# Use cases: marketing operations, QA and data entry

## Where computer-use agents earn their keep

The best use cases share four traits: **repetitive** (done weekly or daily), **varied interfaces** (too many sites or UIs to script cheaply), **verifiable output** (you can check the result), and **tolerable blast radius** (read-only or reversible, or gated). This lesson walks through proven patterns in three areas, each with a task template, guardrails and a metric.

## Marketing operations

**1. Campaign QA across landing pages.** Before and during a campaign, check every landing page for the right offer, working CTA, correct UTM parameters on outbound links, tracking tags firing, consent banner behavior and mobile layout. Pattern: hybrid (script extracts, model judges), with screenshot evidence.

**2. Listings and profile consistency.** Compare business details (name, address, phone, hours, links) across Google Business Profile, directories, marketplaces and social bios. Read-only; output a mismatch table for a human to fix, ideally via official APIs where available.

**3. Competitor and pricing monitoring.** Record competitor offers and public prices on a schedule. Respect robots.txt and terms of service, rate-limit politely, collect only public information, and never log in to competitors' systems with fake accounts.

**4. Ad and content compliance checks.** Check that live ads' landing pages include required disclosures (for example #ad or paid partnership labels for influencer content under FTC, ASA/CAP or local guidance), correct pricing and terms, and no expired promotions.

**5. Platform admin chores with no API.** Downloading reports from tools that lack exports, updating many listings in a legacy portal. Use approval gates for any write.

## QA and product teams

**1. Exploratory testing.** Give the agent a persona and goal ("a first-time buyer in Jeddah using Arabic, on a mobile viewport, wants to buy a gift and pay cash on delivery") and have it narrate friction points with screenshots. It finds issues that scripted tests do not look for. Treat findings as leads for humans to confirm.

**2. Accessibility smoke tests.** Combine automated checkers (such as axe-core) with an agent trying to complete key tasks using only accessibility-tree actions and the keyboard.

**3. Self-healing suggestions** for brittle end-to-end tests (module two).

**4. Cross-browser and localization checks.** Right-to-left layout in Arabic and Urdu, currency formats, translated error messages.

## Data entry and back office

**1. Form filling from structured sources.** Enter orders, shipments, applications or registrations into portals that have no API, from a spreadsheet or CRM export. Use per-record checkpoints, validation before submit, approval gates for submission, and read-back verification.

**2. Document-to-portal workflows.** Extract fields from invoices or forms (with a document model), then enter them. Keep a human verification step for low-confidence fields.

**3. Reconciliation.** Compare a portal's records with your system of record and report differences.

## A reusable task template for marketing QA

```yaml
# campaign_qa.yaml (consumed by your harness)
task_id: eid-campaign-qa-v3
goal: Verify each landing page shows the Eid offer and has working tracking and consent.
inputs:
  urls_file: eid_urls.txt
  expected_offer: "Eid collection: free delivery over AED 200"   # illustrative
  expected_utm_source: "meta"
constraints:
  allowed_domains: ["www.example-store.ae"]
  allowed_actions: ["navigate", "screenshot", "scroll", "click_non_submitting"]
  forbidden: ["submit forms", "log in", "add to cart"]
checks:
  - offer_text_present
  - primary_cta_resolves_200
  - outbound_links_have_utm
  - consent_banner_offers_reject
  - mobile_viewport_no_horizontal_scroll
output_schema: {url: str, checks: dict, issues: list, evidence: list}
escalate_if: ["page returns 4xx/5xx", "login wall", "unexpected payment page"]
budget: {max_steps_per_url: 25, max_cost_usd_total: 5}
```

## Worked examples by region

- **UK agency**: weekly QA of 150 client landing pages, catching expired offers and broken UTM parameters before clients notice. Output feeds the account managers' Monday checklist.
- **Pakistani e-commerce brand**: exploratory QA of Urdu and English checkouts on mobile viewports, surfacing a right-to-left layout bug on the address form.
- **UAE logistics firm**: entering shipment bookings into a carrier portal from the TMS export, with human approval before each submission and read-back verification of the booking number.
- **US creator business**: checking that every sponsored video's link-in-bio landing page has the correct disclosure and discount code.

## Choosing and sizing a use case

Score candidates 1 to 5 on frequency, time per run, interface variety, verifiability and risk (inverse). Start with the highest total that is read-only. Estimate value as (hours saved per month × loaded hourly cost) + (errors avoided × cost per error), minus build, run and review costs. Use your own measured baseline, not vendor claims.

## Pitfalls

- Scraping that breaches terms of service or collects personal data without a lawful basis.
- Automating a broken process instead of fixing it.
- Skipping the human review step on outputs that drive client-facing decisions.

## How to measure success

Per use case: runs per month, verified success rate, human minutes per run (review plus fixes) versus the manual baseline, issues caught before customers noticed, and cost per run.

### Use cases that pay off

You've learned how agents work and how to make them safe. Now the practical question: where do they actually earn their keep? In this lesson you'll see proven use cases in marketing operations, QA and data entry, a reusable task template, and a simple way to choose and size your first project.

### Four traits of a good use case

Good use cases share four traits. They're repetitive, done every week or every day. They span varied interfaces, too many sites to script cheaply. Their output is verifiable, you can check it. And the blast radius is tolerable: read-only, reversible, or gated behind approval. If a candidate fails two of these, park it.

### Why it matters

Why does this matter? Because the first use case sets the tone for everything after it. Pick a flashy, risky one and a single mistake can make the whole organization wary of agents for a year. Pick a repetitive, checkable, low-risk one, and you build evidence, trust and skills that make the next use case easier. Choosing well is the fastest route to real value.

### Your first intern

Here's an analogy. Think of hiring your first intern. You wouldn't hand them the company credit card and the client relationships on day one. You'd give them something repetitive, useful and easy to check, like compiling a weekly report, and you'd review their work. As they prove reliable, you give them more. Picking your first agent use case works exactly the same way.

### Simple example: 15 landing pages

A simple example of campaign QA. You launch an Eid promotion across fifteen landing pages. The agent checks each page for the offer text, a working call-to-action link, UTM parameters on outbound links, and whether the consent banner offers a reject option. Output: a table of fifteen rows, each with pass or fail per check and a screenshot. Two pages still show last month's offer, and one CTA link is broken. You fix three things before customers notice, and the check took minutes of human review.

### Marketing operations

In marketing operations, the standout is campaign QA. Before and during a campaign, check every landing page for the right offer, a working call to action, correct UTM parameters, tracking tags, consent banner behavior and mobile layout. Close behind: listing consistency across your business profile, directories and marketplaces; competitor price monitoring, done politely and only on public information; disclosure checks on sponsored content, under rules like the FTC's in the US and the ASA's in the UK; and admin chores in tools that have no API.

### QA and product

For QA and product teams, try persona-driven exploratory testing. Tell the agent: you're a first-time buyer in Jeddah, using Arabic, on a phone, buying a gift and paying cash on delivery. Then have it narrate every point of friction, with screenshots. It finds things scripted tests never look for. Treat those findings as leads for a human to confirm. Add accessibility smoke tests, self-healing suggestions for brittle tests, and right-to-left and localization checks for Arabic and Urdu.

### Data entry

In data entry and back office, agents fill portals that have no API, from a spreadsheet or CRM export: orders, shipments, applications. The safe pattern is a checkpoint per record, validation before submit, human approval for each submission, and reading back the result to verify. Related patterns are document-to-portal workflows, where low-confidence fields go to a human, and reconciliation, where the agent reports differences between a portal and your system of record.

### A reusable task template

The lesson text includes a reusable task template for campaign QA. It names the goal, the inputs, the allowed domains and actions, the forbidden ones, the exact checks, the output schema, when to escalate, and a budget for steps and cost. Write one of these for every use case. It becomes your spec, your test plan and your audit record in one file.

### Choose and size

Some quick examples. A UK agency runs weekly QA on a hundred and fifty client pages and catches expired offers before clients do. A Pakistani e-commerce brand found a right-to-left layout bug in its Urdu checkout. A UAE logistics firm enters carrier bookings with approval before each submission. A US creator checks that every sponsored link lands on a page with the right disclosure and discount code. To choose yours, score each candidate one to five on frequency, time, variety, verifiability and risk, and start with the top read-only one. Estimate value from your own measured baseline.

### Sizing, illustrated

Let's size a use case with illustrative numbers. Say campaign QA takes a coordinator about four hours a week today. The agent version needs about forty-five minutes of human review. That's roughly three hours saved weekly. If it also catches one expired offer a month before customers see it, add the value of avoiding that complaint or refund. Subtract model and infrastructure costs, and the upkeep time. These figures are illustrative; plug in your own measured ones.

### Fix the process too

One more thing: don't automate a broken process. If campaign pages keep launching with wrong offers because nobody owns the brief, an agent will catch the mistakes faster, but the mistakes will keep coming. Use the agent's findings as data to fix the upstream process: clearer briefs, a pre-launch checklist, an owner per page. The best agent programs shrink the problems they were built to find.

### Three mistakes

Three common mistakes with use cases. First, scraping that breaches terms of service or collects personal data without a lawful basis, which can turn a productivity win into a legal problem. Second, automating a broken process instead of fixing it. Third, skipping the human review on outputs that drive client-facing decisions. The agent's report is a draft for a person, not a verdict.

### Try this now

Try this now. List five candidate use cases from your own work. Score each from one to five on frequency, time per run, interface variety, verifiability and risk, where lower risk scores higher. Add up the scores and circle the highest one that can start read-only. Then write a task template for it, like the campaign QA example in the lesson text: goal, inputs, allowed and forbidden actions, checks, output schema, escalation rules and budget.

### Recap

Recap. Pick use cases that are repetitive, varied, verifiable and low-risk. Marketing QA, listing checks, exploratory testing and gated data entry are proven starting points. Write a task template for each, and measure human minutes per run against your manual baseline. Your next step: score five candidates from your own work and write the template for the winner. Next, the business case and governance that let you scale.
