SaaS marketing channels, ranked

Channel advice in SaaS is mostly opinion with no arithmetic attached. Here’s the version with numbers: fourteen channels, what each costs, how long before you know if it’s working, and the ACV band where it stops being viable.

The single most useful filter is cost per opportunity as a share of first year contract value. Under about 10 percent, keep going. Over 15 percent, you’re subsidising the channel from somewhere else.

1. Review marketplaces

The most underrated paid channel below $25K ACV, and I’d argue it’s not close. G2, Capterra and TrustRadius put you in front of buyers who have already decided to buy something in your category and are now picking.

Entry cost is genuinely low. Capterra runs pay per click from about $2 with a $500 monthly minimum, so a seed stage company can test it for less than one week of an SDR’s salary. G2 clicks run $2 to $15, above $20 in crowded categories like CRM or project management. G2 Marketing Solutions contracts typically start near $25,000 a year, which is the point where the channel needs a real budget conversation.

The catch nobody mentions: your profile does the converting, not your ads. A category page with nine reviews against a competitor’s four hundred will burn budget regardless of bid. Fix the review count first, then buy clicks.

2. Bottom of funnel SEO

Slowest to start, cheapest to sustain. Pages targeting “alternatives to X”, “X vs Y”, “best software for Z” convert at multiples of general blog content because the reader is comparing, not learning.

First ranking signal takes six to twelve months, which is the reason most teams give up. The compounding is real though: a page that ranks produces leads for years at zero marginal cost. Organic marketing for SaaS covers building this properly.

What’s changed in 2026: AI Overviews depress click through on informational queries substantially, so the informational half of your SEO now earns citation more than traffic. Bottom of funnel pages, where the buyer wants to see a product, hold up much better.

3. Paid search on high intent terms

Competitor names, “best [category] software”, and “[category] pricing”. Signal within a fortnight, which makes it the fastest channel to validate a message.

Costs escalate fast. Competitor terms in mature categories commonly run $30 to $60 a click, and the volume ceiling arrives quickly. Most SaaS companies exhaust genuinely high intent search volume within a $15K to $40K monthly budget, after which additional spend buys progressively worse intent.

Run it. Cap it. Don’t let an agency talk you into broad match expansion to spend the budget.

4. Integration and partner listings

Underused and structurally excellent. If you integrate with Salesforce, HubSpot, Slack or Zapier, their directories are search-visible surfaces with buying intent attached, and you pay in engineering time rather than media spend.

Zapier’s directory in particular sends meaningful traffic to small apps, and the pages rank for “[your tool] [their tool] integration” queries you’d struggle to win otherwise. Two to six months to signal, then it compounds with every partner you add.

5. Founder-led outbound

For companies under $3M ARR this is often the highest return activity available, and the arithmetic is brutal in its favour: a founder emailing two hundred named accounts costs tools money and time, nothing else.

Reply rates for genuinely personalised founder outreach run several times what an SDR sequence gets. Tools like Clay and Apollo make the list building fast. The limitation is the founder’s calendar, which caps this at roughly twenty meaningful conversations a week before something else breaks.

6. SDR outbound

The scaled version, and considerably worse per dollar. A fully loaded SDR runs $90,000 to $140,000 including tooling and management. At typical B2B meeting rates, cost per meeting lands between $400 and $900, and cost per opportunity between $1,500 and $4,000.

That only works above roughly $25K ACV, and only if you’ve already proven the message works with founder outbound. Hiring SDRs to discover your message is an expensive way to run research.

7. LinkedIn paid

Excellent targeting, punishing costs. CPLs commonly land between $150 and $400 for B2B SaaS, with demo requests at the top of that band and higher.

Lead gen forms produce the cheapest fills and the worst downstream conversion, because prefilled forms strip out the small intent signal that friction provided. If you use them, expect heavy MQL attrition and budget for it.

Viable above $40K ACV. Below that, the cost per opportunity rarely stays under 10 percent of contract value.

8. Comparison and alternatives pages

Technically SEO, but they deserve separate treatment because they behave differently. Faster to rank than category guides (two to five months is common), and they convert several times better than general content.

They also carry legal and maintenance obligations everyone skips. Competitor claims need to be accurate and dated, and you’ll need a quarterly review cadence or you’ll be publishing wrong pricing about a competitor who will notice.

9. Webinars and virtual events

Work when you borrow someone else’s audience, mediocre when you don’t. A webinar to your own list is a nurture activity dressed as acquisition. A co-hosted session with a partner who has an audience you lack is genuine acquisition.

$3,000 to $15,000 per event all in, including promotion and staff time. Signal in two to six weeks.

10. Newsletter sponsorship

Undervalued for niche products. A $2,000 slot in a newsletter read by four thousand of exactly your buyers frequently outperforms $20,000 of LinkedIn, because the audience is pre-filtered by someone with reputation at stake.

Hard to scale, easy to test. Start with three sponsorships in a quarter and measure with a dedicated landing page, since attribution here is otherwise hopeless.

11. Community and forums

Reddit, Slack groups, industry forums. Genuine long term value, near-zero short term measurability, and it punishes anyone who shows up to promote rather than participate.

Twelve to eighteen months before it produces traceable pipeline. Fund it as brand investment or don’t fund it at all, but be honest about which you’re doing.

12. Product-led signup loops

For sub-$20K ACV products with self-serve onboarding, the shared artifact or invite path frequently becomes the cheapest acquisition channel in the business. Payback under six months is achievable because the marginal cost per acquired user approaches zero.

Requires the product to produce something worth sharing. You cannot retrofit this with a referral banner.

13. ABM programmes

$60,000 to $250,000 a year for tooling, content and coordination across a named account list. Works above $75K ACV where a single won account repays the entire programme.

Below that band it’s an expensive way to run display ads at companies who never see them. The 6sense and Demandbase category is genuinely useful at enterprise ACV and genuinely wasteful below it.

14. Conference booths

The most overrated channel at every ACV band, and I’ll defend that position.

A mid-tier booth plus travel, freight, staff time and swag typically runs $40,000 to $90,000. What you get back is badge scans, and a badge scan is a contact record, not a lead. Conversion from scan to opportunity commonly sits in low single digits.

Turn-on sequence by ARR band

ARR band	Turn on	Keep running	Do not touch yet
Under $1M	Founder outbound, marketplaces, BOFU pages	All three	SDRs, LinkedIn, events, ABM
$1M to $5M	Paid search, integration listings, comparison pages	Marketplaces, BOFU SEO	ABM, conference booths
$5M to $15M	First SDRs, LinkedIn, webinars, newsletters	Everything above	Booths unless ACV above $75K
$15M+	ABM if ACV supports it, community, brand	Selective pruning of paid	Nothing, but audit ruthlessly

The mistake at every band is turning on the next channel before the current one is working. A team running paid search badly and then adding LinkedIn has two channels running badly and no idea which is at fault.

The three channels most teams should cut

Display retargeting beyond a small budget. It shows impressive attributed numbers because it retargets people already heading to your site. Run a holdout test. The numbers usually collapse.

Broad top of funnel content. Articles aimed at people with no buying trigger, now competing directly with AI summaries that answer the same question without a click. Keep the bottom of funnel work, cut the rest back hard.

Conference booths under $50K ACV. Covered above. The arithmetic almost never works.

Cutting all three typically frees 15 to 30 percent of a mid-size marketing budget with no measurable pipeline loss, which makes it the fastest efficiency gain available to most teams.

Honest limitations of this ranking

Every number here is a range, and ranges hide the thing that matters most, which is execution quality. Two companies running the same channel at the same spend routinely see triple the difference in cost per opportunity, and no table will tell you which one you are.

Vertical SaaS breaks several of these rows. If you sell to 1,400 possible buyers, marketplaces have no coverage, search volume barely exists, and the entire ranking reshuffles toward outbound, community and events. Treat the table as a horizontal B2B default.

What to do this week

Pull last quarter’s spend by channel, compute cost per opportunity for each, and divide by your ACV. Anything above 15 percent goes on a watchlist with a decision date.

The SaaS marketing channel ROI index has the comparative return data, SaaS marketing benchmarks covers the wider set, and SaaS Marketing Costs breaks down what each line should cost. Model the chain with the B2B SaaS cost per lead calculator or the simpler Cost per lead calculator, then rebuild next quarter’s allocation with the SaaS marketing budget template.
