## Key takeaways

- Demo one job to be done per video, not the whole product.
- Crop and zoom desktop recordings so the interface is readable on a phone.
- Match the landing page to the hook and tag every link with UTMs.
- Measure sign-ups, activation and trial-to-paid, not likes.

SaaS and web apps are harder to explain than a consumer game, but short-form video is one of the lowest-cost ways to show them. The principle is the same: **show one problem solved on the real screen.**

## Pick one job to be done

Do not demo the product. Demo a job: "Turn a spreadsheet into a dashboard," "Send an invoice in 20 seconds," "Schedule a week of posts." Each job is a video.

## Format ideas

- **Workflow speedrun:** the full job in 15 seconds.
- **Before and after:** the spreadsheet mess vs. the clean view.
- **Myth busting:** "You do not need an analyst to do this."
- **Role-based tips:** "3 things every marketer should automate."

## Make web apps readable on mobile

Crop desktop recordings to the active area, zoom the cursor, increase font size and avoid tiny sidebars. Otto auto-crops desktop captures for vertical video.

## Pick platforms by buyer

TikTok and Reels for discovery and prosumers, LinkedIn for decision-makers, YouTube Shorts for long-tail search. Reuse the same cut across them.

## Funnel basics

Video, then profile link, then landing page, then trial. Match the landing page headline to the hook and tag links with UTMs ([UTM builder](/resources/tools/utm-link-builder)).

## Metrics for SaaS

Track sign-ups, activation rate and trial-to-paid conversion, not just views. Understand payback with the [ROAS and LTV calculator](/resources/tools/app-roas-ltv-calculator).

## Frequently asked questions

### Does TikTok work for B2B SaaS?

Yes, when the content shows a specific workflow solved in seconds. Work-related problem and tool-demo videos draw professional audiences, even in B2B.

### What should a SaaS demo video show?

One job to be done from start to finish on the real interface, narrated in plain language, with the result visible at the end.
