I improved the game and functionality over time. The game has always been above the fold, but the content was greatly revise this past year. I've been doing a lot of optimizations on the game, but nothing big. After all, it's limited how much innovation can be done a game like that .
I started a solitaire website 5+ years ago. When Covid hit, I ended up finally putting ads on it. Since then it's been growing steadily and about half a year back I made it my full-time gig.
I've created an online solitaire platform (https://online-solitaire.com/) that's earning me $10k/m now. It started as a side-project 5 years ago, but I've recently gone full time on it.
It actually started as a Mac app 10 years ago and I choose to create a solitaire game because I had made a string of side-project that I didn't earn any money on, so I wanted to see if I could find a project that would actually generate some side-income.
I did it by scraping the Mac App Store so I could find apps that had a lot of downloads and bad reviews. I figured that if an app had a lot of downloads, but got bad reviews then I could create something better and there would be an audience for it. The app ended up making enough money that I've kept it as a side-hustle for all these years. I've written about how I picked the app here: https://www.indiehackers.com/post/how-i-grew-a-simple-solita....
I'm a bit late to the game on this thread, but here goes.
For the longest time I had a solitaire app for Mac that I ran as a side-hustle. A couple of years ago I programmed solitaire from scratch for the web. Fast-forward a few years and the site starts to generate some actual traffic. I then decide to put ads on it even though I thought you couldn't really earn money on ads anymore. It didn't generate a lot of money, but enough that I wanted to keep working on the site.
Today the site is earning $10.000/month from ads. It wasn't until the site started to earn $5.000/month or so that I actually started to talk to people about it.
I've kind of thought about the moral of it myself. I ended up integrating Stripe to let people remove the ads. For a blog that might not make sense, but for a solitaire website where some people play an hour or two a day, it makes sense. I think the lowest pricing I had was a one-time fee of $5 and basically no-one uses it. I'm super surpriced how few people use it. But if you won't pay for playing, you're gonna get ads . And from what I can see, people are fine with this arrangement.
It's intentional. The first 5 games are ad-free. Most of the ad-revenue are from people who stick, so I kind of try to give people the best experience the first 5 games.
I switched from Adsense to Freestar and have been very happy with them. I think you'll have to have a certain amount of volume to get signed with them, but it's difinitely another ballgame than Google Adsense.
Yes I have. Most solitaire games these days have an option of playing a fully random game or a winnable deal. The automatic deal when a user comes to the site is a winnable deal.
Congrats with the site. I've only just had a glance at it, but I think there's a lot you can do. Make it HTTPS first of all, research all keywords that relate to sudoku, write a long article about it and have it on the main page. Make sure you on-page SEO is good and keep doing off-page SEO (getting backlinks). If you want to take SEO a bit more seriously, read through a guide like this to start with: https://backlinko.com/seo-this-year. That's what I did to de-mystify SEO in the beginning.
I started with a lot less ads, but have since then put more on. I don't like it either, but people really don't mind it that much it seems. I also have an option where people can pay to remove the ads. Basically no one uses it.
