I am always on the lookout for cost and time effective ways that I can market my software products. Previously, I have had quite a lot of success with Google Adwords Pay Per Click ads. However, the law of shitty clickthroughs means that advertising platforms generally get less and less profitable (for the advertisers) over time. And Google Adwords is a case study of that law in action. As Reddit is a less mature advertising platform, I thought it might still offer opportunities for a decent return. So I decided to experiment with advertising my data munging software, Easy Data Transform, on Reddit.

[By the way, I understand that nobody goes to Reddit because they want to see ads. But commercial products need to market themselves to survive, and Reddit probably wouldn’t exist without ads. Yay capitalism.]

Setup

The basic process to get started with Reddit Ads is:

• Sign up for a Reddit Ads account.
• Enter your details and credit card number.
• Create a campaign.
• Create one or more ad groups for your campaign. Choose a bid for each ad group, which countries you want it shown in and who you want it shown to.
• Create one or more ads for each group.
• Add the Reddit tracking pixel to every page of your website.
• Set up conversion goals.

All pretty standard stuff for anyone who has used Google Adwords. The twist with Reddit is that you can advertise to communities (sub-Reddits), rather than based on search keywords. For example, Easy Data Transform is a much better tool for most data wrangling tasks than Excel, so I can bid to show ads targeted at Excel users in communities such as: reddit.com/r/excel/ and reddit.com/r/ExcelTips/.

Like Adwords, there are various ways to bid. I don’t want the advertising platform to set the bid prices for me (because I’m not insane), so I opted for fixed price bids of between $0.20 and $0.40 per click. Some of the ad groups suggested much higher bids than that. For example, the suggested bid for my Excel ad group is $0.79 to $4.79 per click!

However, Easy Data Transform is only a one time payment of $99. Paying more than $0.40 per click is unlikely to be profitable for me, especially when you factor in support costs. So that is the maximum I was prepared to bid. Also, the suggested bids are just the ad platform trying to push up the bid price. Something that anyone who has used Google Adwords will be all too familiar with. I was still able to get clicks, bidding significantly less than the recommended minimum.

I also set a daily maximum for each ad group, just in case I had messed up and added a zero in a bid somewhere.

I created multiple ads for each ad group, with a range of different text and images specific to the communities targeted. Here are some of the ones I ran in the Excel ad group:

Clicking ‘Learn more’ takes you to https://www.easydatatransform.com/.

I didn’t try to use edgy images or memes, because that isn’t really my style. There is an option to turn comments on below ads. As Reddit users are generally not well-disposed to ads, I didn’t try turning this on.

Based on hard-won experience with Google Adwords, I only set my ads to run in wealthy countries. I also restricted my ads to people on desktop devices as Easy Data Transform only runs on the desktop.

When Easy Data Transform is installed, it opens a page on my website with some instructions. So I used this to set up the Reddit conversion tracking to count the number of times a click ended up with a successful install of either the Windows or Mac version of Easy Data Transform.

I monitored the performance of the ads and disabled those that has poor click through or conversion rates and made variants of the more successful ones. Darwinian evolution for ads. I ended up creating 70 ads across 15 ad groups, targeting 50 communities.

I wasted an hour trying to get Reddit to recognize that I had installed their tracking pixel. But, overall, I found the Reddit Ads relatively simple to setup and monitor. Especially compared to the byzantine monstrosity that Google Adwords has become.

Reddit advertises a deal where you can get $500 of free ads.

But the link was broken when I clicked on it. Someone else I spoke to said they had tried to find out more, but gave up when they found out you had to have a phone call with a sales person at Reddit.

Results

I ran my experiment from 08-Jul-2025 to 31-Jul-2025. These are the stats, according to reddit.

Spend	$851.04
Impressions	490,478
Clicks	3,585
Windows installs	177
Mac installs	63
Total installs	240
Click Through Rate	0.73%
Cost Per Click	$0.24
Click to install conversion rate	6.59%
Cost Per Install	$3.55

I generally reckon that somewhere around 10% of people who install are going on to buy. So $3.55 per install would mean around $35.50 cost per sale, which is reasonable for a $99 sale. So that all looks quite encouraging.

But, comparing the Reddit number to the numbers I get from Google Analytics and my web logs, I think the Reddit numbers are dubious. At best. In a week when Reddit says it sent me 1174 clicks, Google Analytics says I received 590 referrals from Reddit and my web log says I received 639 referrals from Reddit. Some of the difference may be due to comparing sessions with clicks, time zones etc. But it looks fishy.

The discrepancy is even greater if you look at conversions. The total installs per week reported by Google Analytics and my web logs didn’t go up anything like you would expect from looking at the Reddit conversion numbers. If you dig a bit further, you find that Reddit uses ‘modeled conversions‘ to:

“Gain a more complete view of your ads performance with modeled conversions, which leverages machine learning to bridge attribution gaps caused by signal loss.”

Uh huh. Sounds suspiciously like ‘making shit up’.

And then there are the sales. Or lack of. I don’t have detailed tracking of exactly where every sale comes from. But I estimate that my $851 outlay on ads resulted in between $0 and $400 in additional sales. Which is not good, given that I don’t have VC money to burn. Especially when you factor in the time taken to run this experiment.

The top 5 countries for spend were:

1. Italy
2. Spain
3. France
4. Germany
5. Singapore

The US only accounted for 0.28% of impressions, 13 clicks and $3.81 in spend. Presumably because the US market is more competitive, and I wasn’t bidding enough to get my ads shown.

You can look at various breakdowns by country, community, device etc. This is helpful. But some of the breakdowns make no sense. For example, it says that 41% of the click throughs from people reading Mac-related communities were from Windows PCs. That sounds very unlikely!

But the worst is still to come. Feast your eyes on this Google Analytics data from my website:

	Average engaged time per active user (seconds)	Engaged sessions per active user
Google / organic	33	0.75
Successfulsoftware.net / referral	31	0.74
Youtube.com / referral	27	0.86
Chatgpt.com / referral	24	0.69
Google / CPC	16	0.65
Reddit / referral	8	0.25

8 seconds! That is the mean, not the median. Yikes. And 75% of the sessions didn’t result in any meaningful engagement. This makes me wonder if the majority of the Reddit clicks are accidental.

I had intended to spend $1000 on this experiment, but the results were sufficiently horrible that I stopped before then.

If I had spent a lot of time tweaking the ad images and text, landing pages, communities and countries, then I could probably have improved things a bit. But I doubt I could ever get a worthwhile return on my time and money.

If the lifetime value of a sale is a lot more than $99 for you, or your product is a good fit for Reddit, then Reddit Ads might be worth trying. But be sure not to take any Reddit numbers at face value.
