I've tried writing and sharing a blog post on it and I've tried grinding via social media, but have had little luck.
Any advice?
1. Pay for it (ads)
2. Borrow it (distribution agreement with a third party, who has an audience)
3. Build it (organic/SEO, use your own audience that you started building years ago)
That's it. Every other way is either a hybrid of two of those (e.g. paying someone to email their big list) or is one of them deeper down. So it sounds like you don't have an audience, which makes #3 impossible. At this point you can either talk to a friend or business associate who has a good-sized list, and see if you can come to some sort of an agreement with them, you can pay for ads on a relevant platform or blog, or you can start building your list now.
Is your landing page for a [free] lead magnet, or a purchase? Purchases in the impulse buy range ($27-47, but for developers maybe up to $97) get you qualified traffic, and for really good sales copy can be more-or-less self-liquidation, e.g. you are earning in net revenue basically what you're spending on ads. But often times it's just to take the edge off the ad spend and make sure your list is super-qualified people, since they've already paid you money they're more likely to pay you more.
My email is in my profile and I'm happy to give you an unbiased opinion of your landing page - I have nothing to sell you, it would just be what I think of the copy, offer, design, etc.
I don’t think there’s a lot of cases where having a landing page up will rank somewhere and people would just sign up to be notified.
Definitely check out Indie Hackers and /r/SideProject as well.
Good luck!
Saw a few of such things done by friends/colleagues and they always did that by building community on twitter or other media first. So it was just the same group they already had. The less the site actually explained and gave to the user the more successful it was. Pure local hype.
On the other hand it was just used to generate more twitter/facebook traffic about how that pre-lauch was successful, but nothing ever launched. It was always just a tool to generate noise and traffic on other media.
For instance [beware, biased personal experience]: a friend announced a mysterious site/service on topics he already was loud about on social media - personal trainer in IT area. Got 50 000 signups for a newsletter in a few days, actual organic traffic - this I'm certain about. Never launched anything new. He just took that site down when everyone forgot and started consulting more openly. The only new "product" was a newsletter that was sent for a year or so with the same content he already published regularly on twitter. Now he earns money on teaching others to get similar good PR (and other less soft IT stuff). Apparently this is called "building community". Mostly IT people, btw..
I'm sure he achieved some goals and is successful personally, but if you are able to mobilize 50 000 people to get their emails spammed and none of them complains when you don't create ANYTHING new it does rise questions. What is your significant community worth, if they don't care at all? Is there anything you actually deliver when you are hired?
Another thing you could try is services like Betalist. For my last project it worked pretty well: i spent 120 EUR on paid promotion and got around 250 signups. I can't say that they were all relevant to my product, but around 30% signed up for the app and used it at least ones.
It is a fine line between spammy and getting people to hear about your stuff. If you click my account, I posted twice, with a big space between each post about my product with a pretty big update for each on HN. When you click people's accounts who have a high ranking show HN post, they seem to post 2 or 3 times in a row to get it to catch. I am not sure the secret.
My only advice is to look at the dropbox show HN and take that as inspiration that anything is possible!
You might also want to make the upside bigger for people who share with others. Some startups let folks jump the line if they refer friends. Don't turn people into annoying spammers, but consider why/how people would spread the word about your new thing. At the very least, give them easy share buttons.
From my understanding they initially targeted several specific demographics that might be interested in the product.
They then used that knowledge to see which groups they should increase as spend on based on how they responded and whether they signed up to get notified of the campaign launch.
In your case, it's probably book clubs. Try talking to them first, and make sure you have what they want.
If your target is yourself, and this is something you really want, then you should go ahead and just build a prototype. A prototype doesn't have to be complex - it can just be a shiny website built on top of Google Sheets. If you get only 1-3 sign ups, you can scrap it. If you're getting a thousand out of nowhere, then get to work.
So you can calculate the "cost of acquisition" - how much you need to spend on advertisement in order to get a new customer.
And based on that you can figure out whether you have a viable business.
I liked it very much while I was beginning my first StartUp project, unfortunately it is in italian, but I think you can use english subtitles.
The idea in a nutshell: You have the landing page, you invest some euros on FB/LinkedIn ads (or whatever social media you think your audience it's more linked to, either B2B or B2C).
See what happens.
LinkedIn also worked surprisingly ok if you have a decent sized network.
Finally, if your product fits a topic that's being discussed here on HN, we've seen that can easily drive 50+ your products landing page.
If it interests me enough, I will sign up. And I'm very conservative about that. The last thing I signed up to be notified about was the Flipper Zero kickstarter. (Yes they had their own launch page). But I don't remember where I found it, probably reddit.
I've started to get some traction though with constant tweaking of my landing page. Unfortunately unless you get some third-party recommendation you'll most likely have to pay for it at least for now.
I have been learning a lot more about the power of positioning a product correctly for an audience .. sometimes without changing the product itself much.
