@chunhe889 Why not start at the bottom of the funnel and get your skin in the game with some ads? You'd know whether your idea has legs.
Better to spend $1,000 - $2,000 and get some traffic/user data than to write blog posts for 6 months or to keep on developing for months with no users.
Create a Google Ads account.
Use Google Tag Manager and Google Tag Assistant for conversion action setup and testing. You'll need a conversion action in the Google Ads platform, a trigger, and a tag in GTM link the two together with the provided IDs. Test with Google Tag Assistant and make sure they fire each time.
You probably want Account Signups or Request a Demo as your conversion actions. Purchases would be even better. But you'd have to gate your app behind the $5 per month paywall.
[sup]Honestly, having purchases as your conversion action is not a bad idea because it would let you create campaigns that optimize to people making the actual monthly purchase rather than on sign-ups. Why? Just because someone signs up doesn't mean they'll buy.[/sup]
Next, create a Search campaign, Target USA, set your location preferences to in or regularly in, pick Manual CPC as your bidding strategy if you don't mind learning a thing or two about the Google Ads auction, bidding, and how keywords work. Use Maximize Clicks otherwise. Then, write your Responsive Search Ads.
Target these keywords with phrase match as the match type. Src: Keywords Planner

N/A, few companies advertise on this keyword.
Pick a daily budget of at least $50 per day.
Assuming you picked Maximize Clicks, your campaign will now try and get you as many clicks as possible on these searches at the lowest Cost per Click it can get you. Analyze your data after a week or two and if all goes well, you might add 3-9 new freemium users per day, depending on your actual avg. CPC and website conversion rate.
Will you show up at the bottom of the Search Engine Result Page and potentially get low-quality clicks? Maybe. You can use Manual CPC and snipe for good placements if you want more control. But as with all business endeavors, there's risk.
