Reddit vs Google Ads for SaaS: Which Should You Pay For First?

Most founders pick Reddit Ads for one reason: the clicks look cheap.

Then the money runs out, the dashboard shows a pile of clicks, and Stripe shows nothing. I've watched it happen, and I've been the one running the campaign.

In this guide, I'll tell you which one I'd actually pay for first, what a fair test costs, how fast you can tell if it's working, and why the best Reddit results I've ever seen didn't come from ads at all.

Reddit Ads or Google Ads: which should a SaaS pay for first?#

If you're going to pay for traffic, start with Google Ads. If you're bootstrapped and can't afford a real ad test, skip both and start with organic Reddit.

That's my answer for most SaaS products, B2B or B2C. Your niche can change it, so here's the side by side:

Google Ads (Search)

Reddit Ads

Organic Reddit

Who you reach

People already searching for a solution

People browsing communities, mostly not shopping

People asking for advice in threads

Intent

High. They typed the problem

Low to medium. You interrupt them

High when you answer the right question

How people react

Neutral. Ads are expected

Often skeptical. Many users came for real opinions

Positive when you're genuinely useful

Main cost

Clicks, which can be pricey

Clicks, often cheaper

Your time and know how

Biggest risk

Paying for the wrong keywords

Cheap clicks that never convert, plus community backlash

Bans if you spam or break subreddit rules

Best for

Products people already search for

Niche audiences that live in specific subreddits

Early users, trust and word of mouth

THE REAL QUESTION ISN'T REDDIT VS GOOGLE ADS. IT'S PAID SEARCH VS ORGANIC REDDIT. Most comparisons miss that, so this one won't.

Why Google Ads usually wins the paid fight for SaaS#

Google Ads reaches people at the exact moment they're looking for a fix. Reddit Ads reaches people who came to read opinions, not to shop. That intent gap matters more than any CPC difference.

Google clicks aren't cheap, though. WordStream's 2026 benchmarks, based on 13,474 US search campaigns from April 2025 to March 2026, put the median cost per click at $5.42 and the median cost per lead at $66.69. Those numbers cover all industries, not just SaaS, so treat them as a rough reference, not a target.

I've run Google and Meta campaigns with monthly budgets of roughly $1,000 to $2,000. In my experience, if you're buying traffic, Google gives you the most for your money. Meta can work too, but it costs more for what you get.

Where I start with keywords#

1. Your main keyword. The phrase that describes what your product does.
2. Your brand name. So nobody else grabs the top spot when people search for you.
3. Competitor names. Google lets you bid on trademarks as keywords, though using a competitor's name in your actual ad text is restricted.

Competitor keywords are underrated. Say a competitor has 20,000 users. Some of them are searching that name every day. Your ad shows up above the competitor's organic listing, and plenty of people click the top result just to see what's new or cheaper.

One honest note: that's a sponsored spot. It doesn't make your site outrank theirs organically.

One myth to drop#

Running Google Ads won't boost your organic rankings. Google keeps ads and organic search as separate systems. What ads do give you is fast data: which keywords people click, and which ones turn into signups. Use that to rewrite your homepage and landing pages around the words buyers actually type.

Why Reddit Ads often disappoint SaaS founders#

Reddit Ads often give you cheaper clicks, but cheap clicks aren't cheap customers. In my experience, people come to Reddit for honest opinions from real people, and an ad is the opposite of that.

I tested Reddit Ads for an AI tool for students. We spent roughly $300 to $400. The clicks were cheaper than what we were seeing on Google, but the campaign didn't deliver what we needed, so we moved the budget elsewhere.

The bigger problem was timing. AI writing tools had a reputation problem in academic communities back then. We got banned from several subreddits, and eventually the ad account was suspended. I can't say for sure the backlash was the exact reason, but it didn't help.

Walking into a hostile subreddit with an ad is like showing up at the Red Wedding as a Stark. You think you're a guest. You are not.

I'll be honest about my bias too. As a Reddit user myself, I scroll right past most Reddit ads. I've stopped on plenty of Google and Meta ads, but rarely on a Reddit one. That's one person's habit, not a study, but it matches what I've seen across the products I've worked on.

Reddit Ads can still work. If your audience lives in a specific subreddit and your creative feels native to it, you might do fine. Just know that A LOW CPC MEANS NOTHING UNTIL SOMEONE PAYS YOU. I call this cheapclickitis, and it's the most common way founders burn their first ad budget.

Organic Reddit vs paid ads: the comparison that actually matters#

For an early SaaS, organic Reddit can beat paying for either platform. You're not renting attention. You're earning trust in the threads where buyers ask for advice, and good threads keep sending people for months.

With that same AI tool for students, the ads flopped, but organic Reddit became our strongest channel. By our internal count, our first 30,000 to 40,000 users came from Reddit activity. Our community there was one of the strongest in the niche.

We also saw people discover us on Reddit, then search our name on Google and sign up from there. I can't put an exact number on that lift, but it showed up again and again.

Why Reddit threads reach further than Reddit#

• Americans use it. Pew found 26% of US adults use Reddit as of 2025, up from 18% in 2021.
• Google shows it. Ahrefs analyzed 145 million US search results and found the Discussions and forums box in 11.7% of them. Reddit appeared in 87.8% of those boxes.
• AI tools read it. Google signed a deal for access to Reddit's data, reported at the time to be worth about $60 million a year. OpenAI announced its own partnership with Reddit to bring Reddit content into ChatGPT.

One caveat. None of this means a popular post will automatically show up in Google or get quoted by ChatGPT. It means good Reddit threads have a real shot at living far beyond Reddit. An ad disappears the moment you stop paying.

How I make organic Reddit work#

• Answer the question people are already asking. If someone describes the exact problem your product solves, a helpful answer gets attention.
• Share real experiences, not pitches. "Here's what I tried, here's what worked, here's where my first 100 users came from" beats "Check out my tool!" every time.
• Leave the link out, at first. Be useful. When people are curious, they'll ask or search your name.
• Learn each subreddit's rules. Many communities ban promotion. Breaking that rule gets you banned, which is exactly what happens to most spammers.
• Disclose your connection. If you're promoting a product you work on or for, say so.

Posts that spark real conversation tend to keep climbing. More comments bring more upvotes, which bring more readers. That's the loop you want.

If you'd rather have someone run this for you, here's how I handle Reddit marketing for SaaS without getting banned.

How much should you spend on a first ad test?#

For a quick first read, $10 to $20 a day for about 10 days is enough. That's $100 to $200. It won't prove a channel can grow your SaaS profitably, but it will tell you if your creative, targeting and landing page are badly off.

What you get from a small Google test is worth more than the signups: a list of keywords people actually click on. Build your pages around those.

How fast can you tell if an ad works?#

You can spot a broken ad in one to three days. You can't judge a whole channel that fast.

Here's what I watch early:

• Video ads. The first three seconds. My personal rule: if the hook isn't holding the vast majority of viewers, I don't wait. We rework the hook, tighten the edit, and speed up the pacing, just not so much that people can't follow.
• Image ads. Click through rate and cost per click. These can take two to three days to settle.

But early numbers only tell you about the ad. Whether the channel brings paying customers needs real conversion data, and that takes longer. Don't kill a channel on day two, and don't scale one before anyone has paid you.

What you're judging

When you can tell

What to look at

Is this ad broken?

1 to 3 days

Hook retention, CTR, CPC

1 to 2 weeks

Signups, activation

Does this channel make money?

Weeks to months

Paying customers, cost per customer

What mistakes do founders make with each platform?#

On Google, it's stuffing in too many loose keywords. On Reddit, it's assuming a community will welcome you just because it talks about your topic.

Google Ads mistakes#

• Keyword stuffing. Throwing in every vaguely related keyword and paying for clicks from people who'll never buy. Keep your keywords tight and relevant.
• Cringy creative. Video ads with no hook, rough editing and no captions. If your ad looks like a Saul Goodman late night commercial, minus the charm, people scroll right past.
• Set and forget. Launching a campaign and checking it a month later. Look at it regularly and fix what's leaking.

Reddit Ads mistakes#

• Underestimating the audience. Redditors spot an ad instantly and aren't shy about saying what they think in the comments.
• Ignoring community mood. If a subreddit already dislikes your category, an ad won't change their minds. It'll give them something to aim at.
• Chasing cheap clicks. A $0.20 click that never converts costs more than a $5 click that does.

Should you run Reddit Ads and Google Ads at the same time?#

For a small SaaS, no. Splitting a small budget across two ad platforms means neither gets enough data to tell you anything.

The combo I actually recommend is different: organic Reddit plus Google Ads. Reddit builds trust and gets people talking about you. Google catches them when they go looking for a solution, or search your name after seeing you in a thread.

If a client insists on Reddit Ads anyway, I'll run them. It's their product and their call. But I'll tell them straight that I think their money works harder elsewhere. I'd rather give honest advice than take easy money, because trust is the whole job.

And if you're starting with Google, here's how I set up Google and Meta ads for SaaS so the budget goes to clicks that convert.

FAQ#

Are Reddit ads worth it for B2B SaaS?#

They can be if your buyers gather in specific subreddits and your ad feels native there. For most small SaaS teams, I'd put the same money into Google Ads or into organic Reddit first.

Is Reddit cheaper than Google Ads?#

Per click, Reddit is often cheaper. Per paying customer, it depends entirely on your product and audience. Compare cost per customer, never cost per click.

Can Reddit Ads replace Google Ads?#

Not usually. Google catches people actively searching for a solution. Reddit Ads interrupt people who are browsing. They do different jobs.

Do Google Ads help my SEO?#

No. Google keeps paid and organic rankings separate. Ads can teach you which keywords convert, which you can then use to improve your pages.

Can I get banned on Reddit for promoting my SaaS?#

Yes. Many subreddits ban self promotion, and repeated rule breaking can get your account restricted. Read each community's rules before you post.

Before you spend a dollar, check where you're stuck#

Ads pour more people into your funnel. If the funnel leaks, you're paying to make the leak bigger.
