7 High-Demand Businesses You Can Start Today

One of my favourite things to do is search through thousands of keyword combos to find business ideas that are in high-demand, with low competition.

Here’s 7 interesting opportunities I found this week:

Side note: My new dev agency only has 1 discounted web app package left. If you’re thinking of building one of these ideas (or your own), now’s a great time to reach out.

"invoice generator" = 56,000 monthly searches in the U.S (211,000 globally), 18/100 KD (keyword density score)

Idea: Build a free online invoice generator where users can instantly create professional invoices. With 56,000 U.S. searches and 211,000 globally, paired with a low keyword density of 18/100, this is a high-demand, low-competition niche. Upsell premium features like branded invoices, PDF exports, recurring billing, and multi-user accounts. Monetization can come from freemium subscriptions, display ads, or offering API access for larger businesses or marketplaces.

"flag quiz" = 5,000 monthly searches in the U.S (89,000 globally), 15/100 KD (keyword density score)

Idea: Create unique and visually engaging flag quizzes designed to go viral by encouraging users to share their scores on social media. With 5,000 monthly searches in the U.S and 89,000 globally — plus a low keyword density score of just 15/100 — there’s plenty of room to grow organically. While quiz sites exist, most are outdated or generic. You could differentiate with better UX. Monetize via partnerships with flag merchants, or by selling geography, education, and travel-related products.

"SEO audit service" = 3,100 monthly searches in the U.S (6,300 globally), 17/100 KD

Idea: Launch a niche marketplace where top SEO experts can list and sell their SEO audit services. Unlike automated tools, this would focus on high-quality, manual audits. You can monetize by taking a commission on each sale or offering premium listings for experts. With a high CPC of $25, this is a service buyers are willing to pay for, making it a solid opportunity if you curate the right experts and position the platform as a quality-focused alternative to generic SEO audit generators.

"wedding checklist" = 17,000 monthly searches in the U.S (29,000 globally), 16/100 KD (keyword density score)

Idea: Build a customizable online wedding checklist app where couples can plan their wedding tasks step-by-step. The app could include pre-made templates, automated reminders, and the ability to invite collaborators (e.g., family, wedding planner). With a low keyword density of 16/100, there’s room to rank and grow. Monetization could come from upselling premium templates and partnering with wedding-related services. You could also build a vendor marketplace.

"bartending jobs" = 37,000 monthly searches in the U.S, 0/100 KD (keyword density score)

Idea: Launch a niche job board focused exclusively on the bartending and nightlife industry. With 37,000 monthly U.S. searches and a perfect keyword density score of 0/100, this is an open lane for SEO-driven growth. The site can feature listings from bars, clubs, restaurants, hotels, and event venues — with filters for location, experience level, and job type. You can monetize via paid listings, featured placements, or by offering recruiting/staffing services for high-end venues.

Create a multi-niche influencer directory

Idea: Build a directory that helps brands connect with vetted influencers across multiple niches and platforms — from TikTok to Instagram to YouTube. For example, “tiktok influencers” gets 5,100 monthly U.S. searches (11/100 KD), “fitness influencers” 3,000 (1/100 KD), “fashion influencers” 2,000 (2/100 KD), “golf influencers” 1,700 (0/100 KD), and “food influencers” 1,500 (1/100 KD). That’s strong search intent spread across low-competition keywords. The directory could include influencer profiles with follower counts, engagement rates, niche tags, and contact options. Monetize via paid listings, pro tools for agencies, or a commission model on booked campaigns. Each sub-niche has room to rank individually, creating long-tail traffic opportunities as the platform grows.

"boat loan calculator" = 19,000 monthly searches in the U.S, 4/100 KD (keyword density score)

Idea: Create a clean, fast-loading boat loan calculator that helps users estimate monthly payments based on loan amount, term, and interest rate. With 19,000 monthly U.S. searches and a very low KD score of just 4/100, there’s strong demand with little competition. You can monetize through affiliate partnerships with boat financing companies, lead-gen forms for lenders, or even upsell API access to boat dealerships. Expandable into other verticals like RV, motorcycle, or jet ski loan calculators once you gain traction.
