel should be switched off

Kill a channel when cost per qualified lead doubles from its stable baseline for two consecutive months, when sales rejects more than 70 percent of what it sends, or when you cannot add 30 percent more budget without CPL breaking.

That third one catches people out. A channel producing 25 great leads a month at $200 each looks healthy right up until you double the budget and discover it produces 31 leads at $320. Some channels have a hard ceiling set by available inventory, and Reddit, niche newsletters and small review categories all hit theirs early. Test the ceiling deliberately with a 30 percent budget increase for three weeks before you build a plan around scaling it.

There is a fourth reason that is not about performance at all: you cannot staff it. A channel nobody owns drifts. If a media buyer is already running four channels properly, the fifth will be run badly, and badly run channels do not produce neutral results, they produce expensive negative ones.

What to do in the next two weeks

Pull the last 90 days of spend by channel, and next to each line write the number of leads sales actually accepted. Not conversions. Accepted. Most teams discover that two channels produced 80 percent of the accepted volume and the rest existed because somebody switched them on once and nobody switched them off.

Then do three things: fix the conversion event so it fires on the qualified action, add brand search if you are somehow not running it, and set a 30-day review date on every channel that failed the accepted-lead test. Compare your numbers against the SaaS PPC benchmarks before you decide anything is broken, because a $420 cost per lead is excellent at $60,000 ACV and catastrophic at $4,000. The wider operating model, including how paid fits alongside lifecycle and organic, sits in SaaS performance marketing, and platform-level feature differences are broken down in SaaS advertising platforms compared.

One more thing worth saying plainly. Paid media does not create a market. It finds people already moving and gets to them first, and for the handful of SaaS companies genuinely inventing a category, the honest recommendation is to spend the first year on content, community and founder-led sales, then come back to this page. The rest of the operating detail sits in the SaaS PPC and paid ads hub.
