Getting a new app ready to sell, before spending on ads

A new receipt app for gadget sellers wanted ads in Lagos. We tested it first and found 8 problems, then built a fast landing page for sellers, switched on Google Ads and recruited 23 field marketers across five states.

The situation

The app lets phone and gadget sellers issue receipts that buyers can check, and lets buyers report stolen devices.

It had just launched, with no marketing in place. The founder asked for ads, but paid traffic sent to an untested app wastes money.

What we did

Advisory

Test the product first

Every ad click that lands on a broken sign-up is money lost.

  • Tested the app from sign-up to payment and sent a written list of 8 issues.
  • Recommended letting people in first and asking for ID only when they sell.
  • Flagged a missing data-consent step, which Nigerian data law expects. The founder added it within a day.
  • Flagged pages still showing the product’s working name. Fixed the same day.

Build

Build a landing page for sellers

Ads need a fast page that says one thing and can be measured.

  • Built a separate page for sellers, because the app’s own pages loaded slowly and shared badly.
  • Added cookie consent, analytics, ad tracking and link previews for sharing.
  • Scored full marks on Google’s quality checks in testing, and went live the day after it was built.

Grow

Start the launch

Sellers trade face to face in markets. Ads alone would not reach them.

  • Wrote the launch strategy and a field playbook with one goal: a paying seller.
  • Built and launched a Google search campaign, approved and live within a week of signing.
  • Listed the app on Nigeria’s biggest classifieds site.
  • Shortlisted 9 influencers and negotiated their quoted rates down by about two-thirds.

Grow

Recruit and equip field marketers

A marketer who can show the app working signs up more sellers than one who hands out flyers.

  • Advertised the roles and verified 23 marketers in Lagos, Ogun, Osun, Imo and Abuja within a month.
  • Gave each marketer a personal referral code, to trace every sign-up back to them.
  • Made 4 short how-to videos, a weekly report form and a group chat for the team.

Results

  • 8 launch issues found before any ad spend. The two most urgent were fixed within a day.
  • A seller landing page live in a day, with full marks in testing.
  • Google Ads live within a week of signing.
  • 23 verified field marketers in five states. Most came through referrals from other recruits.
